Hi there, I am flying with Go4 4.1.15 and FW.07 and everything goes well. Upon the FW.09 released, I repeatedly got reminder of update when Go4 initiate and ignor it as usual. It was fine till yesterday. A station red "FW update is required" pop up in the top status bar during fligh (The area normally show the flight mode say GPS, Opti or ATTI etc). What will happen next? Ground my bird? Any one tried fly 4.1.15 with .09? Any problem? Is the OTG work in this combination (I some times use it)?
Too much question. Your advice is much appreciated.

I fly with 4.1.1.5 and .09 firmware plus OTG (on android), I do not have any problems that I did not have in the .07

It looses signal for a second every 5 flights or so, and the image transmission can get messed up for a short time now and then.

Yeah it's your drone but dji forced you what to do, you can unlock it.you have a PM

GO4 .15 works well with the latest firmware including OTG.

I am flying combo 4.1.15 and FW 0.900 as these are the latest known good builds of app and fw. So far, so good.

Edd, I would recommend you update your firmware to the latest one. If you have any problem with the new firmware, please inform us.

But not android 8, yet, right?
I have the feeling, the GO4 may not like OREO that much

Thanks all for your valuable advice. Just updated to FW.09. It pairs with Go4 .15 very well so far. Just flew 2 batteries, one with wifi and the other with OTG. No irregularity. Will try other functions soon.
