I would advise you to look up One Plus Note 9 and 10 Pro. considering Kana's actual height, those two would fit the size of whatever she's holding. they're bigger than a TV remote and can act as one if you have a smart TV (via bluetooth). it's why my TV remote is gathering dust somewhere. and this is without taking into account folding phones (2 or 3 folds). not sure when you last bought a smart-phone but I happen to have a 5 year old one that would give most budget laptops a run for their money (both processing power and battery life), hence the increased size, and it's cheaper too. smart-phones stopped being just phones close to a decade ago and are more of a portable computer and a multi-tool...
