I had Revolut on my Redmi Note 8 Pro phone for a while. First when rooted, I used Magisk Hide to get around its security. 2-3 years ago my system started bootlopping and I just went with clean vendor ROM (MIUI) instead. Revolut worked fine on the device until this week. I noticed that it first showed some error that the device can't run the app because of potential security risks, such as rooting, unlocked bootloader, etc. After that it switched to brilliant UX of just showing infinite black screen over and over again. - My phone is **not rooted**. - It still has **unlocked bootloader**. - The ROM is **MIUI Global 12.5.15**. So the only potential culprit is unlocked bootloader, but it has been for years now. I don't want to lock it, nor do anything that causes any sort of data loss. E.g. I know I could go back to root + Magisk Hide, but I don't have time for it now. Revolut support was beyond useless and the only useful thing they told me to do was using some SafetyNet check app, which failed the test, with no details as to why. Other than that, they recommended basic troubleshooting I've already tried, like reinstalling, cache clearing, data clearing, restarting the device, etc. And to lose my data with factory reset, Magisk Hide or anything similar. Other banking apps I have, like mBank and Curve, still work problemlessly BTW. Why did Revolut suddenly decide to cut me off from my money? Is it related to some SafetyNet update? I doubt as it said it's deprecated in the SafetyNet test app? Is there any way to get around it **without losing data of other apps**?

My Redmi 8 phone is in bootloop. It got stuck with its Remi logo and does not start. I am trying to unlock the bootloader but I didn't find a way other than mi unlock which I don't know how to use it without knowing my mi account credentials.

I'm using a Redmi 13C and a M25 earbud, 4 days ago my mom shut it down and hid it away. Find my device from Google doesn't work, I don't enable power on schedule yet why does it still connect to my ear buds Bluetooth?

Overnight, starting from a 100% charge, all apps closed, even from a fresh reboot, screen of course off, my phone (Redmi 6) ends up with a ~90% charge. I know this is abnormal, as my previous phone (Redmi 5A, with worn out battery) ends up with ~99% in the same situation. That's quite annoying to know that *something* needlessly drains my battery! I'm pretty sure it's due to some software bug. Encountering the issue as well on MIUI 10 and 11. I'd like to find out the culprit in order to fix the issue. What can I do?
For the record, my syslog receives the following two errors *a lot* (several per second): BoostFramework() : Exception_1 = java.lang.ClassNotFoundException: com.qualcomm.qti.Performance BoostFramework() Ux Perf : Exception = java.lang.ClassNotFoundException: com.qualcomm.qti.UxPerformance (then, just in case, I went to the Developer options and fully disabled logging, who knows! But it didn't fix the battery issue.)
Also for the record, I have already done a lot of googling about that battery drain issue, and tried the following fix: Go to "Settings > App > Permissions > Autostart" and disable everything (in my case I only had "Camera" enabled). Sadly, it didn't fix the issue.
**Update:** I've had run "Battery usage stats" during the day, and it reported me that the screen was most (like 90~95%, as I recall) using the battery, followed by a few % by the networks (cell, wifi). But here I just looked at "Battery usage stats" and it gave me interesting results: Screen 35%, Cell standby 31%, Wifi 24%… This is something I was also suspecting. It's highly possible the battery drain is caused by network (both cell and wifi) activity, which in turn could be caused by some software bug. Even though I made sure that no apps or widgets are running. What could I do to investigate further this path? Maybe there is some setting (possibly advanced) that could fix the issue?
**Update 2:** As suggested in the comments, I tried "airplane mode" (i.e. cell and wifi networks disabled) and it seems to solve the issue. I think that both, cell and wifi, cause battery drain. However, that adds an annoying handling step, and I cannot receive calls while in airplane mode. I wish I could avoid that extra handling. I usually don't use wifi, so I'll try disabling only wifi and see if it's sufficient. The MediaTek chipset of the Redmi 6 definitely seems to be a bad pick. This chipset forbids almost any custom ROM, and now I discover it's not energy-efficient at all for networks…
**Update 3:** Some feedback after an extensive period of testing. I can keep cell network and mobile data always on, turning the wifi off seems to be sufficient. Overnight, the battery goes down to barely 99%, it reaches 98% at the very worst… sometimes it even stays at 100% :) Coupled with a good mobile plan, I just keep the wifi always off, and no longer think about this issue :)

I recently flashed a custom ROM and rooted my Redmi 7A, and now each time I try to connect to a network from a TP-Link router, it just says "Check password and try again," even though I insert the correct password. Also, before rooting and flashing a custom ROM, it worked just fine, and I have tried multiple ROMs, and it still doesn't work.

