Stop me before I don't know what I don't know: G5 plus Windows 11

[UTUSN]

So last week my A20 Galaxy *froze* for about ten minutes. Natcherly, I didn't know what was happening & did the usual panic thing.

So I tried the Off/Reset/whatever thing & nothing worked. Finally after 10 minutes things got back to normal?

Then I called Tech "support" - and they went through some whatever & no answers - my QUESTION being: Is it a BATTERY problem or do I need a new PHONE?

So next day at an outlet, they said my model is a little "old," and showed me two 4G ($70) and one 5G ($230). Round and round whether my memory was shot or whether photos removal would help (no), and it's (sort of) working, and also my brilliant question whether 5G is the future, so... (answer, yes)

Might as well take the leap, no?

*** Windows 11 - Of course, I've resisted for a year or more. My elder sister bought a new laptop with Win 11 installed. So going on the postulate that what's-coming-is-coming, I should download the insistent reminders to do it?
