FAQ:
Q: I see a black dot in the middle of the screen of my Samsung Galaxy S4 that looks like moisture. When I press on the edges of the glass the black dot disappears or shrinks.
A: The newly mounted glass is too close! The glass is touching the LCD below. This is the reason why we apply a secondary layer of double-sided tape to the sides of the phone. If you have this problem even after applying the extra double sided tape then consider applying a third layer, this however may impair the touch sensitivity. You can also consider reheating the top and bottom of the front glass and fix it well, this sometimes provides enough tension to stop the glass from touching the LCD. If you exhausted these options then you can consider gluing the new glass with LOCA (liquid optical clear adhesive). Check out this link: https://www.youtube.com/watch?v=MfUy3...
Q: During calls the screen of my Samsung Galaxy S4 stays black even when I hold the phone out in front of me.
A: Something is blocking your proximity sensor! Perhaps some double sided tape is out of its place. Remove the glass and check if the sensor is blocked.
Q: The screen of my Samsung Galaxy S4 sometimes freezes, when I reset the screen using the power button it works again.
A: The glass is touching the LCD underneath, this usually happens when you press hard on the glass. This can cause the touchscreen to short-circuit. The reason that this can happen due to the absence of the LOCA (liquid optical clear adhesive) that is used to glue the glass to the LCD in an original phone, after performing the repair. These problems only arise in some cases. The solution is to not press hard when operating the phone. To completely fix this problem you can consider using LOCA to glue the glass to the LCD.

Q: The touchscreen of my Samsung Galaxy S4 is less sensitive.
A: In some phones this is a side effect of applying extra double sided tape along the edges. It indicates that the glass is too far away from the touchscreen. Usually this is avoided because in the Video the tape is only applied for 75% of the length of the sides. This results in the glass having a subtle curve. This curve is designed so that it minimizes the risk of the glass touching the LCD. at the same time it brings the glass closer around the top and bottom of the screen, increasing sensitivity there. You could try removig the extra double sided tape, thus bringing the glass closer. However this is risky because the glass may touch the LCD while operating the phone. If the extra double sided tape is removed then the phone should be operated without applying too much force. However, if this causes the glass to touch the LCD while operating the phone then you will have to use LOCA to glue the glass to the LCD. Check out this link: https://www.youtube.com/watch?v=MfUy3...
