OxygenOS14.0.0.802 After the update,the battery drains very quickly. whenusing LTE it is only 4 hours sometimes less. I use auto refresh and a full HD screen. After using the phone for 15 minutes, it heats up quite alot around the processor (upper part) Some times screen touch not working for 1 or 2 seconds Much more heat this update my oneplus 12. After charging my phone I noticed all my contacts were gone.They were definitely there before.The top part of the screen becomes unresponsive frequently.Have to turn off screen and turn back on to fix.Swipe back gesture stops working often.Swiping up on an app will often "freeze" that appin a slightly zoomed out state with the background still scrolling. Have toturn screen off and back on to clear.Tapping on app icons to launch app often does not launchapp.The currently running apps gallery display (swipe up) isjust pure chaos. Tapping on the background to cancel doesn't always work.Swiping left/right often doesn't work. I've noticed that swiping up to close anapp will sometimes cause the app to reappear so that I have to swipe again toclose it.Photos app often opens a blank window.In Firefox the URL popup modal often gets stuck blocking thetop 2/3rds of the screen. Background still scrolls with touch movement.Tapping the search bar on the app drawer will often justflash the background of the bar (tap is registered) but it does not bring upthe keyboard and search screen. Lock screen animation to unlock the phone makes the phonefeel slowBattery drain on ideal and SOT has reduced.Heating which was not there now is present Excess heating while video recording and screen brightnesslowering in just 5 mins of recording.
