Recovery can't mount system, cache, data, can't install anything
My internal partitions seem to be screwed up for some reason. Phone is a Zenfone 5. I'm not really sure how it got here but I wiped system, dalvik, cache, data, internal storage before so phone is completely empty. TWRP fails to mount /system, /cache, and /data and now I can't install any ROM, not even stock firmware. Sideloading also doesn't work.

Here is the log from TWRP when I try to install a new ROM.

Does clearing the cache only clear your cache on a multi-user device?
I share a spare phone with my other half. I have just come to install an app on it and been unable to, due to lack of space. Looking in Storage I can see 400MB of Cached data but when I attempt to clear it, nothing happens.

I presume that these 400MB are being taken up by cached data in her user account rather than mine, thus I cannot clear it.

Is there anything I can do to clear up this device without waiting for her to come home and do the tidy up herself?

Is there a secondary way to check whether I have voicemail if the phone application is not registering correctly?
After the August Marshmallow Android OS update, I realized I had unheard voicemail messages. These messages had neither shown up as notifications on my phone nor appeared under the visual voicemail tab of the phone application prior to the update, and I think they extend back to my last Android OS update (roughly one month ago). Obviously, it is a problem if the phone application does not register that there are voicemail messages. </p>

<p>Is there a secondary way to check whether I have voicemail? I would strongly prefer a method that does not require manually dialing into my voicemail to check. </p>

Returning S3 to stock - What bad can happen?
Its been a while ( 3 and a half years, in fact) Since I last returned a device to stock. Shamefully, I don't remember the process (I do remember that PC kies is the enemy, however.)

LG Volt (Virgin Mobile) Stuck in Bootloop
So I've been trying unsuccessfully for a number of hours to fix my brother's phone. It's a Virgin Mobile LG Volt. It's not rooted.

He was complaining of it freezing and not responding. I told him to just take the battery out and restart it which has always worked before. He did this several times apparently and it is now stuck in the LG/Virgin Mobile animation loop.

He said it wasn't updating and he hadn't uninstalled or installed any new apps from the play store. The only thing he said he could think of that he'd done was he had cleared the data from Google Play Services which I don't think would have caused this problem?

I've tried taking the battery out. I even let it die at one point. I tried unsuccessfully to get it to reboot into safe mode. I finally managed to get it into recovery mode and cleared the cache and rebooted it from there. No luck. I finally gave up and factory reset it from the recovery menu. It's still stuck in the loop.

Any ideas on what I can do, short of telling him to just get a new phone?

SD card does not appear as adoptable
I have a Samsung Galaxy On5 that has been rooted, and I want to adopt my SD card as internal storage. I am attempting to adopt the SD card using ADB. The process for this is well documented, but every guide I have found assumes that the SD card is listed following the command sm list-disks adoptable. My SD card is listed after using the command sm list-disks, but not after using sm list-disks adoptable. The card has been freshly formatted, and contains no data. Is there any reason why my sd card might not be adoptable?

Problem with creating an ext3 partition on SD card
I'm trying to partition my SD card with a ~31gb FAT32 partition and a 1024mb ext3 partition for A2SD. I've tried making the partitions with CMW-Alpharev Recovery v2.5.1.8 and with gParted (on a bootable live USB stick) and neither works. Basically, whenever I try to create a second partition on the card, the second (or later) partition doesn't work anywhere. It's not recognized by my phone, Windows or gParted (even right after parttitioning). The first partition does work, though. So if the ext3 is first, the FAT32 doesn't work and vice versa.

I have no clue as to what could be causing this or how to fix it, any suggestions?


问:
What part of Android is responsible for reporting how much battery an app uses?
In Android Marshmallow (and maybe earlier versions), you can go to App Info and see how much battery an app has used. If you click into it, it shows much how much CPU it's used as well as keep awake and network usage. The last line on the view shows "Computed power usage".

What part of the OS calculates this power usage? If "Computed power usage" is coming up as 0-1mAh regardless of usage, where would a developer go to fix it?

问:
What "password" am I being prompted for before a wipe?
I have a Samsung Galaxy S7 with Verizon. I've also had my phone wiped 4 times because of our corporate policy requiring a device wipe after 4 or 5 attempts and, when hiking with my phone in my pocket, somehow triggering invalid fingerprint login attempts (my hands when hiking and climbing are definitely not in my pockets).

But my question here is what "password" I'm being prompted for right before my phone is wiped. It just says, "Please enter your password" (or something equally vague) and gives me an alphanumeric keyboard. In the past, I've tried my Google account password (tied to the phone) and even my PIN. This last time, I meticulously made sure I entered my Google account and the phone was wiped right before my summit bid (I was going to snap a photo and ended up loosing a few to date; the worst is when I lost some climbing route beta and we got off-route).

Here's my set up:

I have a PIN set up (required by policy).

I have fingerprints set up.

