How do you use the speaker for an HTC vivid phone?

Do you have that service provided through your carrier? It may not be a feature that is supported by your carrier.

JUST UPDATE WITH LATEST FIRMWARE OR RESTORE TO FACTORY SETTINGS

try custom ROM from XDA forums. Google for it. Laos, be sure your phone is not under warranty. You cannot claim warranty for it later. This should definitely work.

remove the accu for 3 seconds and put in again :)

had the same problem with a nissan. Took the car do the dealer and they where able to connect the phone. sometimes its the car

try this

goto settings > applications > system applications > find messaging then force stop it !! ( you may not able to find that option but if you find do it )

if you just applied an update then goto htc website and tell them about your problem. that might be kernal problem. they'll help you to solve this.

replace the crystal or by a new phone

Get a flashlight and a saftey pin, pick out pocket lint from the audio jack. sadly I have had this happen to 2 phones several times.

Go to setting then go to storage then go factory data reset.... then your keyboard will come back on your htc vivid phone will come back cause i just did it
