Well..
There's some roms for gts5282 and maybe u guys already tried those out.

Amongst them,one of the most lightweight rom is FAKE_SLIMKAT.

This rom is already $mooth enough to use.But if u guys want ur phone more smooth,just do as I say.

First dload the rom from here..

Start ur job...
Flash this rom via cwm 6.0.3 or twrp 2.6.3


Latest Cwm for gts5282 : http://forum.xda-developers.com/gala...alaxy-t3235242


After flashing that rom flash this kernel before reboot.

ZD KERNEL V5 :

Now reboot ur phone.
Setup everything.
Then go to root explorer and go to system/app.
Delete holo launcher hd and holo notifier.
Replace it with ur launcher(whatever u like).
But i recommend u to replace with SecLauncher2 by argha.

Dload launcher from here : http://forum.xda-developers.com/gala...s/mod-t3134511

Now after replacing launcher,delete bloats that u dont want on ur phone.

I deleted gapps(xcept phonesky nd google login service) coz i dont need them.

Now go to recovery and flash this pure performance hd.

Flash this and reboot ur phone.
Now use greenify to freeze apps and save battery/ram.

Credit : To all those guys who dedicating their times to make our phone a little better.

NB : AFTER DOING THIS,MY GTS5282 NEVER USED MORE THAN 220MB RAM,THOUGH I INSTALLED 14 APP WITH 4 BIG GAME ON MY PHONE.
SO,WHY DONT U GIVE IT A TRY...
