July 27th, 2016 1 comment

Jiayu S3 and S3 Plus are your typical Android smartphones powered by Mediatek MT6752/MT6753 octa core Cortex A53 processor with 3GB RAM, 16GB flash, and a 5.5″ touch screen display. The news here is that Jiayu Germany (a reseller, not the manufacturer), and Team M.A.D (Mediatek Android Developers) comprised of XDA members, have releasing three custom ROMs based on Android 6.0.1 for the smartphone: Cyanogenmod13, Paranoid Android (AOSPA) and AICP (Android Ice Cold Project), which contrast with my Iocean MT6752 smartphone still stuck on Android 4.4.4.

Jiayu_S3I’ll reproduce the technical specifications of Jiayu S3+ phone for reference:

  • SoC- Mediatek MT6753 Octa-core 64-bit ARM Cortex A53 processor @ 1.3 GHz, with ARM Mali-T720 GPU
  • System Memory – 3GB RAM
  • Storage – 16 GB eMMC + micro SD slot up to 64GB
  • Display – 5.5” IPS capacitive touchscreen display; 1920×1080 resolution
  • Connectivity – 802.11 b/g/n/ac Wi-Fi , Bluetooth 4.0, GPS / A-GPS, FM Radio
  • Cellular Network
    • 2G – 850/900/1800/1900MHz
    • 3G – UMTS/WCDMA 900/1900/2100 MHz; TD-SCDMA 1900/2000 MHz
    • 4G – FDD LTE B3/B7/B20;  TDD LTE B39/B40/B41
    • Dual micro SIM cards
  • Audio – Speaker and microphone, 3.5 mm audio jack for headphones
  • USB – 1x micro USB OTG port

The phone normally runs Android 5.1, and ships with the battery, a USB cable, a charger, and a user’s manual.

Beside the firmware release, you’ll also find the source code for Linux 3.10.65 and “Device” source tree for both phones, as well as proprietary vendor files on MediatekAndroidDeveloper’s Github account. Sadly there’s no Wiki or documentation at all, but it should be possible to build it from source if you are familiar with CyanogenMod.

Jiayu S3 does not appear to be for sale anymore, but Jiayu S3+ is still sold for $155.99 on Banggood, and Aliexpress.

Superbook turns your Android smartphone in to a laptop for $99 (Crowdfunding)

July 22nd, 2016 16 comments

Using a laptop shell with a smartphone is not a new concept, but products like Motorola Lapdock were eventually phased out. But some people think there’s a market here, that Lapdock may just have been ahead of it time, and with smartphone faster than ever, it now makes more sense to use them as laptop too. That’s probably why the Superbook, allowing you to connect your smartphone to a larger screen and keyboard via a USB OTG cable, has just launched on Kickstarter.

SuperbookSuperbook specifications:

  • Display – 11.6″ LCD display; 1366×768 resolution
  • Keyboard – QWERTY keyboard with multi-touch trackpad
  • USB – USB type-C port (smartphone with micro B USB  are also supported via an adapter)
  • Misc – Android-specific navigation keys (Home, Back, Menu, Recent)
  • Custom Charging Port w/ Standard US charger
  • Battery – Good for 8 hours or more
  • Dimensions – 19.3 x 28.7 x 1.8cm

Superbook also charges your smartphone. You’ll need a phone with Android 5.0 or greater, a dual core processor, at least 1.5GB RAM, a type-C or micro B connector, and 25MB free storage (100MB recommended). Why does it have minimum requirements? Because you’ll need to install Andromium OS app which provides a desktop-like interface to Android when connected to Superbook.

If you are an Android app developer, Andromium will also release an SDK to optimize your app for the platform.

The project has already raised closed to $300,000 after about half-day since the launch. You can pledge $99 to get the Superbook with a custom USB OTG cable, and a charging adapter. Shipping is not included though, and add $20 to the US, $40 to the rest of the world. Delivery is scheduled for February 2017.

