    It's is a good phone. I liked it but it's a bit small. It's like Samsungs respond to iphone 14. The camera is good but you can't compare to s24 ultra. Nice and neat. Supports wireless charging and a good battery life.

    This phone is manageable (grip wise)... takes great pics and most importantly the is battery life is AMAZING. Seriously. The battery is small and so is the form factor but this phone goes all day easily. I've had the iPhone 14 pro, s24 ultra, OnePlus 12r and the Z flip 5 recently and this phone is the champ. If you get down with Android get the s24.
