I ve already done two things
Nova launcher is the default launcher n its best no doubt
I installed gl tools n also greenifyed fb, msngr etc now phone is lagging less but games r still lagging
N I know nothing about seeder will you plz post the link
Sent from my GT-S5282 using xda premium
I have edited my gltools post for better speed...
and u can find pure graphics hd in my signature below
seeder can be found on play store
or here at xda apps section
most high end games will lag as expected but the games you mentioned shoudnt maybe somethings taking a lot of resources in ur fone
sometimes when i install a lot of apps i find this problem that some app is misbehaving though finding it is quite difficult
when u remove it the fone becomes normal again
except seeder u may also use ram manager
