Hi John and welcome to AC

did you manage to resolve this issue? Moving images from your phone to a laptop should be simple, just connect the phone using a USB cable, on the laptop locate the drive, then copy and paste the images that way.
as for your issue, it might be worth while doing a factory reset to freshen the phone up a bit, but it might also be worth while booting your phone in to safe mode. If the issue disappears in safe mode then the issue is being caused by one of the apps you have installed. Try uninstalling some of the most recent apps and seeing if this resolves the issue.
