Screen goes blank. Very hard to double tap to bring it back.

There's a proximity sensor (located near the front facing camera) that is supposed to detect when your phone is put to your ear, which turns off the screen to prevent accidental touches. Occasionally a screen protector will trick it to think it's blocked, so you can try removing it if you have one installed. If the screen is extra dirty, that too can trigger the sensor.

If those don't work, it could be a software bug, which would be hard to pinpoint and fix without just going the nuclear route and factory resetting the phone. It also could be a hardware problem with the sensor itself, which would require having a shop try to repair it or try making a warranty claim.

This is a "feature" which has been part of the Samsung experience since at least the Note 8. Have tried many things, many threads, and no one has prevented it.

Well , in my case if I take away from ear screen is back on until it times out or if I put back to my ear it goes black again.
This is how mine has always worked as well. If the screen goes back out it's due to your screen timeout settings not because of the calls.

No not the part to the ear , that's the proximity sensor working at that moment, I'm saying if I take away from my ear then it will depend on the screen timeout.

You're correct wasn't implying that. I was agreeing with the part about up to the ear and was also specifying that when not up to my ear about the screen timeout. Just didnt make that real clear I guess

That's how mine functions.

OP if your screen doesn't come back on when you pull the phone away from your ear, then there might be something blocking the proximity sensor (screen protector/case) or it may be faulty.

I'm hoping it's okay to jump in and ask.

I never put phone to my ear. I hold it where I can look at screen. But screen always goes black! Very annoying. So much so I put some card in my iPhone X.

I can't find solution. Hard to believe this is default normal behavior it for me it's been this way for month I've owned S10+.

Screen timeout is 10 minutes, I'd set it for never if I could. Developer Mode is on. But that only affects while charging.
