Big issue after updatimg to Android 10 for my A70 device (SM-A705FN).
The promximity sensor stopped working, as a result : Auto rotation doesn't work anymore and phone position detection doesn't work: when on a call, when the phone is raised to ear level, screen stays on and doesn't auto screen off as it usually does.
we appreciate the chance to asisst you and we extremely apologize for the inconvenience that you are facing
as a first step we recommend you to try to test your proximity sensor by dialing
* # 0 * # then kindly choose sensors if it did not work then unfortunately service is needed as we recommend you to refer to the nearest authorized service center in your country
Thanks for this advice, I tried what you suggested but the promximity sensor is not even detected. As an extra troubleshooting measure, to ensure that the issue isn't hardware related, I restored the OS to Android 9 on this phone and to the surprise, the sensor worked normally. After that, I updated to Android 10 (using OTA), The same symptoms occured again and the sensor is not detected again !
I have been in touch with other users that are facing the same issue as mine after upgrading their A705FN to Android 10.
So the issue is purely related to the recent Android 10 update.
