FP 4 proximity sensor

[hoermich]

My wife just got a new FP 4 and the proximity sensor seems not to work correctly. During she is talking to someone the phone calls someone else itself or simply quits the actual call. How can we calibrate the proximity sensor or reduce the touch sensitivity of the display? Thanks for crowd’s help in advance!

There are quite a few threads about this issue:

The quickest help would be to switch of the screen with the power button before holding the phone to your ear, unless it’s configured to end a call.

So the screen doesn’t stay off when she has it near her ear? Maybe this is related:

Proximity sensor goes crazy while calls

Hello to all! I have had an FP4 for just over a month and am very satisfied. Especially the sustainable concept is great. However, I’ve had a problem with the proximity sensor for a few days. First of all, when I use the phone normally (hand-held, not talking on the phone), I don’t have any problems. The problem only occurs when I talk on the phone with the phone to my ear. The problem is that sometimes the screen turns on and the touch function is also activated, even though I hold the phone…

Can you try dialing * # * # 2 8 8 6 # * # * and running the proximity sensor test? Does it work there? Unfortunately I don’t know of any way to manually calibrate the sensor. And yeah, it seems it’s kinda wonky and needs to be fixed:

• Proximity sensor problem FP4
• Proximity sensor goes crazy in sunlight (WhatsApp, Signal, Facebook Messenger, Stock Dialer, WaveUp)
