If an Android device is used as intended by the manufacturer, especially its bootloader is not got unlocked or the Android OS is not got rooted, user must NOT fear catching malware ( malicious software ) what refers to any intrusive software developed by cybercriminals ( often called hackers ) to steal data and damage or destroy computers and computer systems. Examples of common malware include viruses, worms, Trojan viruses, spyware, adware, and ransomware.

It is essential to know that most of these apps are also available on Google Play Store. Unfortunately, because of a library of millions of apps, it is pretty challenging for Google to keep the Play Store free of malicious apps.
[General Questions and Answers] StoneCracker:
Yeah, my son is 10. He hasn't modified his phone at all. This isn't malware, it's an app he installed from the play store that opens weblinks at seemingly random times. I'll look through the list and see if he has any of them installed.

Thanks, I'll start taking a look through those.
[Xiaomi Poco F4 GT /  Redmi K50 Gaming] Zecamagrela:
I'm facing an intriguing issue with the battery indicator on my Poco X4 GT cellphone, and I would appreciate some help from the community. Lately, I have noticed that the battery level indicator remains stuck at 15% for hours, regardless of how long I charge the phone. Only when the battery actually drops below 15%, the indicator starts to decrease.

I would like to know if anyone has encountered a similar situation or has any knowledge of possible solutions. If you have experienced something similar or have any suggestions specific to this model, please share your experience or advice.

Additionally, if there are any specific troubleshooting procedures I could follow to resolve this problem or if it is necessary to seek professional technical assistance, I kindly request that you share this information.
[Xiaomi Poco F4 GT /  Redmi K50 Gaming] BR/user:
I have the same problem. what did you do to solve it?
[Xiaomi Poco F4 GT /  Redmi K50 Gaming] ebahim:
Same problem, My battery indicator is dead. With AccuBattery app i see voltage and current and temp of battery remained constant.

Also when phone is power off and plugged to charger battery indicator is constant too, so i guess not bug in android ROM

I don't know if its hardware problem or some thing else like boot loader and how to fix it
[Xiaomi Poco F4 GT /  Redmi K50 Gaming] Zecamagrela:
I managed to solve the problem on my device.

after removing the cover I found that the battery connector was poorly connected, after reconnecting the problem resolved

Thank you, i think this is my solution too

Hello,

I am quite newbie with custom roms and I would like to have some advices about the best rom to choose for note 4x regarding:

- safety / privacy

- stability

I don't need the newest and fanciest functionalities, just something that has been proved to be reliable and safe.

Thanks in advance for your advices
[Xiaomi Redmi 4X Questions & Answers] DataSense:
I think XDA expert should teach us how to build rom from AOSP ourself. Especially after our device (Redmi 4x) already EOL (End-Of-Life). I believe Xiaomi do provide their kernel source code somewhere. It will help us keep our device usable and safety.

[Samsung Galaxy A22 5G] Skyrem22:
Good morning/afternoon everyone, can anybody help me with my problem?

Before this all happened, my phone just randomly shut itself off while I was busy scrolling on facebook then it got stocked at bootloop, following this I formatted the entire phone thru TWRP and even it's internal storage to see if that helps but to no avail. I then flashed the stock rom but still the bootloop persist. I then formatted the phone again then flashed the stock rom alongside the pit file of that rom hoping that it will get rid of the bootloop but still...

I hope everyone can help me, with this. Have a nice day!

Update: While I was writing this post, the phone rebooted thrice then showed the One UI logo then under it it said "Erased" or "Erasing" (I wasn't able to follow it since I'm busy writing this post, TIA)

Edit: So I found out that the /system is missing since when I tried to do a wipe it is non-existent on the choices. and I also checked the stock roms I downloaded and it seems that system.img is nowhere to be found. I don't know, some help will be always appreciated, thank you

Another edit: Still hasn't been resolve yet then I tried to install magisk, the log is as follows:

[Xiaomi Mi 9 Questions & Answers] ggondim:
My girlfriend has a Mi 9 with a broken display months ago. Now Facebook is asking for 2FA but the code is only accessible by this device (she didn't backup the recovery codes).

Long time ago I used USB OTG to control an Xperia Z2 over a mouse.

How could I use a similar solution (USB OTG or a USB hub) to connect the phone to an external display (HDMI or VGA monitor) with a mouse? Can I use any USB-C hub for this?

It's possible to copy Android screen to PC and to use keyboard and mouse from PC instead of the touch screen input on the phone, by using

scrcpy-win64-v2.0

See:

How to Control Your Phone Over PC (Scrcpy) - Xiaomiui.Net

However, you would need to have Developer options, ADB over USB and USB debugging (Security setting) enabled on your phone - if you don't have from earlier, now with the broken screen it's too late to enable them

[Touch Pro, Fuze General] kyphur:
Boy I'm gonna get hammered bad if my search failed to find an existing thread on this one (and yes I will moderate this thread if someone can point me to a relevant thread)...

