    The android phone is saving old service discovery data, and still thinks your device is the same as the first time it connected to it. Try to turn off the BLE on the phone, and turn on/off the phone again. If you still have the same problem, try to force a service discovery by using nRF Toolbox, choose DFU and connect. The app automatically does a service discovery when the dfu service isn't found. After this, connect with the nRF Toolbox UART.
