Honestly, phone VR is basically dead and it sucks. Samsung hasnt done anything meaningful here in years. Regarding what #2 said about "This one: https://www.amazon.com/Controller-Compatible-Anti-Blue-Adjustable-Universal/dp/B0DQH5ZLPY?t=t=7649-2 0" - look, those cheap shells are usually pretty terrible. The optics are bad and you will probably get a headache in ten minutes. Ngl, its a waste of cash because the S25 Ultra is too heavy for most of them anyway. If you want real value, the Meta Quest 3S 128GB is the only thing that actually makes sense right now. Its standalone, so you arent risking your expensive phone falling out of a plastic strap. If you really want to leverage the S25 Ultra hardware for media, maybe try XREAL Air 2 Pro AR Glasses. They connect directly to the USB-C port and give you a massive virtual screen. Not exactly full VR, but way better than those clunky goggles. Just dont expect a Gear VR successor anytime soon, cuz it isnt happening.
