Design and Build of Oppo K1
Oppo K1 was launched in the Chinese market in October last year. The back panel of Oppo K1 comes with a gradient design. We have the Astral Blue variant available for review which is quite striking. Apart from this, the Piano Black variant of Oppo K1 has also been launched. Its 3D injection-molded back panel gives a cool effect when exposed to light. Fingerprints fall easily on the back panel. The arrangement of buttons and the build quality of the phone is quite good.
On the left side of the phone, the SIM-tray (two nano SIM and one microSD card) has got a place. Oppo K1 Dual comes with 4G VoLTE support. The speaker grille, Micro-USB port and 3.5mm headphone jack are at the bottom of the phone.
Oppo K1 smartphone has a 6.4-inch full-HD + (1080×2340 pixels) display, Corning Gorilla Glass 5 has been used for screen protection. The in-display fingerprint sensor has got a place for security. Let us know that this phone of Oppo brand has amoled panel.
Oppo K1 has a waterdrop display notch. The selfie sensor has got a place in the notch, due to less space, the notification LED is not present. As usual, the screen guard will already be on the display. There is a dual rear camera setup on the back of the phone. In the retail box, you get a silicone case, SIM eject tool, micro-USB cable, 10W power adapter and headset.
Specifications and features of Oppo K1
The octa-core Qualcomm Snapdragon 660 processor has been used in the handset, whose speed is 2.2 GHz. This chipset is used by Realme 2 Pro (review) and Xiaomi Mi A2 (review) took place. Only one variant of Oppo K1 has been launched in India. With 4 GB RAM and 64 GB storage variants. The phone includes dual-band Wi-Fi 802.11 ac, Bluetooth 5.0, USB OTG, GPS support. The smartphone has compass, accelerometer, ambient light sensor and gyroscope sensor. FM radio is not provided in the handset.
Oppo K1 Out of Box will run on ColorOS 5.2 based on Android 8.1 Oreo. It is expected that during the Mobile World Congress 2019 (MWC 2019), the company can unveil some new Oppo smartphones with ColorOS 6. Oppo K1 comes with Hyper Boost tech for better gaming performance. Apart from this, you will also get many additional features like Smart Sidebar, Smart Scan and ORoaming.
Apart from system apps, Oppo K1 does not have many pre-installed third party apps other than Facebook. You will get to see many ads because of the default browser and Oppo App Store. You can disable App Store spam, but disabling this feature in the browser will still cause problems. Similar problem was also seen in Oppo A7.
Oppo K1 performance, camera and battery life
We used the handset for several days but we did not face any problem. The display of the phone is quite large, due to which you may have some problem in using the smartphone with one hand. Despite the glassy texture on the back and sides of the phone, the phone does not slip from the hand. The touch response of the AMOLED display is also quite good.
ColorOS is also quite smooth and due to the 4 GB RAM, the phone runs smoothly. Talking about the phone’s in-display fingerprint sensor, it is not as fast as the standard capacitive sensor. So touch your finger on the sensor properly. The face recognition feature given in the phone works fast. With the help of screen brightness in low-light, it easily detects your face.
The 6.41 inch display is good enough for watching videos. The speaker sound was quite loud while watching YouTube videos, but while playing the PUBG Mobile game, it sounded a bit slow even at full volume.
There was no problem of any kind while playing heavy games on Oppo K1. With Asphalt 9: Legends on high graphics setting and PUBG Mobile on medium graphics, both the games ran quite smoothly. We did notice that the phone does not get too hot even after playing for more than 30 minutes. Benchmark numbers also indicate that this phone of Oppo brand runs games and apps well. Oppo K1 has scored 1,28,852 in the Antutu benchmark.
Talking about the camera, Oppo K1 has a dual camera setup on the back. The primary sensor is 16 megapixels and the secondary sensor is 2 megapixels. There is a 25-megapixel selfie camera on the front panel. First thing about the selfie camera. The selfie sensor is equipped with Artificial Intelligence (AI) beautification system. Users can also set the beautification level manually if they want.
Image quality is quite good in daylight without beautification. You can blur the background in selfies, but we found that edge detection doesn’t work properly. Selfies taken in low-light also came out quite well. The front camera comes with Auto HDR support. The 16-megapixel rear sensor captures good pictures even in low light. The 2-megapixel rear sensor is used only for edge detection when shooting in portrait mode.
In portrait mode, the camera takes some time to focus when there is enough light. Features like Panorama, AR Stickers, Expert Mode will be available in the camera app. Talking about video, Oppo K1 is capable of recording videos up to 4K resolution. Image quality was better at 1080p resolution. 3,600 mAh battery has been given to bring life to Oppo K1. The phone provided 12 hours and 36 minutes of backup in our HD video loop test. The Oppo K1 Wook does not come with fast charging support, but you will get a 10W power adapter that will charge your phone fully in 2 hours 30 minutes.
Oppo K1 is the only smartphone in this price segment to come with an in-display fingerprint sensor. The price of this handset in India is Rs 16,990. We liked many things in the phone but there are some things that could have been better such as a USB Type-C port could have been given in the phone. Its build quality could have been better. Low-light camera performance could also have been a bit better. Apart from this, we hope that the company in its upcoming ColorOS version will solve the problems that are being faced in many apps.
Equipped with better gaming performance, sharper display, selfie camera, better battery life and in-display fingerprint sensor, Oppo K1 is a great option in this price segment.
