Hi, Sam.

Good Day.

Thank you so much for your message. 

Again I noticed that after the update to kitkat

it wont allow me to do multitasking like having a call

while playing or texting, or surfing the internet.

But this only happens when I'm in a call. Other than

that its perfect. It seems like all applications are freeze/lock

when i'm in call.

By the way I also noticed that most of the time

my phone randomly flickered a bunch and

then it went dark when i'm turning it on. I've tried some suggestions

I read like holding the power button and the up volume at the same time

but no changes at all.

Thank you so much for your help!

This is odd, please try running the phone in safe mode to see if you get the same problem: http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008

Perfect! It's because of a third party application.Thank you so much! The "safe mode" made my day!

Any suggestions in downloading an application especially some of these are harmfull and can read personal/private informations. I noticed that they can turn on my mobile data, wifi, sync data, camera, sound etc..

Also, what about that  randomly flickered and then it went dark when i'm turning my phone on?

Thanks!

When it comes to downloading third party applications just take notice of the permissions the application is requesting and see if they seem relevant to what the application is supposed to do, for example a live wallpaper is unlikely to need access to your phonebook etc.
