Very laggy phone due to a simple live wallpaper on Samsung Galaxy J5

[Pr0Ankit]

Hello,

I have Samsung Galaxy J5, I installed slim live wallpapers in my phone, but they make the system ui and locker lag a lot.. This problem I did not experience in a phone with lower specs and price (Samsung Galaxy Core 2), with 512 mb ram. I have 1.5 GB Ram in J5 but still it lags a lot.. Another thing which I noticed is that, in j5 the same live wallpaper uses about 100 or 150 mb of ram but in my core 2 it uses only 30 to 40 mb of ram.. It might be a cause of lag ? The System UI in J5/J7 (2015) is very laggy. I flashed cm 12.1 in j5 and tried same live wallpaper and it used only 50 or 60 mb of ram and the phone was very very smooth.. no lag at all..
Is ther anyway how to fix this ?

Best Regards,

It all caused by the launcher. I think that touchwiz in lollipop it is not verry good optimized. Try another launcher or update to 6.0 1 and report back the results.
