Any experts or authorized persons in one plus please replay for my question
Use oxygen updater app from playstore.
That have any data loss
Just back up your important data on pc/laptop.
But that is not offical
Then backup your data and visit the service center and ask them to update the phone..
In this situation is not time to go out and my service center is 60 km ago
Then do as said..
That is not offical
Your phone js running a very old build and may not get OTA updates.
Try downloading the latest full build from the support page and flashing it directly.
If you are capable of manually updating yourself go here...READ and download the appropriate packages and flash them.
If you want an official update from OnePlus , go to a service center or contact OnePlus support