I do not have a lock screen password (could this be it? Samsung said I should be prompted for one but support doesn't seem to understand what I'm asking about anyway).

My Google account uses 2FA, so in most cases my raw Google password won't suffice. Do I need to generate an app password?

The phone is stock (i.e. not rooted and only apps from Google Play). The vague "password" screen looks the same as my lock screen PIN screen (i.e. alpha-blended with same font).

For now, I'm not planning on rejoining it to our corporate network but may want to in the future. I've also ordered a cover for when I'm hiking or climbing to hopefully avoid this situation (it's only ever happened in these situations). But should I be prompted again for this "password", I want to know what I'm supposed to enter before loosing everything and spending hours resetting up 2FAs for various sites, apps, etc. (the backups never seen to restore everything, but, then again, I'm usually trying to restore while on the fringe of network connectivity).

问:
Why are apps excluded from Titanium Backup?
I have been using CM Browser for couple of years. A couple of months ago I set Titanium Backup ( Pro - version 7.5.0) to backup on schedule as shown below ( 3 as maximum backup versions ):

After the last update of CM Browser, which I didn't like, I uninstalled it, being sure I could switch to the earlier version. Surprisingly, I didn't find CM Browser backup !

To doubly verify, I installed CM again and took a manual backup (by force-running the schedule) and sure enough it didn't show up – despite of the "backup completed" toast being shown (no error message in between either). And yes, I've verified that I didn't have any filters set that might be hiding it.

It can't be a version issue of Titanium as the previous version should have retained 3 backups.

Why is this so? What makes apps "unbackable" ? How do I fix this?

Device: Moto X Play, 6.0.1, stock, rooted

Edit:

As suggested by Izzy in comments, searched the backup directory and found backups of Browser. Installing the apk from there got me my old Browser version but minus the bookmarks ( Data for apkalways included in preferences).Backup of newer version also present in apk

Mailed the developer. Will post updates but meanwhile ideas to troubleshoot are welcome

Edit 2: when I took a logcat for the second time (in the process of installing app and forcing a backup), TiBu mysteriously decided to show me CM Browser with all previous versions and data intact. I haven't the faintest idea and will post an answer if the developer clarifies. I have mailed him the logcat. Pastebin here

App update downloads but successful update doesn't show in notification bar
This thing happened to my LG G4 (Android 6.0) 2 times in the last month.

I have google play store updates on manual so once every week I manually update the apps myself. Some updates are successful but for other apps the update is downloaded, tries to update but the app doesn't appear as successfully updated at the notification bar at the top of the screen (usually it says that the apps 1,2,3 and 4 were successfully updated). No error is being displayed either.

The first time this happened (Viber app didn't properly update), the phone could not start after restart and stuck at LG logo. I had to factory reset it to make it work again.

The second time, I saw that a specific app (this time it was the android webView system app) didn't update properly so from google play store I removed it and then reinstalled it and everything went fine.

Does anybody know what is going on, why does this happen and how to stop this from happening?


问:
Automatic Do Not Disturb rules for calendar events do not work with imported calendar
Update: I've updated the question, check the bottom of this post for the details I've found so far and the last problems standing in my way

The problem

My work schedule is provided to me as an online iCal file, which I have imported into Google Calendar. This way all events are visible in my Google Calendar. I'm attempting to set up my phone to switch into do-not-disturb mode when I'm at work. This is a feature that has been added in Android 6.0.

Android 6 added a neat feature to switch to Do not Disturb mode during calendar events. I managed to get this working using my default Google calendar. However, the imported events from the external iCal URL don't seem to get picked up: only events I manually add to Google Calendar turn my phone into do-not-disturb.

Time-based rules work perfectly so the feature itself is not broken.

My current settings are as follows:

Rule name: work
During events for: my.email.address@gmail.com
(into which I've imported the iCal URL)

Where reply is: Yes, Maybe or Not replied

Do not disturb: Total silence

What I've tried:

Add the iCal URL to a different Google account

Add the iCal URL to the Outlook app and select that account in the automatic DND settings

Modify the iCal (using a PHP script) to add the RSVP status to every event (every event now says it has been accepted)

My phone details

Device: Oneplus One

Software: CyanogenMod 13 (the latest nightly)

Root: available if necessary

I know my way around ADB and the Linux shell if I need to modify my system files. I know apps are available to do the same thing Android is supposed to do, but I prefer not installing an extra app.

Update #1

I found the Java file which handles these events. It seems like the problems lies with line 124: getPrimaryCalendars.
The code seems to only accept events from primary calendar. Imported calendars are not used as primary calendars though...

Update #2

Okay, so the list of requirements for the Do not Disturb event detection to work seems to be as follows:

The current time must be greater than the beginning of the event and the current time must be less than the end of the event

The calendar the event is in must be

Visible

Primary

The event availability field must NOT be "free" (so it should be marked as AVAILABILITY_BUSY, AVAILABILITY_TENTATIVE or something else, as long as it's not AVAILABILITY_FREE)

It should meet the attendee requirements: the event has an attendee with the same email address as the "calendar owner". This means an attendee value needs to be set for in the iCal file, containing the email address of the Google account the iCal file was imported into.

