Hi Team 
Ive recently become a proud owner of a nexus 7 and yes i cant put it down but last night i was playing on it and battery life was around 60% and within 5 minutes a red exclamation mark was shown in the battery logo and when i connected it to the mains it wasn't showing signs of re-charging! so i became scared and thought i might have a virus of some sort and reset it.... and still the problem hadn't gone. The battery i believe had charged as it wasn't dying but when i did connect it to the mains it was saying "connect the charger" and the red exclamation mark was still there, battery life was reading '0% - unknown' The problem has seemed to sort itself out but i have a feeling its gonna happen again...? I have read posts from people who have a galaxy phone and not the tablet... they fixed this problem by taking the battery out and putting it in again but this is harder with the tablet as i don't see the battery coming out easily. please guys help me and tell me there's an easy fix and that i don't have to cry haha.
thanks for your help.
