S10 5G phone screen dark on call

[Fred Keezer]

If you have the new S10 5G you may have gone through all the forums help tricks to get your call display to stay on while on a call. In the past having your device on a charger allowed it to stay on in dim mode, But with the S10 5G, This doesn't seem to work even with the old appropriate screen settings checked and timeouts maxed. This may be a software glitch that might be solved in future updates but dont count on it. There is an easy work around though. While on a call enable the "Show RTT keyboard" that can be activated entering the ... phone settings menu while on the call and selecting it. (Top right of current display). This will then bring up your call and keyboard on your display and will stay on continuously even allowing you to toggle on and off both speaker and mute functions while on the call. If you dont like the keyboard display, you can also then select "Show Keypad" in the ... menu setting top right of the display.

It could also be due to a bad proximity detector on your phone, a badly-fitting case or a badly-designed screen protector. Anything blocking the proximity detector will blank the screen if you're not on speakerphone.

It does this with or without speaker phone. This particular issue is not the proximity sensor.

Hi, is this when it's to your ear or speakerphone?


Edit...just seen both lol

Try safe mode

S10 is a bit old school now anyway so just upgrade the phone

 

[Fred Keezer]

No, the proximity sensor works fine. This is simply being on a conference call with the handset on the table plugged into a charger, having all the correct settings to keep the display on but it goes dark in 30 sec anyway. If anyone has ever been on extended conference calls, you know you are going in and out of mute constantly and need to have an active display. This is the s10 5g model, not the S10e or + or note

Is your S10 updated to Android 10 yet?
If not you might just be lucky it's resolved when it does get the update

 

[Fred Keezer]

yep. it is. I've already done a factory reset and that is such a pita I'm not doing that again.

Have you gone into diagnostic mode to check that it's 110% not the sensor?
Tried reflashing the phones software even?

Alternatively to download the phone software from somewhere like SamMobile and re-flash using Odin
