Does anyone have this unit and are Using AA?

When it first came out it was great.  Now through several phones the problem has only gotten worse.

If I request the unit to make a call it confirms who I want to call then it says it's calling then the radio comes back on.  After several tries it may work.

Anyone else have this problem?

I'm currently using a Samsung S10+

If yours is working what phone are you using?

Any tips???

Thanks for any advice!
