suhaib.sid86 , via OnePlus 5T , Oct 28, 2021 : Hi, I use 5t phone and the experience is really good with oxygen os, it's been 5 years I have been using this phone. All the phones have a secure folder in 5t called Lockbox you can store your confidential document ID and other private details so no one can access. Suddenly one day my lockbox entire data has been erased, I never deleted them there was a glitch one I opened it will certainly take time to open first would show as empty and then the data will be seen. But in my case all the folders where empty and some folders deleted not by me it happened automatically. I am not sure if I was hacked I do have avast paid anti virus nothing showed up as a threat. I have no idea how to explain. I think I need to upgrade phone. Does anyone has the same issu as me?
