Back in February, a security vulnerability was discovered in Windows 10 Mobile that leaves your photos exposed to anyone that picks up your phone. With the device locked, all you have to do is take a picture, delete it, press back, tap the thumbnail of the image, press back again, tap the thumbnail again, and then press back and tap the thumbnail one more time. With that simple process, you get access to the owner's full camera roll.
Today is Patch Tuesday, and just as we reported with last month's updates, the issue still hasn't been fixed in build 14393.1066. Since this vulnerability was discovered, we haven't been able to replicate it in preview builds of the Creators Update, which will begin rolling out to phones on April 25.
Unfortunately, recent reports indicate that the Creators Update won't be rolling out to all Windows phones that were supported for the Anniversary Update (AU). Because of this, it seems likely at this point that many devices might never receive a fix at all.
The last time that a large number of handsets were supported by the Insider Preview but not the official update was in March, 2016, when Windows 10 Mobile started rolling out to older devices. Phones were able to continue receiving updates for version 1511, but after the Anniversary Update was released, there were only a handful more updates.
If this is an issue that concerns you, you can always grab the Creators Update via the Windows Insider Program, as it's available through the Slow and Fast rings. For now, all of the devices supported for the AU can use that method.