Before we start, just want to make it clear that I am aware how easy it is to brick this device, and have decided to go ahead rooting and installing a custom ROM anyway. My goal currently is to use twrp to install magisk and root the phone, but I cannot get the thing to boot into twrp. In case it matters, I'm running Miui 12.0.8.0 Global with Android 10 (4/01/21 patch) on a Global phone. My device is a 6GB/64GB variant with plenty of storage available. I've grabbed the required twrp image from the link in the XDA developers guide (https://forum.xda-developers.com/t/guide-begonia-unlock-bootloader-flash-twrp-and-root-proper.3995919/) as well as a vbmeta image for a Redmi Note 8 because I couldn't find one for the pro variant. I wouldn't expect that's an issue because they run the same OS, but because mine has a mediatek SOC I won't rule it out; if someone has the right vbmeta for me, it would be appreciated. My procedure is as follows: - Boot phone into fastboot, open minimal fastboot/adb from the guide. - Make sure twrp.img and vbmeta.img are in the fastboot directory - fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img - fastboot erase recovery - fastboot flash recovery twrp.img - Hold power and volume up to try to boot recovery. At this point, as long as I keep holding power+vol up the phone will make it to the "REDMI" splash screen, show me the unlocked bootloader icon, and power off. A few seconds later, it will try again to the same result. This will loop indefinitely until I stop holding volume up, at which point it happily boots into Miui; I've let it loop 5 times to be sure. If I hold just vol up (no power) once the phone turns on, like the guide says, it will pass the splash screen and simply shut off. I've tried multiple twrp and vbmeta images to the same result. The next thing to try was to boot directly to the image. I erased recovery, flashed vbmeta, and ran 'fastboot boot twrp.img." The phone hung on the fastboot screen for about 90 seconds before shutting off, and frustratingly then rebooting into *Miui* like nothing happened. If I try to boot to recovery after successfully booting Miui, it works, but I get the stock Xiaomi recovery, which will not help me root my phone. I'm running out of ideas on how to get this thing into the custom recovery. Still a little suspicious it's an AVB related issue, or some form of anti-rollback protection kicking in. Anyone here got any better ideas?

On my friend's Redmi 7A phone, this widget newly appeared on the home screen, probably after a system update. It looks like a little white arc or fingernail clipping on the screen border. Pulling it out shows a circular button with a circle symbol, and tapping that gives the array of buttons in the pic below. We could not identify it in the widget list (homescreen long tap), it cannot be dropped onto the Delete caption, and Google Lens found no instance of my picture. How to get rid of this?

I'm using a Redmi Note 9 Pro (joyeuse) flashed with Xiaomi EU custom ROM and rooted. I bought new earbuds and I noticed I can't have my Bluetooth audio codec as anything but SBC, my new buds should support AAC like most devices In Developers options, I tried switching on HD Audio and switching to AAC or any other codec, but it just switches back to SBC on its own, it's so frustrating, switching to AAC in Bluetooth settings doesn't work either The same thing happened with the last Bluetooth headset I tried. It worked on my PC, and I somehow thought the headset was the problem. My new earbuds face the same issue, and I'm not sure what's causing it. I've used earbuds in the past, and my phone SHOULD have AAC support. Do you have any thoughts? ROM: MIUI 12.5.2 xiaomu.eu custom ROM, Android 11

A Redmi Note 8 got hit and only now we noticed that it's broken. It just reboots into "Redmi-Recovery 3.0" every time I press Reboot > Reboot to System. If possible, we would like to save data on the phone, since there might be our old photos. On some other related post, I saw that "Recovery buttons are Vol. Up + Power, and Vol. Up was stuck". But I think it is not broken on ours, since I can press it to go up. Is it possible to fix it without deleting or saving photos to my PC before wiping?