$16 Bluetooth 4.0 LE Bracelet Monitors Babies’ Temperature

July 18th, 2016 1 comment

With electronics getting cheaper and smaller everyday, I’m expecting medical diagnostic / monitoring tools with become more convenient and affordable,  and products from the more advanced Scanadu, to much simpler Bluetooth blood pressure monitors will help people better monitor their health themselves. I’ll also getting frequent request about the availability of soon-to-be FDA approved Omron Project Zero blood pressure smartwatch. Today I’ve come across a simple $16.51 Bluetooth Smart bracelet that could be useful to monitor the temperature of sick babies or very young children.

Bluetooth_Temperature_BraceletTechnical specifications:

  • Connectivity – Bluetooth 4.0 LE with up 18 meters range
  • Sensor – Temperature between 32 and 43 degree Celsius with -/+ 0.1 deg. accuracy
  • Smartphone compatibility – Android 4.3+ or IOS 7.0+
  • Functions – Thermometer; Temperature Alarm; Medical Records; Health Management, Cloud Backup.
  • Power Supply – CR2032 battery
  • Wristband Length – 14~19cm
  • Weight – 19 g


The band must be worn in such as way that the temperature probe is placed under the armpit. I could not find links to the app yet. That type of product is actually pretty common, and some – such as Vipose i-Fever – also include an LCD display.

Qualcomm Introduces Snapdragon 821 SoC with 2.4 GHz CPU Cores

July 11th, 2016 1 comment

Qualcomm has just introduced an upgrade to its Snapdragon 820 processor, with Snapdragon 821 (MSM8996 Pro) with basically the same features, but the CPU frequency boosted from 2.2 GHz to 2.4 GHz for the performance cores, and from 1.6 to around 2.0 GHz for the low power cores, as well as a likely boost to the GPU clock, resulting to about 10% improvement in performance.


The new SoC with feature the same Snapdragon X12 LTE modem delivering up to 600 Mbps. It’s unclear at this point which smartphone models will feature Snapdragon 821 processor.

VLC for Android 2.0 Released with Network Shares, Multi-windows, Better Codec Support, and More

June 22nd, 2016 No comments

VLC / VideoLAN is a popular desktop video player for Linux and Windows, and it’s the program I go to when I want to watch a local video on my computer. VLC also has an Android version, but last time I checked VLC in an Android TV box, I was disappointed due to the lack of SAMBA support, and video decoding support was pretty poor on Rockchip RK3368 processor at the time.

VLC_Android_SAMBA_SupportThe good news is that the developers have now released VLC for Android 2.0, which brings several improvements including:

  • Support for network browsing including DLNA/UPnP, Windows Shares (SAMBA), FTP(S), SFTP, and NFS
  • Multi-windows/pop-up video with support for Samsung MultiWindow and LG Dual Window extensions
  • New asynchronous hardware decoder, and codecs and formats support updates.
  • Subtitle downloads via OpenSubtitles from VLC interface without having to go to the website inside a web browser
  • Right-To-Left and Complex Text Layout subtitles
  • Video playlists support
  • History has been added back (but can be disabled)
  • Less permissions required, and support for Android N

VLC_Android_Multi-windowAlthough it’s likely to work better in Android smartphone and tablets with Samsung, Qualcomm or Mediatek processors, it might be worth giving it a try in Android TV boxes too. You can do so by installing VLC for Android from Google Play.

This brings me to the software release. I understand that while OxygenOS itself is not open source, you can still retrieve the open source part and some extra binaries from the phone to build and possibly modify the image yourself, as explained on OnePlusOSS github repo:

  1. Retrieve the open source code:
  2. Retrieve some close source libraries from the phone after rooting it:

    This will create a “vendor” directory that you need to copy to the build directory
  3. You can then build the firmware:
  4. and flash it with fastboot:

OnePlus 3 sells for 399 Euros. More details can be found on the product page, and if you are interested in hacking the device (rooting won’t void the warranty btw), you may want to check the dedicated forum on XDA developer.
