Hello guys ! I have problem with my Phantom 4 remote controller! I bought controller second hand and it was working perfect but yesterday when I turned on the RC amd the aircfaft and when I started the linking process controller started flashing blue as it should and when i oressed the linking button on the aircraft the controller stoped beeping and the indicator witch was blinking blue turned off at all and in the same time it disconnected the phone and all the buttons on the RC stopped to make the beep noise ! I turned the RC off and when i tried to turn it on again the indicators for the battery are there but no indicator for connection and there is no beeping sound for welcome or from any of the buttons and when i turn it off there is the sound for turning off but it is not that laud like normal and it is like bugged!If someone knows what i can do please text me!
