How to disable SIM notification telling you your number?
When I reboot my phone, I always get this message from Android:

Your number: +XX XXX XXXX XXXX

I'm on Android 9. How can I disable it? (I'm not changing SIMs or something, just plain reboot.) To clarify, this is not the usual notification that you get from other apps, but a simple popup (from the SIM card I presume). There is only one SIM card slot.

Export/save 200+ Samsung memos without selecting them one by one?
I would like to save 200+ memo from the default samsung application

What I did:

I already succedded to save memos one by one but it takes too long to do this for all of them, the process is the following:

Open the samsung memo application

Go into each Memo

Save it by sharing it (thought the three dots) to Google Drive.

What I wanna do:

Save all of them without reapeating the steps above 200+ times

Note: Any ways to save/export them on a more successful way or to use them from another "memo application" are welcome!

edit: I know how to save one memo (as explained above), but I'm looking for a way to automate it or extract a large quantity of them at the same time.

is eMMC dead?Cant fix encryprion unsuccessful
After seeing encryption unsuccessful error I tried to wipe, format but nothing changed.Then tried to flash firmware with sp flash tool.First error was "to format code are is forbidden in this phone".Then disabled preloader and flash again.Now error was "sddmmc_read_failed ,err code 3148".When I tried to emmc test on memory test tab, it was giving me error again.So probably my emmc is dead.

My question is it a certain death of emmc, or can it be repaired or replaced?If it cant be recovered, what should I do, what are the options?Thank you.

How does init knows when to relaunch a process?
I know the Zygote listens to a socket in /dev/socket/zygote in order to know when to fork a new process. I want to know how init usually does it.

I have a persistent process (not service) X whose PPID=1 which corresponds to init and everytime I kill it init relaunches it. Is it normal for init to start processes instead of services? If so how does it usually knows the process needs to be relaunched?

How to toggle portrait / landsape screen orientation with launchable command?
I would like to get screen rotation under manual control.

```<code>Action A: set portrait mode
Action B: set landscape mode
</code>```

Both actions with immediate effect, no menu, no confirmation, etc.

I would like to have these commands reachable as regular launchable app so I can add them into customizable actions in other apps, i.e. to on-screen drawer (Jina), as Bixby/Google voice command, Bixby button action etc.

Apps I reviewed put such rotation commands into toggle buttons area or to a widget. So they are not launchable on their own. Any idea how to get commands A and B (or one which toggles A/B) available as app?

问:
WiFi scan limits on LineageOS and LineageOS for microG
Starting with Android Pie, wifi scans are heavily throttled: the limit is up to four times every 2 minutes for a foreground app, and once every 30 minutes for all background apps combined. This has massive impact on apps that rely on WiFi for geolocation, mapping or other purposes (see e.g. this issue).

Does anyone happen to know if LineageOS (and its derivative LineageOS for microG) introduce any changes that relax these limits? (Especially since microG comes with location providers which utilize wifi.) Or do they simply copy that behavior?

WIFI handover between AP with same SSID on different channels
Using devices (Zebra Mobile TC25) running Android 7, I am having problems with the WIFI handover not happening.
The situation is that I have several access points set up with the same SSID but broadcasting on different channels.

As I walk around I would expect that the WIFI would connect to the strongest boradcasting AP. This is not happening.

Is this a consequence of the APs having the same SSID? Is it something to do with once a connection is established Android OS is not keen to switch even if SSID has same name, irrespective of signal strength?

Disable ringtone fade-in
My Moto Z2 Play includes a "feature" where call rings and alarm sounds start out nearly silent and increase to full volume over about five seconds. I have been unable to find any setting to change this behavior. Media audio (games, apps, etc.) is not affected.

In the stock clock app settings, I have "Gradually increase volume" set to "Never". I'm seems that there is an OS or hardware level setting or feature that is overriding the clock app setting.

I have found an app that purportedly solves this problem, but it requires an unsettling number of permissions to function. Is there no native way to disable this "feature"?

(I understand that this behavior provides utility for some people. For me, it merely ruins my ringtones and makes me more likely to miss calls.)

问:
How do I diagnose the last shutdown? adb root?
Everything I've read indicates /proc/last_kmsg used to be how, however that seems to have changed with Android 6.0 (I'm on 8.1). I've also seen reference to /sys/fs/pstore/console-ramoops for Android 6.0+, but I have no file called that. I can't ls the directory either, because apparently I don't have root shell with adb.

I've tried adb bugreport, but that doesn't seem to contain shutdown logs.
I've tried adb root, but I get the message:

```<code>adbd cannot run as root in production builds
</code>```

I have a Nexus 5x that is rooted, with TWRP and Magisk.

The only other suggestion I've seen is to edit '/system/build.prop' to include the line ro.debuggable=1, but I can't access that file either due to a lack of root access.

I've spent a week trying to sort this out. Surely it can't be this hard to find shutdown logs?


问:
Is there any way to return the AM/PM to my status bar?
This is specific to a carrier-locked (VZW) Samsung Galaxy Note 9 running v9.0 Pie. Samsung decided to take away the AM/PM indication in the status bar clock, likely to save space for the "hole punch". They didn't even see fit to make it an optional toggle. My web searches have returned no result apart that people other than just myself rely on it being there. Does anyone here have a solution of any kind? The key here is the ability to note the meridiem at a glance from any screen

Also: Yes, I know the "Always On" screen has faces that include AM/PM. That doesn't quite work for what I need.

And please, don't respond with "why can't you just look out the window?" like somebody in every other forum I've searched. Some of us don't have windows or operate on a normal human schedule.


