I've only owned three smartphones. (The first one I didn't even ask for, but now I'm more or less hooked on them.) I don't remember my reason for buying the second one. Oh yeah, now I remember. I didn't buy it, somebody had left it at my mom's work and after a month or so she gave it to me. The screen was cracked and we got it repaired. We also got it unlocked so I could use it with Metro PCS. It was a Galaxy S4. The next one I bought because the Galaxy S4 had a serious bug where it would stop installing any new apps, saying it was out of memory, and it would keep saying that no matter how much memory I freed. I'd have to do a factory reset to get around it, but then it would come up again not too long afterward. Oh wait... no... the first Phone I had had that problem. It was an LG Optimus. The second phone I couldn't turn into a hotspot because that function was permanently disabled for any network other than AT&T. I tried a couple workarounds but none of them worked. That was my sole reason for upgrading to the third phone, which I have now, which is a Galaxy S6. I'm considering getting a new one lately just for 5G. But I'm not sure if 5G is safe. https://blogs.scientificamerican.com/observations/we-have-no-reason-to-believe-5g-is-safe/ Though if it's not, it may be that most of those unsafe radio waves aren't the ones that would be coming from my phone so they're there all around me whether I use 5G or not. Would be nice to know whether that's the case.
