Hi,
My Kaiser has suddenly changed so that when I wake the phone up, I have to unlock the keypad by hitting unlock at bottom left and then unlock again mid way up the screen.
It never used to do this - simply pushing the power button woke up the screen and the keys were no longer locked.
The phone is set so that all keys are locked except the power button - which is what I use to wake the phone up.
Can anybody please suggest what could have changed and how to set it back.
Thanks.
What software did you install lately? Or maybe it was a feature in one of the softwares that you have, and you just enabled it!
All the time, my phone with a CyanogenMod 11 ROM made for D415 model, has a problem turning on the screen. Tapping the power button or home button once doesn't work. Sometimes I have to repeatedly tap the home button many times to turn on the screen if I'm lucky, or if it doesn't turn on at all, I have to reboot it by holding down the power button for so long. Is there a fix for this? Sometimes when I need to use my phone the most, it won't turn on the screen and it's frustrating.
Also, since I have CyanogenMod 11, can I flash a kdz file back to stock 10c/10e or whatever?
When phone has been asleep for a while and I press the power button to wake the phone most times it only wakes after the 3rd or 4th press, any idea why? button is not worn as it works first time when pressing to put phone to sleep, just the awakening that has the issue. And if I put phone to sleep with power button, and then immediately press power button it wakes the phone on first try, but it seems if the phone has been 'asleep' for a while then it takes 3 or 4 attempts to wake phone, not sure why, thanks
does anyone else have this issue?
Cannot just be me surely??
First use a button tester app to make sure is not hardware related. I so also suggest to do a full reset.

Are you on emui? Any deep sleep mods?
Are you rooted?
I've had this when I had AOD on. Could pocket detection be causing it?
Yip think it's some app deep sleep waking issue, will try safe mode and see
When i turn off the display, by double tapping or pressing power button, After that pressing power button again or double tapping wont wake the display on. After a long time period the ambient display might show up but that is becoming rare day by day, every day this period of nightmare is increasing. Now I'm even afraid to turn off the display so that it wont turn on again.
Sometimes when people call, makes the phone rings but shows nothing on the display.
Only way to forcefully wake the display is to pressing power button long time so that it will restart. But nowadays it doesnt even work!!!
Now, Im stuck, is it hardware or software problem??!?

Nope, the fear of uncertain consequences by not properly doing it refrained me to do such(as its my brothers phone).

my Redmi k20 pro display problem
Hi xda developers
After wetting the phone with a hand sanitizer and using the same wetness of the screen, I played the online game and put it in automatic game mode and rested for a while...
After waking up, I noticed that the phone was turned off, which was turned on by holding down the power button, but the screen is off...
Currently, only vibrators and notification lights work for the phone, and the phone is organized by a computer.
Also, the phone is charged and its sound can be heard while connecting it to the charger, and its sound can be heard in the same way to lock the screen.
Does anyone have an idea?
Omg this is what I'm searching for..

I'm also having the exact same problem with my k20 indian variant. Started when I was on miui 11. Thought software issue. Updated to miui 12 still the same. When turn off screen using power button, or time out screen, goes off. After that not able to turn on display by pressing power button or double tap. No AOD , no fingerprint icon. But for some time sound's playing. But sometimes automatically display comes. Sometimes it reboots.
I tried rebooting by pressing and holding power button, the vibration came but no display. But after sometime, display comes. Now almost everytime when display turn off, I'm having this issue. It is really annoying. Have you found a solution? Please update your experience..........

I experienced this problem few months ago. Luckily it was still under warranty and the service center replaced the motherboard for me free of charge.
I have set the fingerprint option to stay on while the display is off option in settings.
I notice that when I turn my display off I get the fingerprint option but when u press it instead of unlocking the device, the screen goes off and does not start for sometime, even when it does it locks the device immediately. I have to press either the power button to get the lock screen again or wait till it goes through the aforementioned process.
My device is on 11.0.3.0 which was updated through the link given for Indian Rom stable update. Has anyone faced this issue?
