Introduction

Use this guide to replace a cracked or broken screen on a US version Samsung A03s.

For this guide we will be using a refurbished screen with the frame preinstalled.

Before beginning this repair, be sure to inspect your new screen to see what small components come installed. Some steps in this guide can be skipped if your using a screen with components preinstalled.

Note: In this guide we will be transferring components to a new screen and frame assembly. If your screen does not come with the frame preinstalled then this procedure will not work.

Note: The US version of this phone is slightly different than the international version. In general, you can still follow this guide, but some components may look slightly different.

Note: For this repair we will be removing the battery and transferring it to the new screen assembly. If your battery is swollen, take appropriate precautions. Before opening your phone, discharge your battery to 25% or lower. The battery could catch fire and/or explode if punctured.

    • This cover has a series of plastic clips that attach it to the frame. Use your opening tool to gently pry the plastic back cover off.

    • Be careful inserting your opening tool near the power button. This button contains a fingerprint sensor with a ribbon cable that’s attached to the back cover. Do not cut this cable while removing the back cover.

    • Use heat and/or isopropyl alcohol to remove vibrate motor

    What is that yellow ribbon cable at the bottom to the side of the vibrate motor? I ordered a new screen and front frame, and while I was transferring things I accidentally punctured my battery. I had to get rid of the back frame, and it still had that part in it. I was too afraid of trying to get it out with the battery sizzling and sparking. The replacement front frame I bought doesn't have that in it, and I can't find it sold anywhere. Please someone help.

    Yeah so that's for a slightly different model, apparently they made the A037U and the other one, and I live in the US so i accidentally bought the international version..

  14. xeSYDhrI5nKNr2wH

    • Use heat and isopropyl alcohol to remove the battery.

    • Be careful to not puncture the battery while removing it.

    • There's a lot of adhesive under this battery and it can be tricky to remove. You can slide a thin plastic card underneath the battery to help break the adhesive.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Actually you guys are making it more complex and difficult than it needs to be or should ever have to be because I've repaired hundreds of Samsung Galaxy a03 s's and all Samsung Galaxy phones for that matter and the way you're going about in depth in detail and specific on a complete breakdown is too complex to be quite frankly honest with you you don't need to do all of this you're doing more work than what is really there honestly.

Are you going to offer the more simple solutions or no?
