OPPO A91
Gradually, OPPO is also sending new smartphones into the race in Germany. The A-Series starts with the OPPO A91, which is already available in some markets, but is now also being sold in Germany. OPPO sales partners include Amazon, OTTO, Mobilcom-Debitel and LogiTel. The smartphone will be available there from April 18 for 299 euros.
Slim design with AMOLED display
With a thickness of 91 millimeters, the OPPO A7,9 is the slimmest smartphone in the A-Series. At the same time, it is also the lightest smartphone in the range, weighing just 172 grams. The back is made of shatterproof glass. In order to also meet optical requirements, the smartphone is available in the colors Lightening Black and Unicorn White.
The display with a screen diagonal of 6.4 inches has a resolution of FHD + (2400 x 1080 pixels). The screen takes up 90,7 percent of the front. The AMOLED display type ensures particularly strong colors and an almost infinite contrast. Up to 16 million colors can be displayed. OPPO specifies the maximum brightness of the panel as 430 cd / m². Under the display, hidden from the naked eye, there is an in-display fingerprint scanner that unlocks the smartphone in just 0,32 seconds. The display is protected by the particularly scratch and shatterproof Gorilla Glass 5.
Economical MediaTek processor
Many of the OPPO A-Series models are based on chipsets from MediaTek. So also the OPPO A91, which has installed the MediaTek Helio P70 mobile processor. The 2019-core processor, released at the beginning of 8, is in the mid-range segment. The cores are divided into a performance cluster with two Cortex-A73 cores and a power-saving cluster to which the remaining 6 Cortex-A53 cores can be assigned. All cores clock with a maximum of 2.1 GHz.
An ARM Mali-G72 MP3 GPU joins the CPU. The memory equipment includes an 8GB LPDDR4X main memory and a 128GB data memory. On the software side, the in-house ColorOS is used. You don't have to worry about missing Google apps. OPPO works closely with Google. This is also shown by the Google Widevine L1 certification, which makes it possible to stream Netflix in HD. An update to Android 10 is considered safe.
If you want to compare the performance of the Helio P70 with a Qualcomm chipset, you would have to use the most recently released Snapdragon 600 models. The MediaTek processor does not come close to the performance of the Snapdragon 700 series. This is particularly evident from the gaming performance. Experience has shown that the MediaTek processor struggles in games like PUBG. OPPO's Game Boost 2.0 mode, however, promises to improve the frame rate stability even in demanding games. In PUBG, the frame rate stability should even increase by 55,8 percent.
Still, the OPPO A70's Helio P91 isn't a bad chip. The processor is considered economical and conserves the battery. LTE mobile communications are extensively supported by the bands commonly used in this country. Other transmission protocols are Dual-AC WiFi (802.11 a / b / g / n / ac) and Bluetooth 4.2. The position is determined using GPS, A-GPS, Beidou and Glonass. NFC is available even if the feature is not listed on the OPPO A91 product page. A test will have to show how the Helio P70 will ultimately perform in the OPPO A91.
48 MP quad camera
The rear camera system is made up of four different sensors. The main sensor has a resolution of 48 MP. OPPO does not reveal exactly which sensor this is. The product page only speaks of a sensor with "4-in-1 pixel combination technology", which in turn speaks for a Sony IMX582 or Sony IMX586 with Quad-Bayer technology. With this technology, neighboring pixels are combined into one pixel. This reduces the image resolution to 12 MP, but ensures a higher dynamic range and better low-light shots.
The second sensor has a resolution of 8 MP and uses a 119 degree ultra-wide-angle lens. The other two auxiliary sensors resolve with 2 MP each. This is a camera with a macro lens and a monochrome camera. The OPPO A91 records videos with a maximum resolution of 1080p and 30 frames per second. The image stabilization is done electronically (EIS). Various image enhancers are available within the OPPO camera app. The front camera has a resolution of 16 MP.
VOOC Flash Charge 3.0
Of course, the “VOOC” fast charging technology should not be missing from this OPPO smartphone. VOOC Flash Charge 3.0 charges the OPPO A4050's 91 mAh battery to 30 percent in just 50 minutes. It takes about an hour to fully charge the battery. The matching VOOC quick charger is included in the scope of delivery. Contactless charging is not supported.
