There's no limitation for internal backups and their uploads to Drive. It's not unusual that users have backups in size of 1GB+ due to all their media files.

Backups on Drive will be completely deleted after 5 months of inactivity and that's all.

Use WA desktop version.
[General Questions and Answers] xda-eh:
Actually it's the mobile app that retains the full history, whereas the desktop version only keeps the more recent one.

Guys please help

I need to backup whatsapp data from my huawei x3 to new mobile honor magic v2 please

I used manay applications with pc and without pc .. but when I am installing whatsapp on the new honor magic v2 can't read the backup
[General Questions and Answers] WoKoschekk:
1. install WA on your new phone

2. run WA once but do not verify and then close WA

3. open a file browser app and search for /internal_storage/Android/media/com.whatsapp/WhatsApp/Databases

4. copy the backup file "msgstore.cryptXX.db" into that folder

5. run WA again, verify your phone no and the local backup should be found
[General Questions and Answers] Chrypsisilon:
Hello and thank you for all the informations.

I also local backup all my DB since 2012 and have seen this strange behavior, but there also were days who the size went back to the usual one.

Never deleted something.

From 2012 - 2022-07-10 it always fine

msgstore-2022-07-10.1.db = 278 MB

msgstore-2022-07-11.1.db = 188 MB

msgstore-2023-01-28.1.db = 192 MB

msgstore-2023-01-30.1.db = 172 MB

msgstore-2023-04-12.1.db = 172 MB

msgstore-2023-04-13.1.db = 66 MB

msgstore-2023-07-16.1.db = 67 MB

msgstore-2023-07-17.1.db = 194 MB (Until 2023-07-21)

msgstore-2023-07-22.1.db = 67 MB (Until 2023-07-24)

msgstore-2023-07-25.1.db = 195 MB

msgstore-2023-07-26.1.db = 67 MB

After 2023-07-16 with 67 MB i got often around 67 MB - 69 MB,

as well as 195 MB - 200 MB between 1 and 15 days, last time 2024-05-05

msgstore-2023-10-23.1.db = 67 MB (Last normal Backup)

From this date, there are usually 2-7 incremental backups and then a full (~69 MB or ~200 MB)

What is really strange, why were sometimes still full backups around when most days were 65.5% smaller?

It looks like there would be all data at your phone and just get lost when you wanna restore it at the new one.
[Samsung Galaxy A21s Questions & Answers] Nazo:
First, to clarify, I have the Samsung Galaxy A21 (there is no dedicated forum, so it seems we A21 users must use the A21s forum.) Although this may at least somewhat apply to the A21s (it may actually have the advanced service menu, so may at least have that as an option. The A21 is considerably more gutted in even the most basic functionalities.) One bit of confusion on my part is the actual SoC is a MediaTek, not a Samsung Exynos. However, all warnings regarding these exploits list "A21" so I'm assuming that the modem may still be a Samsung modem. Though of course it may just not apply and they really mean the A21s (these models are so completely different they really should not have been given the same number,) I have no choice but to assume the A21 is included until someone says otherwise.

The main vulnerabilities are these four:

CVE-2023-24033

CVE-2023-26496

CVE-2023-26497

CVE-2023-26498

Apparently there are 18 in total, but these are the ones that allow "zero click" remote code execution (presumably with at or near root access.) One thing I've been unclear about though is if you have to actually accept the call or not. The implications of the warnings seems to be that all they need is your phone number to initiate the exploit (which would mean that bad actors could just simply use an automated system to run through basically every number if they really wanted.) Though to me it would make the most sense if it actually required you to accept the call. (I'd really like some clarity on this as that would mean simply rejecting any call not known to be safe would usually be sufficient.) For now I have to work with the assumption it truly is "zero click" as they describe it.

Given that VoLTE is normally not an option the user can toggle (especially in recent ROMs) there seems to be basically no way to turn it off these days. Phones used to sometimes have a toggle in the cellular settings, but not anymore it seems (probably due to it being basically required now.) I tried to enter the advanced service menu (*#26833662#), but it said not supported when I did. The standard service menu does not have any options or controls (let alone anything regarding VoLTE.) I remember in the past on an older (less locked down) phone I did have options to enable/disable VoLTE (though it didn't work due to the hot flaming mess that is VoLTE -- it really should have been required to be standardized and enabled across all devices physically capable of it before the 3G cutoff) via one of the service menus, but unfortunately this one doesn't seem to have that. Is there any other way I can disable it and at least keep my cellular access? I realize this means data only, but that leaves at least some possibilities such as VoIP calling like Google Voice and, more importantly, does leave me access to online things when I don't have WiFi.

