Why can't I hang up after call?

"Hi Alain,

I suppose you tried it the way they do it in this video: https://youtu.be/hsop-mM1MZk?t=26s

I wasn't able to do it that easy either. It took a little more effort. I placed the phone flat on my hand, screen up, bottom of the phone facing away from me. (After unlocking the blue locks. Note that there is a final click, so make sure the locks are all the way open.) Then with my index and middle finger I grabbed around the bottom of the phone where the blue locks are now (or somewhere you dont block the screen from sliding down) and pressed my other hand flat on the screen and slid the screen down.

Don't apply too much pressure to the screen. Try to use as much surface of your palm as you can. If you have dry hands breathe onto the screen first or even use a rubber glove to have the necessary grip.

That did the trick for me. Hope that helps!

Best,

Jesko"

I had the same problem. I've used the proximity sensor app, under "settings/maintenance" to solve it. It works!!

I also had troubles with my proximity sensor. Some dust was deposited between the screen and the sensor's lens, blowing it with air solved the problem. Thanks for the tip!

"Recali rating the proximity sensor, did the trick!

Thanks for the advice"

"Hey,

Your proximity sensor is damaged. They are light sensitive, and usually near the earpiece on the handset. It may be disconnected or need to be replaced, to resume full functionality. I have circled it in RED. Possibly open and check the connections with this handset."