The "reply" field must be equal to the option the user selected. This means the attendee status must be ATTENDEE_STATUS_ACCEPTED if the user requests to only activate the rule when an event has been accepted, ATTENDEE_STATUS_ACCEPTED or ATTENDEE_STATUS_TENTATIVE for "yes or maybe" or anything but ATTENDEE_STATUS_DECLINED when the user selects "yes, maybe or not replied".

Does anybody know how to pass an imported calendar through this filter? Or how to make a calendar "primary" so the check can succeed?

Mount (physical) SD card on Linux
Soaked my phone (Moto G2, Marshmallow) and it died completely. I took out the micro SD card and unsuccessfully tried to mount it on my Debian system.

The SD card is recognized and I can see 2 partitions:

```<code>Device                                       Start                   End               Sectors                Size Type

</code>```

However, I can't mount either one. I tried this way:

root@laptop:~# /bin/mount -t vfat /dev/mmcblk0p2 /mnt

Syslog contains the following:

```<code>[ 5880.536862] FAT-fs (mmcblk0p2): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
[ 5880.537346] FAT-fs (mmcblk0p2): invalid media value (0x10)
[ 5880.537349] FAT-fs (mmcblk0p2): Can't find a valid FAT filesystem
</code>```

Q1: Is it possible that the sdcard is encrypted? If so, how could I verify this?

Q2: I have another Moto G2 with exactly the same model number (i.e. HW specs). Is there any way to restore the data on the card? (I know, this would defeat the purpose of encryption)...

DLNA app that supports output orientation?
On the Samsung Galaxy S2 is a DLNA client / server application called AllShare.

This can direct audio, video and images to a DLNA consumer on the network the phone is on.

In my case, this happens to be a Samsung TV.  This works automatically, I push out a video or image to the TV, and it appears (without doing anything to the TV, very cool).

The only hitch is the video and image orientation isn't taken into consideration, so all images and video appear in a single orientation (landscape), regardless of the orientation they were captured in.

Does anyone know if there is a way to get the TV to recognise the orientation, or get the S2 to orient what it sends to the TV?

Perhaps there is a DLNA app that can support on the fly rotation?

Google Play Services - taking up over 2GB and random crashing
I have already looked for an answer to this like thus:

https://stackoverflow.com/search?q=%22google+play+services%22  and

https://android.stackexchange.com/search?q=%22google+play+services%22

This question seems to be the same, with no answer:  Google Play Services takes up all internal storage

Recently, my Android (Galaxy S4, 16GB, Android 4.4.2), decided that Google Play Services needed to take up 1.5GB. I figured that it had somehow run amok. I followed instructions to delete the data. That seemed to be good for a while.

Well, just a week or so later, it downloaded 2GB+ (over the mobile data connection, eating up more than my monthly allocation). It is now 2.3GB. I suspect that it would take more, but the phone is saying it is out of space.

So, deleting the data didn't work.
I can't uninstall Google Play Services; I can try to tell it to revert, but it can't because the package is an active device administrator. But, it doesn't show up in the device administrator settings list.

I've looked in the folder, and it looks like it has an email file and an email log. These are 500MB+ each.

Every now and then, Google Play Services (and sometimes "Settings") will crash.

Can I fix this? Can I at least stop it? If I can't stop it, can I tell it to only use Wifi and not mobile data?

Cannot SIM unlock Samsung Galaxy S7 with Rogers (Canada)
My dad got the Samsung Galaxy S7 back in May and wanted to SIM unlock it shortly after because he travels a lot due to work. No rooting, just unlocking the phone to use with foreign carriers. At the time, he went to a local store that provided him with a code but it wouldn't work, they told him something along the lines of "this phone is too new and cannot be unlocked yet". I was really busy at the time so I couldn't provide more assistance unfortunately. He phoned Rogers (his phone provider) and was told that they could provide him directly with an unlocking code but he had to wait 3 months from the time of the purchase. He thought that was a much safer way to do it, so he waited.

Fast forward to now, and the code he was given wouldn't work. According to him, even after following the steps in this page from Rogers he gets a message that says "INCORRECT NETWORK UNLOCK ENTERED". He also attempted to get it unlocked at a local store (from the foreign country he's currently working at) to no avail. I believe they even tried a factory reset, and the SIM unlock still wouldn't go through. As time goes by he is getting more frustrated and I don't know how to help since we're in different countries. Is the phone hardlocked after many unsuccessful attempts? Can such a thing occur even after a factory reset? Also, do you think it would be possible to get the phone sent to warranty for this problem?

What's the easiest way to switch multi-window apps?
I got the 7.0 Nougat upgrade yesterday, and loving the new Multi-Window support. However, I can't find a way to easily switch the positions of the two apps.

