The problems with my first smartphone (Microsoft lumia 650) have now become a headache. The phone is frequently restarting and battery life is very low. Not only that, the phone is powered by power bank all the time. No update is currently available. Now whats app and facebook are dead. The only quality of this phone is the camera quality and the display.
Now i am wondering why you bought this phone for a penny. I bought this phone for a modest salary of rs 14, 999. You couldn't keep any promise you made when you bought the phone. Please return my phone and give me another phone.