问:
Difference between Android sensors (acceleration, gyroscope, rotation vector)
I have an Android 7 phone and I have written an Android application for recording the following sensor values:

```<code>Accelerometer (Sensor.TYPE_ACCELEROMETER)
Linear acceleration (Sensor.TYPE_LINEAR_ACCELERATION)
Gravity (Sensor.TYPE_GRAVITY)
Gyroscope (Sensor.TYPE_GYROSCOPE)
Magnetic Field (Sensor.TYPE_MAGNETIC_FIELD)
Rotation Vector (Sensor.TYPE_ROTATION_VECTOR)
Game Rotation Vector (Sensor.TYPE_GAME_ROTATION_VECTOR)
</code>```

I think the linear acceleration is the accelerometer minus gravity.

Can somebody explain what the difference between accelerometer, gyroscope, rotation vector and game rotation vector is? I've read the description in the Android documentation but it is not clear to me.

Moreover, can I use the magnetic field recordings to calculate some motion or position measurements which I'm not getting from the other listed sensor measurements?

How to make MIUI 10 Android 8 to auto-connect to a filtered WiFi AP?
I have a well working WiFi AP - actually a number of them. They are just fine themselves. Other iOS, Mac, Windows etc devices auto-connect just fine to it.

I also have Xiaomi mi5 with MIUI 10 Android 8. I have a bunch of them. Even after a factory reset, network reset, ensuring auto-connect is on - it does not re-connect to filtered WiFi when it is restarted or when it comes back from out of range distance.

Device says "connected, no internet" on first connection or manual connections after. DHCP is all OK, gets IP. network communication works.

I do understand that it says "no internet" because it tried to test with google servers and it failed. They are filtered here, and no I'm not in China. But the logic of "no google server"="no internet" is not correct. I am assuming that this is the reason it decides not to connect. But I am not sure. And also other Android 7 devices don't have this issue.

I ran out of ideas. Any clues on how to make this work?

What happens under the hood when a network request is made by an application
I'm interested in knowing what happens at the kernel level when an application makes a network request. While playing with strace I was hoping to find system calls like connect() to make a connection with an IP socket but instead, I found connections to local Unix sockets. From what I understand these connections may be for logging or any other system service. A lot of ioctl calls were also made which I'm guessing were for binder communication.

If the application is not servicing the request, is it being passed on to a system service using IPC which then sends back the response to the application? I was wondering if these requests could be captured at the system level using ptrace in order to monitor/block them.

I'm using a rooted device running Android 7.1.2

Alarm behaving very strangely
There is already another question like this (Alarm is disabled when device is switched off) but my question is slightly different from those.

In my new phone with Android 7.0 Nougat, I found something strange.

Suppose, I have set an alarm at 7:00 AM and at that time, the phone is switched off. I found that the alarm works absolutely fine - the screen turns on and the ringtone is played.

But, if the screen is not touched within about 15 seconds, such as, snoozing or dismissing the alarm, the screen turns off permanently, means that even if I hold down the power button, it doesn't turns on. But the ringtone continues to play.

Then I need to pull out the battery, reinsert it and again restart the phone.

Now I have somehow coped up with this issue by setting the Automatic power on time to two minutes before the alarm, that is, at 6:58 AM. But, that is not the solution, because I may sometimes set the alarm to before the power on time and I may forget to change the power on time. I am really fed up with this problem.

Why does this happens and how can I solve this issue?

I have Huawei P20 pro, and cannot receive WhatsApp messages unless I open the App
I have a Huawei P20 pro, and cannot receive WhatsApp messages unless I open the App.

A few points to note. There is intrusive data collection by many Apps and also usage of completely unnecessary network data - in my opinion.
So I restricted the default Network access. Huawei P20 Pro has (I assume other Huawei models + Andriod in general) a "Data saver" option. This restricts data access. However as a subsetting of this you can make an exception for the Apps you want. Using this path;
Settings => Wireless & Networks => Data usage => Data saver (On|Off) => On=>
Here choose for "Installed Apps" and "System Apps"

WhatsApp (and few others) selected for exemption, but still no messages unless I open the App. Any ideas?

Nokia 7.1 / Android 9 can't connect to specific local IP
My setup

Raspberry Pi running Pi-Hole on static IP 192.168.0.2

TP-Link Archer C7 router

IP - 192.168.0.1

2.4GHz and 5GHz bands using same SSID

DHCP setup

Default gateway - 192.168.0.1

DHCP range 192.168.0.100 - 192.168.0.199

DNS - 192.168.0.2

Subnet mask 255.255.255.0

Wireless AP isolation is disabled

I got a new Nokia 7.1 running Android 9. It connects to the wifi just fine (receives an IP like 192.168.0.103, DNS settings are set correctly) and can access the internet as well as certain local IPs such as the router admin page and other devices connected to the network, for example a Synology Diskstation.

I noticed I was getting ads on some web pages so tried to access the pi-hole dashboard to check things out. When I tried to access http://192.168.0.200/admin, I receive

This site can't be reached

http://192.168.0.2/admin is unreachable

  ERR_ADDRESS_UNREACHABLE

so that explains why I was getting ads but I cannot for the life of me work out why the phone cannot access this one specific local IP address.

My laptop which is on the same wifi network can access the pi-hole dashboard without issue.

This is my first Android 9 device so I might be missing a specific networking setting. Previously I had a Nougat phone that did not show any problems like this.

Update

Noticed the WiFi on the phone was constantly switching between 2.4GHz and 5GHz. Changed the router to use different SSIDs for each band which seemed to work well for a day but it's back to not connecting now.

Another update

Noticed whenever I'm having trouble with LAN connections, there's a TV.b wifi network which appears to be my Chromecast which means it too does not have a connection so this is looking more like an issue with the router.

问:
datadata is full - and doesn't let me remove files
A really old Smartphone having Cyanogenmod on it provides only about 400 MB space for data/data.

Now this space is full. df shows 0.0K of free space. The homescreen doesn't even appear, only errors appear on this smartphone.

It is a rooted phone (cyanogen) so I opened adb, got into an unused directory - whatsapp directory to be exact, it's already uninstalled but all data is left there - and tried to remove files to recover some space. I used a really large file with many MB.

First try

Sadly when I remove a file using rm I get Directory not empty.

This is disturbing because I don't remove a directory but a single file. The file doesn't appear any more but df still shows no free space.

Second try

On a website I found I better don't rm the file but empty is using the command

> filename = write nothing into the file.

I did - the file appears with size 0, du -sH tells me a different usage of this directory but df doesn't change.

Both doesn't work

After both tries I rebooted because who knows, perhaps things are rearranged after a reboot. But it's getting stranger - all files are back and have their original size.

Whatsapp is uninstalled, thus can't hold any references to the files.

What's going on here? It looks like my changes are kind of cached and don't affect the actual filesystem.

How can I get out of this and free some space in /data/data?

Btw I had this before. Then it helped to remove something unimportant from data/data and after the system rebooted without problems, I uninstalled unused apps and the whole thing went fine again.

Trying to delete files from other directories in /data/data/ also will not work.

Later...

I thought why not keep doing > filename for a while. Perhaps the filesystem needs time to spread the changes to all it's modules? (Stupid idea but I was desperate enough to try)

After some more large files I really got a change not only with du but finally some free space with df too.

After booting - the same as before. But I got curious what happenes if I do that for even more files. Wow ... after I freed ~100MB (of 400 - quite much) I noticed Trebuchet came back to work!

Space keeps beeing free after booting and I am able to remove the no longer needed folders in /data/data with rm -r.

But the initial question still is the same. Why did this have no effect after I started it for only a few files, why was everything reset after booting?

Unlocked bootloader, but still cannot boot or flash partitions
I just had some luck unlocking the bootloader on my Nokia 8.1. But it looks like I've accomplished nothing still. Previously when I attempted to flash a partition via fastboot or boot a boot image, I used to see:

