Can someone explain why wifi has such a problem with the Spark with Android? I mean, the phone is attached to the controller. It's not like there is a great distance between them. I down graded to 4.1.15 to be able to use OTG since wifi is unusable. I used a dedicated Samsung SM-S320 Android 6.01 and G530 Android 5.01. Two different phones same useless wifi connection. What gives? Fortunately both do OTG.
