I wouldn’t be too quick to blame BT LE Audio and Auracast for your BT connection woes. I have no idea what kind of wireless connection protocol your Samsung Galaxy Z Flip4 phone supports. Are you sure that your phone has BT LE Audio compatibility? If not, then it’s possible that the Intent is connecting to your phone via ASHA, because you didn’t mention the need to use the Oticon ConnectClip to connect between the Intent and the phone via standard (legacy) BT.
I’ve heard that Android phones with ASHA compatibility are spotty in terms of providing reliable ASHA connection with ASHA compatible hearing aids. That’s usually because the ASHA support between different phone brands and models is still flaky and inconsistent. Some ASHA Android phones work well with certain ASHA hearing aids, others not quite well, depending on the ASHA implementation on each phone, which may not be 100% in sync.
Unfortunately, ASHA was originally intended as a solution to connect between Android phones and HAs without using an intermediary streaming device like the ConnectClip. However, it seems like it is short-lived, and before it has a chance to work out all the kinks and bugs, it’s now being phased out in favor of BT LE Audio. This ironically makes it even plausible that many Android phone makers might have decided not to spend the effort no improving and stabilizing their ASHA support anymore, because they now want to focus on providing support for BT LE Audio and stabilizing it instead, since ASHA no longer has a viable long term future use anymore anyway.
If you want more reliable wireless BT connection for now, and the ASHA or even BT LE Audio is flaky between the Intent and your phone, I would recommend settling for using the ConnectClip to connect via standard (legacy) BT for now, because it’s been around for a long time and all the bugs have been worked out between them. Even the More and Real (predecessors of the Intent) have had a lot of troubles with using the ConnectClip with standard BT devices, and it took Oticon a long time to figure out and fix all the bugs. But at least for now, the latest firmware updates for the Real and the More (and hopefully also implemented on the Intent) have rendered the ConnectClip connection with standard BT devices more reliable now.
I wouldn’t discount the BT LE Audio feature that will be AuraCast ready with a new firmware update on the Intent a liability. Instead, it should be one of the key reasons that would justify an upgrade to the Intent, because the BT LE Audio enables the Intent to be future proof in terms of wireless connection. But like all brand new protocols, it takes time to flush out all the bugs before it becomes reliable. So in the mean time, to get the reliability you need for wireless connection, fall back on a proven standard for it, the standard legacy BT and use devices like the ConnectClip that support that standard.
