The Cubot P20 is a 2018 value big-screen Android, launched with a 6.18″ FHD+ notch display (2246×1080 px), and powered by the octa-core MT6750T/Mediatek chipset. It features 4GB RAM, 64GB internal storage (128GB microSD support), a 4000mAh battery for all-day use, dual rear cameras (20MP+2MP, bokeh), and a 13MP selfie sensor. The phone supports 4G LTE (bands 1/3/7/8/20), dual nano-SIM, and fingerprint unlock. Android 8.0 out of the box means a smooth UI, but Cubot rarely pushed true 8.1/9.0 updates for this device.
Owners and reviewers love the display and battery, but commonly report: slow fingerprint unlock, random shutdowns, freezing while charging, battery not exceeding 80–90% charge, camera focus lag (especially indoors), ghost touch near display edges, and rare bootloops or dead screen after heavy app updates. Flashing the tailored P20 scatter firmware resolves performance bugs, boot and battery failures, and resets hardware limits to stable defaults.
Critical Notice: Before You Proceed
Flashing Cubot P20 firmware erases all data, apps, and IMEI. Backup contacts, social accounts, IMEI, and SD/Google data before you start! Only use MT6750T scatter files—Cubot X-series or Note-series ROMs will break SIM, display, and camera functions.

Cubot P20: Most-Reported Real Bugs & Owner Solutions
1. Fingerprint Sensor Slow or Unreliable
Scanner may lag or miss—try fresh finger enroll, keep sensor clean. If still bad, latest ROM resets hardware driver.
2. Charging Stops at 80–90% or Shuts Down Randomly
Try alternate cable/adapter, clean USB port. Full discharge/recharge and fresh firmware often restores battery readout.
3. Camera Focus Slow, Blurry Indoors
Main cam can lag in poor light. Use tap-to-focus and keep >2GB free space; factory ROM updates camera module.
4. Ghost Touch or Dead Screen Zones
Notch display sometimes misses edge taps—avoid thick protectors. Reset digitizer with scatter ROM for worst cases.
5. Bootloop/Bricking after App/System Update
Use official scatter ROM to revive; force boot with Power+VolUp (15s) after flashing.
6. SIM/Cellular or Bluetooth Drops
SIM dropout—try reseat, alternate SIM slot, and reset APN/network. Bluetooth lag fixed by fresh flash/driver update.
7. Storage or App Lag Over Time
Keep <40% free memory; uninstall unused apps, use SD card for multimedia. Factory reset/ROM flash if lag persists.
