Redmi note 4, 64gb rom - Xiaomi Redmi Note 4 Questions & Answers

Hi Team,
I have the mentioned device with me and it had a problem of not turning ON the screen once turned off..
The exact problem is.
The set normally turns on and able to use by keeping the screen always ON. by selecting
Settings---->Lock Screen---> timer has been set to NEVER.
If once we turns of the screen by pressing the power button to turn off the screen,it turns off normally and if we press the power button again to turn on, it does not turn on .
In this case, we need to start the handset as if we start a new set. I am unable to find the problem.
Mi unlock done, new version flashed successfully using the fastboot rom miui9.0.5.0 and everything went on well. But the said problem still persists.
Request the team to help in this regard.

[Q] Screen is blank - HELP!

Hello, my name is Udi. I have recently bought an ASUS Transformer Prime.
Last night I turned it on, it started loading showing the ASUS icon, and then the screen turned black. The device is working (sounds of E-mails, for example), but the screen is blank. Only some backlight is visible. Touch is working.
I am able to turn it off, after pressing the power button for 2 seconds, by guessing the position of the "yes" when it asks me if I want to turn the device off.
I tried reseting using the power button and the volume down button, but it doesn't work.
HELP ANYONE???

K3 note screen replacement issues

Hello everyone
I replaced my lcd and digitizer because the touch did not working on the original screen of K3 note
I have the following problems
The screen works and touch also when i power up the device but when i lock the screen from power button the screen 8/10 times never turn on and i can see only the backlight, if i press multiple times the power button it will turn on finally but i never know when it will. If i remove the battery and turn it on again , everything works fine until i lock the phone. The phone works when it is locked by the way. Also if i press the power button to unlock the touch works but i can see only the back light no image.
I tried to lock and unlock the screen with gestures , same problem.
The weird think is that sometimes it turns on.
One think i forgot to mention is that sometimes when the screen turn on after pressing the power button i see black horizontal lines for some seconts(flickering) and then they dissapear
I tried a lot of different roms, i disconnected and connected again, never sleep mode with safe locker , i disabled the proximity sensor with x posed , i removed the sd card, nothing helped.
Can anyone suggest me something else to do?
Changing screen settings maybe? and how
Thanks a lot and sorry for my engish it is not my native language.

Strange behavior after dropping the phone

I've just dropped my RN4 and the screen stopped to work (black screen with no backlight) but I could tell that the touch was working well as I've managed to pick up a call. I wanted to remove the SIM card from the tray so I turned the device off by pressing power button for approx. 15s. Then I wanted to back my data up and boot the device to transfer data to the PC however I was unable to - when I've tried to press the power button to turn it on, device vibrated once and is doing so repeatedly from then on (the cycle is: vibration - 10 s pause - vibration-.... you get it). After plugging it into PC it is discovered as unknown device only. Is it matter of broken screen only or some more serious problem?

GS9+ shutdown after unlock the screen

I am on stock ATT rom. Since this morning, every time I unlock the device (I didn't enable pin or fingerprint, just swipe to unlock), it will suddenly turn off within few seconds.
As long as I stay at lock screen, it will not turn off at all. otherwise it will just turn off by itself. There is no notice saying the phone is turning off, It just go directly to black. I can still go to stock android recovery, I can charge it.
Any idea?

The phone actually powers down? Where as you have to hold in the power button to turn it back on?

Black screen but ambient display screen and phone working

It's the third time that my Nord go to black screen and I can't turn off the phone.
The device it's working, music playing and ambient display turn on the screen but when I unlock (auto with face id and finger print) its turn off but have the backlight on.
I can't turn it off to restart, recovery or fastboot.
I tried all commons things: hold power, hold power+volume, unlock and hold power, all during charge,... all the combinations and nothing happens.
The other times is going on by imself, any solutions? If its turn on im going to change the OS automatically
If there is a toolkit to help to restart the phone or something with adb I appreciate the information, I don't have fastboot enabled and I think the bootloader is lock