```<code>flashing is not allowed in locked state

Now that I've successfully unlocked the bootloader (I can confirm via deviceinfo command and also via the 5 second warning before boot), I am encountering another roadblock:

```<code>flashing is not rooted for fused device
</code>```

It appears to be some sort of additional check. The device does show on screen (fastboot mode) that fuse = enable. Looks like this is some additional check for devices which have been unlocked  to prevent unauthorised use. I do not have any idea how to disable it. It probably comes from the Kernel level or probably somewhere else. Can somebody guide me to a direction which I should take next?
There should be some way to disable fuse.

Suppose, I am using my phone normally, the discharge rate is about 0.5% per minute. But, if I keep the mobile data connection on, then the discharge rate becomes about 5% per minute!!!.

Suppose, I am using my phone while I can see that the charge is 30%. Suddenly, I am notified of 0% battery and the Android OS shuts down. When I plug in the charger, it boots up and again shows 30% charge!!!
See this screenshot:

Suppose, I pull out the battery when the charge is 50%, after reinserting the battery, the charge either becomes 70% or as low as 20%, which are completely different from the previous observations.

All these happens when the mobile data remains on. I know that internet connection requires more energy, but according to me, it shouldn't be so much, isn't it?

I have two screenshots regarding this issue, where there are sudden sharp drops in the battery monitor graphs:

I had already factory resetted my phone and uninstalled every suspected battery draining programs, but it didn't solved the issue. Why does this happens and how to solve this issue? Please help me.

Note : My phone's model is Micromax Bharat 3 Q437 with pre-installed stock Android 7.0.

Acidentally uninstalled Google app on Android phone
I accidentally joined the beta program for the Google search app on android, in ordered to leave the program I had to uninstall the app and re-install it. When I did this, everything seemed to be working fine. But now when I open my Google assistant by holding the home button, it opens the Google app instead of the google assistant. So I  went to my device settings and tried to change my assistant app, it was set to Google as it was before and as it should be. I remember though that my phone (A Samsung Galaxy S5) came with the Google assistant pre-installed, so I looked for it on Google Play and found it uninstalled, so I installed it. Upon opening it told my device wasn't compatible and I need to be running a Google app that was 6.0 or higher, well, after checking I found I'm running 9.66 so I should be fine.
I don't know how a simple re-install would have broken my Google assistant so bad.
My phone is a Samsung Galaxy S5 running Android 6.0

I still haven't revised an answer to this question but I need it fixed, if I'm not clear enough or someone has a question PLEASE speak up.

Android won't connect to WiFi without Internet connection
The title says it: Android mobile phone won't connect to a WiFi network that doesn't have an Internet connection.

Our clients can't connect to a SoftAP network that our device creates. They see the SoftAP network, try to connect to it and are immediately removed from the network.

When I connect to the same SoftAP network, there is a warning that the said WiFi network doesn't have internet access. I then have to approve being connected to the said network. After I approve it, the application we use works fine.

Our clients are from Austria and we are based in Serbia. Don't know if this has anything to do with it. Also, almost all of our Android test devices are in developer mode. Again, don't know if this has anything to do with it, just trying to give as much info as possible.

问:
Split screen with Android Go pie
If I understand it correctly, the only thing that makes an Android ROM a "Go" version is the "ro.config.low_ram=true" entry, which brings several optimizations for low end devices and improves the performance by disabling some of the android features. One of them is the ability to display two apps simultaneously on the screen, using the split screen function.

So my question is - can only the split screen (or multi-window) function be enabled on an Android pie Go ROM, without disabling all other "Go" optimizations?

I'm using Resurrection Remix pie ROM on a Motorola Moto E 2015 phone.

问:
Managing /data/system/netpolicy.xml: what do these policies mean?
Seems like it wasn't clever of me to restore Data (policy/stats) with Titanium Backup. It has all that apps' unique UIDs from my previous system (actually, the same phone, but wiped and flashed) and now I'm starting to think that the same apps now have new UIDs, so the settings may be completely wrong, except the system ones, right? If I remove all the policies from the file, should I expect it to repopulate with defaults? Is this file controlled by that system app which allows to enable/disable cellular/wlan access?

What do all that policies mean? In case of manual setting. They're mostly 2048 and 3840, but there're 2816, 1792 and 768 too.

The reason why I've started to worry about it: Play Store is having some problems with the connection. To be exact, when I download starts it runs with Download Manager (uid: 10010, com.android.probiders.downloads) and the manager keeps saying «reconnecting», meanwhile other apps have no problems with the internet access. 10010 has 768 policy + it whitelisted (<whitelist>...</whitelist>), but at the same time I see that another app has 768 policy and it's some little game, I restricted it in internet access UI. However, it's not a total connection failure: it can download a couple of megs, then speed drops to a few kbs and only then it starts to say «reconnecting».

Maybe (just maybe) it has nothing to do with netpolicy.xml and it's something else causes the problem, but I don't know what else tbh.

Using Termux to Backups Android's Contact List
In Termux's website's main page, they write (among other stuff):

"use rsync to store backups of your contact list on a remote server"

This makes me wonder:

Android's Contact List is stored in an SQLite DB, which is a file on the phone's internal storage.

rsync synchronizes files.

So If I understand the required implementation behind this idea,

then what they mean by the quoted sentence, is that you can simply synchronize the whole SQLite DB file, to a remote server.

The problem is:

What happens when the day comes, and you need to Restore your Contacts DB?

I assume that Android will not let you copy the SQLite DB file that you saved aside, over the current (new, and empty) Contact List's SQLite DB file,

