Screen Protectors causing issues
I am posting this as an FYI...
I have been having issues with my phone since installing a screen protector. (Steinheil ultra)
The screen would blank after unlocking. The knock on feature would rarely work. The screen would not come on when I would pull the phone away from my face. Lastly, I installed a proximity sensor app that showed my proximity sensor to be flaky. I'd test by getting my hand near the sensor. When pulling it away, it would take anywhere from 2-30 seconds for the proximity sensor to notice that my hand was not covering the sensor.
I then decided to lift the screen protector and trim the part that was covering the proximity sensor. (This protector had a cutout for the camera but not the sensor). As soon as I trimmed it to expose the sensor, my problems immediately went away.I have not had an issue since.
I've contacted Spigen to notify them about this issue.
Re: Screen Protectors causing issues
Thanks for that! Screen protectors and cases are common causes of blank screen problems after a call. You always need to make sure the proximity sensor isn't being blocked.
