We don't like it that the 2-finger swipe-down gesture for bringing the quick controls is gone, and we miss the button for clearing all notifications. Also, we're hoping that the design of the recent apps list will be tweaked by the time L is ready for release. Some might miss the lock screen widgets, but we can live without them. One of the little things we like is the intelligent automatic brightness adjustment – even if you set a level manually, the system can still fine tune the brightness of the screen if doing so is needed. And, of course, the Material Design looks pretty sweet, although we have yet to see how the Android UI will look like when the overhaul is complete. Right now in the Android L beta, most stock apps look like they did before.
Custom ROMs based on Android L should come once the platform's final version is out, along with the code necessary to build one.
JGuinan007: IF you have a galaxy note 3 will android L work on your phone I heard it will only support 64bit chips
XaErO: Android L brings new 64bit architecture (via ART) .. How much performance boost do you anticipate with this ?? or how much performance improvements it may bring over current 32bit architecture flagship crops ??
Android L will benefit from 64-bit processors to some extent. So will the 64-bit Android apps running on 64-bit hardware. Plus, Android's 64-bit compatibility will pave the way for smartphones with 4GB of RAM to be manufactured. However, one should not be expecting a huge leap in application performance out of the move to 64-bit. As a matter of fact, ordinary folks might no see any difference at all. It is the heavy apps, the ones handling large chunks of data, that might be faster on 64-bit gear, but your Contacts list isn't going to load any faster. Note that 32-bit support won't be dropped, so existing handsets like the Galaxy Note 3 will still work with L just fine.
PowTheBowl: Hows the performance boost on ART? And do apps run on ART with little to no problems at all?
XaErO: Android L brings ART as default runtime .. would this affect the apps that are currently designed, keeping Dalvik (32bit) in mind ?? or Do the app developers have to change it and make it compatible with Android L's ART runtime ??
The Android L beta is using kernel version 3.4.0-g370231c, as indicated in our phone's "About" page. As for your other question, the developer preview is missing some of the design changes that are coming. In the Android L beta, Google's apps and services are still with their old design. And about changing the colors, we seriously doubt that would be an option.
Yes and no. There are 10 country flags that you can technically use (here's a screenshot), but for some odd reason, they aren't listed in Hangouts. Perhaps an update to the keyboard will take care of this. By the way, you can totally download Android L's keyboard from the Play Store.
We don't really know. The screenshots on Google's web sites have the old icons, and so does the L beta. But they don't fit well into the whole Material Design thing, so seeing them in a redesigned form is possible.
The Android L beta does not support lock screen widgets, and we're assuming that we may not see them in the final release either.
