Video playback

I’ve just started using the mini 5pro dronebut found a problem with video playback.ive recorded a short video from the drone camera I sent this to my phone dji fly app but saved to my phone sd card standard 64g mini sd.i find the video but when try to open it the video just buffers for an age and doesn’t load.both my drone and controller have u3 v30 mini sd card but the sd card in my phone is just normal 64g mini sd

What happens when you copy the video to a computer and attempt to play it there in VLC?

I’m not sure how to do that I think the problem is my phone not being able to handle the framerate I did Google my phone and says it can playback drone footage but the phone is limited.its a samsung ao4s so an entry level phone.it was recomended to use a faster sd memory card.i only have a standard 64g micro sd.i will try a u3 v30 card and see if that help.ill update on that in near future. This is my 1st drone so new to this.but ordered sd reader from dji so I can put videos on laptop.hopefully a better sd card in phone will work.so at this point I don’t think this is a dji issue more on my side.cheap phone standard sd card rather than u3 v30.but thank you for your help ilk update ASAP when I’ve tried new sd card
