I have a new a53 and it works okay with the exception of some issues I have never had with spotify turning off and on rapidly, but my primary issue and is with my with Bluetooth connection to my 2015 camry. It is not a problem with my camry which has previously worked with a 5G android phone. My husband's phone also works in my car. My A53 connects to my car just fine and plays music and connects calls, but my own voice is garbled when I try to speak to anyone over the phone. This has to be a software issue with the a53. T mobile ordered me a new A53 because of the problem, but this is an issue yet again with my new A53. I have read reports of other people on the internet who have this exact same issue with the a53. I even spoke with an agent at T-mobile who said they had a similar issue.
