I'm thinking of upgrading from Galaxy S5 to Galaxy S7. I've been having some screen issues for a while now, with the screen flickering green or even staying completely black when I wake it, but this only happened at the lowest brightness setting (and it seemed to occur more often when it was particularly cold out). I'm still not sure whether this is software or hardware related; I
have dropped my phone a few times.
It's slowly been getting worse though, with the "minimum" brightness getting higher and higher. At this point, it does the green flicker when I'm just turning the phone on or off (because the screen dims first, I think). I've read reports of others having similar issues too. I think Pokemon Go may have exacerbated the problem because it's caused me to leave the screen on for much longer than usual, even when I'm not actively using the phone.
Today I had a fully black screen twice, and I noticed that the screen was still touch-responsive (I was able to unlock the screen and do some things just from muscle memory) during that time. I don't know if that was the case before, but I never noticed it then. It was very disconcerting.
So yeah... thinking of upgrading. I've been mulling over this for like 2 hours now instead of doing something productive. Well, I guess buying a phone is productive in its own way. Feel free to offer whatever thoughts or advice you may have.
