Back arrow on S9+ not working.

[Android Central Question]

If I am on full screen the back arrow bottom left does not work. Some apps, e.g. Amazon Shopping, are set at full screen by default. Others e.g. Chrome, can be set not to full screen and then the arrow works ok.

Never had a problem. But when you force full screen there is a warning that some apps may be wonky with this turned on. Also, it's probably software issue so should be fixable. Do you have screen protector?
