Guide to Increase In-Call Volume on OnePlus 3/3T

A simple fix to increase the in-call earpiece speaker volume on OnePlus 3 and 3T. I myself own and use a OnePlus 3 and I absolutely love it. It is also the only phone which I have continuously used for more than a year and haven’t felt the need to change/upgrade to a better phone. The OnePlus 3 and 3T simply keep getting better and better with every update! While the phone duo is absolutely awesome, I happened to come across a tricky situation where, all of a sudden, my in-call volume dropped. The voice at the other end was very feeble and it was very hard to understand. If you have come across a similar situation, here is a fix to that will increase the in-call earpiece speaker volume on your OnePlus 3/3T.

    • It is safe, indeed. I have personally used this mod myself. But you need a rooted device to apply this Mod. P.S.: The actual reason for the lower ear piece volume on OP3/T turned out to be the dust that gets collected over time. I was surprised to learn that a lot of people had this issue with OnePlus 3/3T. I would suggest you visit an authorized service center; I did. They will clean it out for you for free. Until then, you could use this as a temporary fix.

  1. THAT – IS – SO – BRILLIANT !!!

    I struggled with that for few weeks though reading several XDA and OnePlus forums and… now your solution worked!

    Question: is it only this ” set to value=”92″?

    Many thanks and greetings from GER!

    • Hey there Henning! Glad it helped you. This article was based on my own experience. I owned an OP3 a year ago.
      To answer your question, I am not 100% sure about the change in code, as it has been a long time since I used this mod. But yes, the change was one or two lines max. An easy way to find out would be to compare the original and modified file via a text editor.
