Galaxy S series phones are the best. phone. design. ever!
I had an S6 for years and loved it. In Sept, because the port was toast, I was told a repair was more expensive than a new phone, (which turned out not to be true) and I was guided to purchase an A51.
I kind of hated it! Bixby turns on nearly every time I turned on the phone...the camera switches front facing to reg if you breathe on it...all the controls are on the right side so accidental pushes are annoying...it's too tall and akward in my hand...had a crazy amount of pre-installed apps I don't need/want...
I could ramble on, but my point is that the Galaxy S series has the
Best. phone. design. ever. Volume buttons at top left so you don't accidentally hit them...Bixby is a swipe vs auto open, camera is fantastic...etc.
So...I went online and purchased an S7 and will sell my A51. A local Radio Shack/Cellcom transferred my data and Viola! I have a great phone again!
