Error when playing a video downloaded from the Dropbox mobile app on Android

Hi Elly1331, could you clarify what you mean by exactly the same? 

Could you attach a screenshot showing what you're seeing when you download the file?

Thanks for the screenshot Elly1331 

Could you try renaming the fie and/or downloading it from another browser and let us know if this persists?

Also, what is your device's exact OS version and the version of the Dropbox mobile app?

When you cleared the app's cache, did you also sign out and back into your account on the mobile app? 

I see, thanks for the additional information there Elly1331 

Out of curiosity, have you tried another wifi network or doing this via cellular data to see if that makes any difference?

Thanks for clarifying that for us Elly1331 

Do you happen to have access to the device you originally upload the files from? If so, are you getting the same results there as well? 

In that case, would it be OK if we sent you an email to have a further look internally at this point Elly1331?

Thanks for the cooperation so far Elly1331 - you've got
