I have an '07 RX 350 & just got the new Samsung S21. The phone refuses to find the car & the car isn't finding the phone. Help!

My previous Samsung phones paired with no problems. 

I forgot to mention that it will also blow hot air if you switch from Auto air to one of the manual air modes. It won't blow hot immediately, but you you pretty much have to stay on Auto to keep it cool.

My '07 RX350 is having some AC problems. I had the compressor changed about 2 years ago &  the evaporator coil changed about a year ago. It started out that I had a small, short whine noise when it got really hot outside, like 97*, & the AC would quit blowing cold. If you turned the AC off, waited a minute or so, and turned it back on, it would work fine. My mechanic couldn't find anything wrong. Now it has progressed to no whine noise, but if I run a bunch of errands, it will not blow cold when I restart the car-again, if I turn it off, wait, & turn it back on, it works fine. And now it will randomly blow warm air in the middle of me riding around-same deal-turn off, wait, turn on & it's fine again. Anyone have this problem? Any ideas what this could be?

I am so nervous to mess with the evaporator coil again as that mechanic cracked the dash all up! So hoping it is not that!
