I have a Galaxy S4 4G (I9505) with a 32GB external micro-SD card formatted as exFAT. I use this to record some seminars that takes often 0.5-1.0 hour. The video seems to stop after 30-45 minutes based on the video resolution, but always when the file size reaches 4GB.
I know that ex-FAT allows more than this. My device reads it fine and everything, but the camera app still enforces the limit. I'm using the stock app, on a non-rooted Android 4.2.2 (OTA update), the Samsung version not the Play one. It's also usually not a battery problem (battery is often above %50 after recording, and sometime it's in charger from laptop or power plug).
If I understand correctly, Android API allows overriding this limit and maybe making it unlimited, but I can't find any video recording application that does have this limit disabled. Can you suggest any?
Otherwise, if there is another custom ROM or whatever that I may install to get a modified stock app without the limit, I'd take that as an option, although obviously just recommending a 3rd party video recording app that overrides the limit sounds like a much less hassle (even for someone familiar with rooting and flashing, from my old Galaxy S 1 days).
