NOOSHITH_satish , via OnePlus 7 Pro , Jun 16, 2021 : Dear OnePlus, Im writting this thread regarding so many hardware and software issues after upgrading to android 11. According to my experience after upgrading to Android 11 my phone heats up, battery drain,and so many lag issues Issues:- 1.gallery loading 2.Battery drain 3.removing widevine L1 support 4.Sometimes message notifications are not shown 5. Lag issues 6.phone strucks sometimes 7.Ram management not good 8. Cropping of images taking long time So I request you to release the update after checking don't blindly release the updates that may impact our day to work . Providing good specs to phone is not enough giving software optimization is more enough.
