Moto E has many problems. Problems I faced with this device are
When I click Lock button then Moto E will switch off Automatically. My device will switch off 10 times daily.
In SimCard panel Simcard will not fit. Simcard will come out from Panel when I remove back panel. I am using microsim only.
SoundBox stops working for some days.
Battery will die fastly.
These are some problems I am facing with Moto E.
