req.
Phone (recommended u unlocking BL)
and the zips.
cause I suspected that was a useless bug on navigation bar since jelly bean till lollipop
and here you go
1st. made sure u go to this link,
https://github.com/gkraynov/nexus-4-navfix <- must be click and read properly... unless u r numb
2nd. read up the steps and check your build number then u go
3rd download and put into fasboots files or you downloaded it into your phone (made sure your phone have unlocked BL with custom recovery like TWRP AND CWM) and enable the development option (u can found on tapping 7x build number)
4th if u on fastboot files
hit this
adb device...
and plug it into PC to recognized it
and till it detected then
follow the links that given (just tired out on fastboot files, its f**king works as well and made sure that code is correctly but I'm not sure lah..) THEN u r done and ensure that u must hit this
adb push update.zip (non-rooted phone will do it and works flawless

)
and altn. way
boot it into recovery and flash the update.zip
reboot
BOOMSHAKALAKA... you're done on this
PS:wrong step and wrong code.. you're gonna to wasted your money on the screen and digitizing panel ya!
