Hello everyone,
I bought a new OM 4 a month ago. I've had experience of using it two or three times since I bought it, the first time and the last time I couldn't start the device even if it was connected to my phone, the gimbal motors do not work. The device appears to be connected to my phone in the Mimo app, but the green light continues to blink. Meanwhile, it seems that the charge of the gimbal is quite low on the mimo app. However, all of the charging status lights of the device are constantly on, so it is fully charged. In addition, the serial number of the device  appears as N / A. I have tried to restart the blueetooth settings of the device over and over again. (R + M + T). I'm really tired and regret buying it! Can anyone help with this?
Hello there serdarw. I am sorry for the trouble this has caused and thank you for reaching out. May we know what is the model of the mobile device you are using on your DJI OM4 for us to be able to isolate the said issue? In addition have you tried uninstalling and reinstalling the DJI Mimo application as well? Please keep us posted for further assistance. Thank you.
Hello, thanks for your feedback. The device that I use the application is Iphone 7+. I've tried uninstalling and reinstalling the Dji Mimo app many times but the problem persists... I have exactly the same problem, I have a Huawei P20 Pro. I did everything DJI support told me, but nothing seems to work. I'm tired too, and I don't know what else to do.
Please help us.
I’ve tried. I’ve even tried reset the phone. I've talked with DJI support about 3 times, and they do nothing. I sent them videos and nothing, they told me some DJI people from my country will contact me... Still nothing.
Awful service.
P. S. I had the problem after and before the firmware update.
Hi, I couldn't handle yet. I tried to get a help from technical support last day. Only thing they said was I need to contact with my dealer. It's like kind a joke. I couldn't have thought it, thank you(!) And so I wrote  my dealer this morning and I demanded return the product in order that get my money back. I'm waiting...
Tomorrow will do the same!!! VERY UPSET!!! Don’t even know want to buy next. Osmo 4 was fine when it was working right
Tomorrow will do the same!!! VERY UPSET!!! Don’t even know want to buy next. Osmo 4 was fine when it was working right Hello! I had the same issues described above:
- the green light continues to blink
- gimbal motors not working
- camera works in DJI Mimo app
- serial number of the device  appears as N / A
- charge of the gimbal is quite low (red in color)
I came to a conclusion, that this is a kind of a "weird" standby mode,
because green light continues to blink only in standby mode (refer to manual).
This happened to my DJI OM4 when I was comparing my iPhone with Xperia and switching between them.
So, this helped me :
1) while green light continues to blink detach the phone from the DJI OM4,
2) power OFF DJI OM4 (hold "M" button until 2 beeps)
3) power ON DJI OM4 (with the phone detached)
4) attach the phone to the DJI OM4
5) not always required step: hold "M" button until 1 beep (standby mode), repeat
P.S. Excuse me for my English, it is not my native language.
Hi everyone,
I have exactly the same problems. I bought the OM4 as Christmas present for my wife and today I tried the hole day to get it run without success. In addition to the above described problem I tried to install the latest firmware update. But it always stops at 54% with an error. Now I am really at the end with my knowledge and hope to get some help here. It's good to see that I am not the only one with these issues.
With best regards from Germany
Thomas Hi everyone,
I have exactly the same problems. I bought the OM4 as Christmas present for my wife and today I tried the hole day to get it run without success.

Now I am really at the end with my knowledge and hope to get some help here. It's good to see that I am not the only one with these issues.
I had exactly the same issue.
Connect OM4 to charger and  wait for a few minutes and then try to install firmware.
This helped me, latest firmware was successfully installed in a minute. Hello again
I had the same issue with blinking green light and above mentioned steps did not helped.
After a few hours (!!! this sucks, yes !!!) I came to another solution:
1) turn OFF DJI OM4
2) make sure bluetooth is ON in the phone settings
3) open DJI Mimo application and mount the phone
4) turn ON DJI OM4
5) wait for it to detect phone and  "broken" camera mode is opened or open it by tapping camera.
By "broken" camera mode  I mean this one:
- serial number of the device  appears as N / A
- green light is blinking
- charge of the gimbal is quite low (red in color)
- gimbal motors not working
6) UNMOUNT the phone while being in "broken" camera mode
7) wait for the message in yellow rectangle to appear, saying "phone not mounted"
8) MOUNT the phone again
9) Hold "M" button until 1 beep - this will wake the device from standby mode
This is really a shame for DJI that users have to spend literally a few hours to connect their devices to OM4.
I have iPhone 11 Pro Max and Sony Xperia 5 II, and I observed this problem with both of them,so the problem is not OS specific.
This issue must definitely be addressed in the future updates!

I can't seem to get the "message in yellow rectangeL to appear.....
This is really insane that this gimble has so many issues... After two months, the date that I sent back the device, today its been replacemented with new one. However,I have doubt about facing the same issiue again. So I have a question to those who faced with that problem. What was the production date of your device? It is located on the box, down the serial number. Mine was 2020/07. Thank you. The green light blinks and nothing happens.
The only buttons that work are zoom and on/off.
But there is something else. When I bring the top axis to 180 degrees, it either locks or starts to vibrate.
I have tried, I think, all the tips I have found here.
It's too bad that such an expensive, for my country, stabilizer, has had so little life.
Today I will go to the service center for further diagnosis. Of course, it will be cool if the problem is solved, but such situations should be kept to a minimum.
And also, I think that DJI should give more importance to this and officially warn their users about a possible malfunction. Também tive estes problemas. Após horas tentando solucionar o problema, percebi que no app mimo, na parte superior da tela, ao ativar a câmera, aparece uma mensagem dizendo que há uma versão atualizada para instalar. ( além da atualização automática que ocorre ao instalar o app pela primeira vez). Por algum motivo a instalação não completava, parava antes dos 70%. Após tentar várias vezes, finalmente concluiu a instalação e o Osmo4 voltou a funcionar imediatamente.
