Hi  braInDEAD,

Please find the attached picture to find the location of the Proximity sensor on the device.

Samsung A70.JPG

Please try clearing data and cache of the phone/dialer application
Settings>>Apps>> Tap on three dots >> Show system apps >> Phone>>Storage>>Clear data & Clear cache.

If you are still experiencing the issue, please follow below steps:
• Do not cover the proximity/light sensor area with screen accessories, such as a screen protector or stickers. Doing so may cause the sensor to malfunction.
• Using a Samsung-approved screen protector is recommended. Unapproved screen protectors may cause the sensors to malfunction.
• Connectivity problems may occur in the following situations:
– If you attach metallic stickers on the antenna area of the device
– If you attach a device cover made with a metallic material to the device
– If you cover the device’s antenna area with your hands or other objects while using certain features, such as calls or the mobile data connection.

Thanks,
Keagan

Hi BraInDEAD,

 

It seems proximity sensor is getting activated when you take a call or listen to a voicemail. The screen should lights up when you put the phone away, if it does not light up then your phone needs to be reset.

 

Cheers,

Hi Kevin,
Thanx for reply!
Where is the prox sensor located?
I assume when it's covered it shuts off screen.? But that doesn't explain speaker use. With VM, screen blacks out right B4 the option 2 save message regardless of length.
Ì tried both in safe mode & in regular mode.
The common element is the dialer.
Should I MT it's cache? Download another?
Try calling with & w/o wifi?
Thanks again

Hi Keagan & thanks!
I cleared the phone cache (no change) but not data yet bc of potential data loss?
Please advise

I do have a specific (I think) cover for it with a magnetic closing strap just south of power button; it's sealed.
The areas (diagram) of the proximity & light sensors each seem 2 B covered w/ text (clock, battery %, wifi etc.).

Thanks again for reply & diagram

Hi BraInDEAD,

 

Clearing data for Phone/dialer application erase call logs and recent call lists. It doesn't erase any data that is available on the device.

 

Thanks,
Keagan
