Missing Cast icon in the Notification Center
I mean to cast my Android screen to my Windows 10 PC.
I pull down from the top, but I do not find the Cast icon, even if I pull a second time.

Can I fix this?

Using Android 8.1.0 (Oreo) in a J7 Prime.

Note 1:

Accroding to this, "Some of these steps work only on Android 10 and up."
There isn't any further specification.

According to this, without explicitly telling it, but shown in the images, I should have Cast available.

According to this, availability of Cast is "largely dependent on your phone's OEM skin... the Google Cast button... has been exclusive to Nexus and Pixel devices, even though other phones have the requisite software to use it."
One should install Quick Settings to be able to add the icon.
This opposes the implicit description above.

Note 2:
I am not certain about the relation between this Cast icon, Quick connect, Smart view, Windows 10 Connect, and the following 2 icons.

Note 3:
I actually mean to cast from Android to PC without a WiFi router, but that is a separate story.


问:
Is it possible to install a Wear OS apk from an Android phone?
I develop Wear OS apps and watchfaces at home with Android Studio, then use adb to install them to a physical watch.

I'm currently on a trip, and connected to my home development machine (via my travel Android tablet and Teamviewer) so I can continue development -- but since I'm not on my home WiFi, I can't use adb to transfer the apk.

Is there any way to do this? I can get the compiled apk onto my phone via gmail or gdrive, but don't know of any way to move it to my watch.

Any ideas?

Turn android into server to livestream its own camera and serial data
In my project, I need to turn an old android into a web server. I need to be able to access live video from this phone and be able to send/receive data to/from a mobile app.

Data received from the app will be sent via serial to an Arduino to carry out a respective task, and likewise data received by the Arduino will be sent to the app.

After a lot of Googling, I still can't figure out a solution.
How can I accomplish this?

How to increase the sample rate of the current measured from the Android kernel?
I need to monitor some applications power consumption of my Samsung A8, programmatically. I'm doing this by accessing the files:

/sys/class/power_supply/battery/current_now

/sys/class/power_supply/battery/voltage_now

The problem is that the kernel update those files every 10 seconds, so it does not produce sufficient power samples measurement to my experiment. I want to reduce the update time produced by the kernel driver to increase the sample rate. Ideally the kernel would update the values every half second.

From this post: How does the Android estimate the battery level without a current sensor?
I understood that I might find the name of the chip that measures the battery information by looking into a defconfig file. After searching for a while on the defconfigs from my kernel, I believe that the Fuel Gauge used is S2MU004 as specified in this file: https://github.com/prashantpaddune/universal7885/blob/e5ffd23305f0b09fe2bef3f8580df046dab232cc/arch/arm64/configs/exynos7885-jackpotlte_defconfig#L4415

But I'm still not sure about it. Would be the s2mu004-fuelgauge the name of the chip? If so, where can I find the driver? And then, someone can enlighten me on how to modify the driver to increase the sample rate?

This is the content of the dmesg.log file.

Here it is after:

问:
How can I know the hostname of an Android phone for use in SSH connection?
When setting up public key authentication on SimpleSSHD server on my Android phone, by http://www.galexander.org/software/simplesshd/

Quick start

Install SimpleSSHD.

On any computer which will connect to your Android device, set the port to 2222.  With OpenSSH, this can be done by putting these lines in ~/.ssh/config:

```<code>Host myphone
Port 2222
</code>```

Launch SimpleSSHD, and in Settings enable "Start on Boot", then manually start it for the first time.

Create authorized_keys in the home directory (do not use ssh-copy-id)

Optionally make .profile

how can I find out the hostname myphone for my android phone?

My phone is assigned different IP addresses from time to time. For example, I can move my laptop and phone to different LANs, and my phone can reconnect to the same LAN.

Some attempts from my laptop:

First attempt (fail):

```<code>$ ssh -p 2222 192.168.1.87
user@C6730:/data/data/org.galexander.sshd/files $ hostname
sh: hostname: not found
</code>```

