In the last few hours, some Samsung Galaxy Z Fold 4 owners have been complaining about their cell phones. As they themselves report, the Galaxy Z Fold 4 does not open completely, which causes the internal screens to break.
According to Tech Radar, the problem must be caused by a design flaw in the phone's hinge. Remember that, since the launch of the Galaxy Z Fold 2, Samsung cell phones have been covered with small brushes inside the hinge mechanism. These serve one main objective: to eliminate dirt and possible debris, to ensure that the mechanism always works perfectly.
However, the problem is that the adhesive that holds the brushes is coming off on some cell phones, as explained by the same source of information. This possibly causes the adhesive to stick to the mechanism and make it more difficult to open the Galaxy Z Fold 4 fully.
It is possible that the origin of the problem is related to overheating issues

Regarding this issue, a Reddit user reveals that he has reported the problem to Samsung. However, he himself claims that the South Korean brand refused the repair request. Alternatively, the cell phone owner tried to repair the cell phone himself. After the publication made by this user, some responses followed that reported identical situations.
Although there is no official confirmation from Samsung about this problem, it is believed that the reason why the stickers have come off is related to overheating issues (via Tech Radar).
So much so that a redditor says that his Galaxy Z Fold 4 never opened as expected since it was “near a hot tub”.
This problem may happen with other Galaxy Z Fold phones
Apparently, it is not just the Galaxy Z Fold 4 that is subject to these types of problems. On the same social network, Tech Radar reveals that several users have already complained about the same situation. One of them reported that the screen of his Galaxy Z Fold 3 had even broken. Based on the user's words, it would even be possible to see bits of adhesive on the hinge.
As for the Galaxy Z Fold 5, there is a possibility of similar problems occurring. The same source of information reveals that users are already complaining on the Samsung community forum about problems related to the hinges.
