It happens sometimes but is annoying. while opening recent tab on home screen sometimes it gets stuck on the recent tab and i have to swipe up to open another recent tab to back out.
Which theme are you using?
spider theme for 120 rs wallpaper and icon are from free theme name geometry in space
I can't replicate this but you did say it only happens sometimes so maybe this is why. I can PM you with instructions on how to log your device in case it ever happens again
actually i know how to log this but to replicate it you need to open the recent app tab and close it as fast as you can and do it again and again