Second attempt (fail):

```<code>user@C6730:/data/data/org.galexander.sshd/files $ ^D
Connection to 192.168.1.87 closed.
t@ocean:/home/t$ ssh -p 2222 C6730
ssh: Could not resolve hostname c6730: No address associated with hostname
</code>```

Third attempt (succeed with some luck by guessing):

I find all the hosts in the LAN by  sudo nmap -sP 192.168.1.0/24, and guess which host in the output is most likely the phone. it is something like android-c0f659b6548c28b2 (not the real host name)

Will android-c0f659b6548c28b2 change under some cases, for example, when the phone is restarted, moved to a different LAN, assigned a different IP address, ...?

Does anyone know what c0f659b6548c28b2 means? It is not the Mac address of the phone.

Can I customize the hostname of the Android phone?

Thanks.

Where do Android apps save their working state?
Where do apps store their working state?

Occasionally an app will crash, or I'll get the Android message that X app has stopped responding ("Do you wish to close?"). In either of those cases, after the app has crashed/closed, if I then switch back to the app via the switcher, the app's state is restored right in the middle of where it was previously, as if it had never closed.

However, if I were to close the app myself, such as closing it from the app-switcher view, or the phone rebooted, the app will start fresh, with no state saved/restored whatsoever.

I'm wondering if there's a way to manually save an app's working state, so you could restore the state manually within the app when you want, without the assistance of the "App isn't responding, do you want to close?"

Kindle Stuck on Lock Screen
Somebody gave me a Kindle - it is an older model (only has one external button - the power button), but it is stuck on the lock screen and there is no way to get past it.

Things I've tried:

Holding the power button for 20 seconds to reset it

Holding the power button for 40 seconds to reset it

Using two fingers to try to swipe the screen (in case voice mode is activated)

double-tapping the lock button

charging it and then trying the 20-second reset

If I hold the power button for just a few seconds, the screen darkens and if asks me if I want to Shut Down or Cancel.  But tapping the buttons don't do anything - as if the screen won't detect taps anymore - I'm thinking it is a hardware issue.  However, on the lock screen, if I tap the lock button, it's background does shift transparency, so it's detecting something.

Any other ideas for this?  The tablet is too old to bother with Amazon Support, and I don't know anything more about it except that I can't get past the lock screen.  It powers on and off just fine, though.

[update]

Well, it's been quite a few days since my posting, and noone has any suggestions.  I don't know what to do except to try taking it apart and check to see if some cable is loose.

WhatsApp reply via notification not working
I am currently on Android 9 Pie. Whenever I get a WhatsApp message and I try to reply to it from notification, it freezes. More frustratingly, it doesn't happen every time but say, 1 out of 3 times it happens.

Steps to reproduce:

Receive a WhatsApp message

Click Reply on the notification

Type message in the notification

Click Arrow (send) button.

Result:
The arrow turns to a circular progress bar and the notification stays like that. The message is not sent.

I have tried clean installing WhatsApp, it still persists. Not sure if anyone else is facing this. No other apps like Telegram or even the SMS app are having any such problem.

Any solution will be helpful. Thanks.

Driver not in list and official plugin unhelpful - how to print plain text to HP from Android?
I have a phone with Android Pie (LineageOS 16) and the HP Print Service plugin, and an HP OfficeJet X476 printer. (Which isn't an old model, under 3 years old office model). I often need to print text files such as plain text emails or downloaded XML files. My problem is that I cannot work out how to resolve the following printing quandary:

HP Print Service states that it prints plain text only from an app with a "print" menu item, not from the "share" menu. Unfortunately many apps including some I can't easily change, only provide a share menu for printing.

HP's FAQ comment "Can I print if my app does not have a print option?" acknowledges this but isn't helpful. It says "Yes but only photos and PDF" (3rd FAQ item at this time). Their forum says the same.

I've therefore looked at other well-known printing apps, such as StarPrint. The problem with those is, they need a driver selected, and my printer doesn't appear in the list of HP printers. So I can't select it. If there is some kind of generic (or generic IPP) driver, or an Android-specific driver rather than generic "Linux" on HP's product page, I can't see that, either.

(If I do find and install a driver, I'm hoping it'll appear in StarPrint's list for selection, but can't be sure.)

Is there an easy way of any kind to print plain text files from my phone? Or do I have to either convert them to PDF every time, or move them over USB to my desktop?

What can I do, to print plain text and emails easily from my phone, ideally via its share menu?

"Certificate not secure" error on Samsung Email app on Note 8
I have a Samsung Galaxy Note 8 (Android 9, One UI 1.0) and am using Samsung's Email app (which comes preloaded on Samsung phones) to access my work email.

