dji Osmo Action 4
To take advantage of the sensor size, the other two haven’t done great deal of software refinement in terms of video quality compared with GoPro 13 (I have GoPro 13 Hero, DJI OSMO Action 5 Pro and Insta360 GO 3S).
You need to go for DJI OSMO Action 5 Pro or Ace Pro 2 both seem to have bigger sensors(1.3 inches I believe) for multipurpose use and good low light performance
I just unboxed my action 4 and thought the same, phone number for app registration to activate the device, super long tos..

I’ve been using the SJCAM C400 for hiking and honestly really like how small and easy it is to carry around. The dual-camera setup is probably my favorite feature since you can switch between regular footage and POV without having to carry another camera.
u can look for sjcam c400.
If you're trying to stay on budget, don't overlook something like the SJCAM C400. I've been using one for motorcycle rides and travel, and it's been a fun little camera to bring along because it's small, easy to carry, and doesn't make me feel bad about taking it everywhere.
try sjcam c400 bro.
Go for the SJCAM C400, its a better budget camera than the C300 with its high resolution and decent stabilization. Its compact, lightweight, and complete with accessories out of the box
