Looking for Open world, exploration focused, mobile friendly game

I know I know. Big ask. But hear me out pls. And help me pls

I want a game that I can play on my phone that let's me explore a world (preferably fantasy) as I wish. I would prefer to not have "modern" setting: as in cityscapes. Or atleast lemme see some greenery if I am to be stuck in a modern setting. Touch virtual grass and all that ;)

I don't want a "now do this and then do that" typa game wrapped as an open world. Don't really have an opinion on combat. If its there great, not there also great.

FLYING/GLIDING mechanics are the biggest want. Lemme fly through the world. Please.

Gachas are fine, paid are fine. Anything that meets above requirement is fine.

Note: I have already tried Sky children of light, didn't really like it. It didn't feel like there was a lot to explore. Felt rather restrictive

And I was a Wuthering Waves player, the game has gotten too big for my device :_)
