i think the JB 'performance' r vary on different S3 lar ! because some said its good.....some said its less 'ideal' !

nah .... quite smooth la its depend ur usage nia

JB is great esp with Nova, battery drain is abit fast compared to ICS, ram management is clumsy, rubbish apps running wild which is very annoying.

If you've done all the necessary steps without cutting slacks or shortcuts (just because you feel lazy to do it)..you will have a smooth and very pleasant JB experience.
Otherwise..be prepared to battling annoying lags..frequent freeze and force closed apps or any other problematic issue.
Good luck to all of you

so, that means just update OTA is wrong steps?

what is defined as "If you've done all the necessary steps without cutting slacks or shortcuts"

I wonder too....

so far... my phone is still doing ok except for the battery draining issue. a bit regret after doing the update. didn't know it's JB.

after almost one week i update the firmware, what i can observe are:

1. the temperature can easily go up even with light usage.
2. battery drains damn fast. When idling for less than 8 hours also can cost about 15% battery. As a comparison, with ICS, batt dropped around 2-3% after idling for around 10 hours, both with 3G on.
3. charging takes longer time. I did mention before that sometimes even with ICS, the phone even took 2 hours to be charged up to 40%. But that problem can be overcame if you replug the charger again.

But for normal charging, with ICS it usually took maximum 2h15m to fully charge from 20%. With JB, can took up to 30m extra.

4. On screen time, on JB, average i get is less than 2h30m. Very hard to even reach that time. Usage, checked Twitter and Instagram once in an hour, very few texting, one or two short calls, and checked in at one or two places on 4sq.

5. After upgrade, some profile pics in Whatsapp contacts did disappear. But they were reinstalled automatically after a few days.

p/s: i did check if i got install any app that might drink batt juice after i upgraded to JB but got none. Usage after and before upgrade is the same.

Nonetheless, this is what i experienced. I asked my friend he said battery performance so far is slightly better. No high temperature issue also. If the way we do firmware upgrade is also one contributing factor, well, we both did thru KIES.

Just some update to share here. It's quite wrong to advice the users to hold and not upgrade because not all are having the same problems and bugs. But if you ask me, i would say just stay with your ICS as long as you could.

......what u mean by necessary step ?? i did all the upgrade accordingly liao...... got some more to do meh ??

Here is ONE of many cutting slacks that most user do..
* Please do FACTORY RESET after every MAJOR firmware upgrade. (Example : from GB > ICS > JB)
Reason : mostly lazy..feel not necessary..burden..etc..etc

I think most probably ppl reluctant to do it is due to no idea how to backup and restore
everything back to the original state (non root user) after factory reset.

Like i said..decide yourself what you should do.
Dont blame anybody if your JB meet some problematic issue. Most common are lags..freeze..force close..and certain apps not working properly.
If everything works fine..then it's good for you.
If not working fine..then you already knows how to solve it.

Well said

then probably TS can put a note at Main page ^^

Got to agree. Personally it really depends on the user themselves. If you are not that 'jaga' type, seriously you will feel laggy etc.

Only way to really check is when you are a heavy user. At least, thats what i think...

when i want to delete one of the homescreen, touchwiz force close!..haiishhhh!!!

As suggested, factory reset

Guys~~Sorry noob question here~ Is S3 Mini coming to Malaysia??

i have done it before, now have to do it again?

and why my titanium backup cant upload big file to dropbox ?
