aptX support in FP4?

Hi everyone.

When connected with my BT box (BT Box S2 – Pro-Ject Audio Systems) streaming only works with aptX off (see screenshot).
All other phones at home work well (Samsung and Motorola).

Does this means FP4 does not support aptX?

If true, this is a serious issue on a phone with wireless sound support only…

Hi, I’ve done some troubleshooting and can probably explain why some users are reporting the bug as fixed, while others still have issues. The FP4.SP21.B.048.20230215 update does indeed fix aptX HD.

FP4 does - but not with the Android version released so far. With LineageOS 20, which is based on Android 13, I have no problems using aptX. So hopefully with future updates this will be fixed in the regular Android version of Fairphone as well.

Just updated my FP4 5G to SP29.B.069.2023051.
BT aptX still doesn’t work
I switched it off but that bug should be fixed asap! I didn’t buy this PF and then will not be able to use expected features.

Welcome to the Fairphone community.

Please be aware, this is a user forum, so you are not addressing Fairphone employees, but users like you and me.

A fix for the Apt X bug is announced for one of the next updates. I will post a link, as soon as I found the topic.

Hello everyone, We are aware that the issues related to aptX were only partially resolved with a previous software update. I’m happy to share that our Software Team has prepared a fix for the remaining 2 variants of aptX, and that it will likely be included in the July update. I’ll let you know when the timing is more concrete.
