mycellium is indeed being talked about a lot, some maybe you can try it like blockchain or yobit. I do not use a smartphone because I focus on crypto only on the PC, because I think accessing crypto will be more convenient if on a PC.
I even heard about mycelium wallet first. Is the wallet intended for a desktop or can use a cell phone. Because right now it's a cellphone wallet, I only use trust wallet. Because according to me, turst wallet is already a recommendation for a cellphone wallet.
