You can only able to use data with this. 6) It has no update but still it's showing there is an update i attached the ss 7) Developer options last 3 not working properly. Which is theming options. It's not changing anything.
Please backup your data and factory reset your device. This is the best solution to your issues. A lot of users needs to do this when updating from one android version to another. The reason for this is that one or several bugs can occur during the update process. It will be different for everyone depending on which settings and apps you were using in Android 9, this is why we haven't caught those bugs.
