I have a Lumia 1520.3 and last week iv been to a show so i wanted to recorded my band in 4k but the video stop each 20min with a message like "you have reach the maximum length for this recording" then i need to start it again and again each 20min, btw i have a 64gigs of memory stick and it was only at the half at the end of the show, so i presume the problem is not the space !! WTF ??

There's a 4Gb file limit for recording files it should automatically continue and do a sequential rename. it's around 352MB per minute for 4K video so in theory you should be able to record 180mins but if there is any access to the card which is long enough to interrupt it will cause the recording to stop. As you fill up SD cards they can slow down dramatically especially if the card is well used

What did you mean by "if there is any access to the card which is long enough to interrupt it" ?? I don't have any apps in my SD card, only pictures and music !!
