Yes they have added some good additions like the fingerprint scanner which is awesome, but alot of the other additions wont be used on a massive scale by all users.
Hardware wise, wasnt too inpressed on these either really, would of liked to see an octa-core version, plus the battery isnt too much of an upgrade.
But Ive found a clone version which in my eyes is better, comes with octa-core, looks exactly the same
Again this is only my opinion, and of course others will feel different which is there right to do so.
I may even change my mind once ive got my hands on one and have a play, but as for right now, im quite disappointed with the S5.
And I am a Galaxy User myself currently having the Galaxy S3 and soon will have the Note 3 also.
Thanks for reading.
