So I recently saw the OTA notification pop up on my Nexus 4, and despite intending to wait for a while I decided to go ahead with it, so I'll share my experiences so far.
I've been using it for a couple of days now so have had a while to get used to it. Overall it's quite a nice update but I do have a few gripes with it. I'll try to keep each point concise and avoid the more well-known issues to avoid a wall of text.
- First and probably most annoyingly because of frequency of use, the lock screen now takes an extra swipe. Before it was lock button, password/code/etc. Now it's lock button, swipe up, password.
- No notification ticker. And overall I'm not a huge fan of the new notification system in general, it just seems to take more steps to do the same things as before. And whereas on KitKat you would see a little notification icon in the lock screen to make you aware of a notification, now there's a full notification panel. This works fine if you set it to display message contents, but if you change privacy settings to hide 'private' details, you just get the same big notification but with 'contents hidden' repeated. What's the point? Where's the mid-ground where it e.g. displays a subject/sender but not contents?
- The app switcher seems to get infinitely long now, and people are complaining of it causing performance issues. Also it doesn't reset when you reboot the phone.
- By default, Chrome tabs are integrated with this app switcher. Now, a lot of stuff is open to opinion but sorry, this is just pants-on-head retarded. Why would anyone think it's a good thing to have to search through 5 thousand previously opened apps to find that tab you kept open a few days ago? Thankfully you can disable this from within Chrome, but for sanity's sake lets hope that option never goes away.
- The stock gallery app has vanished, and the replacement is tied in to G+ which seems weird considering Google backing off from trying to ram G+ down everyone's throat.
- By default, the keyboard has no borders between the letters. This is likely a highly subjective thing but I really don't like it. Thankfully, this is another thing you can revert by changing settings.
- The flashlight toggle in the quick settings menu keeps crashing my phone. This is widely reported but I thought Google had halted the OTA to fix things like this. Apparently not.
- The battery usage meter is a bit wonky. The percentages listed don't add up to either 100% or the total used percentage. E.g. mine now add up to 11%, but the battery is at 63%.
And now for some more minor points:
- You can no longer get to silent mode by holding the power button, in fact the whole power button menu has gone except for a single option to shut down the device. I don't see why it would hurt to just leave those options in.
- The pull-down menu just feels a bit icky. I mean it works much the same as before but manages to feel more frustrating. The first swipe down to show notifications also peeks the quick settings menu, which springs back when you let go.
- As you may know, the Gmail app has now taken over responsibility of managing all email accounts. However the legacy email app is still visible in the app drawer. Why? To pop up and tell you it no longer works, of course! Seriously, what's the point of an app whose sole purpose is to tell you to use another app?
- You can no longer (AFAICT) highlight a time on the data usage graph to see e.g. what was the biggest data consumer between two dates.
Well that's the ugly stuff out of the way. Thankfully, most of the major issues I have with 5.0 are solvable this way - e.g. if having Chrome tabs in the app switcher was forced, I'd probably be flashing back to KitKat. And I really dislike the new keyboard which is also revertible. My most major remaining gripe is the extra faffing on the unlock screen.
Now for some stuff I do like:
- The new quick settings menu is much more user-friendly IMO. The KitKat one with its setting squares always looked a bit half-full; this isn't something which ever really bothered my but the replacement looks a bit tidier.
- In addition, the quick-settings are similarly improved, and probably more obvious. In KitKat, you had to long-press settings like WiFi to toggle, which quite a few people didn't seem to know, which is quite understandable IMO. Now you tap the icon to toggle, tab below the divider for settings.
- There's now a flashlight toggle present on this menu. Although it's practically unusable now because of bugs causing crashes and locking up the camera until a reboot, this is a nice feature to see in stock Android. Once they get around to fixing it of course.
- The auto-brightness function is now adjustable. Rather than an auto toggle or full-manual brightness, you now have 'adaptive brightness', with a manual slider to further adjust it.
- Notification priority. Now you can have your phone in a sort of semi-silent mode, where only whitelisted contacts (either all contacts or only starred) will trigger notifications. Nice if you don't want to be disturbed but still want important calls to get through.
- Multiple users and guest mode. Not really a big deal for me, but I can see this being useful for people who e.g. share devices.
- Pinned apps. I've not really read in to this much, or tried it out yet, but as I understand it this allows you to hand your device to someone with an app open, but otherwise locked so they can't back out and do something else.
- It's a lot easier to get to your full contact list from the dialler.
- And probably a load of other bits and bobs besides.
