Hi, have you tried clearing the phones cache not just an app. Have you updated all your other apps. Have you tried making sure apps are being put to sleep that ain't being used.
Yep, I've just posted exactly the same. The restart didn't help but powering off and then turning back on helped a few apps. If not try opening windows and throwing the phone through open window.
I haven't encountered any issues thankfully, I am unsure why you're having problems with May update.
What device do you have?
My only encounter was my phone giving me a overheating warning and not allowing me to use apps but that's probably more my fault rather then my current device or update.
I have actually got a couple of recent warnings of overheating which I forgot about! I haven't used the phone more or less than before. I have a S24 and had Samsung for over 20 years and never had this many issues
