GO FULL SCREEN IN MIUI AND REMOVE THE NAVIGATION BAR WITHOUT ANY FLASHING

         Did you just installed miii and got the awesome ui but the bottom navigation bar spoiling your fun?

         well there ate lots of zip files available all around to flash and get rid of it but how will you find the right one? if you flash wrong file your phone wont work and it will give an error saying "SYSTEM UI HAVE STOPPED WORKING". well i did that mistaked and was sick of flashing miii again and flashing different files again and again so i myself found a simple sollution for you guys so lets start the tutorial
         first thing you will need is root explorer so go ahead get it from playstore if you dont mind payng or else google is your friend you can search a little and get the apk and then install it and now fire it

           now in root explorer go to system folder by scrolling down

         now you will see a file called "BUILD.PROP" now hold on it and select "OPEN WITH TEXT EDITOR" like shown below

         now a text document will open in that make sure you dont change any text just carefully scroll to the bottom and type "QEMU.HW.MAINKEYS=1" make sure you type it exactly without any spelling mistakes and once done hit the option key and click save and exit. now restart your phone

          once restarted your phone you will get awesome full screen ui and the navigation bar is no more

well thats all for now guys see ya later with another tutorial and review of miui on galaxy grand.