It should go without saying, but I do have WiFi calling off, so no issue there.
[Samsung Galaxy A21s Questions & Answers] Nazo:
Bump. There is still no security update on mine. There may never be. I wouldn't be shocked at all if it's abandoned at this point. Even just a data only connection would have to be sufficient until I can come up with a better phone solution if that's what it takes, but I need to at least be able to use it for some basics on data, so removing the SIM isn't going to work.
[OnePlus 11] mr_stoosh:
Hi all,

I just picked up my OP11 (UK) and the for some reason the OTG USB is not recognised by the device. I'm not new to OnePlus devices and have switched the OTG toggle on, I've tried developer options and switched the default USB option to File Transfer.

The USB OTG works on my other android devices, so it's not an issue with the USB stick, can anyone assist?

Thanks in advance
[OnePlus 11] blackhawk:
Try toggling Developer options off temporarily.
[OnePlus 11] mr_stoosh:
I've managed to sort it out. For those having the same issues just go into settings and reset all settings and that should do the trick.
[OnePlus 11] mr_stoosh:
Thanks that's a good shout
[OnePlus 11] blackhawk:
Yay!

Unfortunately that's pretty drastic and like a factory reset although it may fix it, it doesn't find the root cause. Meaning if it reoccures you're boned, again. Finding the root cause can be a pain but it's a better plan. Usually you can find the issue in a matter of minutes, or hours over a day or a week. It seems like a daunting task at first at first but it rarely actually is.
[OnePlus 11] tupaa:
i dont know how or why but it worked! thank you
[OnePlus 11] blackhawk:
You're welcome.

Voodoo. Developer options can occasionally create issues. It's sort of betaware so it can get cranky. Not hard to deal with once you know to check it and overall it's very useful.
[OnePlus 11] shadowofdeth:
Good stuff. Worked.
[OnePlus 11] marcmarshall:
Yes!
[OnePlus 11] blackhawk:
Yay! You need to be aware that Developer options while very useful occasionally can go nuts. Just had bt sound Q start puking on me*. Had to retoggle one of the bt options without closing Developer options, whatever🤣

Sometimes the simplest options are the best.

Don't go nutz until you try the easy fixes...

Rethink firewall stop logging a few minutes ago wtf? After screwing with it for 10 minutes I finally just toggled it off then back on. Logging's back online again... like nothing ever happened.

Two minor mess ups in one hour.

Virus, trojan maybe? Nah just Android being Android😎🤣

*hadn't used it for a week or two, so it probably didn't happen today. Might have accidentally toggle it closing Developer options with side swipe controls that I use.
[OnePlus 11] marcmarshall:
Yes, often just a reboot is what's needed. I will stay mindful of this.

Thanks for the fix!
[OnePlus 11] blackhawk:
Not even a reboot. Fix both without one.
[OnePlus 11] marcmarshall:
"reboot" in the metaphorical sense eg; on/off
[FYT Android Head Units] dishe2:
I've been trying to troubleshoot an Atoto S8 Ultra (uis7862 based unit), and I'm having a really difficult time figuring out how the storage works.

I've noticed that when my unit resets (either on its own due to a bug or with the factory reset command), when I reboot the system seems fresh in that none of my apps are installed, but certain parameters persist. As if there's a different partition for user data that isn't where the apps/data go, and only one of them gets cleared with a factory reset.

For example, all of my paired bluetooth devices in BT1 (Atoto uses the dual bluetooth system, with BT1 being phone connections) were still there after factory resets, and using the file explorer I found folders for all of my previously installed apps as well as downloaded files and saved screenshots. No matter how many times I reset, that stuff was still there.

I used the Twipe All script from @surfer63 and it finally cleared everything, but now it appears that other settings have cleared / defaulted that I'm not aware of, which I think came a certain way from the factory. For example, there's a transparent car in my backup camera view now. It looks almost like the window for the virtual 360 camera but its not, it's just an overlay and it won't go away. This started only after the twipe command, so I feel like there were partitions wiped with settings set at the factory. Additionally, now my Bluetooth system is actually VERY peculiar. When anything plays off a paired bluetooth device, it pauses playback elsewhere. For example, a chime notification on my phone will pause spotify natively on the unit for the duration of the sound. This is not a feature the unit had by default and there is no discernible way to make it stop!

I don't even know where to begin trying to trouble shoot this! I reached out to customer support, and they said they have never heard of this working that way!

