A50 bluetooth problem connecting to vehicles

[BuilderJim]

I recently bought a Samsung A50 and paired it to my car. After a call I hung up and got out of car. When I came back to the car, I noticed the radio display had come on but only displaying a clock and was very hot to touch. After a lot of trial and error I figured out that the phone was messing the radio about. I did eventually sort it but it has happened since. 

Then I connected it to my van, thinking it must just be a problem with the car, and it connected fine until I left the van. When I got back a couple of minutes later, the van radio has stopped working altogether  and is useless. I cannot get power to it. 

Has anyone else had a problem with the Bluetooth to vehicle?

Regarding the car:

Honestly, the fact that it runs hot from a bluetooth signal makes the device in the car runs hot has only one explanation: The bluetooth implementation of the car is horrible.

Bluetooth is effectively a low power communication signal which isn't extremely quick either. No way that it could fry another device unless the other device is extremely buggy or of a low quality.

My only here recommendation is to run a software update in the car. The heat isn't good, thats for sure

Regarding both:Other than that, was your phone inside the car/van when it disconnected? Bluetooth has a very short range.

Bluetooth also works with a pairing of trust, this trust can be disconnected from both sides. The only way to fix is - Is to forget the trust relationship from both sides and reconfigure it again.

Personally I would also recommend testing it with a pair of already proven headphones - Thats probably the best way to test the connectivity of your phone, also because cars have their weird software oddities and their closed operating systems and headphones are a simple sound connection

When I left the car I took phone with me but it seems the radio didnt disconnect properly and froze. When I got back in 2 hours later, the head unit just showed a clock in top right corner, which had never happened before and when I looked at dash display, it still showed a call in progress. 

Normally I would've put it down to the car radio but when I connected to my van not long after that stopped working altogether and hasn't worked since. Just seems funny it only has happened since I got the A50. All other Samsung phones have been fine.

I have been getting a problem with my A50 Bluetooth. All working well, paired with 4 devices (car, dashcam, dslr, and my diabetes glucose monitor). When I do a blood test, the meter sends it to the phone app. It started to work intermittently and I suspected the meter. Car was connected OK when I checked, but couldn't find the camera. Now lost all connection with all 4 devices. Tried to reset the pairings but the phone is not now seeing anything.

Same problem on my Elantra. Called Samsung support they said to update and hung up on me. It did not fix the problem.
