Vivo X21i is simply a variant of original Vivo X21, I consider it a variant rather than a separate product. The main feature of both phones is the bangs on the front panel. Many people say that Vivo X21i and OPPO R15 Copy the design of the iPhone X, but I do not see another way to place the front camera, speaker, and other sensors. Yes, there's bangs, and there's nothing we can do about it. I hope that soon the producers will figure out a way to get rid of it. The variation, I must say, is quite interesting. Like, everything is almost the same, only the chipset is different. There are also specific combinations of the amount of RAM with the drive. The screen is inherited without distinction-the same cut under the front camera Super AMOLED with a diagonal of 6.28 "and the resolution of 1080x2280. The slightly different dimensions-a fraction of a millimeter, but still. A drop of another battery-more, 3245 mah. The body is covered with glass from behind. The fingerprint scanner is traditional, placed on the back panel.
Vivo X21 and OPPO R15 have 6.28-inch displays, and they have almost the same size. In addition, the back panel of both smartphones is made of glass. If the front panel looks almost the same on smartphones, the rear panels have some differences. For example, Vivo X21 comes with a vertical double camera and a flash in the left corner. There is also a fingerprint scanner and a company logo in the center of the back panel. As for OPPO R15, it has a horizontal dual camera and a flash in the upper left corner, while the fingerprint scanner is also located in the center. By the way, both smartphones are equipped with ports MicroUSB, not USB Type-C. I think this is a big drawback for these devices. Luckily, they have 3.5 mm audio. Thus, Vivo X21i and OPPO R15 are really very similar to each other, and only on the double back chamber, they can be distinguished. In this category, it is impossible to choose a winner, so both smartphones get from me one point. Keep in mind that I can get wrong on information but I love to avoid mistakes.
Vivo x21i is built on the chipset Mediatek Helio P60. OPPO R15 is also equipped with a new processor MediaTek Helio P60 with a clock frequency of 1.8 GHz. It also has 6 GB of RAM and 128 GB of internal memory. The smartphone supports MicroSD memory cards with a capacity of up to 256 GB. Helio P60 is a middle-class processor. At the moment we do not know the results of benchmark tests, but I think that the smartphone will have about 100 thousand points in AnTuTu. As well as many devices Vivo model Vivo x21i has modifications with a different amount of RAM and drive. The RAM capacity can be 4 or 6 GB, the onboard flash memory can be 64 or 128 GB. But the combinations are unusual: the standard make 4 + 64 and 6 + 128, and here the version with 4 GB of speed is equipped with a storage capacity of 128 GB, and 6-gigabyte is limited to 64 GB of built-in flash memory. Weird, but the price tag is the same-2698 yuan (26300 rubles) in both cases. The ability to extend the drive is supported by a memory card up to 256 GB.
The front camera has moved from Vivo X21 without changes-24 MP, self-timer, artificial intelligence, providing smart backlight, AI-makeup, AR-emoji, ar-stickers and everything else. The main is described as 12 MP + 5 MP, as well as in the case of Vivo X21 mentioned the ability to shoot a 24-megapixel photo. The 12-megapixel module has a variable aperture from F/1.8 to F/2.4, an additional 5-megapixel-f/2.0. Auto-focus-double PDAF. Artificial intelligence is actively involved in the selection of plants and photo processing. On board is a smart assistant Jovi, who, judging by the advertising materials, "knows what you need, better than you.
As you can see, Vivo X21 and Oppo R15 are very similar. They have a similar design, bangs on the front panel and a fingerprint scanner on the back panel. However, Vivo X21 has a vertical rear camera and an OPPO R15-horizontal camera. In addition, these smartphones work on different processors, but the performance seems to be the same. I think that OPPO R15 makes better photos, but we have to wait for real examples to make a conclusion. Now begins the most saturated period in terms of presentations of smartphones. Following the OPPO R15 and R15 Dream Mirror Edition, which will have to impress all their cameras, Vivo X21 and X21i are strong competitors. Also a while ago, the company announced a model called X21 UD, which speaks for itself. Both novelties show a striking resemblance to the iPhone X and can be considered the best of its clones on Android, although not equipped with top processors.
