We’ve seen smartphone in the past with two displays, such has Yotaphone 2 with a color front display, coupled with an e-Paper rear display that’s always on and consumes less power. ZTE Axon M also comes with two displays, but it’s a completely different beast, as both are color displays, and foldable to create an extended display when needed, somewhat like a foldable tablet. ZTE Axon M (partial) specifications: SoC – Qualcomm Snapdragon 821 quad core processor up to 2.15 GHz with Adreno 530 GPU System Memory – 4GB RAM Storage – 64GB eMMC 5.1 flash + micro SD slot up to 256 GB Display – 2x 5.2″ @ 1920×1080 displays making a single 1920×2160 screen when opened Audio – 3.5mm audio jack, microphone, dual speaker, Dolby Atmos support, AKM 4962 HiFi chipset Camera 20MP rear camera with f/1.8 aperture, PDAF, dual-image stabilization, dual LED flash Up to 4K @ 30 fps, 720p @ 240 fps Cellular Connectivity – NanoSIM…

Google unveiled their latest Pixel 2 & Pixel 2 XL premium smartphones powered by Snapdragon 835 SoC earlier this month, and while they are expected to go on sale tomorrow, reviewers have got their hands on samples, and one of the key feature is the camera that takes really good photos and videos as reported here and there. You’d think the ISP and DSP inside Snapdragon 835 SoC would handle any sort of processing required to take photos. But apparently that was not enough, as Google decided to design their own custom co-processor – called Pixel Visual Core -, and integrated it into Pixel 2 phones. The co-processor features a Cortex A53 core, an LPDDR4 memory interface, PCIe interface and MIPI CSI interface, as well as an image processing unit (IPU) IO block with 8 IPU cores. Google explains the IPU block will allow 3rd party applications to leverage features like low latency HDR+ photography, where the camera takes photos…

Qualcomm has announced a new “Mobile Platform” with Snapdragon 636 that combines eight Kryo 260 cores, an Adreno 509 GPU, and X12 LTE modem for “high quality devices with top-level features at a low price point”, which must mean “mid range”. The new Snapdragon 636 offers an update to Snapdragon 630 / 660 solutions released last year with up to 40% performance boost, 10% faster 3D graphics, and support for ultra-wide FHD+ displays (18:9 aspect ratio). Key features for Snapdragon 636: CPU – 8x Qualcomm Kryo 260 cores clocked at up to 1.8 GHz GPU – Adreno 509 with support for OpenGL ES 3.2, OpenCL 2.0 full,Vulkan, DX12 DSP – Hexagon 680 DSP with All-Ways Aware Technology, Neural Processing Engine SDK, Caffe/Caffe2 and Tensorflow support Memory I/F –  LPDDR4/4X, dual channel up to 1333MHz, 8GB RAM Storage I/F – eMMC and UFS flash Display – Up to 2160×1080 FHD+ resolution; DisplayPort and USB type-C support for external displays Video –…

I’ve been using Vernee Apollo Lite smartphone with a Mediatek Helio X20 deca-core ARM Cortex A72/A53 processor coupled with an ARM for a little over a year. Recently, I’ve received Xiaomi Mi A1 smartphone for a Qualcomm Snapdragon 625 SoC featuring eight ARM Cortex A53 cores and an Adreno 506 GPU. In theory, the latter is a downgrade, and the Xiaomi phone is indeed quite slower in Antutu with overall score of 60,161 points against 85,840 points in the Mediatek phone. 3D graphics performance is also lower with 12,849 vs 17,828 points. Both smartphone have the same resolution (1920×1080), so it’s a little confusing to be told you’d “better to play games in low quality mode” for the Mediatek phone, and “game performance is mid-level” for the Snapdragon one. But anyway Helio 20 should work better in 3D games than Snapdragon 625 if we are to believe the numbers. Most apps run fine on Vernee Apollo Lite, but one game…

5G technology is expected to launch in 2019, and Qualcomm has recently made a step towards this goal with the company announcing their first 5G data connection with Snapdragon X50 modem on on 28GHz mmWave Spectrum. The demonstration took place in Qualcomm Technologies’ laboratories in San Diego, and achieved Gigabit download speeds using several 100 MHz 5G carriers. Snapdragon X50 5G Modem’s product page lists some of the key features of the chip: Up to 5 gigabits per second download speeds Initial support for operation in the 28 GHz millimeter wave band. It can connect using up to 800 MHz of bandwidth via 8×100 MHz carrier aggregation. Supports advanced multiple input, multiple output (MIMO) techniques such as adaptive beamforming and beam tracking Composed of the modem as well as the SDR051 mmWave transceiver The modem can be paired with a Snapdragon processor to provide multi-mode 4G/5G capability, and the company expects it to be found in fixed wireless applications, with…

Karl here. Today we are going to look at the ACEPC AK1 mini PC. Here are some of the specs pulled from ACEPC’s website. The feature that is most notable to me is the included 2.5” hard drive compartment. Hardware CPU:Intel Celeron J3455 GPU:Intel HD Graphics 500 RAM:4GB DDR3L ROM:32GB eMMC WiFi:Ac3165 Dual Band，2.4G/5G LAN: Ethernet RJ45 10/100/1000M Bluetooth: BT V4.0 Interfaces USB port:2xUSB 3.0;2xUSB 2.0;1xType C;support USB disk and USB HDD Card reader: TF Card (up to 128GB) HDMI Port: HDMI 1.4 Microphone audio: 3.5mm Microphone jack x1 Unboxing & Teardown     First Boot – Storage / Task Manager Storage after first boot: Storage after update: Thermal Testing with Prime 95 Cooling seems adequate. Below is a picture of Prime 95 after 5 minutes. I am glad to see it staying at about 2 GHz considering the base frequency is 1.5 GHz. After stopping, it loses 30° Celsius immediately and after 30 seconds back to around 50° Celsius….

Xiaomi Mi A1 hardware specifications are pretty much standard for a mid-range smartphone, except possibly for its dual rear camera, and what makes it stand apart is really Android One program that promises regular firmware update, including to the latest “pure” Android version, during a 2-year period from launch. In my case, the phone is also interesting because so far I had only used smartphones with Mediatek SoCs, and Mi A1 is equipped with a Qualcomm Snapdragon 625 processor. SD625 should be slower than the Mediatek Helio X20 deca-core processor I’ve been using in Vernee Apollo Lite, but I’m curious to find out if some apps have been better optimized for Qualcomm processors. I’ll soon find out as GearBest sent me a review sample.I’ll start with an unboxing and first boot post, before writing the second part of the review in a couple of weeks once I’ve finished testing the phone. Xiaomi Mi A1 Unboxing I took a while to…