Recently I went abroad and had to rely on various Wi-Fi connections (hotels, airports etc) for Internet connectivity. Suddenly, I have started getting an error when I launch the Email app, which says: "Certificate not secure for [my email address]. The certificate isn't from a trusted authority. If you continue with this certificate, your emails and account may be at risk." (Picture below)

The error keeps popping up if I click on "Cancel".

If I click on "View", all the important fields related to the Security Certificate are shown as totally blank, so it is difficult to know which certificate is causing the problem:

Since this happened, the email is not syncing now, i.e. I am now unable to send or receive new mails from the app.

I Googled a lot to resolve this problem and the two main solutions were (though I have no idea how well any of these would work):

Uninstall the Email app and re-install it. But I don't want to go down such a drastic route without getting to the bottom of the problem.

Find the offending certificate (Settings > Biometrics and Security > Other security settings > View security certificates) and delete that certificate. However, my problem is, the Email app is not showing the details of the offending certificate.

What is going on here and how do I resolve it? Have some "rogue" certificates been installed by those free Wi-Fi connections I used recently? If so, how harmful could those be and how do I get rid of it? Hopefully nothing serious!

And how do I get my Email app working normally again?

Limit number of installed apps
My kids both have an android tablet. With parental control I can limit the apps type to PEGI 7 for example, which works fine.

But they then keep installing apps until the device is full, and then doesn't work properly anymore.

What I am looking for is an option to limit the number of apps installed at the same time. So I can set that to for example 30 or 50. If they then want to install a new one they first need to remove one.

With googling on this topic I find a lot about time management, but I already have an app to arrange that. So this is purely to set the maximum number of installed apps.

I hope someone has an idea how to achieve this, either by a setting in Android, or by a third party app.

WiFi network limits connection time - can I "change my MAC" and reconnect?
On a PC, you can change the MAC address of a network adapter - Ethernet, 802.11 Wireless - and thus assume a different "identity" than previously.

Now, I'm stuck in a train station for a few hours, and am using my RedMi 3S (Android 6.0.1) to connect to the Internet. But - curse be upon their heads - they only offer "30 minutes of free WiFi". Of course, that has to be tied to some sort of physical identification, for them to throw you out after 30 minutes, right?

Question:

Can I change my MAC, literally, or do something else which will make the access point(s) think of my phone as another device than the one it know?

Could I need to perform any other, complementary, actions, such as delete the cached DHCP lease before reconnecting, or clear the browser cache? Or - is such caching not used when reconnecting?

recover smartphone after factory reset
Last friday, my Samsung smartphone somehow performed a factory reset. I do not know why (it fell on the ground, or my son triggered something, but that does not matter now).

I noticed it when during booting, I saw the samsung letters and after that the 'let's get started' screen where I had to choose a language to setup the phone.
I lost everything that was on my smartphone including some pictures. Most stupid of course, but I know I setup google photos to automatically backup my photos. However, when I checked google online, not 1 image was there so, I lost everything that was on my smartphone. I can live with that for most of the pictures but some I would like to get back somehow.

I tried to recover my data using several apps on my computer.
dr fone for android, fonelab for android, easeus data recovery.

Dr Fone took some time before completing with saying nothing could be found because I do not have root access on my samsung smartphone.

I already looked into rooting the phone but as far as I could read, rooting would cause a data wipe which I do not.

Is there any chance / method to recover data from my phone and how should I do that? The device is a Samsung A6 SM-A600FN (2018).

The lock screen widget, the normal widget, the status bar clock and the clock inside the app itself all occasionally show incorrect time (usualy between 10 minutes and couple hours before current time; not even always the same). Alarms won't work when this happens and lately it has been happening multiple times a day. When the clock gets "unstuck" it just jumps right to the correct time and sometimes freezes again. The internal phone clock probably work fine based on what the other apps show. It started about 3 months ago as once-in-a-week thing and has been happening daily for a month now (so I obviously restarted it many times during that time).

The device is Hammer MyPhone Energy with Android 7.0. and it is not even a full year old.

问:
A/B partitioning - which slot is really flashed?
I have a Moto Z3 Play with stock ROM and rooted it by Magisk. Phone is seamless updates and treble ready. Everything works fine. Yesterday system updater was trying to update to the newest version but it fails. I know, I changed boot partition so it can fail. I downloaded a full ROM zip file from Lenovo servers (PPWS29.131-27-1-15), unpack it and trying to flash the newest version by myself using fastboot.

The current slot was B, it contained PPWS29.131-27-1-11 version. So I changed to A and flashed all partitions from PPWS29.131-27-1-15 ZIP file on slot A.

Commands that I used to flash PPWS29.131-27-1-15:

