Smartphone Xiaomi Redmi 4A Review / Firmware Update / Stock Rom

Posted by Andro New Phone on Friday 20 October 2017

Appearance 

Expect the most moderate cell phone Xiaomi remarkable plan would be neglectful. It instantly demonstrates this is the offspring of this Chinese organization. In appearance, the family highlights of the most recent Redmi and Mi4i/Mi4c models are unmistakably obvious, while it doesn't resemble the Redmi 4 line. 

At the season of composing the survey, the model is accessible just in two hues - gold and pink. We have a pink form on the test. In the two cases the front board is white. In its upper part there are sensors, a talking speaker and a front camera at 5 megapixels. Beneath - the equipment touch keys and the LED of the missed occasions, under the key "Home", as in the old-great Xiaomi Mi2s. 

The back cover isn't removable. In photographs it might appear that it is metal, yet in reality it is plastic. 

Construct quality, nothing crunches and does not play. The mechanical keys are customarily situated on the correct sidewall. They have a short however exact course. On the correct side there is a joined space for introducing either two SIM-cards (nanoSIM + microSIM) or microSIM + memory cards. Above - an extra mouthpiece, infrared port and sound yield. From the base there is a microUSB port and an amplifier. 

On the rear in the upper left corner is the primary camera focal point at 13 megapixel and LED streak. Underneath, under the logo, a mixed media speaker. 

Show 

Xiaomi Redmi 4A is furnished with a 5-inch IPS screen with HD determination. There is a programmed shine control sensor, there is an oleophobic covering. The show is somewhat recessed into within the case, which ought to shield it from scratches. 

In the city, the data on the screen stays discernable, however, the hues copy out a bit. 

The shine is customizable from 6.9 to 351 compact disc/m², and the difference is 1 to 543. With standard screen settings, the shading scope is marginally more extensive than the sRGB triangle. The temperature is for all intents and purposes the entire scope of brilliance, the reference one. Tragically, I can not say in regards to the array of this. 

No place is the chance to alter the tone and difference of the screen 

On the off chance that to talk subjectively, at that point the screen is great. Such a show would look extraordinary on the ultra-spending plan cell phone, as well as on the gadget more costly. 

Equipment stage 

The audit legend is based on Qualcomm Snapdragon 425 (MSM8917). This chip is made on 28 nm process innovation and comprises of four centers ARM Cortex-A53, which work at a recurrence of up to 1.4 GHz. The video quickening agent is Adreno 308. 

The measure of RAM is 2 GB, of them with a void errand director is free 980 MB. Worked in 16 GB memory with the capacity to grow because of memory cards microSD. After power-on, 8.4 GB is left, all memory is accessible for introducing applications. 

The aftereffects of benchmarks promptly demonstrate this is a spending processor, yet in the meantime for regular utilize, arcade amusements will do. The cell phone works so easily that even a ruined client will be satisfied. 

Like past Xiaomi cell phones, Redmi 4A has bolster for CDMA systems, specifically, Intertelecom. Wi-Fi bolsters b/g/n principles. There is an infrared port. Pursuit GPS satellites even without utilizing the Internet takes a couple of moments. 

The mixed media speaker is one, it's uproarious, however it obviously needs low frequencies. Amid the utilization of dissensions about crafted by the speaker and the amplifier was most certainly not. 

In the part of the working framework is Android 6.0.1 and the shell MIUI 8.2. More about the shell can be perused in a different material. 


Lamentably, at the season of composing the survey, there was no official worldwide firmware. To us for the test, the cell phone came as of now with the opened loader, since it was anything but difficult to introduce the firmware there. For myself, I picked the week by week MIUI 8.2 6.12.8 from the group xiaomi.eu, which amid the season of utilizing the cell phone ended up being great.

Autonomy

The capacity of the built-in battery is 3120 mAh. On the one hand, this is significantly less than Redmi 3 / Redmi 4, but in practice, not everything is so bad. With active use of social networks, constantly enabled Wi-Fi, 3G and a high level of brightness, the phone was able to last 1 day and 17 hours. The active screen time was 6 hours and 14 minutes. With the same use and the same battery capacity, my previous Xiaomi Mi4c smartphone stayed a day, with an active screen display of 3-4 hours. It turns out that the Snapdragon 425 processor is significantly more energy efficient than Snapdragon 808.

In the synthetic PCMark test with a screen brightness of 200 cd / m², the device lasted 8 hours and 28 minutes, which is very good.

A full 1A charger charges the phone slowly. Interestingly, the processor supports the Quick Charging technology Qualcomm Quick Charge 2.0. Using a third-party charger with support for this technology, the phone began charging much faster - at 1% per minute.

Cameras

The main camera is a 13 megapixel OmniVision OV13850 sensor with an aperture of f 2.2. Video recording is possible in Full HD resolution. The front camera is five megapixel with OmniVision OV5675 sensor and aperture f 2.2.

The camera application is the same as that of other Xiaomi smartphones, except for the manual mode, which is slightly truncated. It remains possible to change the white balance and the ISO value.

To say that the camera is excellent, you can not, but for this money, the smartphone shoots quite well.

Subjectively, I really like the work of HDR mode on Xiaomi smartphones. Below you can evaluate the operation of the HDR mode.

The front camera is not enough from the sky of stars, it is rather typical for an inexpensive smartphone.

Shooting video is not the main device. During recording, the auto focus is slow.
