Yes it's laggy, need more fine tuning.

I heard that the Jan update will fix these issues

[Rajshah0041]

Yes, it does need more tuning, there are still some bugs. After deleting the cache partition, it still gets laggy.

Galaxy app booster
Or factory reset(take data backup)

[Rajshah0041]

Yeah, that will be the only last option left for sure.