The quickest way I found to switch them was to do this:

Drag divider all the way up to close Multi-Window with the bottom app as the only app

Hold apps button to restart Multi-Window, putting the only app on top

Select latest app to put it on the bottom

Is there any hidden way to do this in a single step, like a long hold, triple tap, anything like that?

Simultaneous OTG + Charging Capability
I'm working on a hobby project to stick a tablet in a car to replace the factory head unit. For this, I need to connect the reverse camera to the tablet (via USB, using something like an EasyCAP adapter), while the tablet being charged.

So far, I found that Lava SimulCharge adapter claims to do this. Although it's very picky about the devices it works with. (Exclusively a few Samsung Galaxy tabs with strict OS versions and even cable lengths)

I would like to know what other alternatives I have which can do this. (Prefer not being locked down only to the LAVA supported tablets, as they're quite expensive for my purpose.)

Is it a Samsung only feature? (seems like most Windows tablets support this out of the box across a number of OEMs. But haven't seen any Android device that isn't Samsung supporting this.)

Can I check which tablets have the support?

I prefer to do this without rooting the device.

Firefox pops up when you clear downloads
I've ran into this problem for years. I download a bunch of pics in Firefox, and then have to manually clear the download list. When I do, Firefox is brought to the foreground.

This should not be the case, and I think it's a bug.

I can't find anything about this, possibly because the search terms are too common.

Are there fixes or mitigations for this behavior?

Currently running rooted on android 5.1 on Note 2, but this problem has occured on different devices and different versions of Android. I think 4.x and later. That's coincidental though, because Firefox only really got official about that same time.

Remove out of range networks on Android 6
Having issues removing 2 old out of range wifi networks on android 6 - Samsung Galaxy S5 - Corporate phone, therefore Looking for an UNROOTED option.

Resetting all network settings through "backup and reset" has no effect.

问:
Is there a way to increase usb power detection sensitivity?
I am looking for a way to have my phone register a usb power connection sooner or more reliably.

I need the phone to register a signal through the usb as soon as it reads any kind of power fluctuation if possible. I have two options for the power source: a constant power and a pulsating power source. I can get the device to register it with the constant power but it takes a while to work. So i need one of the following.

to reduce the time it registers the power.

to reduce the sensitivity and it triggers more easily.

to send power over the data wires instead of the power wires to make the device think its receiving a data signal. I would need to know how much power could be used across the data cables but I don't know if that is even possible.

Note: its not to use for data or powering the device. I just need it to act as a sort of relay to activate applications.

Also, I tried the pulsating power on my nexus 7 and it worked great but when i tried it on the device i wanted to use it with, it didn't detect the pulsating power. Maybe the Nexus device has more sensitive settings or perhaps it has a better capacitor etc.

Thanks in Advance

keep on getting "could not connect to device" on nexus 6p <--> mac
This used to work reliably for me all the time. Simply connecting my nexus 6p to my mac, tapping on the file transfers option in the USB for file transfer option and boom

It's not a big surprise.. I've always got that screen but simply restarting the phone or unplugging the USB and then replugging it worked (sometimes I had to turn off developer options for it to work).

But now none of these procedures work

What I do know

I know it's not a physical problem with the usb cable.. because I can access my phone using adb ssh just fine

I've also turned off my adb server just in case etc

Ideas?

问:
How to use mobile Internet on trains effectively?
When I'm on a train ride (mostly in Germany) I often find that this results in very poor mobile Internet connectivity on my Android devices.

Particularly, loading of even small web pages may take eons. I suspect that this is due to switching between mobile network cells while the train is in motion.

Even more annoyingly, this phenomenon can result in pages never finishing to load. Even though the device claims to still have mobile connection (albeit poor signal strength), the web browser gives up on loading pages over and over again.

In my opinion, this problem could be mitigated by setting a huge timeout value and/or caching partly retrieved pages on the device:

If I could set a really large timeout value for the web browser (Android browser, Chrome for Android or any other browser), the page would probably still take a long time to load, but at least, it would work out eventually, instead of aborting page load continuously.

If the browser (or some proxy server app on the device) would cache the parts of a web page it successfully retrieved and continue from there (using HTTP Range requests), it would be able to present the entire page eventually. (Similar to how a download manager works, except that it's for every web page.)

Is there any Android browser (or some kind of proxy app) that allows for setting appropriately large timeout values?

Alternatively, is there any Android app that allows for surfing the web in a "download manager" kind of way, picking up where it left off when the connection went bad?

Remapping Android hardware keys on CyanogenMod
What I'm really disappointed about Android is its multitasking. The recent apps list quickly gets cluttered with apps I won't use in any near future. I'd like to be able to quickly kill an app I know I won't need anymore today.

