Power button problems - Xiaomi Redmi Note 4 Questions & Answers

Sometimes it locks/unlocks phone just by pressing it, but most of the time I have to click 10-20 times for it to work. I've found YouTube videos saying you should reboot phone, but problem persists. Has anyone experienced something similar?

HD2, hanging on unlock

Very annoying problem this, ive only done the ROM update offered by T-mobile to fix some bugs.
Now it will randomly stop responding when you press any button on the phone it doesnt do anything. If you hold down the power button then tap it again sometimes it comes to life. Ive called it when it does this to try and wake it up as it were or send a text, nothing it doesnt even recognise they have been sent after the restart. All i can do is a soft reset. Anyone have a clue what could be causing this?

I have this problem as well. sometimes pressing the power key all that happens is the keys light up but no response on the screen, you may fin dif you leave it a few minutes it will start to work again. I'm not an expert in these things but it seems to be similar to if you have a faulty memory stick in a pc. I'm on my 5th replacement from HTC on just 6 moth of owning the phone. Its a complete nightmare and renders the phone completely useless. Send it to htc for repair. check any return handsets very carefully they send you as they sent me 3 handsets with the screens incorrectly fitted. Take date stamped pics of your handset also before sending so you can prove the condition of it before it was sent to them.

[Q] Phone Does Not Vibrate/Freezes with long End Press.

Hi,
I've been installing and testing various ROMs for my T-Mobile Leo (HD2) before and never had any problems until now. Problem is, after the last flash, I noticed the phone doesn't vibrate any more, I've checked all the settings and even turned vibrate on/off, nothing helps. Also, if I long press the end key to shutdown the phone, it freezes, I then have to press end to lock, wait about 30 seconds then unlock to be able to use again. Important to note, when the phone freezes, only the touch screen freezes, the buttons continue to work, and I can even call the last party or answer/end calls.
I flashed some older firmwares that I used to use that used to work, but these problems still persist.
Is there any way I can diagnose the phone hardware completely? Any program or tool? I live in Guyana, South America so taking it to a repair centre is not an option, basically, I have to fix it myself.
Did I post this in the wrong thread/forum? Why and I not getting any help?
I'm still having this problem and need help! Somebody... any suggestions???

Mate, honestly, I never notice that it would vibrate on long pressing
As long as your phone is working, then you shouldnt worry about it.
Or else, you can try to restore to original stock rom and see if this is due to hardware problem or software problem
I don't mean that it vibrates on long press. I said that it has stopped vibrating AT ALL!
In addition to that, the phone freezes alot, especially when I long press the end key. It is behaving like a hardware problem, that's why I'm asking about diagnostics for the HD2.
I dont think its anything to do with the rom. I had the same problem with mine, what happens is the flash lens gets pushed inside and stops the vibrator from rotating. Just check the lens if u see it pressed, its an easy fix if u know how to take the phone apart. For instruction check out youtube. I hope this helps.

You should probably read back my post... I said the phone stop vibrating... not that it stop vibrating on long end press... It also freezes when I long end press... Hence, the reason I asked for any diagnostics for the HD2 as I suspect it may be hardware related...

This actually seems to be the problem, I will open the phone and check... Thank you so much for your suggestion, I followed this suggestion, and now the touch screen is not working... but the phone is vibrating again. Any ideas what I will have to change now?

Your battery is most likely exhausted. Have you tried charging it up?

Known issue - random black screen of death. I've only had it happen once. You can clear it with adb reboot, I think.
I disabled quick boot after it happened, it's not happened again, but peopel say this isn't a fix.
Thanks.. adb reboot is better than pulling off the battery.May i need to develop some app that would listen to a long key press of power button and restart the watch.

Added to Xposed Additions, both my mod (link in general) and official. (Not sure if it works, have not seen the black screen when I have used this.)
I developed a app that takes a phone no as input.If your watch blacks out , then you call your watch from this phone no and that should restart your omate.

( This would work only for rooted omate watches)

Fatal issue with phones power button

Hey there, I have had no problems with my Z2 until today. My screen is constantly flickering on and off as if the power button is being repeatedly pressed, furthermore the window with the options to power off/ restart etc also appear occasionally. I'm unable to power the device off as when I do it will boot itself up again straight away. As you can imagine, this renders the device utterly useless. Has anyone had a similar experience with this? Or does anyone have any fix suggestions? The phone is out of warranty, I'm unable to replace it.
I made a short video of the problem just in case my explanation isn't clear enough.

Thanks for any help you can offer me.

Have you tried to hard reboot the phone?
If yes, maybe you should think about a factory reset and / or reflashing the ROM..

G5 lag on wake and you tube?

Anyone else experiencing lag on their g5 mine continually struggles to wake sometime needing a good thirty seconds to spring to life?
Also the you tube app continually stutters and freezes up the phone whether connected to fibre broadband or 4g?

Yes, I actually made a solution for it in the Questions forum, but nobody else seemed to have the issue or care. I found that the wake lag occurs when you try to wake too soon after locking.
I found a very strange solution, but it works: Everytime your phone turns on from being off, you must change your lockscreen wallpaper. This can be to anything. You can even set the same one again. This process has to be repeated at every boot, but it completely solved the issue on my Verizon G5.
To test it out, just lock your screen and double tap to unlock immediately. Shouldn't be lag.

Have you also had the problem with the you tube app? I'm Also finding a lot of other apps crash resulting in an error report and restart of the app?

No I haven't, sorry! You may need a factory reset or could have downloaded a bad app, not totally sure.
