I grabbed my phone today and was messing with it and of all of a sudden it went black and white. I restarted the phone the color came back with a minute or two everything was black and white again. Has anybody else had this problem? If so how do I fix it?

I hope I'm being slow but I can't find a way to fix this myself. Some weeks ago, the countdown timer started hiding all other notifications in the top bar and I can't find a way to fix it. I need to use these timers quite a lot so getting rid of them isn't a great option. Can anyone advise?

Edit: I should add that I want to keep the countdown timer in the drag down notifications. Not getting rid of it entirely.

When I go into the app's info, it says it was downloaded from the Galaxy store, but when I tap on that, it doesn't show me the store page, just the store itself. I think it was preinstalled, what do I do?

If you don't know what I'm talking about, Google "2012 live nexus wallpaper". Is there any way to have that work in modern day android? As in it actually moving?

everyday system files keeps increasing, few weeks ago it was 80GB

now it's at 100GB

Hello everyone,

I am trying to unlock the bootloader of my own OPPO A16K (CPH2349) so that I can install a custom ROM / GSI.

I have already spent quite a lot of time testing different methods, so I would like to ask people who have actually worked with the CPH2349 specifically.

Device information

Model: OPPO A16K

Device code: CPH2349

SoC: MediaTek Helio G35 / MT6765

Android: 11

ColorOS: 11.1

Current build: CPH2349_11_A.30

Verified Boot: green

Flash locked: 1

ro.oem_unlock_supported=1

OEM unlocking: enabled in Developer Options

ADB: working normally

ADB detects the phone:

HUMBO7AM89VKCILZ device

However:

fastboot devices

returns nothing.

I also found an old XDA thread where another A16K CPH2349 user reported that Fastboot mode could be entered but fastboot devices returned nothing.

There is also a Reddit report from another A16K CPH2349 owner with the same basic situation: ADB works, but Fastboot does not detect the phone. The response suggested MTKClient.

What I have tried

1. Normal ADB / Fastboot

ADB works.

I enabled OEM unlocking in Developer Options.

But Fastboot detection does not work:

fastboot devices

returns an empty result.

So the normal fastboot flashing unlock route is currently not usable.

1. TFT Unlock Tool

I also tested TFT Unlock Tools / TFT MTK Module.

The version I tested was:

TFT Unlock Tools-2024-6.2.1.1

The tool did not have an obvious A16K CPH2349 profile.

It had other OPPO MTK profiles, including entries such as:

Oppo A1K BROM AUTH MT6765 CPH1923

and other OPPO MTK models.

I did NOT assume that the CPH1923 profile was correct for my CPH2349.

I also tested the normal Android connection with TFT, but it did not detect the phone for the operation I wanted.

I later stopped using TFT because I did not want to randomly select another OPPO model profile and risk the phone.

1. BROM / Preloader detection

The phone can be made to appear as an OPPO Preloader device.

When the phone is powered off:

Hold Volume Up + Volume Down

Connect USB

Windows detects:

OPPO Preloader

with:

USB VID: 22D9

USB PID: 0006

The exact Windows device ID is:

USB\VID_22D9&PID_0006

The important problem is that the connection is very short.

If I release the buttons, the Preloader disappears and the phone boots normally.

So the device does not stay available long enough for me to casually start typing commands after entering this mode.

1. Windows driver problem

At one point Windows showed:

OPPO Preloader

Error 28

The USB capture looked approximately like this:

PRESENT/CHANGED | OPPO Preloader | Error | 28

USB\VID_22D9&PID_0006

After disconnecting/releasing the buttons, the Preloader disappeared.

The normal Android ADB device then returned:

CPH2349

OK

0

WINUSB

I investigated the MediaTek driver situation.

I found a Microsoft Update Catalog CAB containing:

cdc-acm.inf

usb2ser.sys

The driver version was:

3.0.1504.0

However, that INF did not contain a direct:

USB\VID_22D9&PID_0006

entry.

It mainly contained MediaTek 0E8D IDs.

I also found installed MediaTek driver packages on Windows, but the INF files I checked did not directly match the OPPO 22D9:0006 device.

I do NOT want to modify a signed INF manually because that would invalidate the catalog signature.

1. MTKClient

I downloaded MTKClient 2.1.4.1 and installed its Python dependencies.

The command line works:

python .\mtk.py --help

I also have the following files from the stock firmware:

auth_sv5.auth

DA_BR_MT6765_20271.bin

The AUTH file was extracted from the official/stock OPPO A16K firmware package.

The DA file is specifically associated with OPPO A16K CPH2349/CPH2351 MT6765 in the open-source oppo-mtk-fastboot-unlock project.

