Love the GS5 responsiveness; no lag time at all, far superior to my latest motorola Maxx HD and Razr Maxx. Does everything quicker and 'the way it should work'; connecting to bluetooth, wifi, doesn't drop a call in deadzones, able to find a weak Verizon signal where motorola couldn't. Screen is amazingly clear. Camera; I don't see it as superior despite the reviews, to my Maxx HD which also had difficulty with low-light. Great daylight shots. Great two camera feature allowing for skype.
Bad; the directional guidance voice volume is much louder than music volume and doesn't have a separate control; so very annoying that guidance comes on blaringly loud during a song. Have to turn the volume of music down so much, it's not enjoyable.
Bad: haven't found a program to transfer playlists and songs from itunes to phone; so as with the motorolas, i'm stuck with google play music which is inconsistent and out of control, downloading multiple versions of songs, losing them, then downloading more versions. Don't know how many times Appetite for Destruction will have to be downloaded to the phone before it remains. Then, I have 10 copies of Appetite on the phone.
Bad; gs5 loses my ringtone sometime soon after setup. Changes from ringtone, to "call coming from John Doe"....
Bad: phone is just a bit too large for one-handed operation, cannot reach the entire keyboard. The one-hand operation is a great feature; but reverts back after display times out. Why not engineer it to stay in one-hand operation after timeout? would have been a huge advantage; now, the one hand is just too frustrating to even bother using cuz it takes several swipes to activate it. This point is such an obvious drawback that could have been corrected but it wasn't.
But overall, I'm very pleased to switch from motorola after many years, to GS5. Guess I'm a perfectionist. And what they say is correct; different phones are strong in different features, so it really depends on what's important to the user.
