Tricky

Phone works with other devices, works all the time the radio except Bluetooth. Connects fine but but then drops out after 5 mins. It’s weird.

Have a m18 Milwaukee radio and I can get onto Bluetooth and plays music for about 5 minutes then stops. Then I press play again and it stops astaright away. Also the on/off/volume button stops working sometimes and doesn’t turn off or volume can’t change. This a faulty product or am I doing something wrong? Thanks in advance 👍🏼
