1) I bought two units of the RS97 Plus, one of them came with 1 white pixel on the LCD screen and the other came with a small red spot on the dark screen and small white pixels on the LCD screen. Do you recommend me or not to return these items? I bought it on Aliexpress https://youtu.be/Dlz2OZWSLoohttps://techpaul.files.wordpress.com/2010/04/stuck_pixel.jpg
2) What is the best firmware for PLUS V1.3 board review?
3) In RS97 Plus is it possible to use dual system without removing the internal card?
