I have xperia SP recently bought few weeks back. I have upgraded my android to 4.3.
There are many bugs after updating like it hangs quite a lot, some random advertisements are coming over the screen
etc. The recent annoying bug I found on this phone is, it locks the device saying some McAfee device lock screen after removing the SIM. And when I enter the PIN to unlock it, I never get any unlock key on my screen becauze of the keyboard. I can not scroll it, I can not turn the device off (by pressing the power button), when i tried to minimize the keypad it just swapped numeric key and alphnumeric keys. In sort I can not do anything with the phone.
