[AC Question]

tried to start voice command , now cant get any response from icons
tried several hard reboots

Welcome to Android Central! What voice command feature are you referring to? From Google Now? Which icons aren't responding--the app shortcuts on the homescreen? Or the soft buttons (Home, Back, Recent Apps)? Are you otherwise able to swipe between homescreens?

When you say "hard reboot," do you mean powering down and powering up again? Or a factory reset? Try booting into Recovery Mode and wiping the system cache partition. Bear in mind that this can take up to 10 minutes on the N5: http://forums.androidcentral.com/nex...-recovery.html

thought it said google voice
cannot scroll between screens
no aps will open on home screen, yahoo mail, phone, hangouts
how do I boot into recovery mode
thks

[Gordychap]

I got into recovery mode but cant proceed
it has a green emblem but with a red exclamation sign
then went off and back to home screen, no different

[B. Diddy]

Are you following the steps exactly? When you see the Android on its back with the red exclamation sign, you have to press and hold Power, and then while holding Power, press Volume Up briefly​, then release both.

ok did cache clean and still no better

[B. Diddy]

So the screen doesn't register any touches? It might be a hardware failure. Can you clarify what it was again that you were trying to do when this happened? Voice commands? Google Voice? Those two are very different.

I must of been in google voice cuz now wen tap icon it says what it is

[Gordychap]

ok figured it out
when in talkback caused all problems
ok now
thks

Great! If you never have any use for Talkback (which is more for the visually impaired), then you can disable it by going to Settings>Apps>All​, selecting Talkback, and tapping Disable.