```<code>fastboot getvar max-sparse-size
fastboot oem fb_mode_set
fastboot set_active a
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot erase modemst1
fastboot erase modemst2
fastboot flash bluetooth BTFM.bin
fastboot flash dsp dspso.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash vendor vendor.img_sparsechunk.0
fastboot flash vendor vendor.img_sparsechunk.1
fastboot flash oem oem.img
fastboot erase carrier
fastboot erase ddr
fastboot oem fb_mode_clear
</code>```

Then I tried to boot from A slot but it fails. The phone got bootloop and lands in stock recovery. I assumed that something goes wrong so I rebooted to bootloader and changed slot to B to boot PPWS29.131-27-1-11 version which was working fine. And then comes mindf*ck - after system start from slot B, I noticed that system version is now PPWS29.131-27-1-15. But how? I flashed partitions on A slot, not B. Even fastboot logs showed that I was flashing A slot.

When I changed slot to A with fastboot command is it really flash A partitions? Or just change which partition should boot in the next reboot?

Stuck on "Bootloader is unlocked" screen, can't boot into recovery
So I wanted to root my OnePlus 6 after updating to android 10
(OnePlus6Oxygen_22_OTA_041_all_1911142043_dde113e5 3cd0f9.zip)

I tried booting into twrp via fastboot using fastboot flash boot twrp.img
(twrp-3.3.1-x_blu_spark_v9.101_op6.img, my bootloader is unlocked).

I then tried rebooting directly into twrp, but now it's just stuck on the "Bootloader is unlocked" screen.

I can still boot into fastboot, but I can't boot into recovery or reboot normally since it just gets stuck on the bootloader unlocked screen.

Please Help!

Edit1: Changing my boot slot from b to a gives me access to the stock recovery. not sure where to go from here though.

Edit2: Fortunately, ManikandanGuru over at xda had uploaded the stock boot.img, which works perfectly.

How can I make sure Google's "Find My Phone" works when my phone is in power saving mode?
I recently couldn't find my phone, so I used Google's Find My Phone web app to try to locate it. The service couldn't locate my phone, and though I'm not quite sure why (there are a sea of settings), my guess is because it was in low power mode (and not connected to WiFi).

My phone is a Galaxy S10e. What settings should I use to make sure Google Find My Phone can find my phone even in "low power mode"?

I know how to set special app permissions and give them usage of background data even in low power and/or mobile data mode. I'm just not sure which app to give the permission too.

can copy file from one folder but not another
I am trying to get an apk from the aurora directory on the device onto a linux pc. There is not an issue copying in and out of the Download directory. If I connect the device with a cable and right click on the folder and list its contents in the terminal, it looks like this:

```<code>cardamom@northsea:/run/user/1000/gvfs/mtp:host=%5Busb%7A019%2C004%7F/Interner Speicher $ ls -la

</code>```

Now files from the Download folder can be copied to the PC without a problem but if I try it from Aurora, this happens:

```<code>cp: error reading 'app.some.app.330.apk': Input/output error
</code>```

If I list the Download or the Aurora folder with ls -la, all files have the same permissions.

I tried the suggestions here but it did not really help.

Then I went into a file manager on the device - one called 'open manager' which I installed from FDroid and copied the file I wanted from Aurora to Downloads. Now it gets strange - the file is visible in Downloads in the file manager on the device, but nowhere to be seen in Download when looking over usb!

Any ideas what is happening, how to remedy it?

S-Pen only (touch screen disabled)?
I take hand written notes on my Samsung Tablet S3, as well as my Samsung Note 8 phone, using the S Pen.  Both are on Android 9.  Palm rejection and other accidental touches are mostly rejected, but not perfectly.

I would like to have a way to turn off the capacitive touch screen (that registers finger touches) but leave the S Pen detection on.  In this state, the tablet or phone would respond to the S Pen only, and ignore all other screen touches.

I know there are apps that can perform this feature, but they mostly come with unacceptably broad permissions, including full access to the network, reading contents on the device, etc.  This seems like something that should be built into the OS, but I have not found it.

I should add that I own a paid version of Tasker, but am not very good at programming it, in case someone has a good solution for Tasker.

Any advice or hacks?

How to enable debugging in ASUS Zenfone Selfie Pro 4 without seeing the screen (touch works BTW)?
[The similar questions are related to other devices and I don't intend to do factory reset.]

