How to check Bluetooth audio codecs on Android 5.0 I have an old Note 3 phone that I use as a music player. I am trying to find out if it supports the aptX Bluetooth codec. I turned on developer mode and all the instructions I can find online say to go to “Audio codec” under the “Developer Options” menu. I go to the “Developer Options” menu but there is no entry for “Audio codec.” On Android 5.0 are the codecs listed in a different place?
If it does not have aptX is that something that can be added?
The only way to check I found so far is in the Android Developer Options.
On some devices there is an entry named &quot;Bluetooth-Audio-Codec&quot;. If this list contains an entry with &quot;aptX&quot; as shown in the following screen shot it should be sure that the device supports aptX:

The screen shot is from an Android 9 tablet. Not sure about older Android versions. It may happen that you don't have no &quot;Bluetooth-Audio-Codec&quot; entry in the Developer Options menu, in that case this method does not work for you.
