normally these problems occur due to the tempered glass screen protector. Samsung does not manufacture this type of protectors directly, but they are manufactured through third parties. In addition, the screen without edges or "edgless display" has curvature and prevents the protectors fix properly on the edges of the terminals.
Adjust tactile sensitivity
Before running to throw away that tempered glass protector try the following. Go to Settings / Display / Navigation bar / sensitivity. In the latter option, he says "very sensitive". If you still have not solved your problems, you know what is next.
Remove the tempered glass protector
In the event that you have not yet succeeded in correctly responding to the touch of the device, you will have to remove the tempered glass. For this the first thing you have to know is that it is recommended that you go to a place where there are professionals who retire with guarantees. It may be the case that removing the glass incorrectly, we will damage the terminal screen and it will be much more expensive.
In the event that you try to withdraw by your own means follow these steps:
- Use a dryer to heat the protector for about 15 seconds and can be removed more easily
- Use a prong or similar plastic element to lift the protector by the corners
- Once you have raised the edge of the protector, insert a letter next to it to open space.
- Remember to do this process in a slow and careful way and when you finish clean the possible remains of adhesive that may remain on the screen. We leave you a video in case you have any questions.