I cannot see what is being 'shown' on the screen, only interact through fastboot or randomly touching the screen.
The wifi is also working.

If I could enable debugging, I could use scrcpy to see and interact using mouse on a linux computer.

I suppose I can use fastboot to root/unlock/install apps. But I have no experience doing that. The only command I succeeded was this:

```<code>fastboot -s H7AZCY5468078HN oem device-info
...
(bootloader)    Device tampered: false
(bootloader)    Device unlocked: false
(bootloader)    Device critical unlocked: false

(bootloader)    Sysconf isn: N0CZ1738MB0033372
OKAY [  0.110s]

Also, touch-guessing until enabling debug seems impossible in practice.

How do I troubleshoot mounting my phone?
❄ I have a  Moto G6, running Android 9 (specifically PPSS29.118.15.11.2, Security Patch Level Oct 1,2019)❄ and when I connect it via USB I have an option (under USB Preferences) to "Use USB for ... File Transfer" which is selected.

The "Use USB for" options that I see are these:

File Transfer

USB Tethering

MIDI

PTP

No data transfer

With "File Transfer" selected, the phone appears as an external drive on my desktop (Ubuntu 18.04.3 LTS) but I can't move anything on or off it and the mounted drive shows no directories and my desktop properties say that "Permissions could not be determined".

I installed mtp-tools as suggested in answer to phone mounts as media device not usb storage but that didn't change anything.

I'm not even sure what "MIDI" is for, but with MIDI selected, I don't even see my phone mounted as a drive.

If I select "Use USB for ... PTP" I can mount the DCIM and Pictures directories. I was able to drop an MP3 into my Pictures directory and then use the Files app to move it to the Music directory, but that's a poor substitute for actually mounting it and moving files back and forth. It does confirm that the issue isn't the cable (as in this 2013 question: How do I mount my phone?)

I read through two questions that were solved by enabling USB Debugging: How to get USB file transfer working on Oreo 8.1? and Android Pie only showing two folders to Android File Transfer but that didn't work for me. (Note, in 9.0 you have to find your Build in the System Settings and tap it 7 times to even access developer settings. From there you can enable USB Debugging).

Any new and different tips for mounting my Android 9.0 so I can transfer files to and from it?

App ratings adjusted for numbers of votes?
Rankings of apps by rating are typically useless because the app ratings are not adjusted for numbers of votes, and therefore the top of the ranking is invariably saturated with many screenfuls of 5-star apps each having only a handful of votes, thus obscuring apps with slightly lower ratings but much higher numbers of votes.  Needless to say, the latter ratings are vastly more reliable.  These are the apps I'm trying to find.

Does anyone know of an Android app search service that allows ranking results by app ratings somehow adjusted for numbers of votes?  (E.g. use the standard rating minus 1 or 2 standard deviations.)

Facebook Messenger keeps on playing sound in notification
I'm using facebook Messenger on a Samsung Galaxy S9. Since a few months now, Messenger keeps on playing a notification sound when receiving chat messages even when I change the sound to Silent.

Let's be precise :

When going in Messenger parameters and choosing a notification sound, there is no "silent" sound (and I'm pretty sure it existed before)

When going into "Manage notification" from the app which leads to the notification management of the OS, I can chose "silent" as a sound but after a while (1/2 hours or so, sometimes less), messenger changes it back automatically to its default sound.

That's driving me crazy. I want to keep notification as I used to : vibration, preview but no sound.

I tried to delete and reinstall the app, nothing has changed. I even left a message in the Play store.

Any idea ? Thanks

Hi guys I am setting up an android system for a company, one of the requirements is that "employees can't factory reset/ wipe out data of a device". I have already done the proper implementations on the OS itself. however I was looking throught the recovery.img and boot.img files to see if I could modify any xml file or anything to hide or set password auth for the factory reset and wipe options from the recovery.

How does Android treat files bigger than free space remaining while recording?
I've spent the entire day trying to solve this issue, it seems paranormal but (sadly) it's true and I didn't find a way to solve it.
Yesterday I recorded a very important video using my Xiaomi and Quick Video Recorder (I used it more than once and everything has always been great), I had something like 3Gb of free space but I didn't check it and I was recording with high quality.
Android told me that was running out of space, so I suddenly stopped recording.
I checked the video and used VLC to replay it and everything seemed to work fine.

After about 30 minutes, the file was missing. I checked everywhere, rooted the phone and tried with recovery applications such as Dr.Fone, but the file is completely disappeared.
To be 100% sure I didn't dream it I also checked on Google Takeout and it confirmed I actually used the camera during that time and suddenly opened VLC to replay it...

How's that possible? Does Android delete an entire video when it's too large? Is there a way to recover even a small portion or to show logs of camera activity to understand where's the file?

I didn't know what to do so I opened adb shell and tried with ls -Rlat | grep '2019-12-18\ 17:' (I was recording around 5pm) and that's the result:

Android 9 Pie says 'encrypted', but phone can receive calls after reboot (before entering screen lock password)?
I have a new Optus branded ZTE phone (Android 9 Pie). I added a screen lock password. Apparently it is now automatically encrypted -

Settings / Security & location / Advanced / Encryption & credentials / Encrypt phone = "encrypted"

When I reboot the phone, I had expected for the phone to request my password before it got to my home screen (my older phone did this). However, to my surprise, upon reboot... the phone boots to the home screen. How can it know what my home screen looks like before I even enter the password?

In addition, it can receive calls? Further, if I swipe down and click 'Screenshot'... it will perform the screenshot and add it to Local / Phone / Pictures / Screenshots

What am I missing?


问:
Unable to archive IMAP email with GMail app
I'm using the Gmail app on a Pixel 2 running Android 10. I'm connecting to a private IMAP server (despite the app name, "Gmail" is a general-purpose mail client, not just for Google Mail).

How can I get it to recognize my Archive folder?

My IMAP server (Dovecot) offers an Archive folder, which is honored by all other IMAP clients (Roundcube, Windows 10 Mail). The Andoid Gmail app, however, does not show an archive button when reading the mail, and swiping will delete—rather than archive—the message.

When I'm reading Google Mail, it works as expected; there's an archive button next to the trash, and swiping archives the message. With my Dovecot account, the archive button isn't shown, and swiping moves it to the Trash folder.

Here's what the IMAP server returns for available folders:

