Hi,
Recently I purchased the RC2 to fly my Air 3 and noticed that it is noticeably much laggier than the DJI Fly on my Pixel 6 phone.
The most annoying part is when switching between cameras and video/photo modes.

Please, optimize the controller software or the DJI Fly app to run smoothly on your hardware, this is crucial to flight safety and user experience. It is unacceptable for the real-time picture to freeze when switching between the cameras.

Thank you for your attention! Hope to see this solved in a future update.

I don't think it is unacceptable for the image to be upset when switching modes. When changing camera, the entire video processing chain has to be re-programmed with different values, very difficult to avoid the effect on the image during that process.

Most phones can be recording with the wide angle sensor and swap to the tele sensor in the same clip without missing a frame. The M3T can split-screen the wide camera with the thermal camera to see them both at the same time. The Zenmuse L2 can steam the M350's FPV cam, L2's RGB camera while viewing the live colorized point cloud being produced. This is all done on an older version of Ocusync too.

Could it be you have an SD card in the controller?  I found a slow SD card installed in the controller will make it respond very laggy,  easily tested by removing the SD card with it off.

I do not have an SD card in my controller.

Well, it looks like beside the two new antenna, not much has changed from the old RC then... Does the RC2 still freeze when you take several 48mp shot in a short time? Does it still lag when you touch the screen to perform the action requested? Does it still use standard pots instead of Hall sensors for the sticks?

I don't have any experience with the RC 2 but the one weekend I used the original RC was pretty terrible. Maybe I'm just too used to the RC Pro. Between long boot up times, laggy response time to user inputs, cheap flimsy feel to it, dim screen in sunlight etc. It would be much better and also cheaper to get the kit with an RC-N1/N2 and get a $100 dedicated Android phone to keep in it. Faster, brighter, bigger, SDK support, ability to add a sim for mobile data etc. This would be a much better way to fly imo.

Hi, Yaros. We appreciate your feedback. I will forward this to the related team to check. Will it be fine if you post footage showing the issue with the RC 2? We appreciate your patience.

ts really odd what a mix bag of reviews these RC/RC2 controllers are getting,    Ive flown my a lot this year,  approx 30 million feet and dont have any of these issue with it,  ontop of that getting an android phone for SDK support is pointless as none of the consumer drones going forward are getting SDK support.

Part of me still holds out hope that DJI will release a Mini 4 SDK and possibly one for the Air 3. The second is less likely. Who wouldn't prefer a bigger, brighter screen? Or one that can be turned on and paired with DJI Fly opened in 10-15 seconds? The RC took me well over a minute to be ready to fly. There's several other advantages that the RC-N1/N2 has that I didn't even mention. One is battery life. With the screen having it's own battery you'll be able to fly hours longer with the phone method. You can also have the screen positioned better if you use a mount adapter. Install 3rd party apps like Air Control, UAV Forecast or FlightRadar24. You can have an HDMI out or just cast your screen very easily. Tons of more storage is also in the phone for offline maps, downloaded media etc. You can also use Quick Transfer with a phone, not with the RC's. The phone is also immune to the ever increasing update cycle that DJI uses to force us to update hardware when we don't need to. Ocusync 2? Ocusync 3? Ocusync 3+? Ocusync 4? Phone doesn't care and will work with them all.

30 million feet... Sound like a huge number and then once converted it comes down to 9000km....

It is not the distance that you fly, but more what you do with the drone...

I haven't used the RC since I was given the RC Pro for the same reasons mentioned by John..

I presumed that with the RC2 DJI would have fixed all the issues of the old RC, but if it still lags behind between inputs and the sticks still feel the same as the old RC then it makes you wonder what did actually change to make it an RC2...

When I first got it, I was trying to take a few 48mp picture within a minute with the RC and the remote screen just kept freezing on me. Then I read on this forum that I was not alone with this issue...

Since then, I no longer use the 48mp option...

All of these remotes being mentioned ( and really every DJI product we deal with ) are bulletproof. If you have a problem with your controller and you are sure the firmware is updated, well then you have a hardware problem. Just send it back to DJI and get it replaced. It's not that complicated, they stand by their warranty and will swap it out with another if the hardware is to blame.

And yes it is perfectly acceptable for the DJ RC to lag a bit between switching camera modes between photo / video. This may not happen on the better RC pro or RC plus , well duh it's a way better controller with more tech on board to handle all of that data being transmitted.  Your Pixel 6 also probably has more powerful processors that the budget controller you purchased for your drone.

I would say 75% of our tech support calls are firmware or user error related. The other 25% are hardware problems and DJI takes care of them quickly via the online repair request.

They already stated on the SDK git hub that they have no plans for the majority of the consumer drones to get the SDK,   but Ive also seen some one else state middle of 2024,  so they cant even get their own ducks own a row on that one.

Never had the issue with the 48mp images,   but I did find slow SD cards in the controller gave me assorts of issues,  then I swapped to a faster card and never had any more issues.
