OPPO F1s teardown_fonearena-02

OPPO launched its selfie-centric F1s smartphone in India last year for Rs. 17990. We had seen several versions of the smartphone since then, including a Rose Gold version most recently. Even though this has a familiar design as some of the smartphones with a unibody design, there are a lot of components that go into making the device what that might not be revealed on a regular specs sheet. We did a teardown of the device to see what it packs on the inside. Let’s take a peek.

We started off by switching off the device and removing the dual SIM Slot which also houses the micro SD Card slot. To remove the back cover, first we removed the bottom plastic part to reveal the metallic screws holding the back cover. Then we removed the four screws holding the back cover. Then we pry opened the back cover using a slim plastic tool.
The back cover houses the cut outs for the camera setup, LED Light and Oppo branding. At the right side opening for the SIM card slot and power key. At the left side we have the volume rocker. And at the bottom there are cutouts for micro USB and speaker holes.

The back cover has a metal sheet on the top of the plastic back cover. Even the edges of the back cover are made of plastic.

There are the five screws holding down the loudspeaker assembly. we removed them and disconnected the the ribbon cables connected to the 3.5mm jack assembly. The 3.5mm audio Jack circuitry consists of the micro USB port and primary microphone. Next is the loudspeaker with metal contacts.

The  main logic board is held by 8 screws that need to be removed to remove the protective metal brackets over various ribbon connectors.

Now the battery can be disconnected by pulling the tab. The battery is rated at 3075 mAh. It is made by Oppo itself. Now we can disconnect all the ribbon cables connected to the main logic board to remove it from the phone body.

Now the primary camera and selfie camera can be removed from the logic board. The front facing camera is an 16MP camera with 1/3.1″ sensor and f/2.0  aperture. The primary camera is Sony IMX258 13MP 1/3.06-inch Exmor RS sensor with 1.12-micron pixel size, f/2.2 aperture. We then removed the metal brackets over the processor and other chips in the main logic board. Lets take a closer at the various components now.

We give the Oppo F1s Note a reparability score of 7/10. Finding how to open the phone was a bit tricky. Most of the ribbon cable connectors are covered by metal brackets which is a welcome move to prevent connectors getting loosen from accidental drop.

Please note that teardowns will most definitely void your warranty so if you are planning to do the same on your device, keep that in mind.
