xperia sp performance issues after update 4.3

[storm2]

After updating my Xperia SP to android 4.3 i am facing a lot of issues:

1. Ram used to be free around 300MB. But now it is always below 170MB.

2. almost all apps freeze for few seconds and then start running again (Only if I am Lucky enough) or most of the times I have to Force Close them. (And the worst part is within 2 days only after the update "Xperia Home" itself had to be Forced Closed thrice.)

3. Overall performance is sluggish. (It was much better before the update. How can a 1.7GHz Dual core Processor take almost 30 seconds to set a wallpaper...!!!)

4. Sometimes themes dont change sound bar colour. (Its like it depends on their mood.)

5. Today morning screen brightness marker kept dancing as if some ghost was moving the brightness pointer along the brightness bar. (brightness pointer was moving along the bar without even touching it.)

6. Battery life has reduced drastically.

Will all these bugs be fixed in the next update? When will we get a Fix update for these?

I updated my SP to 4.3 and have many problem... Biggest of all was that the top part of screen not woking... try factory reset, not working again, then I reinstal my headset via SUS and my SP working much better, not perfect but much better... dont have any problems with screen... maybe you can try this....

After updating system lags, launcher sometimes needs several seconds to start. Music playback disrupted and so on. Reset telephone, reinstall with sus or pcc doesn't change anything. Sd card (org Sony) with more than 8 GB and my sp stops, screen freze and I have to use the offbutton on the back. Swipe unusable, cause of lags, pls help, make update

I have this problem too...and the unnerving thing is that the Album, Walkman, Device and Movies apps are not working at all, and they repeatedly pop up in the '...has stopped working' message. This are really inconvinient problems, please Sony, find a way to stabilise the update.

My xperia SP is no working smoothly, it takes long time to open the application and wakeup, and some function like light beet is not worked according to setting. it has worked with theme only and while on the call the light beets are continously on mode. application like Albim, Walkman and phonebook and messaging takes too time to open. 

please improve the funtioning of the new oprating system.

Thanking You

well i had performance issues like this simillar, battery draining fast, huge lag but then i dissabled google autosync and sync my phone only once while connected on the charger after day and a half and the performance came back battery life no lag hope this helps to you i guess there will be a fix in the next fw update  

p.s. the only issue i have now it the loosy power button but i guess that is normal

guysz found a way to get u this **bleep**

just install cm11 rom and u'll get 300+mb ram free and the device will be pretty much faster

Turn off Auto Sync as recommended earlier, then install "Synker". Works well for me.
