So I've been using 4.2.14 for a 2 days and everything is working perfectly fine

Welldone Sir, Happy that all is fixed back to Normal for You.

Here's the link to the older version. It worked like a charm then let the developers work out the bugs:

Wow. Still having the same problem in July! You would think DJI would have put a high priority on correcting this.

Dear DJI,

I am an out-of-work computer scientist with 35 years experience in many different systems and technologies from microcontrollers that hold only 512 instructions to sql systems with thousands of tables with 3 years experience in fast food because I am an out-of-work computer scientist with 35 years experience in many different systems and technologies from microcontrollers that hold only 512 instructions to sql systems with thousands of tables. Do you need help ironing this android problem out?

Dear DJI,

The Update should have fixed the Bug.

I don't receive any more messages except a Few Exceptions.

Try the v4.1.15

4.1.15 got me in the air. The phone just auto updated to the new version again. Let's see what happens.

Cross Fingers all goes well. If you have trouble rollback to v4.1.15 and disabled AutoUpdates.

Other than the app crashed out once, it's been working well.

The problem is still in the "DJI go 4" version 4.3.20.
Probably the problem occurrs only in the combination "version > 4.2.x" and "spark produced in end 2017 or early 2018". I purchaced a spark which was a exhibition sample in the shop for probably over one year. So I tried to activate it a few days ago for the first time and I ran into the same trouble that you all had in 2018 with "cannot take off" and "aircraft is locked". Without any further output of the reason. It is an impertinence of DJI to ignore that problem for such a long time.
Will it happen again whenever someone of us resets the spark to factory settings in future?
Any comments from DJI staff about this topic?

why is this tread in the state "solved"? There is no final solution but only a workaround installing an old DJI go 4.

Please I have similar issue.
I can connect and access Go 4 app
"CAN NOT TAKEOFF" "ACTIVATE AIRCRAFT"
I have tried factory reset, then updating, uninstall program, reinstall, change phones ....
I CAN connect to app NO activate prompt, Aircraft can not takeoff please activate aircraft!!!!
