What happens when I get a message saying "unfortunately HTC Sense Input has stopped"

Go in settings > Apps > Car. Click on "Force Stop" and "Disable" this will make the app unusable and will no longer give you an error message

I have a few questions hopefully i can help if you are still having this problem. What version of Android are you running? Are you running a task manager app if so uninstall it? Try wiping the data in HTC Sense by going ini your phones settings then go to apps then select the all tab. Go down the list until you see HTC Sense. Hit Force Stop and then clear data. Hopefully this helps. Another recommendation is an alternative launcher from the Play Store such as ADW EX or Apex Launcher. Hopefully this helps. The old HTC Sense is a resource hog and replacing the launcher will improve performance. An even bigger step would be to root the device and remove sense all together. Let me know if you need help with this.

you need to master reset your phone need help on how to do this?

you need the security code for the wireless

you can contact the service provider........

You probably gotta simply updated your phone at the htc website.

the htc sense site is having major problems,they are working on it

i followed the directions here

http://myhtcdesire.com/tutorials/fix-the-application-htc-sense-process-com-htc-launcher-has-stopped-unexpectedly

and it works fine now

its a common problem for much of the htc mobiles , even if u complain for the htc care they say they are trying to resolve it but thats not gona happen , i too had the same problem and just replaced it

All i did was take out my SD card and wait 15 seconds then put it back in the phone. I did not see the process com.htc.launcher error anymore.
