Projector screen and projector (NE Heights)

Best for someone good with tech, I've had this a while and worked great with an older Samsung phone using wifi to project what my phone played onto the screen (or wall) but never got it to work well again when we changed phones and household wifi years ago and realized it's collecting dust here. Has charger and an audio cord to plug into something like computer speakers for sound, projector has a speaker in it but not loud. Can also connect via hdmi (I don't have one). Hopefully can work for someone but no guarantees sadly. Screen is maybe 4ft x 4ft, ?metal, sturdy, folds down, has stand.
