Hi there. Unfortunately not at the moment. I'll send a request to the tech team about that.
First off, this forum designates that it is for the BV9500 PRO, yet we are constantly seeing references to the 9500. Get a forum for that phone, please. This 9500 Pro is messed up enough without adding a totally different model phone into the mix.
Now, this thread was started for the PTT button , but there is very little in this thread pertaining to it. All I'm seeing in post after post about the update that isn't even for the PRO model.
To turn off the PTT button on the BV9500 PRO,
in English step 1 go to settings , system, about phone , tap build number 5 times to enable developer options . Step 2 go back to system , select developer option , go to the bottom under Apps select backround check and un select intercom. Done
Many of us have ALREADY done this & and IT WORKS. ALL credit goes to Juan M. Romero.
