I have started facing a strange issue since past few months. Widevine L1 suddenly becomes L3 at the device level. Restarting phone helps to bring it back to L1 temparorily and it changes back to L3 randomly. This has obviously an impact on Netflix, Amazon Prime where I cannot play UHD contents anymore and restarting phone every time is not convenient. Considering a flagship phone, I am surprised that Samsung is neglecting fixes for such basic issues. I am using 'DRM Info' app to check Widevine status. Has anyone faced same issue and knows the solutioon?
