I recently acquired a Samsung A21S phone (about 2 years old) that I was going to use permanently as the Teslogic display. It doesn't have a SIM card and I removed pretty much all the other apps and connections on it. It was working OK but recently it started having a problem where it says "Transmitter not found Searching for device" and then a second or so later it says "Transmitter found connecting" then a very brief flash of a message saying "Fetching data from device" then the Teslogic display is working ok. After about 20 seconds (the amount of time can vary) it will again disconnect. I have tried everything I can think of in various sequences like turning bluetooth off and on, clearing the bluetooth cache, restarting the phone, uninstalling the app etc etc. I removed my normal S10 phone from the car and used the Tesla keycard in case it was a conflict with the S10, but that made no difference (previously when it was working Ok I had the S10 in the car too (as it is the key for the Tesla). In desperation I did a factory reset on the phone and started again, all to no avail. It seems like if I persist for a while it will eventually connect and stay connected. My regular phone (Samsung S10 5G) works fine. So before I decide it is a problem with the A21S and junk it, do you have any suggestions for overcoming the problem. Thanks.
