The WE R4 MT6737M is a low- to mid-range Android device running Android 8.1, designed for reliable network coverage but targeted at budget-focused users. Common complaints include bootloops after failed updates, system lag, app crashes, weak multitasking due to limited RAM, and IMEI/“no network” errors, sometimes following unsuccessful software modifications.
Official firmware is recommended to fix such issues, remove FRP locks, restore lost IMEI, or fully unbrick the device after a failed flash or soft-brick.
