I sent the Mavic away for repair the Firmware was on .900 which i found stable for me and i was hesitant with all the problems in forums with latest Fwares but when i got it back they changed the Fware to 3.1000 .....WHY??   I had an issue today and yesterday after updating to latest firmware .4.0000 and latest GO4 app for android cause i wanted to use the new props and try the new features now all my maps are gone and when after taking off yesterday  all seemed fine then i noticed laginess in the controls after i flew forwards bout 80m then when i got to bout 100m i lost connection(i have mine set to RTH50m) and the Mavic started decending then regained connection but the app was realy lagy and almost unresponsive so i turned around and landed.Today i tried again also i was using my PGYTECH landing gear that never caused issues before and all seemed fine for a while but noticed forward speed was quite slower than normal in P-mode but side flight controls were normal, swiching to S-mode seemed normal i swiched back to P-mode untill i got to about 150m away and it sudenly said on the controller 'LANDING' but nothing mentioned in the app and the Mavic slowly started to decend even tho i wasnt touching the controls.So i tried to nurse the Mavic back which i could but it was still decending slowly on its own till i got a lot closer then i had full control again so i landed.What is going on?This is freaking me out.I never had this issue with .900 and Go app .14  it seems from me monitoring the forums that since the new firmware update its becoming more common issue to lose control of the Mavic from RC disconection or the Mavic behaving in abnormal ways,the app crashing or laging or becoming unresponsive ect..

Can i go back to .900 by Factory reset or any ideas?Thanks for any input

To each his own but I find not upgrading to the latest FW leads to problems. Rather have the latest FW on my MP. If the FW is uploaded correctly and all checks out there shouldn't be issues that you'd mentioned above. Just my take.

Well you can't have things both ways. You wanted to use the new props and features but you also want to go back to old firmware which means you won't be able to use the new props and features.
I think you need to check all your settings in the app as some may have changed with the firmware upgrade.
Upload your flight record to PhantomHelp so that some of the more knowledgeable fliers can have a look.

For the map issue, we have been aware of this and it is the error of Here Map Server. We will fix it soon. As for the behaviors you mentioned, please kindly sync the flight records, and export the flight logs for analysis. The export way is similar with P4, I'll attach the tutorial video for your reference.

I agreed with Jenee. Please ensure that your antenna is in the right position and the environment is free of interference.
If the problem still exist, please export your flight data and upload to dropbox. Then post the link here.

Thanks for the replies
@M.C. Pilot. I agree but its also if aint broke don't fix it everything was stable for me on .900 and GO4.1.4 as I noticed lots more posts bout issues with Mavic behaving abnormaly since the latest Fware and GO4 so I was going to hold off till it and new GO4 was more stable,i don't know why DJI repair they updated the Fware not to the latest but to 3.1000 so since it was half way there and I wanted to try the new props I updated to .4.000 and latest GO4 for Android.
@Jenee 2. I took note of all my settings before updating and re-entered and rechecked my settings in GO4.

I today took out the Mavic to test in different place to fly where I never had problems.I  find the new GO4 starts out ok when I take off but no maps(I know DJI working on the issue) then it starts to lag here and there any input I try in the app responds sometimes after 5-10 seconds and the Mavic starts to behave strangely in P-Mode like u give it full forward throttle but it moves very slowly or I give it down throttle but its laggy or it suddenly speeds up to normal again.Its like the GO4 app starts to lag which effects the communication between the phone and RC and the RC and the Mavic(I am using a good quality cable and I plug in under the controller).I switch to S-Mode and its fine for bit then when the app lags it effects the Mavic controls again and if I switch back to P-Mode  the app lags and still displays im in S-mode but the controller displays the correct P-mode today the app tottaly froze up so I landed straight away.I have uploaded flight logs to cloud...how to upload to PhantomHelp?

We need your black box data from RC. The screenshot of the image interface is needed.  Please check the video below:
