Reactivation Lock is a feature implemented by Samsung to thwart attempts for an unsolicited factory reset. In case, a factory reset happens from the Android recovery, the device detects and asks for the Samsung account details to proceed. It’s a handy feature if you ask us and if you haven’t activated, you can manually activate it by going to Settings > General > Security.
Some of the other improvements in the new software update include a paintjob for Samsung’s stock keyboard and some fixes like reactivating one-handed windowed mode and direct pen input after starting Pebble’s accessibility service.
