Hi, so I've been using this device for over a year now (got it in June 2018 I think) and it just doesn't work well anymore, Chrome freezes a lot, system isn't smooth in general, Facebook's Messenger doesn't notify me a lot of the times. I can't update to the newest version, I am currently sitting on 11.0.5.0 and it says I am up to date with everything which is clearly not true. What's the best I can do right now? Upgrade to 11.0.9.0 manually, install custom ROM or downgrade to version that actually works properly?
Thanks in advance.
Thanks in advance.
