Remove the SIM card tray.
The SIM card tray with a T shape can install two Nano SIM cards.
In order to remove the display assembly, we need to heat the display edges with a heat gun.
Open the display assembly a bit with a suction cup. At the same time, insert a guitar pick and slide it along the edges to remove the display.
Be careful. The touch cable is still connecting to the motherboard.
Remove two screws securing the metal plate. You will be able to disconnect the cable.
Here’s the LeEco Le Pro3 display assembly.
The LeEco Le Pro3 features a 5.5-inch full HD (1080p) display. The touch chip is from Synaptics, and the model is S3320A.
Under the screen, there is a metal plate used to isolate the screen and the fuselage. The metal plate is covered with a layer of thermal insulation foam. It is used to reduce the influence on the display by the internal temperature.
Remove all screws securing the metal plate.
There is a screw is covering by fragile stickers. If you damage it, you will void the warranty.
Here’s the metal plate.
With the metal plate removed, you can get access to the battery, camera, speaker, and motherboard.
Disconnect the battery connector from the motherboard.
Pull out two adhesive tapes. The battery can be removed.
LeEco Le Pro 3 comes with a 3.85V, 4070mAh Li-polymer battery.
The bottom board integrates a vibration motor, a microphone, a USB Type-C port, and a speaker. The microphone and USB Type-C port are around the silicone seal to prevent dust from entering the fuselage inside.
From this picture, we can see that most of the main chips are covered with the metal shield.

Hello, my screen cracked. Do you think it is possible to remove the screen from the LCD? Or is it better to buy a full LCD replacement? Thank you
The display’s digitizer glass is fully laminated to the LED display. You will need to try to fully remove the UV bonding glue from the LED (which can be done much more easily and safely with a chemical glue removal formula made for the purpose) and get fresh UV-activated glue for the rebonding process. Suffice it to say, it would really be easier to get the pre-bonded assembly and just reinstall it that way. Just because it can be done doesn’t mean it will be easy, or free from flaws or damages in the UV glue removal or rebonding process.
I am just living with the one crack running diagonally across my display since it doesn’t prevent touch function or straight-on viewing. I bought the glue and was going to buy the digitizer, but seeing the result of another inexperienced “repair tech’s” efforts, I decided to wait until I was desperate.
So giving more heat to it won’t make it easier to separate? I kind of mistakenly only bought the screen and not the LCD and it has already shipped and I didn’t want to waste my money.
what kind of solvent would I need to use to separate them?
Hello,
I have the same Question. My screen is cracked as well.
I just want to change the front screen LCD.
Is it enough to disconnect the touch cable from the motherboard after I remove the two screws securing the metal plate?
My Screen also cracked. Does anyone know where I can get it repaired or where to get a net display unit?
I have the LeEco Max 2 phone, but it has a 3000mAh battery. I really want to try and put an S3 Pro 4000mAh battery in it. Everyone says it can’t be done, but the LeEco S3 is the same size in every way as the S3 Pro. So I want to know if they put a bigger battery in the S3 Pro or if it’s just a higher-quality battery. I really just wanted to order both and check the size, but I can’t find them anywhere. Help!
If the output voltage is the same, you can try to install it.
I unplugged my LeEco 3 from the charger, and it will not turn on. I have never had this problem before. What do you suggest I do?
My virtual buttons have been damaged and are now unresponsive, and the LED lights are defective. I wanna fix this problem. Can I replace the part myself?
If so, where can I get the parts I need?
Hi, David,
The consensus among reviews of the LE Pro 3 is that it has FM radio capability. However, I do not see any chip mentioned in your article that supports FM radio. In your teardown, did you find any such chip? I’m trying to build a kernel and support into Lineage-15.1 that supports FM on this device, but I don’t know which chip does the FM and so which driver and firmware to build in.
Thanks!
Warren
I checked the specifications of LeEco Le Pro 3 from its official website, the phone do not support FM redio.
You won’t be able to. I tried it. The connector for the battery in the Leeco Pro 3 is bigger, and it won’t connect with the S3.
Hey,
I have had a LeEco Pro 3 AI for 2 months. I have had a focusing problem, and all my pictures from 10cm are blurred.
I bought the camera from the internet to change it, but first, I’m not sure it’s a hardware problem.
Second, it seems from your explanation that I have to break my screen to access the camera.
Maybe you know about this problem and how to fix it.
There is another way to access the camera like all other phones?
Thank you for your help
Hi David, my LeEco Le Pro 3 phone has lost its GSM signal, I have tried a new SIM card. But nothing seems to work. Can you shed some light on it?
Thanks
Please, how do I fix the screen overlay issue with my Leeco Pro 3 AI phone?
I have tried all I know and failed. I installed a button unlocker app and it didn’t work. Please help.
Where can I purchase a replacement selfie camera module? How do I remove the IR filter?
