Dear oneplus team,

I bought oneplus 8 pro (256 gb) near to last diwali (Still not completed one year). Yesterday about 5:30 when i received a call form my friend my phone got hang and neither restarting nor getting any response. Calls are going to my phone but due to phone hanged i can't respond them.

Kindly suggest me good idea. What should i do, either submit my phone to service center or wait for complete battery ruined???
