Deepakk_s , via OnePlus 7T , May 10, 2021 : Hi, Recently i got update from oneplus for OxygenOS 11. I haven't update my phone to bete update coz I want to try new features of UI but not at a cost of compromising with bugs/unstable ui. I updated my phone to os11, it took around 20-25min but my device got heated very much during and after the process. It took 3-4 hrs to cool down. I have tried switch off/reboot multiple times. I don't know what makes it heat. Finally i got OS11. After 2 days suddenly i got very blurred video on my Netflix & Amazon Prime App while streaming. I have tried by reinstalling all multiple times but no luck. When i have checked DRM app for widewine support. I shocked to see L3 but my device support L1. As I am in Delhi and it was a lockdown so i can't goto service center. So i messaged Oneplus support about the and they replied - we don't have OTA update for this issue.. Please visit service center. I can't understand why it happened. I never rooted my phone. I never unlocked the bootloader. Its lockdown in Delhi. Everything is closed and in home watching videos in SD(i sure it below SD quality) Is anyone also facing same issue. What you have done to resolve this issue without visiting service center.
