This causes text manipulation to be significantly bothersome. I believe that this has occurred at least since early Android 11, perhaps since I 1st gained the device. It does not occur on my Pixel 3, even with similar software installed.
I know not how to diagnose it, yet am decently confident that it is caused by Fairphone’s stock ROM. I have tried /e/OS, but do not recall whether it affected that, too. Apologies.
