Is this issue only occurring after 90% charge?
Does it always have the issue after 90th percent and never has the issue under before 90th percent?
This isn’t really a hardware design flaw. It seems that BraX3 running iodeOS exhibits speaker issues, most noticable at higher volume. We’ve tested the stock OS (LunarOS) and the speaker sound is much smoother. The quality won’t beat an iPhone, but it’s really close to Pixel (I randomly tested it with a couple of musicians which mentioned they don’t notice a difference between BraX3 and Pixel 7).
I created this issue on iode’s board to track progress: Crackling speaker sound at high volume (#45) · Issues · ota / issue-tracker · GitLab
Yes, the BraX3 is compatible with Yubikey. You can check this post here: Yubikey with yubikey app works on phone
We have a lot of cool community-generated articles in this forum. I plan on putting together a single topic that links to high-value how-to/guide articles from our community members.
This is great one to start with: 0x7 Brax Guide/Hype
This is also cool if you’re switching from iPhone: Switching iPhone to BraX3 Setup Example
