Faulty headphone jack?
Phone stuck on headphones or headphone symbol on phone won't go away?
No sound on speaker?
Cleaning dirt on headphone jack has not solved the issue?
Earphone always plugged on even without connected?

Above are the issues that occur mostly on MI (& other smartphones). Now solve those issue just by installing this app and tapping a button on app :)

This app will set speaker as primary output even when headphone is connected. You can easily revert to default output with single button.
