[Q] Screen lights up slow after unlocking

[ithinkurdumb]

The back of my 920 was making some squeaky sounds so I exchanged for a new one. Everything's great except the screen seems to light up much slower when I pressed the power/unlock button. It takes about 2 seconds after pressing the key until the screen lights up. I don't have another 920 for comparison, but my 720 lights up almost immediately after unlocking.

Could someone with a 920 in hand check how long it takes for the screen to light up after unlocking? Should I have this one exchanged as well? Thanks!

Try switching from auto brightness to full brightness and see if it still does it. Sounds like there may be dust or something in front of the sensor so it takes longer for the phone to realize the light level.

My 920 doesn't have any delay when you unlock it

That must be it! When I set the brightness level to manual, it lights up immediately, and the delay is back when I set the brightness to automatic.

Is it something I can clean myself or should I just exchange for a new one? (just got it yesterday).

Mine is on auto bright and it lights right up

It is probably the infamous dust in the front camera issue earlier models had. If you are comfortable at taking it apart you can clean it yourself. Otherwise I would get it exchanged.:good:

I dunno if it's caused by dust near the proximity/AL sensors. I used some compressed air and made no difference. Also I remember reading somewhere Nokia already fixed the issue on newer 920s.

Ended up getting a replacement. Thanks for everyone who helped!

I got mine about a week ago. It takes a little under a second to light up after pressing the button. This is on autobrightness.(will try manual later when I have time) Does that classify as "instant" ?

On manual its slightly faster, enough to notice the difference, but still not 100% instant. but my guess is I can classify it as instant anyway.
