I am a big Android nerd fan, loved the GPE line, was great to have a stock Nexus style OS on a flagship phone like the HTC One M8, and had official Google OS support for it. And I also prefer unlocked phones that allow custom ROM's, etc... Or even sorta like stock Android phones like the OnePlus One, running Cyanogen. Anyways, why do Android manufacturers like Samsung, and even HTC suck at updating their phones ? My point is let's say the Samsung Galaxy S5 for instance, or even the HTC One M8. Both flagships phones from last year. Both phones have the Lollipop update being released right around now, and they change the phone a little bit, but not what you would expect from a major upgrade to 5.0.1, coming from 4.4.4 Kit Kat they were running previously. My point is, they still look OS wise almost the same as their Kit Kat versions of Touchwiz and Sense 6, with Lollipop features. But come this Spring, both manufacturers will release their brand new flagships, the S6 and M9, and those will be Lollipop based as well, but will look radically different and newer OS style wise, with a whole new Touchwiz OS and a whole new Sense 7. But why the big style difference and OS look over Lollipop on the S5 ? Why will the S5 running Lollipop look outdated compared to the S6 running Lollipop ? Why even do that ? Look at Apple with their iPhone line, or Google with the Nexus phones. When iOS 8 came out, the iPhone 6 Plus, iPhone 6, iPhone 5S, iPhone 5, all got the update, and they look the same, not a different style or look to it on the older iPhone's, it's the same across the board. Look at the Nexus line. When Android 5.0 Lollipop was released, the Nexus 6, Nexus 5, and Nexus 4 all got the update, and all three phones have the same OS, all looked the same, not different style, or look, but the same across the board. Look at past history. Why does the Galaxy Note 3 Touchwiz, look so different than the Note 4 Touchwiz, running the same 4.4 OS ? The Note 4 Touchwiz is a lot nicer and newer looking, than the Note 3 running the same Android OS. Why do they do that ? Why didn't the Note 3 get a Touchwiz update, to make it match the Note 4 Touchwiz style at some point ? They are both running 4.4 Kit Kat, but different Touchwiz versions. WTF ?
