My phone has my life on it, and if I can't store it in my bag, that bag is not a keeper.
Personally, my two cents... I feel like you are forcing it, and you may end up using once or twice and say it's a pain.
I love a lot of bags, but if a bag does not have all my requirements, I am not willing to sacrifice and do odd things to make it work.
For me, I would not ask hubby to hold my phone. It's just goofy because what if you get separated at an event to talk to other firends. You now want your phone to check on things. You can't keep going back to hubby to ask for it, but then if you hold your phone in your hand and not in your purse, it looks silly doing that at an event, like this lady is so desperate she can't live without her phone (which I am, I can't live without my phone, but at least I can stuff it in my purse!).

Yes, you can push to stuff it diagonal, but then it takes up the entire bag. Sure, you can put stuff in the open "corners" like lipstick and credit card. But here's the problem, once you take out the phone (which now acts as a divider), all the "stuff" in your bag now just rolls back into the center. This means when you have to put your phone back in, you now have to take out all that stuff to "rearrange," just to accomodate that phone. Plus, it really looks silly in my opinion.
The bag is going to be a functional disaster, and quite frankly, it'll look like a lady who overstuffs her tiny bag that isn't working for her. I've seen that when checking out at places like grocery stores. My eyes roll. I've seen ladies who wear these overstuffed little bags and then they have to take out items, put them on the table, then have to stuff it back in. It's not a great image I would want to portray.
I'd return it and get something tiny if tiny is what you want.
Plan B... how about the mini classic flap with handle? It's not the same, but an option. I think that bag is super cute. Not sure how big your phone is and if it will fit... I would think so though as it's a rectangle and open inside.
I'm not a tiny bag person, so I don't buy tiny bags even though it's trendy now.
For me, I can't wait for the tiny bag trend to be over with (I hope 1-2 more seasons) and big bags become the it thing!
I would die for a jumbo size Coco Handle without a divider!

Hope this helps you to decide! Good luck!
