Hi, I'm Bhavik. Welcome to JustAnswer. I'm reviewing your question now, and will reply back ASAP.
Hold your phone in your Right hand and press the up button 4-5 times. There should be a voulume key there.
I will call you . But I won't be able to call you now. Can I call you after 3 hrs from now. ?
I can definitely. But I am currently busy with some screen sharing.
Get soundabout app on play store. Open app and turn media Audi and call setting to speaker.
