Last year’s Nexus 7 may get lag fix in 4.3 OTA


Though the new Nexus 7 is out in all its 1080p glory, we still haven’t forgotten about the older Nexus 7. It’s still a very useable tablet, and we’d argue that stepping up to a new Nexus 7 would be unnecessary for some. For the most part, the Nexus 7 2012 works decently well. But what about those who want to use it to its full potential?

Our own Dustin Earley wrote an article called “One year later, the Nexus 7 has gone from the best to worst tablet I’ve ever owned.” The N7 2012 was pretty damn fast when it came out, speeding through benchmarks and handling 3D games like a champ. So what happened? Well, ASUS has been known to use very poor memory controllers in their devices, including its high-end tablets. Over time, these devices slowed down due to the bottleneck affect caused by the shoddy memory, bogging down the device and not allowing the other hardware to work to its full potential.

A lot of these issues stemmed from the Android 4.2 update, which significantly slowed down most Nexus 7 tablets. However, we may be getting a fix in the Android 4.3 OTA! According to Anandtech, Android 4.3 includes support for fstrim, which will help keep the device working fast. Once the device is idle, has its screen off and its battery at around 70%, it meets the requirements to start using fstrim.

The support for TRIM was available in Android 4.2, but it was not enabled. Android 4.3 comes with it enabled, so this could be a huge help to the original Nexus 7 once it gets the OTA. Have you gotten the 4.3 OTA on your original Nexus 7? Has it made a difference? Leave a comment!

    If this is true, I’ll be reverting to stock from CM10.1 to get this lag sorted out! 4.2 is a mess :(

      Henry! Good to see you here man.

  • CPG716

    Curious as to why this article acts like the 4.3 update hasn’t been pushed to the OG Nexus 7, cause most people have it now. So it either does, or does not improve lag at this point. For me it seems it is running faster.

    • Cris Core

      I don’t have the update yet, on my N7 or my Galaxy Nexus.

      • BDG

        Nor I.

      As far as I know, it’s a staged rollout. Not everyone has the update, and enough time hasn’t gone by to accurately judge. Only time will tell! Also, don’t forget that many people who actually care would be running custom ROMs, like me. Still on 4.2.2 CM10.1

      • Kelson

        Does anyone have any idea how long a period they’re staging across? I’m still waiting for the update on mine, and I’m wondering whether it’s a matter of days or weeks, and how long I should wait before concluding the device has somehow slipped through the cracks and needs to be updated manually.

        • xPurplexAnarchyx

          I would give it a maximum of two weeks, but if you can’t wait. (Like I couldn’t, you can use ADB and sideload it to your device. http://goo.gl/ZmeGrk provided by Droid-Life.
          *note* if you do decide to update it yourself via ADB sideload I recommend you start off with the trick in step nineteen and then start. *end note*

    I flashed the 4.3 factory image on my 32GB N7 (2012) and it feels really snappy imo compared to 4.2.2.

  • sandwich

    Highly interested to hear how this affects people’s tablets in the real-world…. please make sure Dustin Earley reports on his end of things once he gets the OTA update. :)

  • Co1e

    If only I had won that contest!! Good to hear though.

  • renyo

    I’m surprised trim was implemented so late in Android considering the fact that all phones use solid state memory…

  • garpunkal

    Before reading this article I felt like my n7 speed had improved.

    :-) 4.3 user and I’m happy about it

  • redraider133

    Good to see google working to fix what they screwed up with 4.2.2 and not leaving older hardware in the dust. I loved my nexus 7, up until 4.2.2.

  • jamal adam

    Glad Google is addressing the problem. I’ll stick to my current ROM for now and will wait patiently for the 4.3 release of PA. Excited to see my beloved Nexus comeback to action as it’s been benched for a couple of weeks now.

  • Eric Rossman

    No lag here. When I reboot, it takes 20+ seconds for the widgets or app tray to start. Long load initially upon restart is the only symptom I get, afterwards everything returns to “buttery smooth” and apps load almost instantly again. I have been running my 2012 N7 unaltered ( like a normal customer) since July 2012, and the experience has been great. I now want the nexus experience on all my devices, and I can proudly suggest the N7 to non-techie friends and family. Earlier this year there was mention of N7 lag from people who had filled up their storage space, the solution was to leave at least 1GB of storage free and the lag goes away. The trim function should fix that for good though when 4.3 rolls out.

    I still have not gotten the update pushed out to my original Nexus 7 32 GB. I regularly experience the lags, so I am looking forward to the update. I did get my pre-ordered new Nexus 7, and the performance has been great on it.

  • 1966CAH

    I do not have the update yet, however I have been using lagfix (root required). This allows you to manually run the fstrim command. This helps a little, but not enough. Getting the new Nexus 7 tonight and handing last year’s down to the wife:)

    • griffithal287

      Sounds like the perfect solution lol. My wife heard me discussing the new N7 and she told me that I need to get it so that she can have mine. Definitely considering.

  • da9el

    i received the 4.3 update a few days ago. i think it works much smoother now. well, i haven’t had any lags before…

    • www.phonewbie.com

      I do get lag from time to time. Just finished downloading and installing 4.3. I’ll see if there are any improvements.

  • slimx30

    yes, asus is known for using flash memory that is pure junk. The transformer prime and the tf700 both suffered from this junk. I sold my prime because it ran like crap. I don’t know what kind of memory they used in the new nexus 7 but it makes me kind of hesitant to buy it now due to the fact that I worry how it will run in a few month or after an update. I may wait it out for a while and see how it goes

  • donger

    Trim support enabled.

  • mvp77

    My 2012 nexus 7 was a laggy mess. Seeder and fstrim helped but it was still bad. The 4.3 has eliminated most of the lag. I still use seeder to speed it up.

  • jimdriver2

    I got the 4.3 OTA on my 8GB Nexus 7 yesterday. I bought the N7 on release so I’ve definitely seen the lag, it’s been horrible at times but because it slowly appeared I was beginning to wonder if I’d imagined it. Work then got me a new 16GB N7 recently and it was night and day compared to mine.

    So far the 4.3 update seems to have helped. I’ll wait and see what it’s like over the long term though.

  • griffithal287

    I received the 4.3 update on my N7 yesterday and it made my tablet run a lot slower, even after the apps updated with optimization for 4.3. I restarted, thinking it was just a memory clog, but it still runs slow, especially transitioning between apps. I guess I’ll try a hard reset, although I dread setting up this whole tablet again (it’s never the same twice). I may as well go get a 2013 model, I think I will…
