Since the official release of Android 5.0, major manufacturers have announced their own product upgrade schedules. Motorola was the first to take "practical action". Moto X (2014) has already pushed Android 5.0. Of course, Motorola's system is very close to native. Later, LG also announced that it would update Android 5.0 for G3 in the near future.
The G3 will first push the new system upgrade in Poland. In fact, the Korean version of F400S G3 has leaked Android 5.0 firmware download. For ordinary users, it is recommended to wait for the official push of the upgrade.
