Solution for Samsung S7edge LCD Red line repairing

Many S7 edge mobiles have red line on screen around front camera. 


1. Why is the red line appearing?
The reason for the red line is that due to Samsung's design flaws, the screen flex cable is easy to loose to lead the red line appeared. This red line normally appears around the front camera as the screen flex cable is on the side of it. The process of repairing the red line is to insert a small card into the connection of the screen cable behind the camera and press the screen cable with the filling method to make it firm. It can eliminate the red line. It could use card cut to the long strip as shown in picture 2, and it can be inserted into the position shown in picture 1. If the red light did not be repaired, please adjust the position, and increase the width of the card, and the thickness. It can be perfectly repaired.

5.Q&A:
 
1. Why this red line still there, I adjust many times after inserting in the place you pointed?  Is there any way to repair the red line?
Crystal: Maybe the small card is not suitable for.
 
2. The red line appears after changing the external screen, but it does not always exist. Can I fix it?
Crystal: Can repair. We need to repair it before this red line did not be fully displayed and it is repaired first.
 
3. Why the returned function of home key or touch did not work by this repair way? 
Crystal: The cable is not connected well. You can remove it and reload all the cables. Press firmly, don't loosen.
 
4. Always ignore this red line. What will happen?
Crystal: This line will slowly become thicker, or more. I can’t fix it anymore.
 
5. In this way, will it recur after repair?
Crystal: The possibility of recurrence in the same location is not great. This pad is the screen cable that repairs the camera. If it is in another position, there is basically no solution unless the screen is removed and repaired. And this repair is still conditional, hold down can disappear, do not press according to this situation, the repair probability is 100%, the repair is not the location of your paper is wrong.
