Huawei has officially launched Android 6.0 Marshmallow for the P8 Lite. The release of the firmware update was announced on the company's Polish fan page.
Weighing at 1.5GB, the software update for the P8 Lite will come first to those with unlocked smartphones as carrier ones will have to wait for the firmware approval and testing.
In any case, the update is already seeding in Germany and Poland, but it should be available in the rest of Europe very soon.
