This is the second samsung mobile device I have ever bought. First samsung I had was the original Galaxy tab 10.1, not good at all, laggy, crashed a lot, etc.. I was disappointed. Switched to iPad and never wanted to look back. For smartphone, however, I find iOS is too restrictive (no bluetooth sharing to non-iOS devices, everything has to go through iTunes, etc.. which is not a problem for me on tablet) so I stick with Android. Few reasons I bought the Galaxy S5 over the competitors for me was the S-AMOLED screen (I have always amazed by it since previous Galaxy S iterations, probably not that amazed anymore though since LCD is catching up in terms of image quality), the 16MP ISOCELL camera (I am aware megapixel is not equal to image quality, but 4MP HTC camera just doesn't do the job well if you download it to your PC or try to crop the image, you lost that much image detail). Fingerprint sensors is convenient way to unlock the phone, sometimes pattern or passcode can be guessed, but not fingerprint. I don't use the heart rate sensors or pedometer that often, so I consider that feature a gimmick.The plastic bezel looks so cheap on the S5, but then again I always use a case for my phone. I did not get to feel my HTC one M7's aluminum body that often. I went without a case for a while and then dropped the phone, luckily to carpet floor and no damage. So at the end of the day, choose cases with premium feel and the phone would feel premium also. Overall the S5 feels snappy even with much-hated touchwiz. I will use custom launcher anyway so touchwiz is not really an issue for me. This is a big step up from the last Samsung mobile device I owned, and might have just restored my faith in Samsung again.
