Z3 turns OFF itself while talking, taking a photo, video or checking messages.
It will also reboot while just sitting idle.
Major Lint issue on behind the main display

YOU WILL NEED TO TAKE THE PHONE TO A MOBILE SERVICE CENTER OR TO SOMEONE THAT HAS THE KIT TO UNLOCK IT FOR YOU....OR ONLINE www.mobile2mobile.net or www.gsmok.com

try www.mobile2mobile.net or take it to a mobile service center or take it to a person that can unlock them for a small fee....

you need a special software to make the phione ring louder....but it is best to take the phone to a professional mobile shop ad have the techs there raise the volume for you on the phone.

When you are on a call, press "Options" then "Mute Call"

WARNING - DO NOT ATTEMPT THIS IF YOU ARE AT ALL UNSURE, AND DO NOT ATTEMPT THIS IF YOU DO NOT WISH TO RISK VOIDING YOUR WARRENTY!!!!! Turn off your phone, flip up the front panel and place the phone face down on a soft surface. Use a Torx T5 screwdriver/bit (available from some hardware/electronics stores or online) to carefully unscrew the small screws from the reverse of the front panel. Do not loose these!!! If you turn the phone over you should now be able to lift the top of the front cover away from the display, then slide down slightly to free it from the bottom of the display. Be very careful at this point as there is a small ribbon cable connecting the front cover buttons to the rest of the phone!!! This can be unplugged from the display board by carefully lifting it away, you may need to use a small screwdriver to gently lever it up but in my case this was not necessary. Now use a blower brush (available from any good camera shop) to blow away the dust from both the LCD display and the inside of the front cover. Then simply reassemble the phone by following the above instructions in reverse. Voila - dust free Z3!