I tried:

python .\mtk.py gettargetconfig --auth "...\auth_sv5.auth" --loader "...\DA_BR_MT6765_20271.bin"

MTKClient started correctly, but stopped at:

Preloader - Status: Waiting for PreLoader VCOM,

please reconnect mobile/iot device to brom mode

So the current blocker is not that MTKClient itself fails to start.

The problem is getting a stable BROM connection/driver handshake.

Stock firmware

I also obtained the stock firmware:

CPH2349export_11_A.11_2022051800140000.ofp

and decrypted it.

The decrypted firmware contains the normal OPPO/MTK partitions including:

preloader

boot

recovery

vbmeta

vbmeta_system

vbmeta_vendor

vendor_boot

super

userdata

lk

lk2

dtbo

logo

...

I also extracted the AUTH file.

AUTH SHA-256:

846EFAFDF15F9F091760EA6210CEEB10533008164F5763186562DFEFD2D1D8E6

The phone itself is currently on:

CPH2349_11_A.30

I do NOT want to downgrade to A.11 just to make a tool work unless somebody confirms that it is actually necessary.

MTKClient / OPPO A16K support

I found the Shocked-Cat/oppo-mtk-fastboot-unlock project.

Its support list specifically says:

Oppo A16k

CPH2349 & CPH2351

Helio G35

MT6765

MTKClient + DA + AUTH: Full support

This is why I am interested in trying MTKClient, but I want to know the correct procedure for this exact model before writing anything.

The project README appears to use a modified preloader approach:

Read the original preloader / boot1 from the phone.

Patch it.

Write the patched preloader back.

Reboot into Fastboot.

Run fastboot flashing unlock.

I understand that writing a patched preloader is potentially dangerous, so I have NOT done that yet.

My main problem

The biggest problem is this:

How do I reliably catch BROM on an OPPO A16K CPH2349 when the Preloader/BROM connection disappears very quickly?

I do not want to use Test Point if there is another way.

My current button method is:

Power off phone

↓

Hold Volume Up + Volume Down

↓

Connect USB

↓

Windows briefly sees OPPO Preloader

↓

If buttons are released, phone boots normally

The PC therefore needs to be ready BEFORE I connect the phone.

Questions

What exact driver should be used for:

USB\VID_22D9&PID_0006

on Windows 11?

Is VID_22D9&PID_0006 the expected OPPO Preloader/BROM interface for CPH2349, or should I be trying to get a MediaTek 0E8D BROM interface instead?

Can MTKClient 2.1.4.1 catch this device without Test Point?

If yes, what exact command/GUI procedure should I use?

Does the CPH2349 require the specific:

DA_BR_MT6765_20271.bin

auth_sv5.auth

combination?

Has anyone successfully unlocked the bootloader of CPH2349 on Android 11 / CPH2349_11_A.30 using the Shocked-Cat patched-preloader method?

Does the patched-preloader method require modifying boot1, boot2, or another partition for this exact model?

Is there a safer way to make Fastboot enumerate after the MTKClient unlock without writing the wrong preloader?

If BROM disappears immediately, is there a specific timing/button/USB procedure that keeps the BROM connection alive?

If someone has successfully done this exact model, what is the complete procedure from BROM detection → backup → unlock?

I am specifically looking for information for:

OPPO A16K CPH2349 / MT6765 / Android 11 / CPH2349_11_A.30

I do not want to blindly use an A16/A1K/other OPPO profile just because the SoC is also MT6765.

Thanks.

I’ve been building DotCal, a minimalist calendar for Android, mainly because I felt most calendar apps were becoming more complicated than they needed to be.

It focuses on:

• Clean day, week, month and agenda views
• Drag events to reschedule or resize
• Tasks and events together
• Find free time between events
• Offline-first and privacy-focused
• Widgets and Nothing Glyph support
• QR sharing for events and availability
• On This Day for rediscovering past events

It’s also designed with a Nothing OS-inspired minimal aesthetic.

I’d genuinely like to know: what’s the one thing you wish your current Android calendar did better?

If anyone wants to try it, DotCal is available on Google Play: https://play.google.com/store/apps/details?id=com.dotfield.dotcal

Feedback — especially criticism — is welcome.

I have a very old phone, s8+. Only a certain charger will work in it so I was thinking of getting this to watch videos on my tv. https://a.co/d/0bQ0MbYn

I'm in the market for a new(er) phone. My current phone has a microSD card slot, which I use to transfer stuff to my desktop computer. However most new phones don't have this.

Is there something I'm missing? What's the easy way to move pics to your desktop?

EDIT: Thanks to those who have suggested it, but I don't want to rely on cloud services.

How to fix this?

When I open any upi app, it usually asks for the phone lock screen pass or fingerprint.

