Before, our colleagues accidentally broke an X20 Plus, the entire screen was fragmented, and the phone was not peaceful. Then the problem came. Although the mobile phone was broken, it was a trivial matter, but inside it was still not there. Little things, it's a bit tricky to copy the internal data when the screen is completely out of light.
At this time, we decided to take the curve to save the country by dismantling the existing X20 Plus screen fingerprint version. The replaced parts allowed the X20 Plus to recover. However, to save the colleague's mobile data is only one aspect. On the other hand, we mainly want to meet the embarrassing taste of creating the world's first mobile phone with screen fingerprint unlocking and fingerprint unlocking at the same time.
First of all, the fingerprint version of the X20 Plus screen is a small variant derived from the X20 Plus. We had previously said that the internal structure of the X20 Plus is basically the same as the fingerprint version of the screen. Therefore, we believe that the two models should be replaced. The screen of the mobile phone is theoretically feasible. Secondly, one of the important reasons for replacing the screen is to copy out the data. Therefore, what we need is to install the X20 Plus's complete motherboard with the data directly on the screen fingerprint version of the screen assembly. On top of this, we can do this practically.
First open the X20 Plus which breaks the screen. The dismantling process will not be mentioned here. Unscrew the bottom fixing screw and carefully separate the back cover. Because there is a cable connecting the fingerprint identification on the back, the back cover is loose. Don't worry about direct hard work.
The rest of the process is not shown (interested friends can read our previous X20 Plus and X20 Plus screen fingerprints for detailed disassembly pictures), where everyone mainly focuses on the contents of the red circle, here is the BTB interface for back fingerprint recognition.
Then we put down the X20 Plus first, open X20 Plus screen fingerprint version as a comparison, the dismantling process is the same, but there is no fingerprint recognition component on the back, so when you remove the back cover can be less concerned about some. Here need to mention, because There is no back fingerprint, so the X20 Plus screen fingerprint version is actually thinner by 0.1mm on the overall thickness, and the back cover will be tighter.
Comparing the two models, you can see that the two are exactly the same in terms of the main board (the fingerprint is not removed when the upper metal fixing cover is not removed, and the XBT is disconnected from the BTB), which further strengthens us. We think that the two parts can be used as a common guess. After seeing this, we decided to change it more thoroughly. We will exchange the motherboards of the two machines with the above cameras, and try to see if they can be used normally.
The motherboard is removed, because the sub-board below is completely the same, so the sub-board with the FPC on it do not handle. Here put a X20 Plus screen fingerprint version of the motherboard large map, you can see, in the previous X20 Plus The back of the fingerprint recognition BTB, on the screen fingerprint version has the same reserved position, but there is no welding element, directly blank, this is because the use of screen fingerprint recognition as a substitute. This is even more shows that both the motherboard design is actually It is almost exactly the same.
Next is the highlight of the test. The X20 Plus motherboard is installed on the fingerprinting board of the X20 Plus. The installation process is not difficult because the two are exactly the same. Reconnect all BTBs and install the RF cable back to the original In order to facilitate adjustments, our back cover is not covered and not completely installed.
By turning on the power contact on the side, it is found that the screen can be lit normally and the touch operation is also completely free of problems. We have performed operations on all the components involved in the replacement, including photographing, voice, call and network connection tests. The installation can complete the task perfectly.
Next we are ready to go further and add the X20 Plus's fingerprint identification back cover to this assembler to see if we can coexist with the two fingerprints.
After experimenting, this idea did not work. For the first time, I directly connected my fingerprint identification line on the back in the boot state. The phone prompts for fingerprint identification abnormality. We tried to restart the phone after connecting and found that we could enter the fingerprint entry interface. Actually unable to operate, touch back fingerprint identification button does not have any reaction.
Although the design and components of the two phones are highly coincident, they are completely incompatible in terms of fingerprint recognition. Because the motherboard of the X20 Plus is used, the actual system of the mobile phone is a normal version of the X20 Plus, and the installed X20 cannot be called. Plus UD's screen fingerprinting component, but after connecting back fingerprint recognition, because of the conflict between the two components, the fingerprint recognition on the back can not be used.
So the end result is that our goal is half completed. The task of helping colleagues to export data is completed, but the desire to build the first mobile phone with facial recognition + screen fingerprint recognition + back fingerprint recognition is shattered. Ah. In fact, vivo is a kind of machine. It is still very interesting to directly add new features. It can bring users newer technology experience in a shorter period, but how to deal with the same user The aesthetic fatigue of the prototype may be a problem that vivo needs to consider.
