I use it in my repair shop to make sure both ear and loud speakers are working when a phone is done. Wish there was an ios version too...
This update makes the GUI unresponsive and freezes the phone after a few clicks. You have to kill the app. Very badly designed.
No it doesn't do what it says. Just tests the external speaker not the ear speaker
I use this app with a can of compressed air to clean my speakers. Works great! But be gentle with the air so you don't damage the speaker
Crashed within the first minute
Couldn't test ear speaker
