First time user here.I recorded some video on my action 3 but cannot view file from computer or iphone.
I used direct SD card to Computer reader but it only plays the sound and shows a still pic of the reecording.
If i view it on the action 3 playback then I can see it.
But when I try to view it on the Iphone it does not work.
Please help!

What phone model?  Maybe DJI has an answer for this, a screenshot, of the issue, same for the computer.

Always problems with iphones

It's because it's designed in California... :-)

My guess is (without knowing any details) that you recorded a 4k video in HEVC, but your computer/phone is old(er) so it cannot play it back. Do a recording in 1080 and see if that works.

Good call! Although my laptop is 2022 model it’s missing the HEVC app.
Once I installed it everything works ok on the computer.
On the iPhone, it’s a software issue that conflicts with the phone’s network. DJI told me to turn off phone network before downloading and it works. DJI is working on a solution for this at the moment.

we're having  a continued issue with the playback.

we can not keep deleting the app and placing on airplane and accept that as a temporary fix.  
if you see the video I am creating demonstrating the issue at hand     will this take a day a week a month and will it be an IOS app ver update and or action3 firmware as well
