I’d like to go back to an older system version. Since I did a factory reset (at the suggestion of Republic, and it incidentally did not fix the problem I was having), my phone updated to something new that I don’t like. Besides changing the appearance of many things, it doesn’t perform so well. Up to that point it had never frozen up or needed to be re-started, but since then I have had to do it a number of times, sometimes because it was flashing crazily on its own through programs. When I turn it back on, it can take 1/2 hour and more to start working; it says it is optimizing 175 apps. I do not know where those 175 apps are hiding. I actually have fewer apps on it than I had before. I’ve had Chrome crash and shut down now several times. And one major problem now is that wi-fi doesn’t work when I have bluetooth turned on. That means that I can no longer use my fitness tracker and phone at the same time…which basically means fitness tracker is useless. Is there something I can do, please?
