Power Button won't wake up screen sometimes.

[AwildPikachu]

Hello!
After locking the phone, it happens that sometimes the power button won't turn on the display.
The button is still working, because it is possible to start the Flashlight (long press power button) or open the camera app (double tap power button, can hear the sound).
I'm using the latest lineageos 14.1 version.

Does anybody how to fix this?

I installed the official Oxygen OS and still have the same problem.

Faulty display.

I don't think so, because my display got replaced.

You ever thought why everyone else is using Oreo roms without display issues and you can't? Hmm,I see faulty display.

I'm afraid it is a faulty replacement then.

As ridiculous as that may sound i think it's a problem with your button, you will have to desolder this and resolder a new one. I used to have the same problem, button didn't work like 2/10 at first, and that rate kept increasing. With use and tear it kept worsening. I bought soldering iron and replaced the button, it now works freakin' great.

Okay that sounds strange. I can give it a try.

Now that i see this Thread again, it's far more likely that your lcd just died or partially did. Although if it turns on sometimes like your state, "that sometimes the power button won't turn on the display" it may be a bad teared down soldering on either the power button on the lcd pcb. Get it to a repair shop and ask for a check, if you don't mine you cant open your back cover and remove the screws so you let the motherboard pcb exposed, with a high quality picture we should be able to see if the power button is the problem or not.

The whole display part was replaced in a repair shop.

aye, and? Mine was the same, it worsen upon the replacement, and within some days of usage, the flex cable had gotten damaged for good, the oneplus one replacement displays out there are crappy, mostly used, not well maintained, cheap ones, and they are not to be trusted.

I'm using a cheap replacement from ebay that I replaced myself,and I'm yet to see any issues with it.

 

[venu gopal]

most lcd have the problem. i got a lcd thrice now from different manufacturers had the same problem for some extent
digitizer works fine but lcd doesn't have good connection

My Nexus was also sometimes not waking with the power button. A custom ROM flash (Nexus4Ever) worked well, but still had the same problem. Probably related to this I would notice that when the phone did wake it was sometimes taking a few seconds to do it.

After some searching I found a solution under the lineageos forums -- search for BUGBASH-230 (can't post url here because this is a guest reply). Basically, you have to copy (copy them, don't move them) all tzapps files found in system/etc to system/vendor. It worked for me. There's no more delay in waking up and the problem has been gone for a week now. Before the fix it was occurring at least once a day. Try it.

I have same problem with you and this occcurd after change os nougat to Oreo 8.1 on my j7 prime

It's not the display

I have the same issue on my Nexus 7 with 14.1 installed. The mockingbird replies about it being a faulty display or power button are unfounded considering rebooting the device fixes the issue. Only seems to occur when it's been on for a while or has less than 30% battery.

Did anyone ever fix this? I see this on a few versions of Lineage. Disabling the lock screen in System Profiles settings avoids the issue, but then there's no lock screen!

Not The Display, exactly...

Just thought I would throw in my 2 cent observations. I have a Samsung Relay 4G (t699/apexqtmo). It worked flawlessly with its stock software / and official upgrade (I.C.S. & J.B). Once I upgraded to KitKat or Lollipop, the screen backlight would never turn on after waking the device on a single button push. The difference between these versions of android as it relates to waking the device can be found in changes to power management / wake locks code. I am not good enough to figure the ins and outs of this type of programming, but maybe this will give some hacker an idea of how to patch or work around this particular part of the firmware. Thanks!

 

[brandonoh777]

Just upgraded form stock to LineageOS rooted and all....display wake up worked fine b 4 now i have this problem also it will sometimes eventually wake up but takes forever and many button presses

 

[zosdog]

So, if anyone is till wondering about this, here is the information i believe to fix this bug, that is if anyone can integrate the change into CM KitKat and beyond for our sad old Relay. github.com/TeamApexQ/apexq/issues/24. Any chance this could be implemented through an apk?

Because I really don't want to shell out $$$ for an F(x)tec Pro
