The Cubot P50 is a 2022-stock, Android 11 smartphone targeting affordable owners needing NFC, secure RAM, and a Sony main camera. It ships with a 6.22″ HD+ display (720×1520 px), Helio P22 (MT6765) octa-core, 6GB RAM, 128GB storage (microSD up to 256GB), and a 4200 mAh battery. The triple rear camera (12MP Sony IMX486 + 5MP macro + 0.3MP depth) and 20MP AI selfie lens are supported by Face Unlock and Google Assistant on a clean Android UI. Dual nano SIM 4G, NFC, Type-C, and a 3.5mm jack target mainstream users in many markets.
Owners report unique issues: display not bright enough for sun, camera focus slow, “ghost tap” glitches, fast battery drop in temperature swings, sluggish LTE or data, and rare bootloops after caching errors or system updates. Cubot’s support response is often slow, so using the correct full P50 firmware fixes the majority of bricking, charging, and connectivity bugs.

Cubot P50: Real Bugs, Complaints & Solutions
1. Display Not Bright Enough Outdoors / Ghost Taps
Several owners mention screen is hard to see in sunlight and sometimes registers phantom inputs. Use max brightness, avoid third-party screen protectors. Latest firmware improves accidental touch handling.
2. Battery Drops Fast in Hot/Cold, Charging Stalls
Temperature swings and background apps drain battery fast. Try “Ultra saving” mode, recalibrate post-flash, and clean USB port. Stock charger recommended.
3. Camera Focus Slow / Not Sharp
Sony sensor is fair, but autofocus can lag—use tap to focus, AI mode. Fresh ROM (V08) fights driver bugs that caused focus problems.
4. LTE/Data Slow, SIM Not Detected
Some users get poor LTE throughput or SIM errors. Reflash, check APN settings, and swap SIM slot for better performance; only use MT6765 builds.
5. Bootloop/Black Screen after Update
Rare, but fixed by flashing latest stock ROM, then removing battery (if possible) and holding Power+VolUp 15s to force boot.
6. Cubot Customer Support Slow
Brand support slow to respond—official ROMs and community fixes resolve most issues faster than warranty repair.
