I recently bought a Juning 6 inch cell phone on Amazon. The reason for this purchase was to fly my DJI drone, and I am taking a trip to S.E. Asia soon, and I wanted a phone to use while vacationing. When I first attempted to connect cell phone to the drone I received a (authentication problem message). I attemptted to connect several times, and received the same message. This morning I tried again, but this time I told my phone to forget my home network, and I tried to connect again. This time it asked me my password, and allowed me to connect to my drone. I took it out, and flew the drone, and it worked perfectly. This cell phone has a brilliant 6 inch screen, dual sim, quad core. I bought this on Amazon for $79.00, but you might be able to get the same phone for less. Juning, 6 inch, dual sim, quad ore, with Android.
