My thoughts on Lollipop 5.0:

-Booting the phone takes about 30 seconds. I have a lot of apps on the SD card, and they take a while to become available. Perhaps 2 minutes. I had to move a lot of apps to the SD card to get room for the update, so I can't compare before and after times for finding apps on the SD.

-When the phone was updating to Lollipop it said it optimized 105 apps. It does not optimize on every boot. I'm pretty sure apps on the SD card were not optimized based on number of apps.

-Music (Pandora and Play Music) still stops playing in the background when I launch some apps. The suspected 'memory leak', memory management problem, or whatever the cause, has not been fixed. So no apparent change there.

-If I create an app folder with apps on the removable SD, those apps still do not reappear in the folders when I restart the phone. No change.

-App-specific notifications are awesome. I have 'Subway Surfers' on my phone because my kids like the game. I hate getting notifications every day for an app I don't even play. I have disabled notifications for that app. Definate positive change.

-I use an app called 'Notification Toggle' to add toggles for skipping tracks, camera, battery life with numbered %, turning on wifi and cell data, etc. The Cell Data toggle doesn't work any more, it takes me to a screen that can be used to turn on/off data roaming but not data all together. Hopefully that will be fixed. The notification screen update already gives me another option (see my next comment).

-The pull-down notification menu can be pulled down again to show some settings that partly replace the 'Notification Toggle' app I just mentioned, including turning cell data on/off. It's a nice feature. I wish it were customizable. Definate positive change; it doesn't quite replace 3rd party apps for me, but that's part of the Android customizable experience.

-It takes longer to unlock. The unlock pattern/code input has been replaced by notifications, you need to swipe up before unlocking. Minor change but definitely not an improvement for me.

-Stability and responsiveness are good. I haven't noticed any lag but I don't remember noticing lage on 4.4.

-Battery life? I'm a compulsive phone charger, so I don't know yet. I like the new battery life screen. It shows charge over time like it used to, and it also shows projected battery life. It says I have 10 hours left, after using the phone for about an hour looking at settings, locking/unlocking the phone while on WiFi streaming Pandora.

-Lockscreen notifications have the following settings:

Show all notification content

will show content in new text messages and what is playing on Pandora or Play music; in Play Music it lets me skip to the next song without unlocking; I can't change tracks in Pandora from the unlock screen. Annoying change for me.

Hide Sensitive content in Notifications

lets me know I got a text but doesn't show the message; I can see what is playing and skip tracks in Play Music but not Pandora

Show Nothing

shows... nothing.

I wish I could select which apps would show their content on the lock screen; in my mind what I am playing in Pandora is not nearly as sensitive as what texts I receive.

If I get a text and there are multiple notifications on the lock screen, or if I get more than one text,it won't show the content of the texts. No scrolling to fit more notifications (like the notifications shade). So if you have a lot going on, lock screen notifications become sort of useless, and that's when they might be the most useful.

I used to be able to press the power button and skip to the next pandora track from the unlock screen. Two actions. Now: (1) I press the power button, (2) swipe up, (3) enter the unlock pattern, (4) open Pandora, and (5) skip to the next track. Convenience has suffered.

People will have different opinions, but for me personally the whole lock screen experience is a step backwards. I think there are some simple fixes that could make it very good, and I hope this is a bad start to a good feature (i.e. waiting for 5.0.1).
