Hi, I recently purchased this phone and it's awesome! Rephrase: It WAS awesome. Then, one day, it decided to start crashing. Constantly. I couldn't take pictures and then look at the roll; could run only a very slim selection of apps without failure. Then for some reason, it would attempt to restart itself and freeze on startup. This could only be resolved by removing/replacing the battery. Even then, it would only function well for a couple minutes upon turning it on. I took it back today and exchanged it for a new one. This one was working fine too. Until I plugged it in to charge and it didn't allow me to use while on the charger. It made me miss my old broken one. I like this phone and want to keep it if I can solve these issues. Is it mere coincidence that these phones were both having issues? Or is it something more (i.e. sim, phone itself, something else)? Thanks in advance for any help!
