nexus 7 2013 vs nexus 7 2012 aa 12

When it rains, it pours, and such is the collection of confectionery confetti that is flowing down from the Mountain View candy land. Released in October, Android 5.0 landed with the Nexus 9, yet just a few weeks later 5.0.1 was already on its way, a small update to address bugs, but which also included fast and slow-motion video recording.

LRX22G has just been released by Google, which brings the hard candy’s teeth-talking tally to 5.0.2. The update is currently only available for the Nexus 7 (2012) Wi-Fi version. Google has since pulled the device’s 5.0.1 patch.

According to XDA Developers, the 5.0.2 update addresses “issues with MountService which should now start before performBootDexOpt [and] changes related to NAND have also been pushed. Fstrim, introduced in Android 4.3, caused some serious issues on Lollipop… devices with slow NAND should now have a noticeable performance boost.”

Lollipop is definitely shaping up to be the most unusual of all Android releases so far. Google released an unprecedented Developer Preview (Android L) earlier this year, and has now pushed out two patches within a very short span of time. Additionally many users have reported major problems with their older hardware upon updating, especially when it comes to poor power management.

The existence of yet another update will also mean that OEMs desperately scrambling to get their Lollipop builds in order have yet another new version to test when conceivably the original 5.0 still hasn’t been given the green light to push OTA.

If any of our readers feel compelled to manually update, please feel free to share your comments below and let us know if there is any noticeable improvement in the software experience.

The factory image can be found here, and is officially signed by Google. Please note that the Android SDK is required to install it, as is a more advanced understanding of sideloading.

    Well, let’s hope that this means I’ll have a little lesser than the already significantly less lag thanks to 5.0 on my N7 2012

    • Marty

      In my experience, devices that use CPUs other than Qualcomm have been laggy and poorly performing. And my experience with the Tegra 3 SoC is no exception.

      • Guest

        In my experience, Nexus 9 with Tegra K1 runs smoothly with zero lag.

        • Marty

          What’s that have to do with Tegra 3? I have a Shield Tablet with the K1 SoC and it also runs smooth. It isn’t as smooth as a Qualcomm-equipped device, but it’s smoother than any past Tegra or Samsung-made CPU.

      • Calvin Wankhede

        Now that can be very relative, especially when you use the word “devices”. Becomes quite an unforgivable and refutable generalisation :P

        Kidding(/Trolling) aside, I highly doubt that the processor is at fault here. The performance loss is said to be caused by a bad I/O driver. But since nothing has been officially confirmed, we have to just rely on Google to fix what they can…

        • Marty

          As far as devices go, I currently have 10 devices that use a Qualcomm SoC. 2 devices that use an NVIDIA SoC and 2 devices that use a Samsung SoC.

          The Samsungs are: Google Nexus S and Galaxy Note Pro 12.2. Both Samsungs exhibit severe lag and stuttering. They both use a Samsung-made SoC.

          The NVIDIAs are: Asus TF300T Transformer tablet and Shield Tablet. The Asus uses a Tegra 3 and the Shield uses the Tegra K1. Both devices exhibit lag and stuttering, but the Shield Tablet exhibits these issues very minimally and perfectly acceptably. And with Android L update, even that amount of lag and stuttering is almost gone. The Asus is so severe that it’s unusable.

          The Qualcomm devices are: HTC Inspire 4G (DesireHD), HTC Sensation XL, Samsung Galaxy S3 (AT&T version), Samsung Ativ S, Nokia Lumia 1530 (AT&T version), Google Nexus 7 (2013), Sony Xperia Z Ultra, Sony Z Ultra (GPe), HTC One (M7), HTC One (M8).

