Phone won't wake up from lockscreen - Android Q&A, Help & Troubleshooting

Hello!
Is there anyone who can help me?
I have ported MIUI8 rom to my device (MT6755 soc.) from Xiaomi Redmi Note 4 (MT6797) and it boots up, almost everything works, but when I lock the phone, it won't wake up. It's just black screen and i can hear sometimes sounds only.
Does anyone knows how to fix this?

Can anybody help me with this touch lock problem?

I'm using a redmi 3 pro and I'm on MIUI 7.
I only have 1 problem with the OS so far, but it's a huge one.
If the phone is idle for 3 seconds, the phone passively locks itself until I touch the screen to reactivate.
It happens on every app, every screen, and is making it impossible to use.
The status bar disappears top when the lock happens and it comes back after I touch the screen.
The video link below shows what is happening. Can any body help me solve this problem?
For all of the searching I did, it seems like I'm the only one who has encountered this problem.
I would appreciate any help on the matter. Thank you.
Edit: I cannot post links until I post some more, so is there anyway that I can show the youtube video of the phone?
Hello.. What rom do you use?
go to
Settings -> Lock screen & fingerprint -> Sleep .-)

Redmi note 3 lineage OS 14.1 fingerprint / vibrate issue?

I have the standard FPC fingerprint scanner and its a Redmi Note 3 Kate model.
Lately I have noticed that the vibration randomly happens as if it detected a fingerprint at the back even when nothing is touching it. Its not that frequent but once or twice a day.
Another thing seems to be that when phone is not touched in a while (Deep sleep) fingerprint will sometimes not work until you push power button.
Is anyone having same issues?

I can not unlock after sleep.

Help me
I am Japanese and I am not good at English.
Because it translates and writes, it may not be correct English.
I can not unlock after sleep.
The screen lights up with the power button.
But swiping the screen does not react.
In this case it is OK.
case 1
In Recovery Mode (TWRP), I can swipe the screen to unlock even after sleep.
Case 2
I can use it without problems until you sleep or lock after powering on from power off.
However, after locking with sleep or power button, the screen lights, but you can not swipe.
Initialization already done
Reinstalled ROM (Officiak MIUI, CM12 etc)
But it does not fix it
Well, this can be one of two issues:
1. Hardware issue, and a very weird one. Almost one-of-a-kind.
2. What MIUI version have you tried? 8.5.10 MIUI 8? You can also try MIUI 7 or the MIUI 9 beta. Try all of them and see if any of them works.
I tried these ROMs
I have not tried MIUI 7, but have any good signs to try?
miui official HMNote2Global_V8.5.1.0.LHMMIED
xiaomi.eu_multi_HMNote2_7.9.21_v9-5.0.zip
Thank you.

My Redmi Note 2 has the MIUI 8 8.5.1.0 and no problems here. For MIUI 7 you can try 7.3.3.0 and for MIUI 9 have you tried 7.9.15? If not try these ROM versions and report back.
I tried, but the result was Ng.
7.3.3.0 and 7.9.15
Since it is not a software problem (apparently), since when has this issue started appearing? I am suspecting this is a hardware issue. Say everything you know, I will try and understand.
Since returning from sleep in TWRP mode is no problem, I think that it is not a hardware problem.

The problem is that the screen stops responding after sleeping normally after starting normally.
You can use it without problems until the screen goes to sleep.
give up.

same case like me
I have flashing rr 6.0 and cm 13.0 and so on based Android 6.0. But except dinolek lineage worked, other's lock screen touch not work sometimes. It's wired. I don't think it's hardware's issue
Exact same problemfor me too. It's not Touch panel problem. I ordered new Touch panel + LCD + frame replacement. After replace still same issue.
If the device goes to sleep -wake up, touch panel stop working.
After reboot phone works perfectly until it sleeps again.

Lift to wake up feature not working on Redmi note 9 pro

Hello everyone,
The lift to wake up feature on my Redmi Note 9 pro stopped working almost a week after I had bought it. The screen doesn't wake up even when I am continuously keeping the lift to wake up setting ON . Can someone please help me with it. I cannot determine whether it is a hardware issue or a software. Thanks in advance..
A simple reboot should fix it
I tried to reboot it , but it didn't work even after that. Thanks anyway