So how will we do the restoration?

I hope someone understood their idea in this sentence..

Completely compromised, but how?
I'm hoping a few geniuses out there can  lend there wisdom, I'm at a complete loss. Or maybe I'm the simple type.

I would like to assume I'm "hacked" but the situations I've been through lead me to believe what I'm dealing with is something a little different?

I'm seeing the strangest activity on my mobile device, as well as my fiances. And I believe whatever is plaguing our phones is also effecting my PC as well. Went from Note 8's which saw some of this bizaar behavior to two S10's for 2 weeks. After seeing the same things but worse in the S10's we actually switched carriers to another set of S10's and are having the exact same issues.

I noticed I was being properly updated either. And I couldnt view the previous update info which I should be able. And when we dropped our previous carrier the phone was able to update properly after about a day of being deactivated. Then with our new carrier, they rolled me back to the Feb edition if SE for Android status after already giving me March.

Android asks to re-enter WiFi passwords. Is my phone compromised?
I have a Galaxy S8 (SM-950F) with Android version 8.0.0. I have rooted the device with Magisk. I have a couple of Magisk modules, including Bixby remapper, F-Droid Privilaged Extension, liboemcrypto disabler, libsecure_storage companion, and Cloudflare DNS.

Recently I realized I have to re-enter my password for all WiFi networks even though the passwords are the same.

Is this simply a corrupted WiFi password file case (I have no Idea how the software on this phone manges passwords) or it could be that the phone is somehow compromised and some malware is forcing me to re-enter passwords in order to log them?

Install Split APK Manually
Recently I got to know a thing called split apks, and found the slices as invalid apk files, only the base is. Unfortunately, this means the usual default package installer is unable to handle this, and as such I got to know another thing called SAI, a split apk installer, capable of working with or without root. However, being curious, I wondered how it all worked internally, and began to do a bit of research. I didn't get far, but I got to find out about pm install commands, and I happen to have root access which is apparently mandatory if I am to go this path, as the terminal won't let me run pm install-create without first running su.

The next step is pm install-write all the slices, and this is where I fall. The most obvious way for me was to cd to the directory of the slices and pm install-write them one at a time, which didn't allow me to do so, and it seems to be expecting an int rather than a directory string.

Questions (TL; DR):

Can I install split apks without any extra apps (in my example, SAI)?

Am I in the right direction with pm install commands?

If the answer to question 2 is yes, what am I doing wrong, and what should I be doing instead (it seems to want an int instead of a directory string, not sure how to convert)?

Are there any other methods I can explore (preferably rootless, but root is also fine)?

Thank you for your time.

What can I do about broken touch input?
Lately a section of my phone's* screen has become unresponsive to touch.  Attempts to tap this untappable section result in a tap registering randomly around the problem area.

I can't draw in the area in Draw Something, and in Angry Birds, I can only aim my birds down as moving my finger down into the untouchable area results in the bird launching and the direction not changing.  Attempting to type with the phone on its side renders the letters around A,S,D,Q,W, and E unusable (virtual keyboard).  It is also impossible to select the "Users" tab on the mobile version of any SE site.

Android phone bahving strangely after passing metal detector
Phone is Oneplus One running Cyanogenmod (usure about the version but it should be the latest released to OpOs)

It all started after a metal detector scan - the phone would work for 20-30 seconds fine and then the screen would freeze indefinitely. Upon restart you could see the same behaviour. Once I was back home I plugged it to my laptop to try to retrieve some of the data and noticed that while connected the phone was absolutely fine.

This led me to believe the issue is software related so I did a factory reset. Unfortunately, after that the issue remained so I decided to try to flash the ROM. Started by turning off my phone so I can go into the fastboot menu but now after turning it off it won't turn back on.

I'm certain that it isn't a battery issue but I'm running out of options. Neither power + vol up or power + vol down work at the moment and connecting it to the laptop does nothing.

Any suggestions what to do next?

问:
How to change status bar icon color Android 9 [Pie]
I have a rooted oneplus 3t phone running Android 9 on a Lineage OS that I wish to style after the Fallout game franchise. I have many details figured out, except that the status bar color only seems to have the option of black or white. I would like the status bar icon colors to be green. This would especially be helpful as I've noticed that these white icons burn into the screen when a phone is old enough.

I first tried GravityBox which took forever to install only to find that they removed the status bar color tweaking features out of respect for other android releases that gave us this option by some other means... but Pie took them back.

I also tried Substrathum which gives an error page saying "Could not fall back to rooted mode. There are no other theme engines able to be utilized on this device at this current time." I found some sources which claimed to have it working on Pie, but their instructions were unclear or not specifically useful for getting past this error in Pie.

Can anyone help?

问:
Can apps bypass permissions and just use Google Play Services?
I was reading this answer, and the first comment under it, and wondered if apps can bypass their own app permissions and just get whatever data they want from Google Play Services.

What got me started with this was when I removed a bunch of permissions from Google Play Services and I started getting a notification saying "Accupedo is having trouble with Google Play Services. Try again." Clicking this notification brings up a screen saying "This app won't work properly unless you allow Google Play Services' request to access the following: Calendar; Camera; Contacts; Microphone; Phone; SMS. To Continue, open Settings, then Permissions, and allow all listed items."