Examples:

home button kills the current activity (if any)

home button kills the current activity (if any) and triggers the recents. The recents works as usual - doesn't kill any app

double tapping the home button kills the current activity and triggers the recent, single tapping works as usual

How can I achieve it? I know about GravityBox but it's not supposed to be installed on non-AOSP phones (I'm running CyanogenMod in this case).

Direct audio to bluetooth headset only if answered on headset buttons
Is it possible to have the call audio redirected to the bluetooth headset only if the call is answered by using the buttons on the bluetooth headset.

That means that if I have lunch in the cafeteria located directly above my office the sound would not default to the headset at my desk, but in stead to the internal speaker of my phone - if answered by using the on screen button on the phone.

I know I can change the output by using the on screen buttons after answering the call - but were hoping to make an automatic selection based on the way the call is answered (button on headset / on screen button on the phone).

Third party apps or Tasker (or similar) script is an OK way to accomplish the task if needed.

Thanks in advance for all help given.

Preventing device wake up on USB
Is there a way of preventing an Android device from waking up/staying awake when a USB is device is plugged in?

I know Windows allows this in device manager. Is there a similar setting in Android or can I accomplish this via changing configuration over ADB/fastboot?

Actually, I'm using the LAVA SimulCharge adapter to connect power and a USB device. When the power is lost, I dont want android to stay awake.

UPDATE

Video to explain the issue
https://goo.gl/photos/FQxKmDRWKqxbwgPb6

Screen timeout set to 5 seconds to demonstrate.

Screen lock set to none (but same with swipe or PIN. Just will show the lock screen instead)

Pressing the power button turns off the screen momentarily, but wakes up almost immediately.

Sometimes After about 5 minutes of this, the EasyCAP light stops blinking and the screen turns off, but the device battery level drops about 10% per hour while its "asleep" unless the OTG adapter is removed.

Removing the power cable from the OTG adapter end (instead of the wall end as I did in the video) lets the tablet sleep properly.

Doze behaviour on Nougat (7.0.)
Doze behaviour has been changed in Nougat. Doze is implemented in two stages

When a device is on battery power, and the screen has been off for a certain time, the device enters Doze and applies the first subset of restrictions: It shuts off app network access, and defers jobs and syncs.

If the device is stationary for a certain time after entering Doze, the system applies the rest of the Doze restrictions to PowerManager.WakeLock, AlarmManager alarms, GPS, and Wi-Fi scans.

My question: What are the typical timings for step 1 and 2?

Even in Marshmallow , I could not find a reference to exact timing but was reportedly between 20 and 40 minutes.

I am wondering if timings have been specified now, though my search didn't yield anything

问:
Without telephony and GPS apps/libraries, security subsections crash?
In CyanogenMod 13, I've removed all telecom/telephony/GPS support from a ROM in an effort to reduce the device to basically be a wifi-only mini tablet. This entailed removing all relevant apps and a few libraries.

The ROM boots fine after removal, but lockscreen, security, and privacy aren't accessible in the settings; settings crashes when attempts are made to access any of them.

On previous versions of CyanogenMod on the same and another device this didn't happen, but then again I've updated the script I use to be more comprehensive as I discover new parts of the system that address telephony.

I've cross referenced the options in each settings subsection with the apps and libraries removed, and there seems to be zero crossover. Nothing in privacy, lockscreen, or security references GPS or telephony in any way.

I've done some tests to replace removed apps to try and do a process of elimination, but there are a lot of apps the script I use removes. I've only gotten through two or three of them so far, but none of them restored access. The obvious one seemed like it would be dialer.apk, but allowing that one did nothing.

Anyone know:

what telephony/GPS apps are required to run the aforementioned settings

what the reasoning is behind this counter-intuitive entanglement, and

how to maybe rebuild the ROM so that these apps and libs aren't required to access the full settings?

How can I create a keyboard shortcut for a phrase?
On Apple iOS, there is a section in the settings where you can assign a letter sequence ("shortcut") to any text you want.  When you type that letter sequence, the text you assigned to it shows up as the default replacement if you enter a space.  Of course, there is another "replacement" available which is the letter sequence itself so that you can still have that letter sequence in your typing.

EXAMPLE:
I assigned mmb to the address of my rented mailbox.  When I type mmb on my iPhone, my rented address is the default and replaces the "mmb" I typed if I tap the space key.  If I want it to say "mmb" then I have to tap the replacement option that has "mmb" in quotes.

In this way, I can send my rented mailbox address to anyone who needs it by typing mmb.  There are several other short letter sequences that I also use on my iPhone.  I'm switching to Android, so I'd really like this functionality on my Android.

I have a Samsung Galaxy 4 running Android 5.01.  Apparently, there is no longer a "personal dictionary."  I installed the "User Dictionary Manager" which allowed me to create a shortcut, but when I'm sending a message, the shortcut is ignored.

