What would you do for a OnePlus 2? We're a little shy, so we asked OnePlus if we could skip the dance party and flashmob contests, and they happily sent us a unit to rip apart. Kudos for their bravery.
Self-styled as the "2016 flagship killer," the OnePlus 2 steps into the Android phone market with circus-clown-sized shoes to fill. After the OnePlus 1's lackluster repairability score last year, we're hopeful that the new model brings some refinements and improvements for repair-minded folk like ourselves.
Follow along as we disassemble OnePlus' latest offering and see if they'll "never settle" for a 5/10 in repairability again.
Here are OnePlus 2 different ways to keep up with the latest teardown news: follow us on Facebook, Instagram, or Twitter!

The OnePlus 2 will need a bit of brawn to beat the big boys. Let's check its specs:
-
5.5-inch IPS display (1920x1080, 401 PPI)
-
13 MP main camera, 5 MP selfie cam; up to 4K video; 720p slow-mo at 120fps
-
64-bit Qualcomm Snapdragon 810 processor with 1.8 GHz Octa-core CPU and Adreno 430 GPU
-
3 or 4 GB LPDDR4 RAM
-
16 or 64 GB eMMC v5.0 storage capacity
-
802.11a/n/ac Wi-Fi, Bluetooth 4.1, GPS/GLONASS, Digital Compass—and USB-C connectivity (a pretty snazzy cherry to top off these features)
-
-
-
Meet the new "alert slider." OnePlus has developed a "volume" control for your notifications, throttling to various levels of priority with a single switch.
-
On the back of the phone, we find the highly touted six-element, 13 MP, f/2.0 rear-facing camera, flash, and laser autofocus blaster.
-
Is that a USB-C port we USB-see?
-
One of the first mass-market smartphones with a USB-C port, the OnePlus 2 gets the benefit of a reversible connector—though it seemingly lacks the faster charging and data transfer abilities we'd hope for.
-
-
-
Like another recent flagship Android phone, the OnePlus 2 lacks external screws.
-
Thankfully, OnePlus has also foregone the use of adhesive for the rear cover, instead opting for plastic clips.
-
We got our hopes up, but prying the case up revealed a solid midframe, no battery in sight.
-
And at least we have access to the dual-slotted Nano SIM tray, no SIM eject tool needed.
-
-
-
With the rear cover removed, we set to work on a vast legion of screws. It's miles better than glue, but there are just so many... Fortunately, our Pro Tech Screwdriver Set is on hand to face down this gaggle of Phillips fasteners.
-
The OnePlus 2 hits back as we find even more screws hidden away beneath rubber covers.
-
We also find a single screw wearing a tamper-evident seal—one that we're pretty sure OnePlus expected would be broken...
-
-
-
Turns out that well-secured midframe is a thin plastic cover—now (minus 18 screws) easily removed.
-
A peek inside reveals the signature red battery and a bit of the motherboard.
-
There's not much left in the midframe cover—just a loudspeaker, and cover lenses for the camera and LED flash. We'll move on to greener and more tempting pastures...

Smartphones today are without a doubt the go-to photography tool (camera!) of choice. That makes the shooters in these smart devices a cardinal comparator. Here's what OnePlus brings against the competition:
-
13 MP, f/2.0 rear-facing camera with Optical Image Stabilization and Dual-LED flash.
-
5 MP front-facing selfie camera.
-
-
-
According to our research, the main camera sports an Omnivision OV13860 PureCel-S image sensor while the selfie camera uses a 5 MP OmniVision OV5648.
-
That rear-facing camera features 1.3 µm light-collecting pixels—the biggest ever in a 13 MP smartphone camera.
-
Taking a closer look with our X-ray vision, we can clearly make out the electromechanical actuators that move the lens, providing that optical image stabilization.
-
-
-
One last component makes up the OnePlus 2's fancy photographer: The infrared laser rangefinder.
-
This component is made up of two parts: an IR LED and matched receiver.
-
The IR LED probably projects a cone of IR light on the subject, which bounces to the receiver. This lets the camera estimate the distance to the subject, and snap the focus to match.
-
-
-
Our always-trusty spudger shows up to detach the handful of cables still keeping the motherboard in place.
-
A few of the many midframe screws served to secure the motherboard—but having dispatched those previously, we're faced with just one more.
-
Screw removed, alert slider up, and—with a bit of prying—the motherboard is out.
-
-
-
Samsung K3RG2G2 LPDDR4 dual-channel RAM, with the Qualcomm Snapdragon 810 layered beneath
-
Qualcomm PM899
-
Qualcomm WCD9330 audio codec
-
Qualcomm PMI8994 Power Management IC
-
RF Micro Devices RF7389EU multi-band power amplifier
-
Skyworks 77814-11 power amplifier module for LTE
-
Qualcomm WTR3905 RF transceiver for dual SIM support
-
Qualcomm QFE1100 envelope tracking IC
-
-
-
And on the reverse...
-
Qualcomm QCA6174 802.11ac Wi-Fi 2x2 MIMO combo SoC
-
Samsung KLMCG8GEND-B031 eMMC 64 GB NAND flash memory
-
NXP TFA9890 audio amplifier

The USB-C port cable is pretty barebones—just a couple of (mysterious) spring contacts, which is good news for repair.
-
It's a little more fiddly than last year's One, but certainly not the Apple standard charging port mess.
-
USB-C is a pretty new addition to the smartphone world, so naturally we took a peek inside.
-
-
-
Under the charging port cable, we strike daughterboard. Eureka!
-
The little foam foundation is the speaker box for that loudspeaker we spied in the midframe.
-
The daughterboard also houses a familiar classic: a coin-style vibration motor. Unfortunately, you'll need a soldering iron to replace it.
-
On the backside we find yet more spring contacts, a microphone, and the soft button LEDs. Like the motherboard, this daughter is a busy board.
-
-
-
It was bound to happen sooner or later—out comes the iOpener to beat down the adhesive that secures the display to the midframe of the device.
-
After a quick spot of heat under the iOpener, the display of the OnePlus 2 is easily freed using a couple opening picks.
-
We finally get a good look at the backside of the 5.5-inch display assembly next to the now-empty shell of the midframe.
-
-
-
On the rear of the display we find the Synaptics S3320A touch controller that governs the touchscreen.
-
We also get a look at what turns out to be a soft home button which sits awkwardly below the very delicate side button cables. This is sure to make replacing the home button more of a hassle than it should be.
-
Keeping pace with Apple and Samsung, the OnePlus 2 features a fingerprint sensor. The FPC1150 touch fingerprint sensor by Fingerprint Cards AB can recognize up to five fingerprints and will read them in any orientation.
-
-
-
OnePlus 2 Repairability Score: 7 out of 10 (10 is easiest to repair).
-
A single (non-proprietary) screw head decreases cost of tools for repairs.
-
Many components are modular and can be replaced independently.
-
USB-C port is on a relatively simple flex cable, not an assembly—it should be an inexpensive replacement.
-
Despite the warning, the battery is fairly easily removed—but still requires disassembly.
-
The LCD and digitizer glass are fused together and must be replaced as a single part; heat is required to remove it from the midframe.

What type of gyro/accel is present? What are the ICs on the camera circuit board - are these OIS gyros?
Is there any NFC hardware present on the phone?

Nope! OnePlus claims that there are currently not enough NFC applications to justify including NFC hardware in the OP2.
Does anyone knows if the Oneplus 2 has the same problem as the 1 has. Is the digitizer also broken even there is even 1 crack in the lcd?
