Two months back i went through the crazy times with my bricked bold 4, Now i have come back home to my home country and gave the phone for warranty, so they replaced the phone and give me a new phone. Now this new phone is already showing really bad signs, First is the battery gets really hot randomly at any time, Noticed this 2-3 times today. Secondly i was logging into twitter and the phone just restarted. Also the phone has been acting a bit slow sometimes. What can i do ?
I would update the OS to the latest one. As far as the battery getting hot, mine does the same thing sometimes during use (mainly phone calls I think). If yours gets hot while your not using it, that would be a concern.
