I bought the new Samsung Galaxy S 10.5 tablet, and after a few days I ended up dealing with an adware issue. Along with that, I saw where my menu and back button icons would blink on occasion, about every 30-60 seconds or so. They would blink together for about a half a second. Well, I did a factory reset and then it cleared up. However, now I still have the blinking problem. It's a bit annoying, but tolerable. I was wondering if anyone else was realizing the same problem. I appreciate any advice and help... thanks!
