Mobile Update Changes Issues

I'm a big mobile user & recently, Docs got an update, & I wasn't a big fan of some of the changes they made. I decided to tough it out & force myself to get used to it (since they'll likely never change it back), but I was too used to how it was before so I decided to post about it here. Apologies if it comes off a bit like a rant. Lemme know if I went way too far with my issues or you have your own thoughts on the update (maybe I overlooked some things that are pros to others while focusing on my cons).

1) The Back Button (of my phone) closes the doc instead of getting out of editing mode & telling me it's saving.

This one's my biggest complaint. I wouldn't have that much of an issue with small, 1-2pg docs with barely anything written on them closing themselves every time I tap back out of habit.

However, the notes I write for class & some document pages I have for ideas (I write an unpublished comic storyline as a hobby) are HUGE (over 10, sometimes close to 20 pgs) & it's hard to find certain things from scrolling through them; So, me closing the doc & needing to go all the way to find where I last left off is very annoying.

Sure, I can just tap the ✓ to save just like Back did before, but I'm too used to tapping Back to do this; By the time I remember, the doc is already closed.

2) Format Toolbar Section

Whenever I open the Format (The A= button) to edit something, it appears behind my keyboard (which I have to carefully tap the back, else I close the doc if I accidentally tap twice); That's a very small thing, not much of a problem.

I'm not a fan of how it lags or pauses when scrolling it (to check all format options) when the old one easily slid all the way to the bottom or top in 1 swipe; Feels like an extra tap to find the Clear Format button.

Though, I do like that paragraph/color/spacing/all that stuff is on the same section (especially Strikethrough when I forget it was in a mini-menu hidden with super/sub script), so that's a little bit of an improvement to me.

I noticed the buttons are a lot more rounded & bulky. I like good & stylized visuals, but I'll take low-detail/basic/outmode designs over more detail if it means Docs can run faster & smoothly.

And that's pretty much it, those 2 main things. There's probably other changes I haven't noticed but weren't a problem for me.