For example, opening up the side menu gets you a list that says:
Recent, Drive, Images, Video, Audio, Downloads

Its not totally clear where the files listed under each label are pulled from. The files listed are a history and thus often no longer exist. So I can click on Downloads and select FileThatNoLongerExists.txt. This will probably result in an application error.

I want to be able to:

Update the set of files listed through the SAF. Listing deleted files is stupid

Clear out files I do not want to be visible through the SAF. Most computer interfaces that have a "Recent Documents" list let you clear or disable it

How would I go about doing these things?

Headphones and earbuds not working properly on new HTC M10
I used an HTC M7 since it was released, never an issue of this kind.

Get the M10, which is overall great. It updated a few days ago to new firmware. But the following issues stand out:

Bose SoundTrue headphones: Only work if I plug them in part way (all but the last 1 mm). If I plug them in all the way, I hear nothing.

Skullcandy earbuds: Often have to re insert jack 1 or 2 times to get the mic to work.

Great phone.... but how to solve?

Something is eating up all my storage space and I don't know what it is
I'm using a 2014 Moto X, 32GB. Recently I've noticed very low free disk space and I'm not sure what is causing it. When I plug in the phone to my PC Windows Explorer shows 556MB free of 24.7GB at the time I'm posting this. But when I go into the phone's storage (in windows), highlight all the files and folders, then get the properties it shows that everything totals up to 2.79GB. Something's not right, the numbers just don't add up. I've also used Solid Explorer to try and figure out where this is coming from, but the numbers there also don't add up. It is showing 1.03GB free on internal memory, but when I look at the list of folders sorted by size (screenshots below) it doesn't add up.

Any ideas how I can figure out what files are taking up all this space on my phone? I can't even seem to find them.

Thanks!

In-app purchase (in my app) says: Google Play account not authenticated

My app has been previously tested with one single account and it worked. This version is not the same but nothing important has changed.

When I go to Google Play it seems that the account is already selected and working.

So what's the issue?

Samsung's equivalent to Fastboot's Temporary Flash
Questions that address Samsung not having fastboot can be found here and here.

My question:

With fastboot you are able to use fastboot boot boot.img to temporarily boot your phone with a custom kernel, and upon reboot use the stock kernel. Is there an alternate to the above command for Samsung phones. Because with Odin, it overwrites the current kernel, so if the custom kernel doesn't work your left with a soft-bricked phone and have to re-flash stock firmware losing all your data.

Is there a way to enforce a minimum WiFi quality level before switching from mobile networks?
My phone has access to various hotspot networks in the area I live in. When I walk down the street, now and again I pass by a hotspot and my phone will attempt to connect.

As often as not, the phone will connect, but for whatever reason, it will be a weak connection, and effectively my internet access stops. My phone abandons my cellular network connection in favour of the wifi, even though the wifi is bringing in little or no data.

Is there a way I can enforce a minimum standard of connectivity to a wifi network so that my phone won't leave my mobile connection in favour of hotspots that are useless?

What's missing to run Next Radio, and how can I get/install it?
I've got a Samsung Galaxy S4 (Verizon), currently running Lollipop as provided by the carrier -- not rooted.  Verizon has apparently recently begun to allow NextRadio to run on some of their phones, including the S7 and S7 Edge, but the app (which plays FM radio off the air) still reports something about required software missing when I try to install it.  I presume, at this point, that this is a missing driver or similar that would normally be supplied in an update from the provider, but of course Verizon is barely updating security on Lollipop and S4 platforms at this time.

Is there any way to get the required driver on my phone so I can use NextRadio or some other FM radio app?  Ideally without rooting the phone, but if rooting and updating to a newer Android version is required, a recommendation on rooting app or method would be appreciated as well.  If it matters, I run Kubuntu 14.04 on my computer, though I also have Kubuntu 16.04 installed; there's not a single Windows machine in my house.

Does Andriod have an event viewer and how do I access it?
I have a new Samsung S7 for 3 months now - My phone crashes in a big way around once a month, I mean I can't even do the factory reset because I cannot get to the recovery screen, no buttons are responsive so holding them to get to the recovery menu is useless, I have to wait till the battery dies before I can recharge it and switch it back on so I can carry out a factory reset before it will crash again (usually 20 minute time frame before it will crash again).

I barley have anything installed (as this is my 3rd time of factory resetting my phone it gets boring re-adding apps etc so only the essential apps are installed whatsapp, bbc news, stock apps)

I work in IT, if this happened on a server I would go view the event viewer to find out what exactly was the root cause, or at least a clue towards why, my question is do android phones have an event viewer hidden away or is there something that I can install that will capture information?

The phone is on the latest firmware & android version and has not been modified or tampered with in any way shape or form.

How to decrypt Cyanogenmod Updater zip files? (/sdcard/cmupdater)
I am using CyanogenMod 13 on my Oneplus 3, and I wonder how the cmupdater obfuscates/encrypts downloaded system update images.