As I search on the web and this site, I see everyone, seemingly blindly, saying "Oh, just give Google Play Services all the permissions possible and don't question them." But why? The whole point of having control over app permissions is to have control. This advice is simply giving up and letting Google do whatever they want.

As a concrete example, this one app does not request app permissions to my contacts, microphone, sms, camera, etc. However, Google Play Services' notification makes me think that this app is trying to get my SMS and camera and microphone. Since a simple step-counting app has zero reason to know my contacts or have access to my mic or camera, I would really like to know if they are trying to bypass even requesting app permissions and just getting everything they want from Google Play Services. If this is not the case, why would Google Play Services be sending me this notice?

By the way, originally, it included in the Google Play Services notification's permission list "body sensors." Since this made sense for a step-counting app, I went to Google Play Services and turned on that one permission. Now, "body sensors" is no longer in the list. This lends support to my idea that Google Play Services is receiving a request specifically for access to my camera and microphone (and others) from Accupedo while Accupedo has no such permission requested in the app permissions.

To be clear, this post is not about Accupedo. This question is about whether or not apps in general can simply hide from the user that they are collecting certain data or accessing certain parts of my phone without my awareness by getting everything from Google Play Services.

Any insights would be greatly welcomed.


问:
Massive increase in data usage with no change in behaviour
The primary purpose of data connectivity on my phone is checking email. I don't surf the Web when I'm "bored" (I occasionally look up something that I absolutely have to know that can't wait until I get home or to the office), and I don't watch videos. I also have the following configured:

Data Saver: on.

Wi-fi always connected at home, work and other places where I am routinely located.

Images turned off in my browser of choice.

Background data turned off for almost everything except my email app.

"Wi-fi only" mode in Maps.

Apps and updates only downloaded over wi-fi.

Back-ups off.

And possibly more, but the point is I have turned off everything that I can find.

For the past two years I was using Ting in the US and Lollipop (5.1), and was routinely using less than 100 MB of data a month. One month I used 112 MB -- one month! -- and I was shocked.

A couple of months ago I opened an account with Freedom Mobile (formerly Wind Mobile) in Canada. (I actually live in Canada, but was permanently roaming on an American network for philosophical reasons and because it was actually cheaper.) In switching to the ironically named Freedom Mobile (I have unrelated issues with their service), I also got a new phone running Oreo (8.0.0).

As I was compiling data for this email I realised that my problems didn't actually start with Freedom Mobile, as I have had two different phones with them in the almost three months I have been with them. For the first two months I had a Motorola E5 Play, bought unlocked from Best Buy. I then gave that phone to my wife and bought a Motorola G6 Play from Freedom. She now uses the E5, and as far as data is concerned only very occasionally uses the Web and no email at all, so she is not a factor in my tale of woe.

But since switching to the G6 my data usage has absolutely gone through the roof, by more than ten times. It may not be much data as far as some power users are concerned, but for me it's massive, and I want to get back below the 250 MB per month included in my plan. This is what my usage has been this year:

January: 56 MB (Ting)

February: 42 MB (Freedom, E5)

March: 35 MB (Freedom, E5)

April: 659 MB (Freedom, G6)

May (so far): 433 MB (Freedom, G6)

(The month is the date of my bill for the previous month.)

When I leave a location with wi-fi, and look at my data usage, I can use 20 MB within five minutes -- that's five literal minutes -- and I will have downloaded absolutely nothing!

I have checked the data usage of all my apps and it is my email app that is chewing through mobile data. It's the same app (K-9) I have used for over two years on all three of the phones I have noted above, and it blasts through data on my latest phone even when it is not actually downloading anything. I know that an email check with no new email still uses a few bytes, but not dozens of MEGAbytes! Even if I'm checking every few minutes, 288 checks a day (every five minutes) is not going to use hundreds of megabytes.

Given everything I have noted above, does anyone have any idea why a Motorola G6 Play phone would be using massive amounts of data/bandwidth? It doesn't seem reasonable to assume it's the email app, considering it's the same version of the same app I've used on previous phones where this behaviour was not evident, but I also can't believe that the hardware would make a difference. However, on the face of it that is the only thing that has changed.

How to make wifi list show duplicate SSID when different mac address

问:
Disable automatic system updates in Android One?
Is there some hack which I can use to disable automatic check and installation of system updates on an Android One device? I have my device rooted and the automatic installation attempt breaks my Magisk > Restore images functionality as the partitions are locked for editing when the system_updater puts it to use. And then does not leave them free until reboot.

The developer options do have a setting regarding "Automatic System Updates". I did diable it, but all it stops is the Automatic application of the update when I reboot. That is, it does check for the updates, it does the verification and installation and then asks me to reboot. The only difference the toggle makes is that the device does not automatically change to the new slot when I reboot normally.

I am looking for something which can help me in postponing the check for updates until I manually tap on it. If that is too much, at least the update should not download and install without my permission. Google seems to be copying the annoying Windows 10 kind of update process for Android One now.

Odin Flash error: SW REV CHECK FAIL : [lk]Fused 2 > Binary 1
I've been trying to flash stock ROM on my Samsung J7 Max. Briefly, these are the steps I followed :

Enable Developer Options

Disable OEM lock

Reboot phone and open into Download Mode (Power+Home+Down)

Open Odin 3.12 on PC (with latest samsung drivers installed)

Connect phone via original data cable

Load the four *.tar.md5 files into respective slots (BL,AP,CP,CSC taken from here)

Until now the message at top in Download Mode is:

