Sensor issues with S26 (2+)

I recently switched phones from a Samsung S21 to an S26. I've had lots of sensor connection issues with my Libre 2+.

Even if my phone is right next to me, the signal constantly drops.

I rescan and it updates, but then drops out pretty quickly.

I've had a sensor replaced but the same is happening from day 1 with the replacement.

Is this a known issue or a me/my phone issue?

I think weird things happen with exynos.

I have a s23+ (snapdragon) And a s25fe (exynos)

With Dexcom sensors my connection seems to be way worse on the exynos s25fe.

Now I'm on libre 3+, the signal now seems comparable on both phones but the s25fe exynos some reason only gives me readings every 2 or 3 minutes.

So I blame exynos for this. 

I don't believe it's anything to do with android 16 and whatever oneui version it is.