To illustrate what I mean:

When I download "cm-13.0-20160908-NIGHTLY-oneplus3.zip" manually on my PC, it has the same SHA1 checksum as stated on the website. When I look at it with a HEX editor, it has the usual ZIP file header (starts with "PK").
I can flash this file without any problem manually in TWRP.

When I download the same update via Cyanogenmod's update tool, a file "cm-13.0-20160908-NIGHTLY-oneplus3.zip" will be created in "/sdcard/cmupdater/" (which seems to be equal to "/data/media/0/cmupdater/" and "/storage/emulated/0/cmupdater/"), but it has a different SHA1 checksum than stated on the website.
When I look at it with a HEX editor, it does NOT have the usual ZIP file header (does NOT start with "PK").
I cannot flash this with with TWRP (says "zip file corrupt"), but I CAN flash it when I select this file within the running Cyanogenmod session and select "update".

This is also valid for any other Cyanogenmod images, "cm-13.0-20160908-NIGHTLY-oneplus3.zip" is just an example.

How can I decrypt/unobfuscate the files in "/sdcard/cmupdater/", so that I get the original ZIP file? (Which can be flashed with TWRP)

Why I am asking this: I have a file "cm-13.0-20160731-NIGHTLY-oneplus3.zip" in "/sdcard/cmupdater/", which I would like to decrypt.

The original file is not available anymore at the CyanogenMod mirror, they don't store older releases (which is a very, very bad thing).
All current nightly/snapshot CyanogenMod builds don't work reliably on my Oneplus 3.


问:
How can you force an app to display it's portrait view while the device is physically in landscape orientation?
Ok, please read what I am saying BEFORE you go telling me to download a myriad of screen orientation locking apps...

I have an app (Innomail) that uses 2 different displays one for portrait and one for landscape.  I do not like the landscape view.  What I want is when I turn my device to the landscape orientation physically is a way to force the app to rotate so it fills the landscape screen BUT I want the content and screen elements to display as they would if the device and app were in portrait mode.  Basically when in landscape mode Innomail gives you a split window with folder list on the left.  In Portrait on the other hand you ONLY see your email on screen and have to swipe from the left to see this folder list.  I DO NOT like this sidebar and do not want to see it in landscape.  I do want the app to rotate to fill the screen in landscape, but I want the portrait view of the app where I would have to swipe from the left to see this menu bar.

I have searched numerous different ways and looked at many many different pages, but the only solutions are to decompile, edit the manifest or code and then rebuild the app.  This is insane.  There should be a way to tell the OS I want you to rotate the screen, but I only want you to draw the screen using the portrait view.

SD writing capable SSH server for Android Marshmallow (6.0.1)
Is there any SSH Server for android (similar to SSHelper or SSH Droid) that will allow me to write to the (external) SD card without having to root my tablet?

Can I display a person's full name for SMS in Google Hangouts?
For the Google Hangouts app, it appears that SMS messages (as opposed to actual Hangouts messages, which I'm sure would behave differently) only display a person's first name under an SMS received from them.  This is normally fine, but is confusing when you're in a group text with, say, a fella named "Bob Jones" and another fella names "Bob Smith".

The Google Hangouts phone notifications are specific when you first receive the SMS, but when scrolling through the messages in app I will simply see all messages being received from "Bob", with no way to disambiguate. I could view message details and look at the "From" phone number and see which Bob in my contacts has that number, but we all know that's not going to happen.

An ideal option for me would be to have Google Hangouts display a person's full name under each SMS.  Unfortunately I looked through the app's own settings menu, but could find no such option.

Has anyone else solved this problem?

Things I've considered:

I thought about concatenating both peoples' names (i.e. "BobJones" and "BobSmith") but when I use a voice command to call someone, my concern is that the voice command wouldn't quite work with such weird pronunciations, especially considering I'm not actually working with names as simple as Bob, Jones, and Smith.

Why does Android GMail app pop an icon for new mail when I delete a message in web GMail?
I have my GMail Android app set to notify on new messages.

However, it ALSO pops up notifications when I simply delete an existing (new or read) message from the web-based gmail.com

Is there an explanation of why this happens and how to stop it?

I saw a related question on A.SE -  Gmail notification sound only for new mail - but it was for notifications when marking messages as unread or moving the messages into Inbox.

Also, it wasn't answered and the only helpful comment wasn't something I can use (Turn on "Notify Once" setting) since this would ALSO stop per-new-message individual notifications which I need to have.

UPDATE: If it matters: Droid X, rooted stock Froyo 2.2. Gmail - latest version but this behavior was the same for the last year, with all versions of the app (likely since day 1, I just didn't use gmail on the web back then too frequently).

Significant latency with touch/stylus tracking when using notetaking/sketch apps?
I am using a Adonit Jot Pro stylus for sketching and hand writing notes. On my Nexus 5X and even more so on my iPad Air (2013 or 2014), the responsiveness to the stylus is acceptable and/or great.

