Hi , I was also on Beta 4 but was not able to sideload beta 5 or beta 6, now when i was checking for stable update, it was showing no update available or you are up to date. So i have manually installed stable OneUi 7 few mins ago on my phone seamles...
if you have completed one year period of buying phone ..then its good otherwise bad.....but remember there is risk to install recovery and custom ROM...i will suggest you to use your current phone version......if you want new system updates regularel...