```<code>    ODIN MODE (HIGH SPEED)
    PRODUCT NAME: SM-G615F
    CURRENT BINARY: Custom
    SYSTEM STATUS: OFFICIAL
    FRP LOCK: OFF
    OEM LOCK: OFF
    WARRANTY VOID: 0x1 (0x30d)
    MTK SECURE BOOT: ENABLE
    AP SWREV: B2 K0 S0
    SECURE DOWNLOAD: ENABLE
</code>```

Disable Auto-reboot and Click Start. The process runs for about two minutes and then following two errors occur-

On the phone: this line is printed-

```<code>    SW REV CHECK FAIL : [lk]Fused 2 > Binary 1
</code>```

On Odin: Here's the complete log:

```<code><ID:0/004> Removed!!

</code>```

Note that this same error happens if I try to upload a random tar file. So it seems an invalid BL file is causing the issue, but I've re-downloaded and verified the md5 hash of the BL file.

Also, I cannot open the recovery mode. Even when FRP Lock is off, the phone is showing a screen similar like this:

The message at the top on this screen says Rollback version is not matched (md1rom). Can anyone explain what this error is?

Before flashing, my phone had Android 8.1 and the firmware was also last updated on 21 Mar 2019 (Android version:  8.1, code: G615FXXU2BSC1).

Edit :
I've also tried to upload individual tar.md5 files to device and found that files other than BL file upload successfully and the above error is generated when I try just the BL file.

Upon pulling the slider to 1, the System UI crash immediately and only show black screen and everything stopped working. I am desperate now and really need kind people here to help me troubleshoot this to reset and get System UI working again. I will list down some background and information below.

Device:
Asus Zenfone Max Pro M2
Just updated to Android Pie today

What is working now:
- Power Menu
- Safe Mode
- Google Assistant
- Stock Recovery
- Fastboot

What is not working (Can't find a way to make it work):
- System UI
- ADB (USB debugging was turned on but I cannot authorize my phone without System UI)
- Unlocking the screen
- Boot loader not unlocked
- Internet (Data was not on before crash and WiFi require me to sign in)

What have I tried:
- Turn it off and on
- Boot into Safe Mode
- Wipe Cache in Recovery
- Flashing the same firmware again with recovery

Kindly request if you need more information.

Of course, the last resort is to do a factor system reset but I really wish I can keep my precious stuff in my phone... and also I've set up my phone to act as 2 factor authentication for my Google Accounts which I might be a problem if I reset my phone.

Thanks In Advance!

How to enable usb debugging on bootloop phone(Lenovo tab yoga 8)?

But after entering facebook.com, I don't get website of xx.yy.zz.aa instead I get genuine one. I have tried all the previous answers but it doesn't work, surprisingly what works is when I put 127.0.0.1 i.e localhost instead of any other websites in place of ip. Then it routes to localhost.

Is there any way to achieve this, if not in chrome any other browser. Or is there any way to disable global DNS and use local DNS only.

Help appreciated very much.

VPN not working on Android when on Wifi Network
I have a Synology NAS server that has a L2TP/IPSec PSK VPN Server running. I used to connect to it with my Android phone (Version 7) (and previously with my iPhone) just fine. Whether I was on 4G or on a Wifi, it always connected without problems.

I have recently replaced my Android phone with a new one (Huawei P30 Pro) that runs on Android 9. The strange thing here is, that I can connect to the VPN when I am on a 4G network, but when I try to connect to the VPN when I am on a Wifi connection, it does not work and comes back with an unsuccessful message.

I am pretty confident that it is not the Wifi network, as I can still connect to the VPN with my old phone side-by-side, but the new one is not working.

Is there any way to troubleshoot the VPN connection to figure out where the problem is? Is there any log files I can check on the phone? Or do you have any hints why that could be?

Thanks for any hints.

Why am I still receiving old—and resolved—Amber alerts on my Android phone?
For the past 2 months, every few days to a week, I've been getting an Amber alert. Oddly, though, it's the same one every time.