On my Android tablet (Project Tango Yellowstone dev kit, specs below) the lag is so significant that when trying to sign my name at normal speed in cursive, the last few characters look like a low amplitude sine wave. It's as if the stylus contact gets so far ahead that whatever interpolation code used to draw is sampling at a very low rate or the contact gets so far to the right of the current 'drawing position' that it just flattens out the letters.

Comparing the Nexus 5X with the tablet via Google Keep hand written notes, the phone is much more responsive. On the iPad Air, the responsiveness is excellent.

So what determines this latency and is there a way to address it?

Undoing "Use network as is" for wifi connection on secured network
First of all, I am not a device expert at all! So I'll do my best to describe what's going on but I don't know all the fancy words and labels to these things... Sorry.

Recently I was having trouble with the wifi connection to my Galaxy J3 device. The network at the place I work requires a staff sign-in to get through the local network to the internet. Usually, right when I connect to the wifi, my phone prompts me that "This network requires sign-in" or some such thing, and directs me to the portal page. I guess this is called a Captive Portal?

I was trying to make this process quicker and as a result I pressed the "Use network as is" option in the wifi settings just to see what happened. Apparently that messed something up big time cause now I can't access the sign-in page no matter what I do or what I reset. In addition, my phone no longer brings up the sign-in page, and when I use a browser to try to force that portal page to come up (this usually works), it just times out. It seems to me the phone is now thinking that the wifi network has direct access to the internet so it won't go to the portal. And I can't find anything to undo what I did.

Here's what I've tried:

Forgetting network then reconnecting to it

Using Virgin Mobile's "Reset Network Settings" directions doing ##72786# on the keypad. That did absolutely nothing I could see. Didn't even remove remembered networks

Restarted phone

Tried adding the network manually

I don't know how to do this "root" stuff, but I tried to access the file under data/wifi/misc to delete it but I can't find it using the File Explorer (even with hidden files shown). This was from directions I found at How to reset Wi-Fi settings?

Anyway, I'm sure that's confusing but is there anyone who could help me with this?

Thanks!

Plasma Mobile in MultiROM Manager on Nexus 5
I tried to install Plasma Mobile on Nexus 5. It is very important to me to start testing it in MultiROM Manager first (with some other mobile operating systems).

I followed this tutorial.

How can I see a list of running apps with root privileges
I'm running CyanogenMod and recently the # sign showed up in my status bar. Now I wonder which program / app is causing this / is using root access. Is there a way to show a list of running apps which use root privileges?</p>

Is Nougat 'Emergency Info' synched?
I was reading on some new Nougat features just now, and it mentioned a new feature, that lets you make emergency information (blood type, allergies, emergency contacts, etc) available on the lock screen.

Got me wondering though, will that information sync on your Google account? If you enter that info on one Nougat (and later, theoretically) device, will it also be entered on other Nougat devices on the same account? Or will you have to enter it on each new phone/device going forward?

问:
Galaxy S6 Active always asking to sign in to WIFI
I have an S6 active running 6.0.1 that just started prompting me to sign into my work WIFI after the update from 6.0 to 6.0.1. I have used this phone for over a year on the same network and the password is saved. When I click on the notification from the home screen it automatically signs me in to WIFI until the notification pops up again asking the same thing. None of our tech guys have been any help. I've changed to another network with the same exact results (home and work). Anyone have a clue how to get this to quit and stay signed in? It's driving me nuts! </p>

问:
TalkBack, how to figure out what the non-text-reading sounds mean
I am trying to use TalkBack without looking at the screen, but even when I look I am not good with sounds because they distract me and I cannot figure out what they mean.

So, is there a resource, somewhere, which tells me, as a TalkBack help location, what the various sounds mean, so a blind person can know what they are and how to move their fingers I the touchscreen?

Furthermore, oes a keyboard like Swype reissue its own TalkBack sounds, or do these sounds come from TalkBack itself?

I either case, how do I go about, possibly blindly, figuring out what the various sounds mean?

Thanks..

Does Galaxy Xcover 3 Value Edition support Mifare Classic NFC tags?
The Samsung Galaxy Xcover 3 is one of the few devices that still support Mifare Classic NFC tags. It was released in 2015. Now Samsung have released an updated version, the "Value Edition" in 2016.

Does anyone know whether this new version still supports Mifare Classic NFC tags?

Something wrong using TalkBack with stock Contacts app
I am trying to scroll up and down the stock Contacts app, which I am doing by trying to place two fingers simultaneously on the screen and dragging up and down. When I do this properly I can hear the keys of a piano being pressed, and the screen scrolls.

I have to repeat this multiple times by lifting the two fingers and placing then back up the exec and scrolling down our down the exec and scrolling up.

Unfortunately sometimes, perhaps due to one finger landing on the screen a slightly different time than the other, I get one of the following two dialog boxes (and not the scrolling I was after):

Not what I wanted. What am I doing wrong and how do I fix it?
