Grabbed the nougat update via opera VPN last night. Installation was smooth. Also clean my cache via stock recovery.
Everything looks okie so far. The thing I like most about the update is the DPI scaling and the default launcher setting now persists through a restart.
Previously the stock launcher will force itself as the default launcher upon reboot even though I set it to Nova. Now Nova launcher will start up properly after a reboot and I will no longer see the stock launcher.
In OB10, I experienced notification LED worked intermittently. So decided to revert to OB9, all well & smooth. Also, if u dun really use long screenshot, which the app can otherwise be downloaded in store, it's fine to go OOS 4.0.
