Just got the GT-19300 and a little puzzled

[MarcuS_IRL]

Hey guys,

Just got the phone the other day.
Some guy got it as free upgrade on billpay with vodafone but decided to keep his current phone and sell this on so I got it for a great deal.
I unlocked it and changed network and everything is fine EXCEPT.
It's running really slowly for some things, especially dialer, contacts and messages.
It's on 4.1.2 by the way.

I tried resetting to factory, wiping caches, reinstalling update through Kies, resetting to factory, wiping caches again.
Nothing helps.

Seems like a lot of other folks are experiencing this crap since JB switchover from ICS.

Is there any fix for this apart from rooting and installing custom ROM?
Didn't think I'd have to go the the hassle of doing this with such an expensive phone. At times it feels like my old Vodafone 858 smart
Seriously, it can take 4-5 seconds to open contacts, dialer or messages.
Once you open them they open fast after that, until they are released from ram again.

If Samsung are aware of this and are planning an update I will hold out for that, but otherwise, root + modded ROM I reckon, as this feels like a budget phone, not an S3.

This is really crap as I was all excited to finally have a nice , quick , responsive smart phone after well over a year on my old 858 smart.
A little underwhelmed to say the least.

I tried all the fixes like animations to 0.5x and turning off location data etc.. but no difference.
The hardware seems to be fine as it got 15700 I think it was in An tu tu, and everything registered as it should. Seems like hopelessly unoptomised software to me.

Any tips, fixes or suggestions form anyone would be welcomed.

Thanks,

Mark.

Just rooted and installed Wanam lite and it's definitely a lot snappier. Still the problem with the dialer, contacts and message app being dropped from memory after not being used for a while.
Is there a way to edit files to lock the dialer, contacts and message apps to memory permanently?
That would solve the problem.

Cheers,

Mark.

Figured it out with some help.

Installed jk framework and deluxe settings and everything golden now

After a day of using the Wanam lite rom I am happy enough but would like to see if I could get better performance.
Even with this Rom and the JK framework and settings app I still get the occasional bit of lag, especially when using the dialer, and contacts.

Even though with the whitelist checked in JK it seems that the dialer and contacts still get kicked out of ram after a while.

Am interested in finding the smoothest, fastest rom that has instant response with dialer and contacts and also has the latest features.
I don't want to loose any features the phone had by default either.

There are so many roms available and they all claim to be super smooth and fast, so it's hard to know which to use.

I don't want to spend a whole week installing rom after rom.

Would appreciate some feedback from you guys that have tried them all as to which is the smoothest, and is there any that has instant response with dialer and contacts. Hopefully a rom that performance doesn't degrade the longer the phone is running either.

Am I asking for too much or is there such a Rom?

Cheers,

Mark.