          All of these Qualcomm devices – even the oldest ones – do not exhibit any lag bad enough to cause any annoyance. If they do lag, it doesn’t interfere with their operation. None of them stutter in the slightest. They all run smoothly and perform well…especially the HTC Ones. The GS3, Sensation XL both have custom ROMs (Android L on the GS3 and KK on the Sensation). With these custom ROMs the Sensation is showing troubles keeping up and smooth. The GS3 has slowed down very slightly under Android L slightly. But most certainly nothing that hampers pleasant use. The GS3 continues to amaze me how well it performs for a humble 2-core Snapdragon S4-equipped device.

      Yeah, I’m still on 4.4.2(rooted, I’m too lazy to update to 4.4.4 and re-root) and I think I’m going to go ahead and take the plunge into 5.0.2, which hopefully helps performance.

      • Calvin Wankhede

        Just dump the factory image onto your tablet already. Its worth it, even if you hate the visuals. I assure you :)

  • Dimitris Psyrras

    What about the 3g model? Is this release compatible?

    • Dan McSweeney

      No, don’t even think about trying it!
      Even though they are closely related, flashing the rom for the wifi only model could brick your 3g model.

    • Calvin Wankhede

      You need the same recovery as Grouper (the WiFi version), and after that you’re good to go. You’ll lose all 3G capabilities by flashing that recovery though, not to mention the data wipe by flashing the factory image. But if you can’t stand the fact that you don’t receive updates as fast, convert.

  • Prox

    I installed this on my nexus 7 tablet and it’s actually usable again.

    • Simon

      Hi Prox, I’ve never done an Android manual update, I am however an IT Professional with a good understanding, can you point me in the right direction for doing this? Thanks

      • Prox

        You need to unlock your tablet with adb.

        Download image above and extract, Android SDK and Java JDK.

        Install platform tools from the SDK along with the Google USB drivers in the SDK.

        Make sure Windows fully recognizes the device in the device a manager.

        Follow these steps. Change files name. Upload bootloader first followed by the zip file

        Tablet must be unlocked bootloader.

        • Simon

          Cool, thanks, on it now :)

        • Simon

          Was struggling with the ‘device not found’ error but with a bit of digging have got it loading, many thanks.

          • Prox

            You just need to point Windows to the USB driver from the SDK

      • Prox

        USB debugging must be on and I had to set the storage mode to camera PTP instead of file. There is a 5 minute video on YouTube that shows the key commands on the nexus 7. I do not follow all his commands like fully wiping first. I just unlock the bootloader and upload the new Image.

      • You can find very good instructions on the official site from Google with the images on it. Should be really easy for an IT professional. Link:

  • ArTeePee

    Much improved so far! Lag reduced a hundred fold!

  • Michael Samsara

    Might be a good idea to mention that installing the factory image this way will wipe your tablet clean.

    • Gui

      And that’s the reason I can’t be arsed with it. Downloading all my comixology and google play music files again, ugh…

  • Brian Walker

    I installed this last night, but haven’t really run it through it’s paces yet. With my N6 sitting right next to it, grabbing the 7 feels like infidelity.

  • John Sullivan

    This works far and away better than 5.0. Huge performance improvement. If you tried 5.0 and rolled back to something else in frustration (as I did), this update is worth a try.

  • billy

    has anyone received the OTA for 5.0.2 on the N7 (2012)?

    • Liam M

      Nope nothing yet in the uk.

    • districtjack

      Yes. Just received it now

    • Justin

      Still haven’t seen an OTA update notification for 5.0, 5.0.1 or 5.0.2. My Nexus 7 2012 Wi-Fi tablet is still stuck on KitKat 4.4.4, even checking daily, still nothing. Seems my VERIZON Samsung Galaxy Note 3 might get lollipop before my Nexus. Go NEXUS!!! Get those updates!

      • alfredo

        I finally got it today.

        • Rohan Agarwal

          i did too. Is it any better after the update? Should i keep it on kitkat or upgrade it to L..??

        • Justin

          Yea, I finally got it OTA from 4.4.4 to 5.0.2 on Wednesday. Things have been pretty smooth. There have been some hiccups, but nothing major.

