HI, i just upgraded my arc S to ICS. Quite laggy..is there anything can be done to improve the performance?
Reformat / factory reset once, then it will be better then first run...
Everybody agrees.
After that will still be laggy to make it bettter,
Root it, if dono how google check XDA forum.
After rooting u can delete many bloatwares like google maps, places, gmail, street view and many app u don't need.
Junk apps all u can remove.
if many apps running ur ram go low, low ram = lag phone.
In ICS ur dialer and contacts will lag lag lag like hell.
Sometimes phone will stuck in call, u need remove battery...
I know gingerbread was better...
