I am using yu ao5510 for last two years.. Last month i encountered a problem, my mobile started rebooting itself.. When i went they asked to replace battery from outside.. I did again the problem persists in different manner when i again went to service center they are asking to replace battery again.
When i contacted yu support they also providing hopeless answers.

My friend also ao5510 using last one also had same problem they said same reason after changing battery they said it is complaint. Totally i am not happy with the service and i am disappointed.
