I know there's the popular issue where the phone shows lower signal strength then what it actual has, but I have an entirely different issue where I get 3g/4g bars but it is grey instead of blue and I have no data at all. This happens in places where I clearly should have signal and the phone still varies in 1-4 bars but it's just grey. This is most easily replicated when turning on/off 4g. Is this just because it takes time to connect? If so..then that really sucks because it takes a while and I would like to be able to toggle 4g on and off more frequently to save battery. This has also happened a few times on its own. Other then this issue, I'm fine with all the other issues/bugs I sometimes run into and love this phone.
