Hello, I have a galaxy S7 and it's become almost unusable due to an issue with "split screen view". Every 10 minutes or so it starts opening and closing random things with a message along the lines of "split screen view is not supported". I turned this off in settings months ago but it did nothing, what can I do to fix this? Thanks.
Do you experience these symptoms if you test your device in safe mode? If your phone is misbehaving, it's possible that a third-party app is causing the issue. To figure out what app is acting funny, you can use the Safe Mode feature. In Safe Mode, your phone won't run any third-party apps. This allows you to easily identity and remove the app that may be causing the problem. Give this link a try: https://www.samsung.com/us/support/answer/ANS00062983/
I would also recommend wiping the cache partition on your device. The system cache partition stores temporary system data. It's supposed to allow the system to access apps more quickly and efficiently, but sometimes things get cluttered and outdated, so a periodic cache clearing can help make the system run more smoothly.
