After Asus , Oppo had launched a new series of smartphone centered at camera named “F series”  launched in January. They also tried to give this series a premium look in budget. Recently launched its camera centric smartphone called the F1 'selfie expert' in India at Rs 15,999 (246$). Our editor was very exited about this phone so  we spent a lot  time with the smartphone to find out if it just looks and feels premium or does it offer something more. Here is our detailed review.
Look and Design
Oppo had completed their goal by  giving F1 a premium looking design that comes with an aluminium body along with plastic frame. The back panel of the smartphone, which is non-removable, packs the 13MP primary camera along with the LED flash, speaker and very big  Oppo logo. Looking at its design it can be said that Oppo had tried to give it a classic old look. The Oppo F1 has various colour  choice as it available in Gold and Rose Gold, however the choice is only with back ,front face will be white in both cases. The Dual-SIM tray is placed on the right . The most ridiculous thing is that it is  hybrid type, so you'll have to choose between a second SIM and a microSD card.
We love the fact that, the company had managed to maintain its weight with  around 134g, it's very lightweight. The phone fits very well in your palm, with a comfortable. The overall classic design design comes after very long time in any smartphone. But this design looks great give it premium look.
Display
Coming to the display, the phone has 720p IPS LCD display but we expected 1080 p display but it does a good job. While the colour reproduction for the price is good, phone perform well in night but in day light it has slightly low brigtness. Also, the viewing angles could have been better. Apart from this the touch was fairly responsive and the images appeared fairly sharp.
Specifications
Oppo F1 one of the few smartphone available in the market which comes with  new octa-core SoC from Qualcomm which is very similar  to the now-common Snapdragon 615 processor, but runs at a slightly greater speed. It's the lower-power Cortex-A53 cores that run at 1.2GHz. Other specifications involves  3GB of RAM, 16GB of onboard storage, support for up to 128GB microSD cards, and 4G VoLTE on band 1, 3 and 40. In terms of connectivity, it packs Wi-Fi b/g/n, Bluetooth 4.0, USB OTG, FM radio, and GPS but there is a lack of NFC.
Software
The Oppo F1 runs an Android Lollipop and runs on one of the best custom functional fork called Color OS (2.1). We are not happy with lollipop as we expected marshmallow.
 It's a single-layered interface that can be customised with different effects and themes. Oppo also packs  some useful apps such as O-Cloud, which lets you back up your contacts and messages ;Security Center for monitoring data usage, freeing up memory etc.; Kingsoft Office for working on documents and spreadsheets; and Theme Store for customising the phone.
Camera
Coming to main attraction of phone . The phone has a 13MP primary camera that is capable of taking some very nice shots. Front camera give crisp detailed image in day light but in low light it gives a little shakey image with lack of little details but overall low light performance is better than phones like  Lenovo Vibe K4 note. The quality of  low light image increase by HDDR mode.
Coming to main highlight of this smartphone that is 8 megapixel front camera for which company said it the salfie expert. The company had showed that they are mainly concentrated at front camera by making its aperture wider than rear. It manages to capture fairly detailed selfies under natural and artificial light while the quality dips a bit in low light.
Company had added some new features like palm shutter which help you to take pics by looking at tour palm and "Beautify" filter to take care of those skin blemishes. Apart from the usual modes, the camera app in Oppo F1 is capable of shooting GIFs, slow motion videos, audio photos, double exposure photos etc.
Performance
General performance of Oppo F1 us brilliant. The best part which is very rare in smartphone is smooth multitasking. There is no heating problem with phone while using 4g and general apps but during continues video play it become slightly warm. We don’t want to take this problem seriously.
As expected the there is huge jump in AnTuTu bencmark as it gave us a score of 35,530. On hand performance , as we had told earlier , is brilliant. We did not face any problem in playing heavy games  like Asfalt. We slightly disappointed that company had given 2GB RAM instead of 3 GB. We did not write much about performance because it is solid performing phone .
Battery
This phone packs a battery of 2500mAh which ends up to 8 hr 40 min in our video loop test. During general use battery works good even 4G and it totally lasts in about 2 days . Sadly there is no quick charging feature so you have wait a long time specially in last few percentage.
Conclusion
General performance is good including camera, and both the front and rear cameras deliver good quality in most lighting conditions. Battery life is also solid, given the moderate capacity. So its price is good talking all this feature.
