I found so many apps which can record screen on my android device. Some of them can record audio and video at the same time, but only when I turned on the "Record with microphone" option.
That's not realy good, becouse the game sound can be a little bit noisy that way, so I need to record the game audio without using my microphone for best quality.
I would be grateful if the solution does not require a computer for audio recording.
My device is:
Sony Xperia Z2
Android version 5.1.1
Not rooted and can't root it becouse if I do, I lose my warranty.