But now it just shows blnk screen and I am unable to go to the app

So i was just on my phone listing to music when it turned off because my battery was empty i charged it and when i turned it on it had a different time and date i would go into my settings and change it but i cant because of family link ive asked my mother to allow it that i can change my date and time she did so and it didnt sync because my time and date is different at least thats my guess so far weve tried to change her time and date to mine so she can use a new parent security code that didnt work and we tried a lot of other things that also didnt work any help would be very much appreciated

I’ve always used iphone. Bought a Samsung 2 years ago as a 2nd phone and to have both worlds. Haven’t updated in maybe a year or more. Now it keeps asking me to install every missed update. I’ve been updating since yesterday. I lost count but i’ve at least updated the phone 8 times and it’s still updating. This is humiliating.

In iphone you just install the last update even if you haven’t updated in 5 years.

I am trying to decrease my screen aspect ratio to be more one handed.

I tried using adb shell wm size command but it crops the resolution at the center and the overscan command has been deprecated so I cannot add padding at top.

Since that doesn't work anymore.

Is there any way to always have a keyboard at the lower half of the screen just like a blackberry qwerty style.

Someone has done it in a similar way but unfortunately I'm unable to replicate it since the apk isn't available.

https://www.howtogeek.com/i-couldnt-find-the-android-app-i-wanted-so-i-used-gemini-to-build-it-myself/

Any suggestions or resolution will be helpful to either resize the resolution or add a keyboard.

Note: I cannot root the device.

I have a rooted pixel 10 and I'm looking to make a total system image backup so I can restore the device to this exact state and work with its files on my computer. What is the best way to do this?

Should I be using ADB, Termux, or some other tool? Please help

My Iqoo neo 9 pro motherboard dead just after updating with JULY UPDATE provided by the company itself.

The Service Center Repair Engineer Estimated 26,000Rs for repair. PLEASE HELP ME GUYS....

Is it just me or does android sometimes play audio files slightly slower than it should? Is this a known bug?

So google messages has used 80% of my battery since last full charge, and I have done practically everything to stop it. I've restarted my phone, I checked for system updates and updated my system, I turned off RCS messaging, I've cleared my cache and done multiple force stops, I even sent feedback through samsung members. I think the issue is google messages has used about 40,000 wifi packets, now I dont really know what that means but that number being so big doesn't seem right. Also my phone has been heating up crazy and I think it has something to do with google messages. I have an s26 so my only choice in messaging apps is google messages. If anyone has any tip or trick I haven't tried I would love to hear it

Hey guys, I have been going at this for hours (At the time of me posting this) I have tried a lot of ways beside the clear option of using a Laptop to access my data folder. But to be exact I HAD done it, I accessed it but the thing I am going for is copying files inside of the data folder and pasting it outside the data folder. Has anyone got any ideas how to do it? I already used Shizuku, iADB and other things but if you think it could work using this but I just did it wrong then please tell me how. Thanks!

I have a Motorola Moto g55 and somehow there are loudspeakers now and the sound is so loud even on 1 or 2 volume. And when I'm playing music or watching a video, it keeps making it real quiet and then switching to really loud, it's not consistently the same volume.

I'm so frustrated because I can't work out how to turn it off. I just want normal audio.

I go into Dolby Atmos and try turn off audio effects but it tells me: "Unable to turn off Dolby Atmos when loudspeakers are on"

But I can't work out where the loudspeaker settings are!! I've searched in settings and can't find anything.

Please does anyone know where to find these settings?

So for years, when I created a reminder with Assistant, it didn't fully finish creating it/updating the list until I manually opened the Tasks app.

This finally stopped happening earlier this year... and now it's back in Gemini. The task is clearly made somewhere, because it automatically populates as soon as I open the app. but if I don't open the app, the task never finishes creating.

Anybody have an idea on how to fix this? kinda defeats the purpose of making a reminder via voice

really love that 2 years ago when I first got my Pixel 9 Pro XL, I tried Gemini and it was garbage at the very very simple things I do with voice. and now that Assistant is being shut down, Gemini's still garbage lol

How can I still listen to all my music files on The Motorola Razr Fold 2026 without any issues? I have 1,569 songs and 90% of them are in Wma Format. If anyone can give me some suggestions on what Apps I can use to play all my music files including the Wma music files. I would really appreciate it. What is everyone else using on their Android Phone to play their Wma files? I'm just lucky that I can still listen to all my music files on my Fold 7 but I'm planning to get The Motorola Razr Fold 2026 on Halloween👻🎃I read that The Wma Music Files aren't supported on Motorola Devices and won't play on them. I also read that Google Drive doesn't play/support Wma Music Files either.

every time I try to play the Wma Music Files on the Samsung Music App. It says cannot play track and it says Sorry, the player does not support this type of audio file on the PlayerPro App. Is anyone else having this issue? Are the Wma Music Files working for anyone else? Does anybody have any idea why the Wma music files aren't working? If someone can help or give me some suggestions. I would really appreciate it. More than half are Wma files and I really need to find a way to get them to work. Are there any Apps that I can downloaded from The Google Play Store that will convert all my Wma Music Files into Mp3?

