Ok, so I'm up for an upgrade in September on my phone and I want to try and get a Samsung phone. My question is, which is the best? I don't want super expensive, and I want a lot of storage space, and I was thinking of whichever one is waterproof since I work with preschoolers. But I'm trying to research before I make up my mind. Can you tell me which you think is best and why? I really appreciate it. Thank you! 😊
