Shortly after installing android 15 I noticed the screen activating repeatedly from standby into lock screen. It does that infrequently, but sometimes more than once a minute. I noticed the problem is caused by the flip case, which has magnets in it. Taking the phone out of the case stops the phone from going out of standby mode on its own.
When the phone is in the case, the screen doesn’t activate immediately when I open the flap of the case.
I looked for settings which could help, but I didn’t find any. I tried disabling NFC, but that didn’t work. Neither did resetting the phone to factory settings.
Since the problem with the screen activation is draining the phone’s battery, I’d like to ask if someone knows of a setting or some other solution which solves this problem. Thanks in advance.
I have the exact same problem.
Magnet in the flip cover is triggering the screen to wake up from standby. Problem started after upgrade to Android 15.
Perhaps the hall/proximity sensor is too sensitive or enabled while it shouldn’t. I guess this could be related a feature to automatically unlock when you open the flip case. However, I cannot find a setting to disable this feature.
I have the exact same problem. I own two Fairphone 5 (256 GB). Both were fine before the update to Android 15, but since the update they react to magnetic fields (the screens randomly turn on and off).
Has anyone found a solution yet? I’ve been waiting for a software update from Fairphone to fix this. I’d really prefer not to have to send both FP5s in for repair.
My FP5 has a flip case with magnetic hasp, but I haven’t noticed the problems described above.
In order to have the screen turn off when the case is closed, and turn on when the case is opened, I use an app that implements the proximity sensor. This has continued to function perfectly with A15.
A workaround has now been found for the problem of continuous unlocking. The flip cover has magnets. I removed them. Now the phone works normally and the battery continues to function for longer periods of time, as I was used to. The magnets apparently affect the proper functioning of Android 15 on the Fairphone 5. Hopefully it will be fixed with a new Android update to be able to use magnets again to keep the flip straight.
