If you don’t want to root your phone, this is the best setup to use when using remote play with the PS4 and an android phone.
A high quaility clip to go with this high quality wire.
Below are some PS4 clips and OTG wires bundled together. The first combo looks like the best deal. I would definitely check out the other sellers for these items, because they are cheaper.
This one looks pretty good as well.
This on looks like it could be a more universal mount because it uses suction cups, but it’s price dose not include shipping.
