15.3.A.1.12 Update..Lagging and lagging a lot !!!

[Prabakar]

I had updated to 15.3.A.1.12 a week ago thru SUS. Update went smooth and even had the SD Card removed before the update.

Its been a week and phone has started to lag, and lag a LOT..  

I never faced lagging when it was in 4.1. Please suggest some solution. Should I do factory reset or wipe out cache or uninstall and re-install somethin. 

I am even ready to get the old firmware(not 4,2 A.0.26) installed. I am ok with the 4.1 version.

Help me out!!!

1st see Settings-Apps-Running...what's eating RAM if there is at least 300MB free - then it's ok (it's all depend of how much apps you've got installed).

If that don't help...

...try with SUS

           or PC Companion.

Factory reset won't solve your problem, the update isn't gone, everything else does...

I guarantee you that after each factory reset your experience will be different. I did 3 times factory reset and every time had different bugs.
I red somewhere on this forum that is the best way to uplate is via OTA and i agree.

No need to downgrade just factory reset and wipe out internal memory. Pull Sd card out before procedure.
If that don't do any good repair it via Pc Companion or SUS.
Don't worry,It's gonna be OK.
Cherrs!

my RAM usage was around 720 MB.. i did restart the phone, and guess..for last 2 days its been around 440 MB and the performance is better.

Still it takes 2-3 seconds to get the keyboard up in Messaging/browsers, frequent lag in rendering images... but overall restart did the trick !!
