I've had my S5 for 2 weeks now, it's my return to android after about 4 years of highly jailbroken iphones. I made the switch as soon as work decided to allow phones but no jailbroken or rooted devices. (High security)
WOW did Samsung and Google really step it up while i was gone!! I wasn't blown away with the S5 interface out of the box, and its taken some time to get it right, Nova Launcher Prime and Evolve SMS saved the day... All the options are out there to make it my own and I'm having fun finding them. I feel that Ergo and Design could use some help but its possible that its just going to take some time to adapt from the iphone.
PROS:
Battery life is better than my Iphone 5
Screen size and resolution are great
Water Resistant!!
Camera is better than my stand alone Olympus
Expandable memory and super fast clock speeds.
Play Store is intuitive and the selection is wider than Apple app store and Cydia combined.
CONS:
Charger Door is a PITA but worth the water resistance (still waiting for samsung to release the wireless charging back)
I hate the volume warning when I'm using headphones (the "smart volume" fixed onboard music, but not pandora)
Had to disable Google Search in order to access S-voice with in-line headphone button from locked phone, now I have no talk to type from the keyboard... Still looking for a fix.. Anyone?
Ergo and Design:
Worried about my camera lens becoming damaged from protruding out, can't get a case cuz I'm waiting on the charge back
Protruding camera also makes the phone unstable when I'm using it on my desk
Lock button is right across from volume button, makes it hard to hit one and not the other, should be on the top
Headphone jack really should be on the bottom, headphone wire goes under my shirt so I need the slack when using the phone, not to mention that everyone put the phone in there pocket upside down.
All in All still the best smartphone I've ever had.. and the list is long