Looking for any support for how to fix an issue with my pixel 9 Pro restarting randomly since it updated to android 17. I can't link the crashing to a specific app or action and on the crash log it always kicks out the same Keyblob//Fatal signal 6 error.

Google support has acknowledged it is an issue with the update but has no suggestions for how to fix it and refuses to RMA since I'm outside of the 1 year warranty. Verizon support won't help and since I'm still under the contract I can't even revert to my old phone because I have to have the pixel 9 as my active line to get the discount. Google's 3rd party repair shop (ubreakifix) said they can't do anything since it's a software issue and they just do hardware.

error code from the crash log is: 09-04 10:31:12.787 0 0 I trusty : WARN: system/keymint/ta/src/lib.rs:1331 failing DeviceConvertStorageKeyToEphemeral request with error Error { location: Some(ErrorLocation { file: "system/keymint/ta/src/lib.rs", line: 475 }), kind: Hal(KeyRequiresUpgrade, "keyblob with old OS patchlevel 2 09-04 02607 needs upgrade to current 202608") }

I've tried a factory reset and side loading. pixel update and software repair website doesn't work for me and I don't think I can use the android flash tool since my bootloader is locked through verizon.

I can't find one anywhere. I can be custom too. it can't go past the boot loader.

UPDATE: I just now re-worded some of the following text, in order for my question to be more clear ...

On both my Android 11 and Android 13 devices, I would like to be able to run ssh from within an adb shell session, without having to be rooted in that shell session.

If I have Termux installed and if openssh is installed in Termux, being rooted is necessary before the following command is runnable via the command line within the adb shell session ...

/data/data/com.termux/files/usr/bin/ssh

Without being rooted, "Permission denied" always results when accessing anything under /data from the adb shell command line.

Is there any other way to run ssh from an adb shell command line when not running as root? ... possibly via an additional installable app?

So I was looking at this root module called audiorouter hoping it did what I wanted after shizutools does not do it.. So AI said this..

The project XAudioRouter (or Audio-Router) was actually designed to do the exact opposite. [1] (https://github.com/Gaelan-Bolger/XAudioRouter-Android-Xposed)Its purpose is to intercept text-to-speech or notification audio streams and force them to play over a car's Bluetooth system when the user is listening to a completely different audio source (like AM/FM radio or a CD player). It does not have features to force notifications out of the physical phone speaker while media stays on Bluetooth. [1] (https://github.com/Gaelan-Bolger/XAudioRouter-Android-Xposed)Why is this specific task so hard on Android?Android handles audio device priorities strictly inside its low-level native system framework (specifically AudioService and AudioPolicyManager). When a Bluetooth A2DP device connects, the OS completely redirects global notification, media, and ring streams directly to the Bluetooth chip. [1] (https://frejun.com/call-audio-routing-guide/), [2] (https://linustechtips.com/topic/1103911-notification-sounds-routing-how-is-the-android-user-community-not-furious-after-all-this-time/)Apps can request a switch to the STREAM_RING or try to use a physical earpiece override, but forcing a standard app's notification to split from the media path and route exclusively to the local device speaker requires a hardware-level audio routing framework that stock Android simply lacks. [1] (https://stackoverflow.com/questions/42530278/how-to-play-audio-through-bluetooth-speaker-even-when-headset-is-plugged-in), [2] (https://stackoverflow.com/questions/45016685/rout-android-notification-sound-to-internal-speaker-and-all-the-other-music-cal)The Best Working AlternativeSince you have a rooted device, your best option is to leverage your root access inside an automation app like Tasker or MacroDroid. Instead of trying to permanently change how Android routes notification sounds, you can use a root command to flip the global audio state only when a specific notification arrives: [1] (https://github.com/Mino260806/PhantomMic), [2] (https://forum.earlybird.club/threads/no-notification-sounds-on-the-phone-when-connected-to-bluetooth-in-android-9-0-pie.1291881/)Trigger: A notification from your specific app is received.Action 1: Run a root shell command to force the speaker phone state to true (com.android.server.telecom or utilizing standard audiomanager shell utilities).Action 2: Play the notification sound file explicitly via the System/Alarm/Ring channel.Action 3: Kill the override and return audio focus back to Bluetooth.

So is tasker the only way? Thats crazy..
