[Samsung Galaxy Nexus] jonstrong:
I wonder if what you're observing is due to one or more of your apps not playing nice with 4.2? The official 4.2.1 is running beautifully on two Nexus 7's in our house (since Christmas), and is great on my unlocked/rooted Nexus 10 (stock ROM still). Also been running XenonHD on my GNex for a couple of days -- not long enough to test your statement, but so far XenonHD (based on 4.2.1) is running incredibly well on my GNex -- at least as fluid as CNA 3.8 was. The ONLY area in which I see some lag is when I go into Settings / Apps -- it seems to take a few seconds to fetch and catch the full list of Apps before I can scroll smoothly without any hesitation. Aside from that, I'm not seeing any indication that 4.2 is laggy... I'll be curious to see if that changes over the next few days.

I really don't mean to side-track a CNA thread - not my intention. CNA was clearly my favorite ROM, but my reasons for liking it are apparently a bit different than yours, and I'm also apparently not having quite the same experience with XenonHD that you write about.

I used every toro version of CNA for several months, and 3.8 stable had been on my GNex since it was released 3+ months ago. Carrying and using the phone from early morning until bedtime I'm pretty familiar with CNA, and have used it in combination with several different kernels (lean was/is my favorite at the moment) and a wide variety of tweaks applied through Trickster MOD.

I have enormous respect for the CNA dev's skills and judgment with regard to construction and the apparent testing and care he puts into his ROMs. While I do believe that some of the CNA tweaks are responsible for its great battery life, in my experience the choice of kernel and CPU settings can have an enormous impact on battery life -- perhaps more than the ROM itself. For example - with CNA, I did far better using leanKernel than I ever did with the default Faux kernel included with CNA.

If it looked like the CNA dev would have time to roll out a version based on 4.2.1, I'd be back to try it out immediately, as I suspect it would be among the best in class. I do, however, want to try out 4.2.1 on my GNex, and that's just not possible with CNA right now, and we haven't heard so much as a tweet from the developer in three months. No criticism or lack of appreciation implied -- only noting that I have little reason to believe that we'll see a new CNA version anytime soon. If it happens, great. If not, after a wait of 3 months, I'm ready to experiment a bit.

After all the comments about 4.2.x based ROMs being sluggish, I'm really very pleasantly surprised to find XenonHD to feel every bit as fluid and responsive as CNA 3.8. I've got this running, btw, with the latest stable leanKernel. I'm not seeing any errors at this point either.

Re: lock screen differences: I added clock and weather widget from HD widgets to the lockscreen -- and then removed the default clock widget. When I wake up my GNex, the HD widget is the default view. Removing the original widget (or perhaps moving it's position in the widget list?) is the key to having your chosen widget become the default view. Being able to put any widget I like (also an option) on the lock screen , along with setting wallpaper, battery pct on/off, allowable lockscreen rotation, etc offers a lot of customization options.

Re: 8 lockscreen targets -- if that's a critical feature for you, then it's no contest. I've never had any desire for more than 3 or 4 lockscreen targets, so the 5 provided in XenonHD is fine for me. Having 8 would be overkill for my purposes.

Again - I don't want to stay off-topic for the thread, and apologize if I've done so - but in fact the customization options are very nice in XHD, including extensive nav bar tweaks and the ability to add widgets to the nav bar, 8 different choices for status bar battery icon style and even animation speed. Lots of status bar toggles to choose from, and Notification Toggle works just fine as well (I use both). The LED control options are actually excellent, and I can "record" any vibration pattern I want to use as well. MMS theming is built in and looks great.

Again - props to CNA, probably the best 4.1.2 ROM out there for GNex, and I hope that the dev one day has time to share further development with us as Android continues to evolve. For now, though, I'd just suggest that folks try to be open-minded, as it seems that some are offended if anyone suggests that a 4.2.x ROM might offer an experience for the GNex owner comparable (or better?) than CNA 3.8.
