I just bought the phone yesterday and have the same problem now. Power saver is on. I think this is a software issue regarding the power saver.
Update:
Okay folks, here is how I solved my problem:
Under power saver settings, turn it off, uncheck "Display, reduce screen brightness", turn power saver back on.

A few questions from a newbie...

Hey all - was a regular at Pinstack when I had a BBerry and one of my fellow stackers recommended this site for my new ATT TILT running WM 6...Here goes:
1. Is there any good app out there that will soft reset, power the phone off?
2. My screen light is always on - it dims but is on - how do I get the screen to turn off completly (dark) when not in use?
3. What is the difference between shutting the phone off (in settings), turning the screen off?
Thanks so much,
Hello and welcome to XDA.
1. Is there any good app out there that will soft reset, power the phone off?

Yes, and they can be found HERE. Lots of free applications out there like Auto reset, Reset scheduler etc...choose what suits your need.
2. My screen light is always on - it dims but is on - how do I get the screen to turn off completly (dark) when not in use?

Use the power button to turn your screen off.
3. What is the difference between shutting the phone off (in settings), turning the screen off?

Turning the phone off in Comm Manager puts your phone in Airplane mode, i.e you'll not be able to make of receive calls. Turning the screen off puts the phone into hibernation, you save battery and you can definitely make and receive calls.
Read the WIKI for more info.
Thanks -
much appreciated

Screen not coming on, but a RED LED blinks ones and it vibrates?

Any ideas of what is up with my mates phone please?
Also when it is on charge the orange charging indicator comes on but not the screen?
He said it randomly shut off on mid text
Thanks
a drained battery. when the battery is dead on my phone, it displays the same behaviour (red led, vibrates once and doesn't power on).
the orange led is normal when charging. when charging from power-off state, screen will stay off till you turn it on.
tell your friend to fully change the battery

I thought this too mate, I have left it on charge for a bit and then turned it off and it does the same although this time, the buttons at the bottom have decided to light up?
i'm not sure then. maybe a faulty battery? just a wild guess. has he tried a factory reset? is the phone rooted?

The phone isn't rooted, any idea of how to factory reset without being able to see the screen?
The phone works as normal, eg the volume rocker works and the turn on sound, and button lights, but not the screen? :s faulty screen connection maybe?

oops, hit the thanks button by accident
faulty screen sounds like a possibility. i don't know how you would be able to do anything if the screen is not working.

[Q] Stuck in extreme power saving mode

I switched on extreme power saving mode because I only had 6 percent battery life left and didn't have access to an outlet. Now that I do have it charging, it wont let me disable it. When I click exit it just says Please Wait (been like that for about 20 minutes). Any idea how to fix this?
I am completely stock and unrooted
I've tried shutting down and restarting

Only way i can think of is to reboot to bootloader and factory reset. Plug it in your computer to see if you can save your pics and stuff. If you went to a sprint store that is what they would do.
To get into bootloader power off device hold volume down and the power button. Click hboot then factory reset. That should do it.

Thanks for the response. After about an hour of trying any and everything to get it working I was able to find a way into the power save settings and disable it from there. Not really sure what happened

I was able to get mine greyed out by going into Developer Options and checking the High Performance Mode option. Maybe yours is checked?

How did you get into the power save settings? I wasn't able to when I was stuck in extreme power save mode.

I went to phone, then the menu button, settings, then click the back button on the top right and it will take you into the System Settings

Same thing happened to me I called HTC and we got it into safe mode and when I hit the home button extreme power saving mode pooped up as a homescreen/launcher along with blink feed and nova so I selected nova and no more issues

I'm having the same issue, it's been over an hour stuck like this. I went in through the phone to settings down to the High Performance Mode and nothing. I tried Safe Mode, nothing. I went into the power settings through system settings and the extreme mode was grayed out as well. I can't do anything to get it working.
Any other ideas? HTC had no idea what I was talking about and told me to take it back to Sprint.

This thread saved my life! I hope this gets to HTC and this bug is fixed! It apparently has something to do with the extreme power saving mode replaceing your home screen, and not being able to find and set the defult home screen back be it blink feed, or google now launcher ect.
Get the lastest software update to permanently fix this problem
I also ran into this problem, and was able to fix it permanently by updating the HTC software with the latest Sprint update. I got there by getting into the general setting by back-spacing while in the phone setting (it won't work for other settings). Now when in EPSM window the exit button works as intended (albeit a bit slowly)

I turn the extreme power safe mode on every night when I go to bed, and disable it the next morning. I had been doing it without a problem for 2 months and this morning had this problem as well. And the funny thing is, BlinkFeed is not my home screen. Reboot, nothing. Forced reboot, nothing. Anyways, toggling the extreme power safe mode on and then off did the trick for me as well.

Serious display problem in my k20 pro

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??!?
Have you tried to install full fastboot rom from miui tool
how long u using k20 pro?
have you ever installing any tweaks for the screen?

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.
