My Nexus been great since I got it about 3 months ago. On stock KK, unlocked and rooted. But today it just shut down. There was a message on screen but it closed off straight away and I could not read it. Plugged it in thinking the battery was low but on boot it's at 57%. It ran for a few minutes then the message "attach charger " appeared and it shut down again.
So it's plugged in again and I will let it get to 100%.
Is this a known issue ? Does anyone have a similar issue ?
