Guys, I've installed googke go, youtube go,maps go, navigation go and files go apps. Then I disabled Google, YouTube and Maps.
Seriously, the device performance has smoothen and battery drain and gliches has been removed. But I've to compromise with the features like Google Assistant and all. But I thought, I really don't use them much so why to bother about that.
Even my memory management also boosted up and got 1.5 GB+ more storage free.
Before, my RAM used to be loaded full and crashes frequently, now this is not an issue. Even app opening time also decreased.
I think, you guys should also try this with your Nokia 3
