ShivaSharma_FcSuQZPSgz , If the issue isn’t resolved, try performing a factory reset. Additionally, if you’re using any work profiles specific to your organization, be aware that updating may cause issues. If that’s the case, you’ll need to remove the work profile before proceeding with the update.
The main issue I suspect is that work profiles operate within their own address space, and the applications are encrypted in such a way that, during an update, the new version may not be able to decrypt these address spaces, apps, and files properly.
From what I’ve observed, performing a factory reset will likely revert the device to an older version (either 2.0 or 3.0, though I’m not certain). In my previous experience, it rolled back to version 2.0. Good luck dude.!!!
