So, if you find an application laggy is not the phone, is the application it self which is badly coded and don't working correctly as it should.
I give you an example, I have Virtua Tennis purchased long time ago, V2.0, then updates after updates the game become laggy as hell, what that mean, that mean updates are ment to improve the application but if they are bad coded they will give you laggy issues, I reverted to v2.0.
At the end I don't think a Firmware will solve all this problems but you can be sure, you will get improvements installing Custom Roms or Custom Kernels which are ment to performing your device.
I don't saying it is worth to unlock bootloader, check also the applications which working in background, all the time they are the main reason for laggy phone as they run and eat ram and CPU.
You have to spend time flashing some latest FW and find the most stable combination.
Thanks for the quick answer!
And what you're saying about the background apps eating ram and cpu, i was thinking the same thing. I notice the lag is random, sometimes it goes quite fluent and sometimes its like i'm working with a phone that can't handle the os because of low specs. Really weird. Is there any tool that gives detailed insight into these background apps and stuff?
The main thing bothering me is the phone/phonebook/call log app which is delivered from sony itself. It's just text, and even that makes the scrolling in that app very stuttery. While i get updates for apps like album, and the scrolling inside that app goes smooth as silk. Just like scrolling within chrome (although it sometimes hangs for a very short moment).
And btw. rooting and deodexing without unlocking the bootloader, will that help too? I guess there's tools that make better performance too then. Or is working with unlocked bootloader better?
