I prefer using the iPhone X (6.14 ounces/174 grams) with the OSMO Mobile because it’s noticeably less heavy than the iPhone 6s Plus (6.77 ounces/192 grams) I’ve been using. This should slightly improve OSMO battery life. The iPhone 8 Plus (7.13 ounces/202 grams) is heavier than my iPhone 6s Plus, and is actually the heaviest of all of these three phones.
So why mention the weight? If you use an lens adapter on your iPhone with the OSMO, that adds additional weight to the OSMO. For example, I frequently use and love the Moondog Anamorphic lens (48 grams). I also like to put an ND filter on the Moondog Anamorphic lens (another 46 grams). This adds a good bit of weight to the OSMO (94g total). You then have to add a counterweight to the OSMO mobile. The OSMO has some unspecified weight restriction1. If you exceed the undefined weight limit, the OSMO gimbal will fail to remain balanced, steady, and smooth.
I had a difficult time pairing my iPhone X with the OSMO Mobile, and I didn’t find the answer to my issue anywhere online. Since I figured out how to resolve the issue, I thought I would write a blog post about it for those who have posted to forums and not received a solution. Hopefully what worked for me will work for you as well.
The problem: when trying to connect the new iPhone to the OSMO Mobile, I would get this error message: “Cannot find OSMO Mobile. Ensure the OSMO Mobile is available.” The OSMO Mobile did not appear in the Bluetooth Device List in the DJI Go app, nor did it appear in the iPhone’s Settings → Bluetooth.
The first thing I needed to do was update the firmware of my OSMO Mobile. You do this by connecting your OSMO to your computer’s DJI Assistant app, logging in, selecting your device, and updating the firmware if needed. This, however, still did not fix my pairing issue.
My iPhone X would not see my OSMO mobile as a bluetooth pairing choice no matter what I did. It then dawned on me: what if the OSMO, like my old bluetooth keyboards, could only pair with one device.
So, I unpaired my old phone from the OSMO, and it automatically wanted to pair with my new phone. I would suggest that even if you just bought a new OSMO mobile, it may have been a return or a refurbish that was paired and then re-sold as new. In this scenario, or if you no longer have your old phone, I’m not sure how you would reset the bluetooth pairing. Perhaps resetting the WiFi settings (demonstrated in this video for the OSMO Pro) resets the OSMO to factory defaults and would therefore also reset the bluetooth settings. Seems logical.
Here are the steps I followed to reset my bluetooth pairing. With the OSMO turned on and connected to my old iPhone, I went to the old iPhone’s Settings → Bluetooth, found the OSMO Mobile in the list, selected it, and then selected “Forget this Device.” I then turned everything off. I attached my new iPhone X to my OSMO, and the new phone then successfully saw and automatically wanted to connect to the OSMO bluetooth. Yay!
My hunch is these steps deleted the connection from the OSMO Mobile itself and made it available to be connected to another phone. Warning: Your mileage may vary!
Several people have already blogged and vlogged about this issue, so I won’t belabor it here. The iPhone 8 Plus and the X have video stabilization on both of the back facing lens. You can’t turn it off. It competes with the OSMO stabilization and can produce a bit of jitter in the background of the image.2
If you want to know more about it, I suggest you search YouTube for iPhone X OSMO Stabilization

Once upon a time I thought the weight restriction was 300 grams. But, I’ve subsequently realized that the gimbal itself on the OSMO weighs 300 grams. That figure is not the weight restriction. ↩
This problem purportedly first appeared with the iPhone 7, which introduced the iPhone’s software-based video stabilization. ↩
