Hello !
I am about to start biking to work in a very crowded city. I will need to have my phone with me, for GPS guiding. I will only use the audio, so I store it in a pocket on my bag, which is facing the road near my shoulder. To be more secure in case of an accident, I would like to record my travels. So, do you know any app that could let me do recording with the screen off, where I can change frame rate (5 fps would be enough) and quality (1080p is enough as well) so that it doesn't consume too much power ? And that can work while the TTS of the GPS guides me of course.
Thank you for your help :)
