I had a Galaxy S3 and this had now evade sometimes slow after all these years. The consideration was either a S5 or wait for the S6. Since my S5 of the Opktik and the size did not like and do not feel like waiting the S6 had, I ordered this one. The benefits are almost a Kind mass to S3, but with a larger screen and a more powerful Snapdragon 800 processor as compared to normal S4 version! One thing is clear as a Telekom branding plan, This can be removed very easily but if you want to. I removed it and then made a Antutu test. This spat me out nearly 43,000 point and thus more than the S5 which is pretty impressive! Update on Lollipop also comes yet for this device! I do not regret buying this smartphone!
