My opinion re: Lag
My Droid Incredible 2 absolutely got laggy the longer I had it. I think that had more to do with GB then anything else. Phone ran great on Froyo.
My RAZR HD was fine until \\KIT KAT\\ hit it. Battery life took a HUGE hit, WiFi signal strength was less, it would take FOREVER to switch from WiFi to 3G then 4G. Not to mention the first roll out had serious bugs Moto had to address right away. (This is why I am patient about updates). It was horrible. That's when I started Rooting and ROMing.
So IME I actually blame PART of it on YOU people.
The people that clamor incessantly because:
"I WANT THE NEW UPDATE!!!!"
Why do you want it? What feature do you want?
IT'S NEW. MINE IS OLD NOW.
Yea, but name one feature you think is must have?
DID YOU NOT HEAR ME? IT'S NEW!
There have only been 2 updates that were must have for me. I really wanted ICS on that Dinc2 because the Time Warner app had to have ICS. (HTC said it was coming, then backpedaled... and I'll admit I never went HTC again because of that).
And JB was killer for me for Google Now.
Now they are trying to sell me on Lollipop. There's not ONE killer feature there I need. I don't need L.
"Better battery life"... uh.... I have a Turbo.
"Richer notifications".... *yawn*
"Whole new look" I have no issue with the current look. And boy didn't EVERYONE just love iOS when it updated it's look, right?
I'm really dreading the phone calls I get from friends and end users "OMG, I downloaded this update and my phone looks TOTALLY different!!!!"
"Trusted devices" Yea, I already have that. Thanks Moto.
"Guest mode".... *yawn
"ART Runtime" Yea, I have no doubt that will makes things even smoother but.... I have a 2.7GHZ phone with 3GB of RAM. There is ZERO slowness on this phone. OCCASIONALLY a Widget (like Hangouts) will lag as it loads new content. Any 'techy' person knows that is because of the Widget, not the phone.
Widgets and OS updates the phone was NOT designed for cause more lag then anything else.
IMO-and-IME.
