asus transformer pad tf300t review

Asus has done it again. After the Transformer Pad TF300 became the first non-Nexus device to sport Android 4.1 Jelly Bean, which was rolled out to the slate last year in August, the TF300 now holds the title as the first tablet outside of the Nexus family to receive the newer Jelly Bean flavor.

The Nexus 7 maker has announced that the Transformer Pad TF300T in the U.S. will be getting Android 4.2 starting today via an OTA update, with similar software update to be pushed out to the tablet in other markets not long thereafter. While the specific build wasn’t mentioned in the press release, we’re seeing reports from users who have made the jump that it’s Android 4.2.1.

It may not be the latest JB version, but at least you don’t have to deal with the many bugs that the previous build was ridden with. Alongside new JB features like Daydream and multiple user account logins, the firmware also includes some performance and stability enhancements.

Meanwhile, those who own the Transformer Pad Infinity – as well as other newer Asus tabs — can expect to get upgraded to Android 4.2.1 in Q2 2013.

Have you gotten the JOP40D update yet on your trusty Transformer Pad TF300T?

    I updated, 4.2.1 It gave me the option to switch from 4.1 launcher to 4.2 launcher, I’m giving it a try, so far, so good. Seems stable, though boot time took a touch longer. Other then that, I’m happy with the new slick layout. Thanks Asus (& Google).

  • SmartQ released 4.2 for their tablets back in January….

    where’s the asus padfone update to JB

  • Mikesphoneandtab

    I just sold my TF300 to get my TF700. However, I am confident my Infinity will get 4.2 because Asus has one if the best update reputation out of any manufacturer I have ever used. I love Asus.

      You are horribly wrong. I bought my Asus eee pad transformer tf101 2 years ago. They updated the tablet to 4.0.3 and said that they were going to update it to 4.1.1 but they never did. I’m not buying an Asus tablet again

      • Mikesphoneandtab

        Well that is their very first Transformer. When do you expect them to stop putting out updates? I can see if they set the wrong expectations but still.

      I wouldn’t trust ASUS or any other manufacturer to update their old tablets indefinitely. They’ll have new models to sell soon enough and one way to differentiate products is to discontinue support for the old one. Anyway, I’m happy that 4.2.1 appeared for TF300 but I don’t expect support to last much longer. Fortunately at whatever point support stops, I’ll root the thing and use Cyanogenmod or similar.

  • updating right now

  • DrXym

    I’ve become increasingly annoyed with my TF300 the longer I’ve owned it. The IO performance is really slow and I can be running a game and the screen locks up because Play or gmail is doing something in the background. Apps frequently report as not responding if the lockup goes on for long enough. Not acceptable at all.

    So I have installed 4.2.1 and I am hoping this resolves or at least gives respite to these issues. It’s too early to say if they have or not, but the general impression is that the OS is more responsive. This is not surprising given 4.2 was primarily an optimisation exercise but I am hoping that ASUS took the opportunity to fix their IO bottlenecks or throw in a bigger cache at the same time.

    • From what I have read on the Internet the I/O bottlenecks are to do with slow flash memory in the device, in other words it is a hardware problem and not a software problem.

      There is some information out there about moving the root file system to the external SD card and apparently it greatly increases the performance.


      • DrXym

        Yes I’ve read that too but it may be that ASUS are in possession of technical data which can improve performance, or improved drivers from the vendor, or failing that just slap a bit of memory cache on the front to smooth the worst bumps. I haven’t used 4.2.1 enough to encounter the issues I had in the past but I know from what I’ve seen that it’s still not as smooth as my Nexus 4.

      After the instalation, do you have any problems with the microphone? mine stopped working

      • DrXym

        I don’t use the microphone so I don’t know if it works or not. The rest of the OS so far has been fine for me although it’s still slow for IO. Someone said there is a new scheduler for the kernel which can fix this but it’s not in the ASUS build

    My tf300 switches on all alone while in sleep mode since i updated android to 4.2.1…anyone of you know to fix it? Thanks