The notification reads as follows

Messages 3/13/19

Emergency Alerts

AMBER Alert: Paradise- 86 Camo F-250 MI/DQQ5813.  Suspect is white male.  Check local media.

Yeah, I just got that today, May 3, 2019.

Besides being utterly confused at the formatting, and being too far away to do anything, The alert is just plain old.

I looked up the license plate and the missing child and the abducters were found March 14th.

A Google search trying to figure out why this alert is broken only rendered instructions on how to turn Amber alerts off. I don't want to do that. I do not want to disable Amber alerts, I just want my Amber alerts to be correct.

I am using a different SMS app than the default (Silence) , and maybe that has something to do with it? But I doubt it. However, when I go to click on the notification, it tries to open up my old app. I don't want it to do so because I hate dumping my messages back and forth between the two apps.

I am concerned that the old message is displaying whenever I get a new emergency message, and therefore I can’t see the new messages. What might be causing this and how might I be able to fix it?

Permission denied on android directories?
Forgive my newness...  I've installed Android Studio/Android SDK in Windows 7, enabled debugging on my Droid Turbo 2 with Android 7.0, system version 25.216.2.kinzie_verizon.verizon.en.US, and successfully attached my device.  I've successfully made a backup (haven't tried restoring it), but of course it's a compressed file.  So now I want to browse my phone's directory structure.  So I opened a shell and tried to navigate around with ls and cd, but I see a lot of directories are giving me Permission denied.

Is there anything I can do about this?

Edited to add:  I was particularly interested in having a non-cloud method of backing up my contacts, sms history, and call history.  Normally, I periodically connect the phone to my PC via USB and just copy everything in Windows Explorer.  But, as I discovered when I moved to another phone yesterday that already had some of my contacts on it, the contacts file is not accessible to this method of backing up.  Verizon made a hodgpodge out of old and new contacts information which is going to take me another hour or two to sort through.  It would have been easier if I could have just restored this file.

I'd rather not root my phone if I don't have to, and from everything I've read, there is no root discovered for the Droid Turbo 2 anyway.


问:
Is there an easy way to transfer files between PCs and a phone via WiFi?
I'm currently using SFTP to send files between my phone and my Linux PCs, with OpenSSH server on the PCs and Ghost Commander on the phone. What is inconvenient is that I have to either type the password each time (on screen keyboard!), store it on the phone, or try to setup authorized_keys (which I'm hesitant to do for a mobile device, since it lets it do anything, not only send files). Using something like an FTP server without authorization is not an option: I don't want to get files from everyone around without a means to reject a transfer.

I'd like to be able to simply "offer" to send a file to the PC and, when the PC accepts this offer (the user clicks "Yes"), do the transfer; similarly in backwards direction — much like Bluetooth file transfers work.

Is there any software (zero-cost and ad-free) offering such functionality?

Bricked the phone by wiping every partition in TWRP
My Redmi 5 plus won't boot as I messed up everything while trying to flash a couple of ROMs. At first the two ROMs that I flashed were working well. But after some time, whatever ROM I flashed, the phone started to restart while setting up the first boot (choosing language, region, etc.) and no further. So I tried wiping every partition there is under the TWRP wipe section (cache, system, vendor, data, internal storage, and so forth). Then flashed a custom ROM again with and without GApps but no success. I noticed that the phone even started to restart before the first boot finished. Also, after flashing stock ROM, TWRP said no OS installed. I even tried flashing stock MIUI ROM in fastboot mode. Although it went well, still bootloop and the device keeps restarting. However, before all of these problems, I did take a backup of every partition, leaving nothing behind, so I restored everything but again the "No OS installed, are you sure to boot?" message. Now I'm freaking out, not knowing what to do. I read somewhere that flashing via QPST tool may help but I'm having problems with installing it.

If I manage to make my phone work again, I will not flash any other
  ROM, ever.


问:
App to send commands over telnet?
I have a home appliance which I would like to control over TCP/IP - telnet - protocol. Do I need to design and program my own app for that or is there a shorter way to success? Some "universal remote control" with controls and buttons that I could bind to specific telnet commands to a pre-configured IP address?

I have some generic Android on the phone (it should work on my Android 9 and any number of versions that other household members have) and on the other side is an AV receiver with some proprietary software that understands commands sent over telnet (no SSH on that one). Since it's all on the home network, security is of a lesser concern.

Sometimes Widget not working
(Using Google Translator)

There is a phenomenon that the widget can not run under certain circumstances. Even Preview is invisible.

At first, it occurred at the terminal of Galaxy S9 or more, and now it happens irregularly. I've been wondering if it's a version issue, but it works fine on my phone and other test phones. It does not seem to be a version issue.

If you have any experience or have a solution, please help me.

Mobile video player in Chrome doesn't work on certain site
I have a problem with build-in video player in Chrome.
For such sites, as  m.youtube.com  it's work correctly and looks like this:

It worked for site yummyanime.club as too.
But some days ago video player suddenly stopped working on this site in Chrome and other browsers. Instead, the video is played in the same player as on the computer (although I use a mobile version of the site). It looks like this:

Player stopped working only on this site.

It is inconvenient player on my phone. I want to use a player like in the first screenshot. I was surprised when I opened this site on my other old phone, and there this mobile player works:

In short, the problem is this: the mobile video player suddenly stopped working on a certain site on my new phone. This is a problem for all browsers. But on my old phone, everything works fine.

About system in old(correctly work) and new phone(have bug) accordingly:

So, main question is how to fix this problem and enable mobile video player on my new phone? But I will be grateful for any information about this: how this mobile player work, does it have any settings, related links and so on.

