loud speaker doesn't work

[Jessiepanda92]

yesterday i got a "hand-me-down" xperia t, and it was working just fine until i realized the loud speaker stopped working. the only way i can ear anything using the phone is using earphones. i already tried restarting the phone in safe mode and it still doesn't work. can anyone help me?

Try blow down the 3,5 mm contact to remove any kind of dirt. Connect and disconnect headset while playing music from the Walkman player. 

If the problem still persists you could try to repair the phone software using PC Companion. Otherwise you should have the pone examined by a service center. Please contact your local Xperia support team for more information:

Download "Xperia Diagnostics" from google play and test ear speaker but it wont work. Plugin earphone and remove then do the test again and repeat the same no. of times. It will start working