  • Eddie

    Nexus 6 is now available at a discounted price only at (Nexus Phone Deals,com)

  • boringfrog

    I used the “nexus root toolkit” to flash the factory image, a bit easier than using SDK.

  • kishore

    i have nexus 7 2012 edition but i dont know how to update to lollipop i hope android authority make in detail video to help people like me to install 5.0.2 version on the device.

  • erkr

    Slowmotion video with 5.0.1????

  • down/under/out

    I’m reading lots of 5.0 updates for everyone that has G, both gens. What about Moto X (1st gen) …..USA/AT&T ????

  • crutchcorn

    “What the F***” I said, seeing the title.
    These updates are far too quick…

  • Just_Saying

    I tried 5.0 and did not like it at all. I then tried 5.0.2 and still didn’t like it. Rooted 4.4.4 is doing just fine and not a smidgeon of lag. Franco Kernel does wonders, too bad it is not compatible with 5.0.2. I still like the Nexus 7 as it is the ideal size to use while laying in bed. All I can say is “THANK YOU WUGFRESH!”

  • Owen Lednor

    The OTA file for this update has been found by XDA user lynchie14 and is already on a thread full of every OTA update available (Thanks to RusherDude, great thread). Currently untested by me, but I doubt it will be a problematic update. Link for file download is Here and the link for all of the OTA updates for Nexus 7 2012 is Here Just remember that you must be on the most recent android 5.0 update and follow an online guide (I believe android authority has created one for OTA update sideloading) to apply this without having to wipe your entire system or wait :D anyway hope this helps and is noticed and lots of thanks to XDA memebers lynchie14 and RusherDude.

  • districtjack

    Just received the update OTA on my 2012 nexus 7. ANDROID 5.0.2 LRX22G

  • Paul K

    There is huge improvement in terms of convinience although many sites mentioned this is as a minor update. My Nexus 7 2012 no longer experience noticable lag, browsing is smooth even with max allowed tabs reached, Youtube plays fine, Facebook starts faster than ever, Flash integrates just fine with my browser, video playback works just great and no longer random reboots. In addition, my device became hotter running 5.0 after fifteen minutes or so, the problem I am no longer facing on 5.0.2. I can’t confirm if it might possibly elevate your gaming experience due to the fact that I don’t play games. It should be safe to upgrade and what Google did to make Lollipop updates available to our old device was truly unexpected and appreciated.

  • RoTheChamp

    I have not even gotten the OTA update yet

  • Joel Phua

    I’ve flashed it on mine and it is wonderfully faster!!! It works just as quickly as my Moto G (with just a bit of occasional lag).

  • Ronald Espiritu

    just got OTA for my Nexus 7 2012. Finally…….I was hesitant so I backed up my stuff and let it run. No problems during install. took about 20? minutes. Seems to be working smoother…no it IS smoother.. No app problems and battery life is still great. Only thing I noticed is screen auto-rotate seems to hang sometimes. Maybe CPU is just getting dated? Most likely one of my older Apps. Just not too fond of the new interface. Have it on my Nexus 5 for a few months and still not liking it much. Cant be helped i guess progress moves us forward. Anyways 5.02 seems to have given my slow Nexus 7 some new life. Much more “smooth” Much better than choppy Kit Kat. Thank you Google for updating us older Nexus 7 owners.

  • lillipop2

    This update brings only bug fixes and optimizations. For now, Android 5.0.2 is deployed on this model, it is likely that other Nexus devices will be the next to be served.

  • Gailie

    My Nexus 7 2012 received the update over the weekend 5.0.2. None of my applications will open. They all force close, including chrome. The tablet is near brick status now. It has slowed to a crawl and the touch screen response appears to have suffered the most. I am hoping for a patch. Soon.

  • joey

    Bring back kitkat for the Nexus 2013 . . . Nothing but problems with lollipop, especially with WiFi!