They recommended I capture a debug log as follows:

Create a folder called blinkdebug and reboot the system, it will start capturing any data. They showed me 2 videos of this working on their test bench, and I can confirm it works on another unit a user has, but on mine it does nothing. The folder is empty, whereas on other Atoto devices I saw a file created with log info there. Like the blinkdebug system doesn't exist on my unit post twipe script or something. What could this possibly be?
[FYT Android Head Units] surfer63:
I don't have a clue either. What I do know is that in the Mekede units in the "/system/bin" folder there are three binaries "blink", "blink5" and "blink131". and a daemon "blinkd". These are soflinked from "/oem/bin".

These are started from the "init.rc" in the root folder /. (you can consider init.rc (actually multiple .rc files) as the startup scripts).

blink -> /system/bin/blink
blink131 -> /system/bin/blink131
blink5 -> /system/bin/blink5
brlinkd -> /system/bin/brlinkd

I can only guess that blink means something like "bluetooth link" ?? (and maybe I'm completely wrong. I can't find anything about it).

There are also bt_* files for bluetooth so again: I can be completely wrong, but do you have those "blink" binaries as well?

I mentioned it somewhere else, but there is also the /sys/fyt folder. This folder is also used to store settings that are FYT-only settings and fall outside the normal android partitions and might not be touched by Android resets. They "were always" touched when you do a full firmware flash with "twipe all", but you have a very exclusive device ;)
[Touch Diamond, MDA Compact IV General] ko0l:
When you set the phone to vibrate mode, both the ring and system vol slider slides all the way down. This causes no sound in anything even with using earphones when playing music and watching movies.

Does anyone have the same problem and have a fix for this?

Thanks in advance
[Touch Diamond, MDA Compact IV General] kaos_king:
Yep, same problem, and so does everyone else.

Solution = Phone Weaver (phweaver)
[Touch Diamond, MDA Compact IV General] mouldy mushroom:
when you put it as vibrate it turns off all phone sounds (it is standard in all windows mobile phones) if you turn the volume up and put the headphones in all phone sounds will go through the headphones.
[Touch Diamond, MDA Compact IV General] defaria:
Sounds like a non problem to me. What would you expect if you have the volume turned all the way down? No sound. If you have head phones and plug them in then turn of the volume. It'll only be in the head phones.
[Touch Diamond, MDA Compact IV General] ko0l:
Nah, the problem when the headphones is plugged and sound is turned on. If the phone rings, it still rings through the speaker (not the headphones). So if i'm in a library or something, i can't listen to music without turning the sound on. When the phone rings it will disturb everyone. All my phones i used before non-windows phones from nokia and sony ericsson still had music through the headphones even if the phone was on vibrate.
[Touch Diamond, MDA Compact IV General] defaria:
Ah I see what you're saying now. Personally I see it as a good thing. If I had the phone charging, i.e. not in my pocket or where I could feel it, and was on BT stereo headset but didn't have it plugged into my ears then I would be totally unaware that I was receiving a call. But I must say that I'm not in the library often (last time was probably about 1982) and I don't use vibrate at all really.
[Google Pixel 7 Pro] Skuddle:
I need a wall charger for my Pixel 7 Pro. I also need some way to connect my P7P to my computer's USB-A female connector so I can transfer photos back and forth. I tried searching on the internet but after spending 1/2 an hour looking on the internet for something my mind just turns to mush.

I came up with the Google 30-watt charger and 3-foot cable for $35 and a 6-foot C-to-A cable for $17 but somehow that seems like 'way too much money. What can I buy at a more reasonable price that would fast-charge the P7P and connect to my computer?
[Google Pixel 7 Pro] schmeggy929:
I can go on Amazon and get both in less than a minute. cables are between 5.00-25.00. Don't know where you are looking. You only need a charger than can handle 30 watts, as the pixel 7 pro can only pull 23 watts max.

PS I personally only buy good rated cable(mostly Anker). They run from 15.00-25.00. Highly durable cables.
[Google Pixel 7 Pro] yurishouse:
For data transfer search for

USB 3.0 a to c cable

On Amazon, but don't buy anything too long, 3ft is more than enough in most cases (for data)

For chargers basically any 45w PD chargers will do. Anker and so on. 30w will also work but I prefer to have some excess in case I want to charge something that does go faster (power banks, for example)

For charging cable... Most c to c cable will do fine, I've been using the discount best buy home brand cables and they're fine. A phone like pixel won't draw nearly enough current to make the cable thickness matters.
[Google Pixel 7 Pro] MrBelter:
To be fair even an old 20W PD charger will do if you have one knocking around given the P7P peaks at 23W.

