Some people just don't use the S3 as heavily as others. There's also a chance that you got a bad unit. If it's so bad, complain at Samsung SC. You might get a new unit with less problems.
Also, while the RAM management of the S3 is NOT the best out there, it can be fixed. I'm running swap and am happy what?
One thing you HAVE to know though. The amount of FREE RAM in Android is a useless number. RAM is there to be used. Like I said it doesn't matter if you have ZERO free RAM if you can run many things at once.
Yes, the S3 has issues running many things at once (at least when you use it stock without rooting), but lags? I can say for sure my S2 lags more.
And using something with issues, whining about it having a problem when you CLEARLY DO NOT WANT TO fix it (or at least make it better) with rooting (or going back to Sammy) - is like driving a car on empty, not wanting to fill up petrol, when there's petrol stations all over around you.
Doesn't matter how much you love the car. Whining is NOT GONNA FILL UP YOUR TANK.
i agree, and in this case, he thinks that i nag nag about s3 and don't want to root it, and don't want to fix the problem, and blame on s3's own ram management and bloatwares, yeah, that should do the trick
