[Ali_Nour]

Hi, i've got couple of problems after updating to 4.3,they are listed below:

1.when I'm working with 2 or 3 apps(like: walkman,and email or any thing else) battery gets really hot

2.sometime it hangs for a few seconds

3.ram used to be free around 245 but after updating it is just 186 or even less

4.sometimes touch doesn't work for pattern and I have to redraw it

The only problem is firmware made by Sony , if You have firmware ver. 266 then You must know this . The only way to repair Yoor phone is update but ......... there is no update rollout start yet , becouse Sony still roll this .266 full of lag firmware

Hi,

it looks like the newest updates of Chrome are incomptible with JB 4.3 and cause lagging. Plz try this simple solution: disable Chrome updates and reset the browser to factory settings. Restart phone.

Report here how it goes.

Sorry for my bad english, i live in France

I am a new user of this forum so i say hello to everyone

I've upgrated my sp and i've made a big mistake.

It was a very good device with a long stanby time, with a short reaction time, with no bug and no fatal error. I've the chance to use a 4G network.

After upgrading, it is very slow with a lot of stops, many problems with apllications, the battery range is divided by two.

I would return to 4.1.2 but it's no way to do it simply without sending my SP to service.

You have given a link to upgrade the ROM, plese give us a link to downgrade, give us the choose of the OS, it's not difficult for Sony to get this file on line en his site.

This good device, the Xperia SP don't run correctly with 4.3. No problem if you give us a solution to return to 4.1.2

Thank you
