New Delhi, Delhi, 110017

Sir/mam, i am using redmi note 3 for past 2 months but suddenly i have noticed that my phone's turning off every day for 5-6 times without any reason, everything is working fine, i have not installed any heavy app. Out of 3gb ram, 1.4 gb ram is free. There is no issue regarding ram or battery. Please let me know what is the exact issue and its solution, as quickly as possible. Is this issue related to bug or is it a software issue, whatever the issue is, please fix it in your update..
