2-cannot find the front camera icon so i'm unable to use it anywhere tell me if it needs to be installed by driver or something.

It is not recommended to backup so much data via PC companion.Use MTP connection mode,it should show up internal memory.

I changed the usb connection option on my Xperia z1 to MTP but when i blug in the usb cable the option icon disappears and comes up the usual phone storage again.

I backed up my photos and videos using Sony pc companion i repaired my phone and still vibration and front camera do not work like i have to send the phone back but unfortunately i have no warranty i guess i'll have to use it without vibration and front camera (it is probably broken).

Now i have another question please i want to know how to install apps dirrectly to SD card and move installed apps there. Android 4.4.4

You cannot move apps to SD,it is a restriction from google.

[Sarsour]

My internal storge is full while my SD card is eighty percent free inclouding that i moved all photos and videos there. is it possible that i install an app in my internal storage then move the android/obb/'folder' to SD card/android/obb/'folder' will that work? I also heared that if you root your android 4.4.4 you'll be able to move installed apps to SD card??

Only by rooting you will be able to do that.For rooting,look on XDA devs forum.