Just exchanged my first Fuze at 27 days of use because I was experienceing the following issues:

1. Often times when changing bands (i.e. from G/E to 3G or back) it would completely drop the connection.

2. While on a call it wouldn't switch bands.

3. At least once every 36 - 48 hrs it would randomly soft reset.

4. It would lose the Data Connection and not be able to reconnect until I soft reset.

I tried several Radio Roms (Raphael 1.01.25.16, 1.02.25.28, 1..02.25.32 & Experia 1.06.25.29 & Blackstone 1.09.25.14) with the same results.

I used my own Cooked Rom, At&t Stock 1.95.502.5, & Da_G 1.9 w/MSVC again with the same results.

I've also run with & without HardSPL and both Security Locked & Security Unlocked all seems to have no effect on this issue.

So as I said I just exchanged it today. Now on the way back to my office the replacement did a random soft reset!

Has anyone else seen or experienced this issue?
[Touch Pro, Fuze General] KD8DNS:
I'm going to go out on a limb here. Have you replaced your SIM card since this issue has started.
[Touch Pro, Fuze General] kyphur:
Actually I didn't think to do that as my SIM was replaced just a few months ago when I acquired my last (4th) Tilt.

I'll stop at At&t Corp Store on the way home and get a new SIM....
[Touch Pro, Fuze General] KD8DNS:
Actually there is a new sim card, with better band selection. The new sim card was released for the multiband switching issue known with PDA's. Your issue sounds like many I have seen in the field. Especially with the Fuze. This stand most true for people in the 3g/edge border that consistently switching back and forth.

Here is a pic of the sim, make sure they give you this one. not the old blue and white one.
[Touch Pro, Fuze General] kyphur:
Well, the local store didn't have the orange SIMs but they did have one newer than the one I was already using.

Don't know what the numbers mean but I noticed your pic has 71247D, 2024 just to the side of the SIM and mine has 71234G, 3022 there.

I'll just give it a few days and see if things are better. If now then I'll call customer service and insist they ship me an orange SIM.
[Touch Pro, Fuze General] mindfrost82:
The 71234G 3022 one is the same one they shipped me when I got my Fuze (like 2 days after it came out).

I haven't even activated that one, instead I just stuck in my old Cingular branded SIM and it seems to be working alright.

I'll get dropped calls and stuff, but I don't think its related to the SIM.

I contacted AT&T when I got my Fuze and they said there's no real reason for me to swap SIMs and I could just keep that one as a backup, so that's what I've done.
[Touch Pro, Fuze General] KD8DNS:
You should be ok with the one you have, now if you need the newer orange one and they want to charge you p.m. me and ill ship you one no charge. just let me know if the sim fixed the issue. Effectively you still the old sim.

71234 is the SKU for the old sim card.

71247 is the SKU for the new one.
[Touch Pro, Fuze General] KD8DNS:
Does the cingular sim say 3G on it. If not use the AT&T sim.

There have been NUMEROUS network upgrades since the days of the cingular sim, and those sim's are not provisioned for the updates. So if you are getting numerous amounts of dropped calls then you need a new sim card
[Touch Pro, Fuze General] ITNV:
This is great info, thanks! I've had some more dropped calls than usual lately and was thinking about flashing a new radio. I think I'll try the new SIM first!
[Touch Pro, Fuze General] P1Tater:
LMAO:D......

Even moderators don't use the "Search" anymore. What's next?

All joking aside, mine has been doing the same lately. I figured it was my crappy "cooking". Actually, it could be both.:D Was thinking of returning mine as well because of the random resets. Things that make you go hmmmmmm!

Where is my new sim card? I see how it is. Holding out on everyone huh?:p
[Touch Pro, Fuze General] KD8DNS:
You stood me up the other night at the hotel, man I had the donkey's a webcam and a 55 gallon ok KY jelly, so go buy your own damn sim card.:D

Seriously, if you cant get a free one, hit me up and ill take care of ya sweety.
[Touch Pro, Fuze General] mindfrost82:
I've been getting lots of dropped calls lately, no matter which radio I try!!!

I PMed you.

The Cingular SIM I have does say 3G in small print on the back, and the numbers on it are 64205G 3020
[Touch Pro, Fuze General] alabij:
Same with me. Everynow and then the only way to get online is by a soft-reset. I notice it after I've left my phone idle for a while. I got my Fuze in November it came with a blue and white SIM with an orange 3g logo and ATT written in white.
[Touch Pro, Fuze General] mindfrost82:
That's the one mine came with but I haven't been using it, I've been using a really old Cingular branded SIM.

I'm going to switch to the blue/white one though to see if it helps with my dropped calls. If not, I'm going to go to the store to see about the new orange one.
[Touch Pro, Fuze General] kyphur:
Okay I've still experienced all problems with the new blue one. I called CS and they have shipped me an Orange SIM.
[Touch Pro, Fuze General] KD8DNS:
Man, I really would have thought a sim swap would have fixed the issue. I can see one bad fuze, but two in a row doing the exact same thing. Thats a serious issue. Im really hoping that the new orange one fixes the issue. I, from a technical aspect can understand why this is happening and that is what this new SIM is supposed to correct. Lets hope!!
[Touch Pro, Fuze General] P1Tater:
Going to get my orange SIM in about 30 minutes. I'll test and report back.
[Touch Pro, Fuze General] dexjaz:
I just picked up a new SIM card (71247D) to replace my old Cingular 3g 8525 card, and as I was driving back from the AT&T store, my phone dropped a call 3 times! Do I have to wait a period of time before AT&T's network or the phone provisions itself for the card & services? If not, then the new card seems to be no better than my old one.

In addition, my 8525 dropped plenty of calls, while an old Blackberry, like the 8700g was flawless in phone quality in the same areas. I am in Phoenix in 1900 PCS.
[Touch Pro, Fuze General] KD8DNS:
It can take up to an hour for all the data provisioning to be burnt to the sim. Usually right out the store just the phone side is active.
[Touch Pro, Fuze General] P1Tater:
OK, had my new sim card for a little over an hour. No dropped calls so far. I also don't know hwo or why but I have 2 more bars of 3G now. Before I never got above 2 bars of 3G. Now I have 3 bars minimum but mostly 4 bars. It's a little too early to find out about the random resets, but so far so good. Thanks for the heads up. Fingers crossed.
[Android Head-Units] Andreas384:
Hello, recently bought this android head unit on Aliexpress https://a.aliexpress.com/_mLVnBfm . It is the "8G 128G CAM" option.

The radio was pretty good and working fine for a few days, but some problems started after performing the updates which were available through the radio's update app. I noticed that there was also an android update available though the general settings tab.

I tried to install the android update hoping that this could fix the problems. The update was downloaded ok and started to install. After the unit was restarted it was stuck in the android logo sceen and not it keeps restarting all the time (see video) . The radio cannot boot anymore.

I tried all options that I could find in the internet, to try to boot the unit into recovery mode using the RST button in front of the radio screen. Nothing seems to work on this model.

Contacted the seller to advice me how to get into recovery mode and also if I can find the original firmware somewhere. Also to tell me the model name of the radio, maybe I can find something in the internet myself. He doesn't seem have answers to these questions and he offered to send a replacement motherboard. I am pretty sure this can be fixed if we find the way to get into recovery mode and find the original firmware somewhere.

Does anybody facing the same issue, or have some information on how to fix this problem?

Thanks!
[Android Head-Units] Andreas384:
Here are some photos of the mainboard. Can anyone help to identify the model and suggest how to get into recovery and where to find original firmware?
[Android Head-Units] Ricardoblb:
Multimida of the same model as mine, despite having been bought in another store, the same happened to me, after the update it went into a boot loop. So far I haven't found how to enter recovery, not even the firmware and the seller doesn't send the firmware either, it seems he doesn't have it.

The rear side of the unit and connector locations look exactly the same as ours and is also KC97_X20. Got some screenshots at 0:11, 7:11 and 15:02 . Head unit is called KTE KC97 and it seems that it uses the MT6797 (Mediatek Helio X20 ??). Maybe this can help somewhere.

I need to check it on my HU, but if this is a Mediatek Heilo x20, here is the image:

it looks like it supports fastboot method which can help you re-flash it through adb..

try to look into this one: https://source.android.com/docs/setup/build/running

in any case, it looks like they are working on it, a few days ago this website wasn't exists:

Thanks everyone for all your help!

Have opened a case in aliexpress, seller will probably send a new motherboard. Once I receive new board and hopefully headunit will be working, can try and make a backup of the original firmware and post it here if someone has instructions on how to do it on this headunit.

In the meantime, if someone has a compatible firmware again with instructions on how to enter into recovery mode using the RST button, or flash the firmware using another way, can try to do it on the old motherboard and post results here

Hey guys, I was having the bootloop issue. One day I left the car without battery during all night. The following day I have re-connect it and after many loops it entered the unit. Then after turning the car on/off it went back again to the bootloop. I did this twice. So I bought a 12v source to hook up everything outside the car, left it many hours cycling after it accessed, after that it worked always.

Hope it helps
