I bought LG F5 with android 4.1 2 week ago, i use google voice search every day .
Until 3 days ago, i showed "can't reach google at this moment" , even i try my 3g or wifi online it does't work, then recovered the OS still failure.
Now i download ifly voice input , it works, but seems google voice search more suitable for me (Chinese and english words recognizing better).
Yesterday i bring the mobile to LG repair store, they just update my fireware, voice search it works at few times, then google voice search failure again .
I wonder problem caused by i linked to gmail account , and some setting wrong ?
Can i logout the gmail account from android system to try again ?
