2. Put a new double-sided tape on the frame of the case. Don't use the old glue, it's lost its stickiness: 3M 9448A or Tesa 61396.

• 🔋 Forgotten battery disconnected – if you put together a phone with the battery turned off, it won’t turn on and you’ll have to disassemble it again.

After assembly, turn on the phone and check:

• 🎨 Color rendering — compare it to another device (for example, on a white background) and non-original screens often have a bluish or yellowish tint.
• ☝️ Touchscreen sensitivity – test multi-touch (simultaneous touch at multiple points).
• 🔦 Lighting – are there no dark spots or uneven glow in the corners.

💡

If the screen is running after the replacement, but the touchscreen is floating (touching is not where you pressed), the problem is a faulty plume or controller. 90 percent of the time, reconnecting the plume helps. If not, a board diagnosis is required.