```<code>d list "" *
* LIST (\HasNoChildren \Archive) "." Archive
* LIST (\HasNoChildren \Sent) "." Sent
* LIST (\HasNoChildren \Drafts) "." Drafts
* LIST (\HasNoChildren \Junk) "." Junk
* LIST (\HasNoChildren \Trash) "." Trash
* LIST (\HasNoChildren) "." INBOX
d OK List completed (0.001 + 0.000 secs).
</code>```

This is correct, and is honored by other clients.

In the Gmail app, if I click on the hamburger menu when viewing a message, I can select "Move to", and it shows an Archive folder there (in fact, Archive is the only folder listed there). Selecting this does move it to the Archive folder. This is unworkable, though; I need the Archive button while reading, and I need swiping to archive instead of deleting.

Samsung device isn't connecting via USB cable for file transferring
I am using a Samsung Galaxy J8 device . My phone doesn't have any SD card. I was able to browse files of phone from my PC(ubuntu os) , even I could debug my app from android studio.  But suddenly I am not able to do so. When I connect my phone via USB to my PC , it is only charging . What I did so far is following.

Enable developer option and usb debugging , changed default usb configuration to file transfer and image transfer and MIDI .

Restarted my phone.

Restarted my PC .

Change of USB cable and port .

At last factory reset .

After trying all above things , still I can't connect to phone via usb cable .

I think my pc , usb cable , usb port are working fine . Because when I connected another device , it shows me the following dialog .

I used to see the same dialog for my phone, but right now,as I mentioned, my phone doesn't show me such dialog.


问:
What is actually occupying the internal storage for the apps, and how to get rid of it?
I have a Huawei P8 Lite, but this should not be related to the actual device. For a while, the free space on the internal flash just keeps vanishing without installing any new applications. I am storing the media files on the SD card, which is confirmed in the file manager. The file manager says, that my apps take 9.5GB from the internal storage. When I select all the apps in the Google Play application, those take only half of this - not speaking about the fact that most of them is already moved to the SD card (I got that some portion still remains in the internal storage). It can't be the firmware, as that is shown separately in the file manager.

So selectin all apps from which most part is not even there yields only half of the occupied space. What the heck is the mysterious other half? I can't imagine that cache and application-specific data could be that much, as the application widget in the settings is not confirming that.

Is there any app, that actually shows in a spreadsheet all installed apps, the associated storage capacity occupied on each storage device?