I've set a scrolling wallpaper, but it only accepted 2/3 of the complete image. I've seen some google apps whose wallpapers are 16:9 aspect ratio and still don't overlap and move from extreme left to extreme right. So how can I do the same with my own wallpaper? And not only the app, If I apply a theme, the wallpaper in that theme also doesn't overlap and moves from extreme left to right. to see what the app is capable of doing, and what happens when I try to do the same with my edited wallpaper. The app in talk is Wallpapers of The Witcher Using Redmi Note 5 Pro. Other specific details of the phone in screenshot included in the above imgur link. First time posting here. I've asked this question at 3 different sites with 0 response. I hope I'll get some answer here. I know what I want is possible as the apps are capable of doing so. Also, I found one question asked before with the same thing asking, but it isn't answered. Coincidentally, the previous asker wanted to apply the same wallpaper that I'm interested in. Thank you. PS: The art is not mine. It is from Deviantart artist astoralexander.

How to root Redmi Pad SE with Magisk (MIUI 14, Android 13)? There are many guides out there, but doing it with boot.img doesn't work. Some of the guides are specific to Redmi Pad SE, but they are really copies where the device name has changed but the instructions are the same for all devices.

I noticed that either USB key or the Razer Kishi gamepad where undetected by my device although it did work some time ago. It may be related to an update or a material problem, I don't know. I tried the devices on both my computer and other android devices and they are perfectly detected. I have no setting to toggle on Settings > Additional Settings, while I saw on the internet that OTG devices have a setting to toggle on for OTG. See attached picture for the specs of my phone. Is there any way to confirm whether it's a software issue or a physical issue ? And would anyone know which steps to take in either case ? EDIT: Extra information provided:

After long discussions with my IT friend He told me about this model.
So I will replace my 9A 2GB RAM with a Poco-M6-Pro 12GB RAM 512GB Dual SIM soon.
My question is do they share the same built-in notes app and can my notes sync over from the 9A to the M6 Pro from Mi-Cloud?

I'm still looking to find a way to export my notes from my Redmi-9A to my PC with all images intact. I recently found out about this program and I'm asking if I log into the cloud with it, can it access my 1000+ synced notes and mass-download them to PC with the notes and the images in them 100% healthy? The program hasn't been updated since 2021 October though according to the site. Program in question: https://miuirom.org/updates/mi-pc-suite Any tips welcome!

I check my screen time through the 'Digital Wellbeing and parental controls' option in the Settings of my MI phone. (Redmi Note 7) I manually calculated today's usage and it's around 2- 2½ hours. However, settings show 10 hr 30 min. I toggled to see the 'hourly' distribution and saw many of the apps being used at 4/5 AM. My phone was switched off during this time and I was asleep. It says I used 4 hr of YouTube today, yet the stats on the YouTube app itself says 30 mins. Is this a common bug? Or should I be concerned?

I wonder whether any Android applications run on MIUI Pad 14 or if some Android applications won't run on it.

I cannot run my favourite MP3 player on my Redmi 11S and Android 13, because the com.google.android.documentsui is missing. How it is possible? App author claims that is an essential system component that must exist, exists by default in Android 11+ and is only gone when user tries to debloat the phone which I personally didn't do. Is there any other reason for com.google.android.documentsui for not existing? Has Redmi removed it intentionally from their Redmi 11S' version of Android? Can Family Link be blocking or removing this file?

I have RedMi 3s (Android 6.0.1) phone. Also, I don't like Google, don't use their email and don't work with a Google account - so I don't use the Google Play Store. For a few years, I have been using the APK Pure app to update all of my other apps. But - a while ago (perhaps early this year?) - somehow, it kind of stopped working. That is, it recognizes the apps that need updates, but never manages to actually get the updates going. So what I'm looking for is another method/venue/app for routinely updating my apps. Preferably - one in which I don't have to actually press "INSTALL" for every single update, but I'm willing to live with that. Alternatively, if I could someone overcome my APK Pure issue, that would be good too. Any ideas? Note: Manually updating individual apps works fine.

I installed an app **LUMEN** that installed a certificate. Ever since the certificate was installed, it is showing that *your secure network maybe monitored or modified* How to remove a certificate Authority installed? Device model: Redmi Note 5

Xiaomi mi max helium with locked bootloader snapdragon 652 from the year 2016. Will it be possible to backup and restore the userdata partition after reinstalling the system? To backup and restore, do you use Qualcomm QFIL and QSTP? Is a special USB cable (deep flash cable) required? Is the firehose.mbn file in the helium.tgz file for installing the ROM via fastboot the only file needed for this? Only with edl-mode using adb reboot edl can I make a backup and restore or is the batteryless and test point method necessary?
