Since this morning, my touchscreen does not react anymore
I tried following steps, one by one :
- Phone reboot
- Remove tempered glass
- Remove SD card (SanDisk Extreme 128 GB)
- Factory reset (mouse connected with USB-OTG cable from my work)
- Remove SIM card (Sosh / Orange France)
- Suggested by @Antoine: disconnect screen and reconnect it again
EDIT: FINAL SOLUTION WAS TO PROCEED TO STANDARD EXCHANGE (2-YEAR WARRANTY), AS PROPOSED BY LOCAL RESELLER
My Fairphone 4 has the last firmware update (Fairphone OS v.107 - Build number FP3T.A.107.20220316).
EDIT: almost the last update, see Software update: FP3V.A.0116 update - Discuss / The Products - Fairphone Community Forum
Do you have some ideas? (I do not really want to use it with a mouse )
I think I am dealing with a hardware issue, as even a factory reset is not enough.
I am really sad because after just 1 mounth of use, I personnally think that FP4 is awesome!
Thanks in advance for your help and best regards, Emmanuel
