He visto un video en youtube
donde aseguran que instalando la app Lgcamera+ y configurando con un script, se puede sin root grabar en 4k a 60fps. Yo NO lo he probado, pero os lo dejo por si alguien se atreve.
"These are the steps i took to make my Samsung Galaxy Note 8 film 4K 60FPS
First you will have to download the LGCamera App from (rubberbigpepper)
This is the link where i got the app from:
-
https://www.apkmonk.com/app/rubberbigpepper.lgCamera
After you installed the app open it and go to settings, within the menu there is a button with a screwdriver with a wrench. Klick it and then go to Edit camera script remove everything and replace it with the text underneath
preview-size=%pref_width%x%pref_height%
video-size=%video_width%x%video_height%
camera-mode=1
cam_mode=1
cam-mode=1
video-hfr=60
preview-fps-range=60000,60000
Make sure you entered the script right
That’s it, hope you enjoy it"
