you do not need a taskiller at all, they create a LOT of issues. it was needed with the 2010 Xperias and even with 2011 Xperias running 2.3.2 but not anymore

Any good application that can make memory management on the device more stable and optimised that we can installl on the phone that you can recommend?

I haven't seen anything good nor anything that's worth it so far, I'll let you know

Its been over a month now and once again the phone crashed and went to No boot.

This time had to reload using the SEUS ,

Things I Did before the phone crashed was I had connected phone in MTP mode to the computer to transfer data and I defraged the SD card using the  RAXCO defrager application i removed the cable from the computer and then tried tooperate the phone it hung and then the system crashed and went to no boot mode .

Should I defrag taking out the SD card or can that be performed when the phone is connected to the computer in MTP mode are there any steps needed to follow ?This is increasingly becomming painful and considering buying a new hadset as SONY Is extreamly unreliable.

Please suggest.

Thank you.
