Only downside apart from the price !, is just like with all smart phones is that it is slipy in the hand to the touch. And just like all smart phones you buy a case to protect it from damage, and in doing that you get more grip on your treasured handset.
I bought this to replace my S8 and I'm glad I did ! Love the upgrades; screen is bigger & brighter, sound is clear and in stereo, camera is better, still discovering most of the features at the moment, and the icing on the cake is the extra storage and more ram to make apps run and multitasking easier is a win win ! Great product with great design thank you Samsung.
