Samsung Galaxy Z Flip and Motorola RAZR clamshell smartphones are completely unstable to cold (6 photos)

Promotion of emerging smartphonesthe screen is fraught with numerous technical problems, which is characteristic of any new technology. However, developers should solve technical issues at the stage of creating devices, and not identify users in the process of operating new products. Both models of smartphones made in clamshell form factor: Samsung Galaxy Z Flip and Motorola RAZR were, according to consumers, not ready for temperature extremes.

Smartphone Motorola RAZR after seven daysthe operation got a crack at the bend, and the plastic coating at this place peeled off the screen. According to the owner, the smartphone was not subject to mechanical stress and was not dropped. In this case, a crack on the screen cover was detected after the smartphone was used at a temperature of -2 degrees Celsius, and then brought into a warm room. The deformation did not appear immediately, but the next morning.

Similar damage was found in the Galaxy ZFlip. Moreover, the Samsung’s device had the screen in this state immediately after unpacking and first bending the screen (the smartphone is delivered in expanded form). When the smartphone was first closed, the owner heard a characteristic crack of glass and saw a crack. According to the user’s version, the smartphone received “hypothermia” during transportation, and then could not withstand the temperature difference. Samsung has promptly replaced the screen on the same day.

The polymers present inthe coatings of the screens of both models do not work very efficiently under variable temperatures, gradually reducing or increasing their strength characteristics, which leads to the destruction of the coating.
