My blackberry 9790 is acting very weirdly. When i charge my phone,it would increase by large amounts or just skip too 100% charge,however when i stop charging it,and use it for a few minutes,the charge will start dropping rapidly will usually go to yellow but sometimes red and shut off my radio use. I replaced the battery but that didn't solve the problem. Also my blackberry will restart multiple times a day. Usually its in my pocket and im just sitting there,i take it out and its restarting. Is there a software problem or something that i need to know about? Please help
