nRF toolbox/nRF Connect unable to connect to bluetooth on android dev phone but connects on others

[needhelp123]

Hi, weird issue. I am using the nRF toolbox to connect the nRF52832 (configured for HRM) for use on android. The thing is, on my personal phone ( Samsung galaxy s10+) everything is working as expected and fine. I have a dev phone (no SIM card atttached), a samsung Galaxy A10, that i try to run the same thing on, no changes. It cannot find the Ble device. I used nRF connect to try and find it but no luck, it can see a lot of other devices though. The A10 dev phone has been completely updated to most recent software, and is connected to wifi. It can even grab a gps location, I have tested it. What should I do?

Just so the cart is behind the horse so to speak.

Does the app have BT access authorization?
And have you disconnected the other phone from the nrf device?

Yes. I went into settings and gave the app full permissions manually. I'm pretty sure You don't need to request permission to access Bluetooth as it is a normal permission. Nonetheless, I have accepted any request given on said device. And yes i have disconnected the other phone from the nrf device.
