Xiaomi Redmi Note 4 / 4X
Update (May 2017)
The Xiaomi Redmi Note 4 with LTE Band 20 is now available! This means that the smartphone can be used extensively in the German LTE mobile network. Attention, the “International” model does not offer LTE Band 20! Only the installed ROM has been expanded to include several languages! Enclosed you will find vouchers for the Note 4 and Note 4X International as well as the Note 4 Global with LTE Band 20.
Processor and memory
With the "X" as an addition, you could almost think that this smartphone is a significantly faster model with new hardware. In reality, the addition has no meaning whatsoever. The built-in processor is - just like in the Redmi Note 4 (International) - a Qualcomm Snapdragon 625. The memory configuration also remains unchanged at 3GB and 32GB or 4GB and 64GB. The counterpart with a MediaTek Helio X20 processor intended for the Chinese market remains available. There are just a few things to consider when it comes to the supported network frequencies. Xiaomi smartphones usually do not support all LTE frequencies common in Germany. The Redmi Note 4X also works without LTE Band 20. At the same time, a special model of the Note 4 was also announced, which also supports LTE Band 20, among other things!
Here is some more information about the processor itself. The Qualcomm Snapdragon 625 is a mid-range octa-core processor that was introduced at the beginning of 2016 and its cores clock with a maximum of 2 GHz. In combination with the Adreno 506 processor graphics, the system-on-chip provides enough power for everyday applications and small games. The internal memory can be expanded by a further 128GB with a microSD memory card.
Display and camera
The display with a diagonal of 5.5 inches has a full HD resolution (1920 x 1080) and thus achieves a point density of 403 PPI. The manufacturer specifies the luminance as 450 nit, the contrast ratio as 1000: 1 and the NTSC color space as 72%. Individual color adjustments can be made via the display settings.
The main camera of the Xiaomi Redmi Note 4X has a resolution of 13 megapixels and uses a 5-layer lens and an f / 2.0 aperture. A PDAF (autofocus) is available and a dual LED flash ensures improved night shots. The front camera has a resolution of 5 megapixels and also uses an f / 2.0 aperture.
Other features include a fingerprint scanner on the back, which makes unlocking the smartphone even faster and easier. GPS, A-GPS, GLONASS and Beidou are supported for navigation. The sensor equipment consists of an acceleration sensor, a proximity sensor, a gyroscope, a brightness sensor, a Hall sensor and an infrared sensor. Dual-band WiFi is available and Bluetooth is also supported in the current version 4.2. The integrated 4.100 mAh battery, which ensures long runtimes, is also interesting.
Price and availability
The Xiaomi Redmi Note 4X was released in February 2017 and is priced at around € 160. The smartphone is available in a total of 5 different colors (black, silver, pink, light green and champagne). The so-called Hatsune Miku Limited Edition is available in the color light green and also includes a power bank and a back case with Hatsune Miku imprint.
