Wi-Fi Performance Comparison for Android Media Players and HDMI Sticks

If you’re mainly using your Android mini PC or STB to stream videos over the web or your local network, Wi-Fi performance is actually more important than CPU performance, and I’ve recently had quite a few issues with Wi-Fi with both T428 (RK3188 / Broadcom Wi-Fi module) and CS868 (AllWinner A31 / Realtek Wi-Fi module), which were only fixed after upgrading my router firmware. So I’ve decided to re-test most of the mini PCs I own with the upgraded router firmware, and the number are highly confusing, and I found out there’s probably be no easy to way to estimate the overall Wi-Fi performance of any device, and it’s most probably highly dependent on the router used, and its firmware version. My router is TP-LINK WR940N, a 300 Mbps Wireless N router with three antennas. Since I bought it, I had never upgraded the firmware (3.9.18 Build 100104 Rel.36350n) from […]

My Attempt at Adding Multiple Users Support to Android 4.2 HDMI TV Sticks

A few day ago, I noticed MoDaCo posted instructions to enable multiple users support on Nexus 4 smartphone via Liliputing’s Lilbits. They indicate that it may also work on other Android 4.2 devices, so with more and more Android mini PCs and set-top box running the latest version of Android, but lacking. multiple user support, I decided to give it a try on Tronsmart T428. My little experiment did not end up being that successful despite the picture below. But who knows, maybe some of my clever readers will find a solution. The instructions below may “work” on any rooted Android 4.2 devices including smartphones, mini PCs, media players, etc… You’ll need to install 2 apks: Xposed Framework – Scroll down on this page, then download and install XposedInstaller_2.1.4.apk. Finally run the installer, and reboot. MoDaCo Toolkit Xposed module – A link on this page will let you download com.modaco.toolkit.apk. […]

Tronsmart T428 mini PC Review

Geekbuying was kind enough to send me another RK3188 mini PCs for review. Tronsmart T428 is very similar to MK908 I reviewed earlier, with 2GB RAM and 8GB flash, but the latest device runs Android 4.2.2, its Wi-Fi module supports both 2.4GHz and 5GHz frequencies, and T428 can also be used as a Miracast Display. Geekbuying sells for the device for $96.99 including shipping, but before to buy the device I strongly recommend you read the review. I’ll post some unboxing pictures first, then carry on with my first impressions, video playback capabilities, Wi-Fi performance and some benchmarks. Tronsmart T428 Unboxing I received the device is in the package below. T428 comes with a short HDMI cable, a 5V/2A power supply, and a USB to microUSB cable for power. A close look at this mini PC shows the casing is made of plastic and metal (on the lengths), comes with […]

List of RK3188 mini PCs / HDMI TV Dongles

The first HDMI TV stick based on Rockchip RK3188 that I noticed was CloudnetGo CR9, and since then many more similar products have hit the market. I did not write about most of them as “it’s just more of the same” most of the time, but listed some in CloudnetGo CR9 post’s comment section. Today, I’ll provide a (non-exhaustive) list of devices, in no particular order, with a summary of the hardware specifications. I won’t mention Android versions since all of them already run Jelly Bean (Android 4.1 or 4.2). Retail price information, which I got from Aliexpress, Geekbuying, W2COMP, and some other sites, is provided for reference, and includes shipping unless otherwise stated. CloudnetGo CR9 – 2GB RAM, 8/16 GB Flash, HDMI male, 1x USB, 1x microUSB – Price Unknown – See review Tronsmart T428 – 2GB RAM, 8GB Flash, HDMI male, 1x USB, 1x microUSB – $99 Rikomagic MK802 […]

Tronsmart MK908 Quad Core HDMI TV Stick Review

Yesterday, I published some pictures of MK908, and this morning I updated it to the latest firmware, so it’s time to review this mini PC powered by Rockchip RK3188 quad core Cortex A9 SoC. First Boot, Settings, and First Impressions First of all, the firmware update has not changed the Home Screen, and we still get a standard Android Home Screen with an animated wallpaper. Screenshot and volume buttons are shown in the status bar, but there’s no soft power button, and no full screen button. Hopefully the power button can be added in next firmware update, and as we’ll see later the lack of full screen button is not really an issue. As usual, I’ve gone to the settings menu to configure Wi-Fi, and I had no problem to connect. The device also supports Bluetooth (built-in), and you can setup to device with VPN, as a hotspot, and add […]

How to Flash Firmware to Rockchip RK3188 HDMI TV Sticks

Yesterday, I’ve received MK908 mini PC featuring Rockchip RK3188, and a new firmware is available, so before further testing I’ll flash the firmware to the device basically using the instructions from Geekbuying. This method use standard Rockchip tools, so it should work for any RK3188 devices. But first a little rant. Those instructions only work on Windows operating systems, so if you’re using Linux or Mac, you’re out of luck until you find a Windows PC, or launch Windows in a virtual machine. This method should just be used in case the device can’t boot, or you have serious issue with the device firmware, but it is also used for firmware upgrade for Rockchip mini PCs. This is just wrong. Typical users should not be asked to install software and drivers, press the recovery button, just to upgrade their firmware. The best very way would be OTA updates, but maybe this […]