Personally i like the Anker Nano III (which is 30W) and the Anker 643 cable (because its really floppy). For data transfer i just use any old USB 3.0 (or higher) USB a to c that i have laying around.
[Google Pixel 7 Pro] jaseman:
I know you want to save money. Who doesn't? But the fact is that you get what you pay for! You DO NOT want the cheapest, or the most expensive, in virtually anything (except maybe a heart, or brain surgeon...then I would go with the best)! Otherwise stick with the middle and you will not go wrong as long as the specs fit the need.
[Google Pixel 7 Pro] otonieru:
I like my old Choetech 15W PD charger. Because it use 5V - 3A , so the heat reside more on the charger block instead of on the phone (phone heat up more when the charger use higher voltage like 9V for example) an it still fast enough to charge my pixel which only tops at 23-24 even when using faster charger.
[Android Q&A, Help & Troubleshooting] mknick89:
This is what i have going on. I have quite a few android phones i use to mine different cryptocurrency. most are older snap dragon ARM phones.

I am looking for something already created or if it is possible to create.

Is it possible to load a custom to the phone getting ridding of all unnecessary apps and programs. All i need to mine is wifi and my mining software which is run through Userland/Ubuntu. i currently have everything disabled and background process limited to try and help.

I looked into open source OS, but i learned it isn't one size fits all and a lot of my phones aren't even compatible with what developers have available for use.

I figured if there is something like this out there someone here would know. sorry if my description isn't that great and i hope this is in the right section.

any ideas or help would be greatly appreciated.

I understand why, but i don't. need an entire operating system ideally just loading a few functions would be best for my set up.

i agree mining is a pretty serious hobby/endeavor, but you are spreading misinformation, it can be done on cell phones and i've been doing it for 2 years. some people smarter than me made it possible with software and it is quite more profitable if done right than using gpu and cpu, especially on the network i mine.

on youtube i saw some people booting android, cant finding anyone disabling the zygote functions though, most cases people still want phones to work lol
[Android Q&A, Help & Troubleshooting] Renate:
That all should work fine.

You can just use the shell command stop which will stop all things Android-ish.

You can try out whatever you're doing without permanently disabling Android.

The only gotcha is to make sure that ADB is started inside init/init.rc and not by Android.

setprop persist.sys.usb.config adb should do that.
[Android Q&A, Help & Troubleshooting] ethical_haquer:
Can you please explain it a little more? So you delete some files in a specific directory, and that's it? You have to use ADB for the commands I guess? And is it really just the Linux kernel, or modified? Sorry for the childish questions. 😊

i have one more question to. should upload ubuntu to a certain directory or boot file or anything so the phone knows how to boot. or how does that work. this information is gold and i would like thank you for your time again
[Android Q&A, Help & Troubleshooting] Renate:
I write bunches of command line (shell) applications for Android and they are mostly identical to main line Linux.

Ok, some of the paths are different and a few other details are different.

You can write shell utilities that interact with Android over Binder, but those won't work if Android isn't running.

Just get the Android NDK which has the cross compilers and headers.

A "hello world" program should take you five minutes.

Just type uname -a and you can see what Linux kernel version you have.

You don't need to delete anything, just run your program.

If you want, you can stop Android temporarily by stop

To prevent it from ever running you need to patch some .rc file so that zygote (32 and/or 64) doesn't ever start.

To write to the screen (without Android's surface flinger running) you'll have to play with the framebuffer yourself.

You have an OS already on your device, it's Linux.

If you want to run Ubuntu on your device, that's an entirely different project.
[Android Q&A, Help & Troubleshooting] mknick89:
i launch the files for mining software from inside ubuntu. Currently accessing ubuntu through the userland app. here is a 2 minute video of someone on cpu launching a similar version of my program made for linux. same steps i go through pretty much would this look like it could be done from the linux command on a phone. or do you think it is compatible really?
[Android Q&A, Help & Troubleshooting] mknick89:
only first minute matters of video
[Android Q&A, Help & Troubleshooting] Renate:
There's no audio and I'm not at all interested in mining.

If it's not a GUI app, just recompile it using the Android NDK.

[Samsung Galaxy S22 Ultra] chris2412:
To those that have use the phone for a year what is your battery health percentage without battery protection and with battery protection, im just trying to see if using the battery protection is worth it or not
[Samsung Galaxy S22 Ultra] neilth:
There is no question concerning battery protection, if you use a device with a lithium ion battery and only use it between 30 and 80 % this will greatly extend the useful life of the battery. Using a smartplug and software to control the charger plugged into it, I have a five year old Pixel phone with a battery health percengage above 85% that’s still working fine.

I only wish that Samsung’s battery protection option was 80% instead of 85%, which would better enhance battery life.
[Samsung Galaxy S22 Ultra] Marcelocohenarg:
Almost a year with the phone (10 months), always used the battery protection. Stock One UI 5.1, Snapdragon version.
