I was happy for a while, when I received AC with replaced shell by service until I have tried to fly.
Each time I have tried to further than 50m or higher than 30m I lost  connection totaly.
What happen?
Before I sent it to seller for shell replacement everything was okay except cracks on the shell, when it back it doesn't.

Look at the warnings
  





Any ideas ??

Try these things: Take it outside to start it up, so it can see the GPS satellites, it cannot see any indoors.
Switch off the distance limit as shown on the third page. While in range of your home WiFi, log in to DJI and do not log out.

Geebax - Thanks.
I was outside, the signal of GPS was good, A/C status indicator was green, P-GPS mode, home point recorded. After take-off when I reached 50m - A/C status indicator became red with information Signal Lost, then apears warning "your flight altitude and distance have been limited to 30m and 50m, respectivly. Please try after restarting. Do not fly beyond this range" and my aircraft starts RTH procedure. I have repeat restart few times - without result. I have notice one more thing - when I  tap on A/C status when I hover just 10m away from me, the radio chanel quality switch from good to poor, when poor apear another warning about strong interference shows too.  check link to video
For me it is very strange I have flown in this place many times. Here there is from this place from last year
I have never any interference nor problems with range - until I get back my dron from shell replacement.
I hope none of the anttenas were damaged during servis work.

DJI- any clues?

Hello and good day P3KoYoT. I am sorry for the trouble and for reaching out. May I ask if the firmware of the drone is updated and what is the firmware version please? Can you please try a different location to isolate the issue and check if the problem persists. In addition please try to remove any interference like WiFi devices or stay away from interference. I will also provide you an official DJI tutorial video on reference for proper orientation of antenna. Finally please back-up files and make sure that DJI GO app is updated. Please keep us updated on the said issue for us to help you further. Thank you.

Have you switched off the distance limit as I suggested? Also, the shot showing the poor signal quality looks like it may have been indoors. Go outside and get away from any possible WiFi interference.

I believe you will stay restricted until you go on line and re-register with your DJI account. If your app doesn't allows you to do this, might be worth deleting and reinstalling.

Hi DJI Stephen and thanks for reply.
A/C firmware ver: 01.09.0200, app ver. 3.1.52, op sys. Android 7.1.2.
Application has been deleted and reinstalled again, before I start to fly I have been logged into my DJI account. AC status indicator was green before start. I will try to test it again in other place where I visit often for traing flights. I will keep you informed.

No good news - problem still exist, even worst due to distance is not limited but randomly lost signal, once on 30,80m,200m. I have no more ideas what I can do except return it back to the seller.
Open field no any WiFi network in range, never in this place before CRACKED SHELL REPLACEMENT had problem with range of 500m

What I find interesting is its range is limited AFTER servicing.  And not at some random distance but very precise 30M/50M.  And, the AC reports the limitation - clearly indicating it is a monitored internal function.  Again, check your flight distance settings; otherwise, something was set internally by the place that did the repair.  Good luck.

Hi NM_Quad as I wrote above. It is not limitation like after update of visit in the servis. My A/C now got random range. During same flight I got 30m, 80m,240m,290m and again 180m. Strange thing is that when I fly stright and controller sticks are on same position my A/C stopping saing signal lost and then fly further.  Before I sent it for shell replacement due to crack under engine mounts I was able in the same location fly up to 500m as per spec. In my humble opinion maybe one of anttenas got problem with connection. There is no other resonable explanation. Thanks for your comment.

I stand corrected.  I was under the impression it failed at exactly 50M on all flights.  Since you are getting varied limited ranges, flight to flight, I agree with your assessment of possible antenna problem.  Opening up the RC is fairly easy for checking the internal antennas, cabling and connections for anything that doesn't look quite right.  At 2.4 and 5.8 GHz, it doesn't take much of a poor connection to loose a significant portion of the signal. Good luck.

How was the controler antenna adjused ?  If the distance short and the altitude high then set the antenna parallel to the ground and if the distance should be far then set antenna parallel to the AC´s landing legs.
Make sure that the WIFI patch antennas are not covered through any mobile device (image transmission and telemetry.

Thanks for the comment, but that is not an issue of antenna settings. I know how to operate my drone, all was good almost thru 1.5 year. After getting back from servis I could not trust to the A/C it lose range randomly. Sometimes only for a second and then fly further, but in the end I got warning SIGNAL LOST, and A/C starts RTH procedure. I'm lucky because it always back to me. So I sent it again to the servis we will see where is the problem after.... I think a month or more

If you get your phantom fixed, can you please let me know what the problem was, although i did not send mine away to be repaired, i had used it quite regular, then took it out and the range was really poor kept saying connection lost, rth and it would come back. It's really annoying. I've tried rebooting, resetting, deleting the dji go and re installing, nothing works.

I'm sorry to hear that you also got problems with DJI PH3 Standard.
Do you get also like mine random range? or it is strictly limited with particular distance ie. 50m?
