weird bug: once phone is locked it cant be unlocked - Xiaomi Mi Note 10 Questions & Answers

Hi, I am facing with a very weird issue. If I locked phone by pressing power button or waiting until time out, the phone can not be unlocked. The phone it self not freezen. If I turn on music, it plays even after screen is locked, I can volune down and up. But the screen is not back on. I have to hold power button to force phone restart. The phone is working fine until screen is off. No application is installed and I have tried to do factory reset. Also, I have tried to enter in safe mode and nothing helps, the result is the same. Maybe somebody had same issue and fixed it. Or could direct me on the right path where should I look. Thanks in advance.

phone shutting down - power button stuck?

I have a Fuze that wants to shutdown all the time. I usually run EnergyRom on it and the slide to shutdown screen keeps popping up. When I run a stock rom on it, it also shuts down, as if someones holding the power button.
has anyone ran into this issue or have any idea how to fix it? I've searched for a while and can't find anything.
thanks!
Opening up the phone enough to get to the point that you can remove the power button itself and clean that area of the phone should fix the problem.
This even helped me on my previous phone where I thought the button was losing sensitivity. After reassembly the button worked beautifully again.
I had the same problem...and then all of a sudden my power button stopped working altogether...its weird because it works fine to turn the phone on, but once it boots it doesnt turn off the screen or bring up the shut down menu or anything
how did you manage to remove it to clean it out?

[Q] How to disable the Volume Rocker!!!

Hey guys, I've had my HTC Desire S for about a month now,
Today I was using it, and the volume kept turning itself up. I turned it back down, and a few seconds later, back up to nothing. Repeated that a few times, and it kept happening.
I played with the volume buttons and they don't feel jammed at all, the vol. up button is clicking fine, doesn't feel stuck or anything. And if that wasn't bad enough, I tried turning my phone off and on, but when turning it on, it still thinks it's held down so it will only boot into recovery mode. so, as a result my phone wont boot up at all....!!!
Is there any solution for this?? can i disable the Volume rocker??? plz help me out guys..........(i have already rooted my phone so warranty is void!!)

Click to expand...
Click to collapse
not sure about the volume rocker but it is possible to unroot & change to s-on for warranty purposes(not sure about the recovery though)
I put my phone inside a box.
That pretty much disabled the volume rocker.

[Q] Black Screen with Power on, Can't do Anything.

So my friend's nexus 5 is turning on but the screen is just staying black, like just the backlight is on. The phone seems to fine, he's getting notifications and everything, however the touchscreen doesn't work either.
The phone is pattern locked and ADB wasn't enabled, is there anything I can do?
Has this happened to anyone else?
Could we back it up and flash it although it's pattern locked and USB debugging wasn't enabled before?
The phone is flashed, but I'm not sure if he has root anymore, it might have been broken by an update.
Any help would be greatly appreciated.
long press the power button, about 20-30 seconds. this will power it off/reboot it.

Nexus 5 - Hardbrick ?

Hey guys,
I need some urgent help.
My Nexus 5 device is not booting. It stucks at the bootlogo then powers off and restarts again.
Normally it wouldnt be hard to fix such an issue but the problem is :
I can't boot into bootloader (bootloader appears for 1 second then phone powers off)
I can't boot into Recovery mode (Recoverymode appears for a second then phone powers off)
I can't get my phone into fastboot mode, - it appears for a few seconds durign the bootloop as an "unknown device", but I am not able to flash a new bootloader/factoryimage.
I tried like every possible option what I can do, but nothign worked for me.
What else can I try since I can' get my phone into fastbootmode?
Bootloader is unlocked
Secureboot is enabled
(from what i can see in these 2 seconds where the bootlaoder pop's up)
Is there a way to recover my nexus5?
Symptoms of broken starter button
Posté depuis Nexus 5 / Miui7 by Miui-France
Remove the motherboard and clean around the power button. When you have cleaned around the power button, quickly press and release the power button using more pressure than normal a few times, try to boot again.
Thanks for the tips!
I never thought that a broken Button could cause this issue.
I will check it as soon as I am home.
But how am I supposed to clean the motherboard, and I don't understand how cleaning the button from the outside
of the case should help to solve this problem.
Can you guys explain it a bit more detailed please? ^^
Are there good and very detailed tutorials for this?
And yes, you ideas definitely make sense because some days earlier when the Nexus5 was still
booting fine, I remember that I sometimes had the issue when I turned of the display with the power button
it instantly turned on again and I had to turn it off like 3-5 times until it really was off (standby).
To clean around the power button, you'll have to disassemble the phone which is not hard to do it you take your time and use the right tools.

I noticed that the issue really was the powerbutton, - however the button was broken and
not repairable by cleaning. To repair the phone I would have to purchase a new motherboard.
In the end I decieded to purchase another phone, just saying that if someone will have the same issue in the future
try to clean first, if that wont help the powerbutton is most likely broken, and this results in a new motherboard-purchase because
the button is not repaireable by hand
The power is replaceable if the damage is confined to the power button itself.

Android 11 suddenly unable to unlock screen via power button or change volume.

Hi, I started having the strangest issue 2 days ago. Phone model is Samsung Galaxy A50.
I have been unable to unlock my phone once I pressed the lock button or if it went to sleep (screen off).
The only way out of the issue is to restart it by pressing volume down and power for 5 seconds. I put the screen timeout to 10mins (which is the maximum). But no long term solution. Whenever the screen turns dark it stays dark. If a call comes in, the phone vibrates (or ring) but any interaction with the phone is impossible. If I play music, the music continues once the screen is off. The sound can be turned up or down, but it's the only thing that can be done.
While the screen is on, changing the volume via the buttons affects the actual volume of the music, but there is no UI indication that the volume changes, no popup nothing.
So all physical buttons are working correctly.
I have trie "reset parameters", I have tried "reset all data" (backed up everything through Smart Switch). It doesn't change a thing. The phone is reset (still on android 11 though, although I bought it on android 10...) but the issue remains.
Now something very interesting :
Just now, I setup Phone Link for windows 10, so that I am able to see and answer texts and phone calls while at the office. Which works, it sort of defeats the purpose of a "cellular" phone but well...
HOWEVER : while my phone is connected to my desktop through Phone Link. I can lock and unlock at will, change volume and see the UI pop up (via the windows interface or directly on the phone, same behaviour) It's basically fixed. I thought it was fixed for good, so I disconnected my phone from Phone Link. The screen went black as before and there was nothing I could do except reconnect it via Windows 10 (then it immediately starts behaving as usual again...).
My guess is it's definitely software. I just don't understand why a factory reset didn't do the trick...
I wanted to try and reset through the bootloader, but I never managed to effectively get into the bootloader (through volume up and power while the phone is off).
I do not recall making any updates or installing anything just before these symptoms occured. I did install a firmware update that was available after these symptoms started but to no avail
Has anybody seen this before ? Thanks in advance