I have a new phone, and the icons in the quick settings are ugly in my opinion.

Can I change the icons used here easily, and if so how? (I see similar icons in the normal settings, i am happy if those change as well).

TWRP only allows flashing into either the Boot or Recovery partitions
I'm trying to flash a Pixel Experience GSI onto my 2017 Samsung (SM-J730G) using TWRP. In order to do so, I need to flash the GSI's system.img into my device's System partition. However, my TWRP only allowed me to flash into either the Boot or Recovery partitions. The other options I see in other phones (System, Vendor, Preload, etc.) are nowhere to be found.

Is it possible to play .3gp videos in browser on Android?

Chrome plays the video without image, only sound. And Firefox asks me directly to download the video.

I wonder if there is a way I can watch the video first in the browser, like a .mp4 video. Is it possible?


问:
Why does my Samsung Galaxy S8 Active no longer "Fast-Charge"?
I bought a refurbished Samsung Galaxy S8 Active in excellent condition about 6 months ago, and it came with the standard manufacturer-provided power adapter and cable for charging (Model: EP-TA20JBE, labeled "Adaptive Fast Charging"). For the first 5 months it charged without problems - Fast Charging was available virtually every time I plugged in the phone and my battery typically charged from less than 20 to 100% in about 90 minutes.

In just the last few weeks though, charge speed seems to have diminished significantly, and my phone never indicates Fast Charging anymore after being plugged in, only Slow Charging, which variably estimates 4-6 hours to reach 100% from less than 20%. I've used the same cable and adapter the entire time and haven't adjusted any software settings. It seems as if this original cable and/or adapter have simply crapped out, for no apparent reason. Occasionally, I'll plug in my phone before falling asleep at night, Slow Charging is shown, but when I wake up 6 or 7 hours later the battery has gained only 1 or 2% charge (or sometimes none at all) even though the cable remains plugged in and the icon still indicates that the phone is charging.

I did a bit of forum searching on other sites and learned that the manufacturer-provided cables and/or adapters can age very quickly or otherwise be unreliable. I bought a new cable and adapter of the same type, but made by a third party, and tested it: no luck. Neither the replacement cable nor the adapter, together or in combination with either the original cable or adapter, seems to improve the charging speed.

I'm still committed to the notion that the problem lies with the cable or the adapter rather than the battery itself, since I've noticed nothing unusual about the battery's lifespan or other activity in any way - there's no excess heat either when plugged in or not; battery life is nearly as long as it was 6 months ago when I first bought the phone; I never use the phone for any games or movies or other battery-intensive apps, just Internet browsing and basic communications. Observing the circumstances as empirically as I can manage, charging speed seems to be the only difficulty. But I'm at a loss to explain why.

Should I trust the perception that the cable/adapter combination is at fault? Is it preferable to purchase a cable or adapter from Samsung that is identical to the one I'm using now, rather than one of the many third-party options? How can I regain Fast Charging ability - or, at the very least, the peace of mind to know that when I fall asleep, I'll wake up to a fully charged phone? I appreciate any insight you can provide!


问:
Salvage app cache when unable to open app
Every time my phone reboots and sometimes even without reboot when it's working at I guess full capacity, it resets its settings and acts like I just booted the phone for the first time except from all the apps I've installed (i.e. non system apps) still being installed. However, I cannot open any non-preinstalled app as they just close immediately when I open them. Deleting the cache and/or force stopping the app doesn't help.

Since my last WhatsApp backup file msgstore.db.crypt12 is a couple days old, I tried to "rescue" the WhatsApp cache since the msgstore.db is just a backup file and WhatsApp stores the messages "live" in a different database that doesn't seem to be accessible without root (and I cannot root my phone at the moment).

The WhatsApp app-info shows that WhatsApp actually still occupies a lot of cache data and app data and the WhatsApp symbol on my application overview still shows the number of unread messages I had before the last unwanted reset.

I already tried backing up the whole app with as much app data as possible via adb with adb backup C:\wabackup.ab -apk -obb -shared com.whatsapp, uninstalling WhatsApp, reinstalling it and then restoring the backup but running the app afterwards just prompts me with the screen I would usually get when running the app for the first time after the installation.

The WhatsApp folder seems to be totally fine but maybe it's a permission issue with the folder. ( How to manually transfer entire Whatsapp installation to another device (the hard way) )

I would really like to fix this, not only for WhatsApp but also for other more important apps like banking-apps and 2-factor-authentication-apps that of course encounter the same problem at the moment but unfortunately I am not too familiar with the way Android stores app data.

This is pretty annoying obviously and I have already ordered a new phone. I am currently using the SM-J510FN.

问:
Frequent contacts disappeared
I have a Moto G5 with Android 7.0 and Phone 3.00.00.

It used to be the case that when I called one of my contacts, they would appear in the "Speed dial" tab of the phone app, just after my favorite contacts.  For some reason, my phone app's speed dial tab doesn't show any frequent contacts any more.  Only favorite contacts appear.  The call history tab still shows these calls, so I am using that for now.

Do NOT ask me to look for a "Show frequently contacted" setting.  I have checked both the phone app's settings and the contact app's settings and I don't see a setting for "Show frequently contacted" which seems to be a Samsung setting.

I don't receive text messages on time
Using a Samsung Galaxy S7,

When someone send me a text message (sms), I often receive it several tens of minutes late, sometimes even a few hours late.

For instance:

```<code>Other: - We're going to the cinema tonight, wanna join?*
Other: - Come on join us!
Me: - Where?
</code>```

*For instance I receive this message 1 hours later so this is kinda annoying.

I first suspected a contact failure of my sim card but it doesn't seem to me that this is the case
