Hi to all, i have been using note 2 (not rooted) for past 1 year and i'm happy about it. But recently i have faced an unexceptional problem , a few days back i was testing google camera app, i was testing different modes for example panaroma mode and when my cell was processing the image it's screen suddenly went black and it started booting up, i was amazed but then i thought it must have been some issue with the software But my phone got stuck on the booting loop, as soon as the samsung logo appears it starts the whole booting procedure again. i tried different things but nothing helped.( i have two batteries) so i replaced the one which i was using during that session with the other one and now this time my phone booted up properly, then i charged the culprit battery in external note 2 charging kit ,normally it takes 3 hours but this time it took 6 hours for the complete charging ,when i again tried with the culprit battery my phone got stuck again in the boot loop since that day i have been trying to boot my phone with that battery but nothing has helped .. while my phone is working and booting properly on the spare battery so kindly help whats wrong with the battery.
