Last month, we told you that the display on several BlackBerry KEYone units were popping off the phone on impact . At first, it was believed that the screens did not have any adhesive on them to keep them in place. However, BlackBerry Mobile did say that it used adhesive, but obviously one that was not strong enough to do its job. The company said that it would find a better adhesive for use on newly produced units. And that was the last we heard about the matter until now.Yesterday, on its @BBMobile Twitter page, BlackBerry Mobile left a link to a posting made by a member of the BlackBerry Mobile support team. The message relayed the latest information about the BlackBerry KEYone . To insure that KEYone owners have an "outstanding experience," BlackBerry Mobile has taken steps to add extra strength and adhesive to the screen on the latest models rolling off the assembly line. These new units are already being added to the phone's inventory found at retailers and the manufacturer's retail partners, and will continue to be added throughout the summer.What about those who have already purchased a KEYone prior to the changes that were made? In that case, BlackBerry Mobile says that those older units are under warranty and owners should contact BlackBerry support for a warranty replacement.With a superb physical QWERTY keyboard and tremendous battery life, the KEYone has become the sleeper hit of the first half of 2017. But with the model up against some pretty stiff competition like the Samsung Galaxy S8 and the HTC U11 , BlackBerry Mobile can ill afford to have an issue like this negatively affect the progress it has made with consumers who have been tremendously pleased with the phone.source: @BBMobile
