I have an S7 (yes I know it’s old) I still like it and it works - but - something happens about once or twice a month and it starts hanging up whenever a phone call connects and/or an app will get super laggy.
Anyway, reboot fixes it (so far) and nothing else I’ve tried does.
There’s definitely something with these older phones that is like a slow leak and the simple, easy, lasts for weeks fix is to just take 2 minutes for a full “turn it off and back on again”
Plus the overheating when something gets stuck doing a background thing. Reboot reboot.
I plan to use this phone until it dies, reboot stops fixing things, or needed apps are no longer working/supported.
Slack no longer works/supported, but that one I’m just like “oh, noooo” However I expect ones I actually need to start falling off and I’ll be lucky to get a couple more years of use.
My meandering point, some of us are still using Android phones where reboot helps a lot
You should get a full dermatologist check. Especially if you have ever been sunburned.
Get any suspicious or annoying moles removed and biopsied.
I have 4 friends (granted 50+ years old) who have had skin cancers removed in the last year. Many, many stitches on faces, arms, and necks
