  1. 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

    1. 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 specifically designed for this purpose) and get fresh UV-activated glue for the rebonding process. 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 living with the one crack running diagonally across my display, as it doesn’t prevent the 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.

  2. Hello,
    I have the same Question. My screen is cracked as well.
    I just want to change the front screen.
    Is it enough to disconnect the touch cable from the motherboard after removing the two screws that secure the metal plate?

  3. I have the LeEco Max 2 phone, which comes with 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 identical in every way to the S3 Pro. I want to know if they’ve installed a larger 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!

  4. 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?

  5. 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?

  6. 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.

  7. 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

  8. 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.
