Hi Jayce: I can’t find a developer option on my Nexus7 I saw only wireless& Networks wtih wifi, bluetooth, data usage, and more….. next is Device have sound, display , storage , batter, apps and users, Next Personal have location access, security , language& input backup&reset, Next is Account have google , add account, Next is System, have date&time , accessibility, about tablet., Please tell me how can I find the developer option on my Nexus7 version 4.2 Thank you
Hi Pete.
The problem could be that the developer menu is hidden by default.
To enable it, go to the Settings menu and scroll down to “About phone”, tap it, scroll down to “Build number” item. Tap it 7 (seven) times. After that you should be able to see Developers options.
Hope this helps you.

Hi samuel, try to consult someone with Galaxy Nexus then. I have no idea too.
HELP HELP HELP . I TURNED ON DEVELOPER MODE ON MY NEXUS 4 BY TAPPING 7 TIMES ON BUILD NUMBER š HAVE I LOST WARRANTY ? WILL I BE NOT ABLE TO GET FUTURE ANDROID UPDATES ? š I DIDN’T CHANGED ANYTHING IN THERE ;(
No worry, warranty still valid. And still can get future update. You can remove Developer options by factory reset.
Buddy.You can change everything you want on your phone as long as you are on a stock ROM and Unrooted.You can change everything you want in the developers options and you still will have your warranty š
Sigh :):):) thanks a lot š
