Selfie Expert Camera

The OPPO F1s is dubbed as Selfie Expert because it packs 16-megapixel camera with f/2.0, 1/3.1″ image sensor size, aperture of f/2.0 on its front facing camera. Now you can take better selfies because it allows more light to enter the camera lens and it enhances the image even if you are in a low-light condition areas. The camera app is also easy to use, and it even supports selfie panorama so it’s easy to take groupie pictures and beauty 4.0 mode for that natural looking shots.

Running multiple apps on F1s is no problem, it can do multitask so no need to worry about it slowing down. With Mali-T869MP2 graphics that supports OpenGL ES 3.1, OpenCL 1.2 and DirectX 11.1 you can play some good games with this device.

Some of the games we tested are Need for Speed, Mortal Kombat, Modern Combat 5, NBA 2K16 and Plants vs Zombies.

It runs on ColorOS 3.0 which is OPPO’s custom ROM of Android. the UI is simple to use with vivid colors and flat icon similar to what iOS use.

Some of the cool features of ColorOS are Theme Store where you can download free themes to personalized your F1s, and Lockscreen magazine, where you can subscribe and get this awesome lock screen wallpaper every now then, so everytime you press the power there’s new wallpaper and you can also scroll to the left of the screen to see the gallery. There’s also Eye Protection, Gesture & Motion, and Backup.

There’s also App Permission Management where you can secure your apps, SMS, Contacts from unauthorized access.


  • Good 5.5-inch display great for playing games
  • 4GB RAM keeps the phone multitask an easy task
  •  Graphics are good on games such as Mortal Kombat and Modern Combat 5
  •  ColorOS 3.0 runs well
  • App Permission Management is a cool feature

Not Good

  • Not so good – Still on older version of Android 5.1 Lollipop
  • No news on Android 7 update


The F1 Upgrade supports 4G LTE on its dual SIM card, it comes with a triple tray, this means you can use both SIM card slot and use microSD card slot for additional storage which is great since now you can have both Smart and Globe on this device.

Making calls on this device is great, no dropped calls and the speaker is loud enough to be able to listen and understand the conversation. While the SMS app is simple and clean so you don’t need a 3rd party app for this. Data connection is no problem if you have both Smart and Globe on you SIM.


  • Dual SIM support not hybrid
  • LTE connection
  • Simple and easy to use Phone and SMS app
  • Wi-Fi connection
  • Bluetooth 4.0

Not Good

  • No 700Mhz band
  • No NFC


The F1s Upgrade comes with 3075 mAh non-removable battery, based on PC Mark work 2.0 battery test it scored 5 hours and 9 mins. But based on our personal use as our main phone for almost 2 weeks now we did get an average of around 7 hours before we need to charge it again. Charging it takes a while so better bring along a powerbank with you so that you can charge anytime you need it. Too bad it does not support VOOC fast charging feature that is found in F1 Plus.


  • Good Battery life for normal daily use
  • Micro USB port, easy to charge
  • easy to find a replacement of micro USB cable for charging

Not Good

  • No VOOC fast charge support
  • Slow charging
  • Battery tends to drain faster when used as gaming device

Review Summary

The OPPO F1s Upgraded is really a device to have for those who love to takes selfies and for people who want a good and dependable smartphone for daily use. With its bright 5.5-inch display, it’s great to play games while commuting and watching your favorite TV show via iFlix is enjoyable and you can even download it offline and not to worry about storage getting low. The Triple tray is another notable feature of F1s that you seldom find on other brands since most of smartphones have hybrid sim card tray.
