Infocus CS1 A83 (C2107) Android Tablet Review

I’ve already shown some pictures, listed specs and reported Antutu benchmark results for Infocus CS1 A83 Android tablet powered by Allwinner A83T octa core processor. I’ve been using this tablet as my main mobile device for about a week, and for about 3 to 5 hours a day, and I’m now ready to write a full review reporting my experience with this Full HD tablet. General Impressions I mainly use a tablet to browse the web, check emails, play some casual games like Candy Crush Saga, watch some YouTube videos, and Skype calls, and I could not really fault the tablet for any of these applications. Having said that, my reference device is only ThL W200 smartphone powered by Mediatek MT6589T processor with a 5″ display @ 1280×720, and for all the tasks listed Infocus tablet is much better because it’s more responsive, the 1920×1200 is crisp, and the cameras […]

U-Boot and Linux Source Code for ODROID-C1 Board Has Been Released

Hardkernel ODROID-C1 board, a more powerful $35 alternative to the Raspberry Pi, garnered a lot of attention when it was announced last week. At the time source code was not available, but as scheduled, U-boot and Linux source code is now available, and the full Android SDL should be released on February 2015. Instructions to get the code, and build both Linux and U-boot are available on ODROID-C1 Wiki, and I’ve just given a try to Linux instructions myself to see if I would encounter any issues in Ubuntu 14.04. Download Linaro GCC 4.7 toolchain from Linaro or Odroid website. Install the toolchain. They install it on /opt/toolchain, but instead I’ve installed in ~/opt/toochain, so I don’t need superuser permissions: mkdir -p ~/opt/toolchains tar xvf gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux.tar.bz2 -C ~/opt/toolchains/ Add the following lines to ~/.bashrc export ARCH=arm export CROSS_COMPILE=arm-linux-gnueabihf- export PATH=~/opt/toolchains/gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux/bin:$PATH To apply change, log out and log in, or run: […]

Sony Xperia Z4 Tablet Ultra Could Feature a 12.9″ Display, a 64-Bit ARM Processor, 6 GB RAM, and More

That’s only a leak, but if true, the upcoming Sony Xperia Tablet Ultra would be a real beast with a 12.9″ IPS TRILIMINOS touchscreen display with 3840 x 2400 resolution, a Qualcomm Snapdragon 810 64-bit Octa core processor @ 2.86 GHz coupled with 6GB LPDDR4 RAM, and 64GB internal storage. Sony’s tablet ould also come with an HDMI 1.4 input port allowing 4K recording up to 30 fps, which looks like an odd feature for a tablet. The battery capacity would be rather large as well as 12,100 mAh, yet thickness only 8.6 mm, which might be possible due to the massive screen. It would most probably run Android 5.0 Lollipop.

ODROID-XU3 Lite Board Ubuntu Review – Setup, Usability, and Performance

After testing ODROID-XU3 Lite with Android 4.4, and finding a workaround to some HDMI issues, I could finally try out Ubuntu, or rather Lubuntu with LXDE instead of Unity, in Hardkernel low cost octa-core development board. I’ll start this review by explaining how to install and setup Lubuntu on the board, followed by running various program to test the system usability as a desktop computer with LibreOffice, Chromium, XBMC, and 3D graphics, and finally run some performance tests with Phoronix Test Suit, build the Linux kernel natively, and transcode a video with avconf. Setting Up Ubuntu on ODROID-XU3 Lite All firmware images for ODROID development boards, can be found on odroid.in website, and if you want Ubuntu 14.04 image, go to ubuntu_14.04lts folder, to select the latest firmware file for your board. The latest image for ODROID-XU3 (Lite) is currently ubuntu-14.04.1lts-lubuntu-odroid-xu3-20141105.img.xz, it’s the same for micro SD card or eMMC […]

How to Modify HDMI Output Parameters in Linux for ODROID-XU3 (Lite) Development Board

Good news, I’ve finally managed to make HDMI output in my ODROID-XU3 Lite development board work with the Ubuntu image after some more tweaking. So ODROID XU3 Lite Ubuntu review is coming in the next few days. But first, I’ll explain the few steps I went through, in case others experience a similar issue. I downloaded, extracted, and flashed the latest Ubuntu image to a micro SD card with dd to give another try at running Ubuntu on my board, but no luck, I still got that black screen, albeit the system boots properly, as I got the command line using the serial console. During my Android review of ODROID-XU3 Lite, I noticed the system would always revert back to 720p60 video output, and HDMI output settings can be selected in /media/boot/boot.ini with the following content:

WeTek Play Android & Linux DVB-S2 / DVB-C/T/T2 Receivers are Now Available for 109 Euros

I reviewed Wetek Play Android media player with a DVB-S2 tuner this summer, and although I found it pretty good for a dual core media player, and liked its PVR functions, more work was needed to fix several bugs, and improve “WeTek Theater Live TV” app. Several months later, they must consider their devices ready, as they’ve now launched their online store selling the DVB-S2 and DVB-C/T/T2 versions for 109 Euros, and a version without DVB tuner for 99 Euros, all including free shipping worldwide. Let’s remind us of the specifications: SoC – Amlogic AML8726-MX dual core Cortex A9 @ 1.5GHz with a dual core Mali-400MP GPU System Memory – 1GB DDR3 Storage – 4 GB NAND flash + 1x micro SD slot Video Output – HDMI, AV (CVBS + R/L audio) Audio Output – HDMI, AV, and optical S/PDIF Tuners – DVB-S2, or DVB-C/DVB-T/DVB-T2 depending on model with two […]
