Please I need a solution on my Htc one, I was on settings and I mistakenly activate a voice function, now the touchscreen is hard to swipe, I tried to shut down but what it comes up with is only restart, the function I activated now gives me a voice response on any action I input on the phone, help, I don't know how to deactivate that function back, now Its very hard for me to pick a call with the touchscreen

First of all, did you try going thru the device manual? I do know most peeps don't read manuals.

You can go back to settings and look for voice and input settings, am sure voice control can be deactivated using the options under that menu (I use a Samsung device)

Thanks, it works
