Xiaomi Mi A2 Review with Android 9.0 Pie

Mi A2 Review Android 9.0

I had been using Xiaomi Mi A1 Android One smartphone since the end of 2017,  and was mostly satisfied with it thanks to regular (monthly) firmware update, although I was a bit disappointed by the camera overtime. Eventually I had a serious issue with Mi A1’s eMMC flash, and stopped using it at the end of last year, or roughly after one year of service, since the phone became unusable, unbearably slow. Xiaomi Mi A2 and A2 Lite where released last summer, and having seen Mi A2 was getting an Android 9.0 firmware in Q4 2018, I asked GearBest whether they could send a sample to review the latest Xiaomi Android One phone. They accepted, and I posted the first part of the review in early December. However, at this time, I did not get the update, since it was not released in Thailand, but soon enough Xiaomi Mi A2 got upgraded to Android 9.0 Pie. I’ve now been using …

Wechip R69 Allwinner H3 TV Box goes for $19 Shipped

Wechip R69

A few years ago, it was relatively easy to purchase sub $20 TV boxes with some patience, but with the increase in RAM and flash prices, it’s been more difficult to find those ultra-cheap TV boxes. It turns out there’s such a deal now on Aliexpress where Wechip R69 TV box is sold for just $18.99 shipped. Now with an Allwinner H3 processor, 1GB RAM, and 8GB flash, I would not necessarily recommend such device for your media needs, but they can be useful for some specific use cases like a simple digital signage, or even to run Linux with some efforts. Wechip R69 also looks to be similar to Sunvell R69 TV box that is officially supported by RetroOrangePi, but with the pin-to-pin compatible Allwinner H2 processor, so it could make an inexpensive retro gaming console as well. Wechip R69 specifications: SoC – Allwinner H3 quad-core Cortex A7 processor with Mali-400MP2 GPU System Memory – 1GB DDR3 Storage – …

Adiantum Enables Faster File Encryption in Devices without AES Crypto Accelerator

Adiantum performance

File Encryption is enabled – even required – by default in most Android devices, as it protects your data would you lose your phone, or have it stolen. Encryption in Android leverages the Advanced Encryption Standard (AES), and most modern 64-bit processors – like the ones based on Armv8 – come with a crypto accelerator that boosts performance several folds compared to a software only solution. But there are also many low end devices, for example based on Arm Cortex-A7, that lack crypto extensions, and enabling AES encryption would make the devices even slower than they already are. So in order to provide file encryption on entry-level hardware without comprising too much on performance, Google has developed Adiantum encryption optimized to run on targets without crypto accelerator. As explained in a Google Security blog post, Adiantum uses the ChaCha stream cipher – as used in HTTPS – in a length-preserving mode since file systems work in 4096 bytes block. The …

Toybrick RK3399Pro Board is equipped with Rockchip RK3399Pro AI processor

We’ve seen the official Rockchip RK3399Pro EVB in action last November, but this type of board is not usually for sale to the general public. The first RK3399Pro board that you could technically spend money on was Khadas Edge-1S via a crowdfunding campaign, but it’s still unclear when it will ship. Another option that I just discover is Toybrick RK3399Pro (TB-RK3399Pro) single board computer by VAMRS. Toybrick RK3399Pro board preliminary specifications: SoC – Rochchip RK3399Pro hexa-core big.LITTLE processor with 2x Cortex A72 cores up to 1.8/2.0 GHz, 4x Cortex A53 cores @ 1.4 GHz, and an Arm Mali-T860 MP4 GPU with OpenGL ES 1.1 to 3.2, OpenVG1.1, OpenCL 1.2 and DX 11 support, and NPU delivering up to 3 TOPS System Memory – 3 or 6 GB memory Storage – micro SD card slot + 16 or …