Applications don't recognise internal storage partition 2 mounted as external sd card
So I have a Chuwi Hi10 Plus running RemixOS 2.0 (Android 5.1.1). This was originally a dual boot tablet, but I deleted Windows, so now the device has 45 gigs of storage free on the drive. I formatted this part as Fat32, because I wanted to mount it as an sd card. I modified the fstab file in the boot image, to mount this new partition where normally an external sd card would get mounted. The partition gets correctly mounted, I can read and write it with Root Explorer, but the applications don't see it, so I can't really use it. What else do I have to do so that all the applications on the device recognise it?

The original fstab file (I included only the relevant part):

```<code>##############################################################
# Source: device/intel/mixins/groups/storage/sdcard-mmcblk1-4xUSB-sda-emulated/fstab

*/block/sdb*                            auto             vfat    defaults                                   voldmanaged=usbdisk2:auto
*/block/sdc*                            auto             vfat    defaults                                   voldmanaged=usbdisk3:auto

</code>```

The modified version (last 2 lines):

```<code>##############################################################
# Source: device/intel/mixins/groups/storage/sdcard-mmcblk1-4xUSB-sda-emulated/fstab
##############################################################
*/block/sda*                            auto                 vfat    defaults                                   voldmanaged=usbdisk:auto

*/block/sdc*                            auto                 vfat    defaults                                   voldmanaged=usbdisk3:auto

</code>```

As you can see, I also modified the second to last line, because I wanted to have the actual external sd card mounted at usbdisk4, since the new partition would be mounted in its place. I set the flag to defaults, because the voldmanaged option wasn't working. Below you can see a screenshot of the partition succesfuly mounted:

Do Magisk modules pose a privacy risk? How to overcome?
Further to this excellent answer here by Irfan Latif How Magisk works? and considering that Magisk modules need not be open sourced (Are all Magisk Modules Open Source?), the question is

Do they pose a privacy risk?

(Risk as defined here)

I guess the answer is yes, for instance a battery performance module needs to know the device identifiers to tune the parameters (Lspeed d, FDE etc) but wanted to be sure

and if so, what can one do to protect privacy - outside of not using them :(

Note:Some modules like Lspeed create an app too but restricting app using XPrivacyLua seems pointless if the module itself is a risk.

Main super user app not working on Redmi note 6 pro
I rooted my n6p (after unlock of bootloader) using TWRP and flashed Magisk which installed Magisk manager. Many root checkers showed my phone was positively rooted.  After that I was using titanium backup as superuser  app, it was working fine and other apps also got super user access. But titanium b. has known issues with Magisk (https://github.com/topjohnwu/Magisk/issues/672).
After titanium backup was denied superuser access a couple of times I tried to uninstall and install tb, but now it just keeps stopping whenever I open it.
I tried using all sorts of superuser apps, root explorers, bash scripts, ads remover etc but ALL of them are "denied superuser rights".
Also other super user apps including tb I install are not detected by Magisk.

Can any mediatek android use HotKnot as long as the appropiate files are included in the ROM?
Where I am currently living, my government has blocked internet access.

We are sending important messages to each other using various mesh network apps like 'firechat', but the problem is, many of my friends don't have these apps installed on their phone and they can't access them from the app store or the internet.

Since I often have to troubleshoot without access to the internet, I like to be prepared for various file delivery methods in case one method doesn't work.

My phone is using a ROM that I have compiled myself and thus I can include functionalities into it that are not normally present on many phones, like FM radio, call recording, IMSI-catcher detection, etc...

Could I use HotKnot to send files to another phone if my phone is not a Chinese phone which had HotKnot installed on it originally?

I am wanting to know if it would be worth integrating the HotKnotBeam Service, Share, and Connectivity apks on my mediatek phone's ROM just in case I might need them?

If not, which devices could still use HotKnot even if the service wasn't on the phone originally?

问:
How to share the file names of all the files in a folder in Android?
It is being surprisingly hard to achieve. I've tried so far:

Download file manager apps from Google Play. Unfortunately, "share" shares the files, not the file names. None of them had a option like copy file names

Download backup apps. Unfortunately, none of them backup the file names of a folder.

Any idea to copy to the clipboard or share the file names of all the files of a folder?

Bluetooth media buttons don't work when phone is locked
I have bluetooth headphones (Anker) which include a play/pause button. This button only works when the phone (Nokia 3.1) is unlocked.

How can I enable bluetooth media buttons to work when the screen is locked?
