Not yet. I went through almost all the different aspects and found some nice new exciting stuff.
Like the camera section with different aspects and ways to get new exciting shots.
Noticed new set of ringtones.
Custome notifications, i get notifications in the messages section , no problem, like before
But all my stuff which is basically gmail, whattsapp, phone, contacts and sms all work perfectly.
All my internet stuff, FB and many other forums, all work well.
I did have one local radio site which Sony told me i should reload as the one on the phone crashed.
Did the reload and all fine
I also put the music on and played through a head phone as well as the ph speakers, all fine.
Not to say i wont get a problem later, but as i said i got the first OTA a few weeks ago, and now today another one, a shorter one to full 6.01
I might just be lucky and got a debugged one.
