Hi there!
I recently bought an Xperia SP and had it unlocked fully so now i can use any SIM.
But it seems that there is a problem: my phone is slow. I only have a handful of apps installed, nothing is programmed or working in the background or Sync is turned off.
I checked the OS and it is still stuck to Android 4.1.2 but the official Sony Mobile website says the latest is 4.3.
Is there an app to help speed up my phone?
Why is my phone not detecting the 4.3 update?
Please advice. Thanks.
Solved! Go to Solution.
Hi gino76ph
yeah it might, once happened when i tried to upgrade my phone using Wifi it had trouble while installing it was not installed fine, so later connected to computer using Broadband and did it, it installed great, when ever any one ask for update, i suggest them to install using broadband(i am not saying it wont work with WIfi, according to me its good to install with broadband), many users find without any issues.
>so in your case, try to do update once again who knows it might fix the issue,make sure you keep backup if you are willing to do it, so you can wait till next update!!

It has been 2 days post-unlocking of my Xperia SP and stillno 4.3 update.
Connected it to my Mac using Bridge and still no update.
Either Sony is not quite clear with the suppose dupdates and are altogether lying.
Hi gino76ph
its better to wait for some time, I know its frustrating, but Sony will not the customers, I have 3 Sony Phones in my home :), give it some time and we see what happens

I uninstalled the updates for chrome and my phone works fine now.
Settings>Apps>Chrome>Uninstall updates.
Thanks a bunch, also shared this with another thread. You will still be able to use chrome but effectively remove the updates to chrome and return it to it's primary version no biggie for me.
