Describe the issue

We are working on a health-based project that works with a smart ring using Bluetooth. The problem is app and ring are working fine on 95% of Android phones. But 5% of the phones get disconnection problems in the following scenario.

The app sends a command to the ring to fetch data from a characteristic. The ring is receiving commands properly from the app(We can see lights glowing), but after 15 seconds(which is supervisor timeout) ring disconnects from the app. On the same mobiles, the NRF Connect app also has the same problem. This problem mainly occurs on OnePlus phones.

I tried changing the connection interval, slave latency, and supervisor timeout on the ringside. But nothing worked.

Can someone suggest a fix for this whether the fix should happen on the ring side or the app side?
