I have had several posts on here as of late about my issues with my drone after a FW update. loss of range, video transmission weak signals. I tried FW downgrades/upgrades, I almost sold the thing.
plug your phone into your computer and check how much storage you have left! My Samsung S7 was almost maxed out. 1 gig left. Computers start to act poorly when they are almost out of memory resources, phones now are basically computers. I switched my phone to an iphone 7+ and re-calibrated everything, and it all came back! after doing a factory reset on the Samsung S7 and giving it to my wife, the drone now works with it as well.
Happy flying
