In the interest of making things easy for those who are holding off on the KitKat OTA, I thought it might be a good idea to consolidate all of our experiences into one thread. This is intended to cover mainly the changes specific to this OTA over Razr M-flavored Jellybean.

I'll start with my experience/thoughts and edit in additional findings. (Note: I'm bootloader locked, and now unrooted.)

The Good

The Neutral / Very Subjective
  • The AOSP keyboard has changed; the keys are smaller and, in landscape, very squashed. You may need to adjust to it (I'm trying, but it's a struggle) or find a replacement.
  • Battery life when the phone is actively in use has not been noticeably improved in my experience; but it hasn't been noticeably worsened, either.
  • There's now a shortcut to the camera from the lock screen, which can be used even if the phone is locked by a pattern/PIN/etc. (Great if you're a shutterbug; not so great if someone else decides to troll your Dropbox/Drive account.)
  • The Google Camera app works - but Photosphere can't be used, as the Razr M doesn't have a gyroscope.

The Bad

My opinion, overall:

It's a nice upgrade, but all of little problems I've encountered (bugs, Verizon blockades, the works) make this feel like a bit of a letdown after the 6-month wait. In the end, after just three days, I find myself wishing I could take the phone back to Jellybean.

Here's hoping for either some exploitable holes or maintenance updates.

Worse battery life - On 4.1.2 I averaged around 20% after 16 hours moderate use. With 4.4.2, I'm averaging around 5% in the same span.

Lesser LTE coverage - This may be something with my area, but I can usually get 2-3 bars of LTE in the Livingston County area on 4.1.2 (I've noticed the XT907 accel in this category). While on 4.4.2, I could not get any LTE coverage in the same area, and could only find it within more populated areas.

Slower performance - I'll always be amazed by how quick the XT907 was on 4.1.2, beating out devices with similar specs in the same price category. With 4.4.2, I've noticed frame drops, stutters, and random reboots be a common occurrence over the last few days of usage.

Overall, I'm satisfied with 4.4.2, but I still prefer the overall usability with 4.1.2.

Worth noting that I am using an unlocked bootloader, with CWM and SuperSU (only really did this to remove VZW bloat and install Xposed)

On 4.1.2 the "signal bars" were calculated by a xml in, I believe, SystemUI.apk. You could simply adjust the figures to show more or less bars, which Moto adjusted to show more. But having no LTE maybe a bad radio or a problem stemming from a bad flash. My Razr M doesn't get hot, no random reboots, and battery life seems to be the same. I haven't had any problems on KitKat.

Gonna be doing some more testing in that regard. Even my M7 with its garbage radios gets LTE just about everywhere in the Metro Detroit area.

So far my experience with 4.4.2 has been positive. I agree with OP's list and would like to add these under the issue category.


ISSUE:

Decreased WiFi effectiveness/throughput - There is a noticeable decrease in performance on apps like Youtube and Chrome web browser.
Audio Popping noises - Some experience a popping noise when the sound driver starts up while others experience it during playback.

I have had the KitKat OTA now for 2 days and haven't found anything major wrong. The changes to the keyboard bugged me but I use swiftkey so that was moot. I also have an issue I haven't seen listed yet. The new sound for screen taps....it seems to give that "popping" feedback (that ive seen listed as an issue on driver start-up) ALL the time. I maybe get 1 clear sound out of every 5-6 screen taps. That is the only real "problem" I can find as of this point though. Does anyone have any insight on that?

Also activated Dev Mode and changed to ART runtime. Might be placebo but app response seems to be noticeably better! Not groundbreaking by any means but better than 4.1.2 for sure. Overall I am happy with the upgrade. Rather, will be happy once a root exploit comes up (I miss my debloating! On that note though, disabling apps never seemed to work right with 4.1.2....after hitting disable the app would show back up in active processes after a short time. Now I've gone 24 hours and 3 phone reboots and that damn NFL app is STILL disabled and NOT running as a background process. Might just have been an issue with my phone in particular before, but its fixed now!)

I am generally happy.
It fixed all the issues I had with Dhackers KitKat.

and feels about the same once you have rid of all the Bloat.

I like and I am happy that we still surprisingly got the update unlike the Galaxy S3

Happy =)

Just wanted to comment on the heat issue mentioned above:

I have only had KitKat for 2 days but I have definitely noticed a difference in heat after extended use compared to JB. One of the things I really liked about my Razr M was lack of heat so hopefully this is a fluke and I wont notice it too much in the future.

---

With that said, no big issues.

I don't like the keyboard -seems smaller, or something, The heptic feedback seems to be different too (for the worse IMO).

The lockscreen number pad seems smaller - definitely liked the number pad from JB.

I had to change the messaging app (hated the all white/lack of contrast). Using "8sms" if anyone is curious.

I also changed launchers to use the google-now launcher so the "okay google" thing would work on the homescreen and also get the transparency notification bar. But, in doing that I did lose the circle widgets which I liked. Can't win for losing sometimes...

---

On a positive note, Chrome/google searches seem to be much faster. The UI seems about the same (no complaints with JB).

If battery life can increase then I'll be satisfied with update (so far, no difference).

Thumbs up
My experience has been very positive. My phone was bootloader locked and not rooted before (and, of course, after) the OTA. I cleared the cache partition from the recovery menu post-install but have not done a FDR. General impressions:

-- UI is overall much snappier/quicker. Extremely noticeable.
-- Love the new quick settings panel that you can get to after pulling down the notifications shade.
-- KK's changes to how the SDcard works have not been a big deal at all for me. The native "Files" app seems to have complete read/write access, as does ES File Explorer.
-- Like the new clock feature to automatically add a "home" display when traveling outside a pre-defined timezone.
-- Hate the new way you set the alarm on the clock. (Really, whoever came up with that input method should be transferred to a department where s/he can never affect design decisions again.)
-- I miss the audio silencer/mute on the lockscreen.
-- Battery life has been interesting. When I first installed the update (morning of 05/15), battery life was definitely worse, probably by about 50%. It has gradually been getting better, however, and now is probably only about 20%-25% worse than JB. Why it would change I have no idea, but it definitely is (I've been keeping notes, and am sure it is actually happening). I have noticed, using the Battery History details screen, that there are a LOT less wakelocks in KK than JB. In JB, I used to see tons of "Awake" indicators on that screen that did not pair with "Screen On" indicators. In KK, there are very few incidences of "Awake" that are not paired with "Screen On." Someone smarter than me will have to explain how that translates into worse battery life.
-- It may be my imagination, but it seems like the battery charges faster w/ KK. If it's not my imagination, I wonder if that means that the apparent decrease in battery life is really an issue of improper calibration/accuracy.

I have not experienced some of the things others have reported:

-- No random reboots.
-- No changes to WiFi or 4G signals. I don't use Bluetooth so can't comment on that.
-- No popping noise when using audio. (Note: I have seen some reports in other forums that a FDR fixes this issue for those who have it.)
