📸 Camera: Versatile Triple Setup
Rear Camera System:
| Lens | Specs | What It Does |

Image quality analysis:
-
Daylight (5000 lux): Very good performance. The 48MP main camera delivers sharp images with good detail. The ultrawide camera performs "quite well" in the lab
-
Low light (200 lux): Still acceptable; slight resolution drop, but remains usable
-
Night (5 lux): Significant drop in quality. Noise and artifacts become noticeable; fine details are hard to recognize
-
2x digital zoom: Not recommended — quality degrades significantly with soft details and increased noise
Verdict: Great for everyday snapshots, social media, and well-lit scenes. Low-light performance is adequate but not exceptional. Avoid digital zoom when possible .

⚠️ The Trade-offs (Be Honest With Yourself)
-
No ultrawide camera on some versions — Some regions got a 2MP depth sensor instead of the 8MP ultrawide. Check your local variant
-
60Hz refresh rate — Standard for 2021, but feels dated compared to newer 90Hz/120Hz budget phones
-
LCD panel (not AMOLED) — No deep blacks, no always-on display
-
Low-light camera struggles — 5 lux performance drops significantly; fine details get lost
-
No 4K on front camera — Front camera maxes out at 1080p
-
Aging software — Stuck on Android 10 with MIUI 12; no major updates
-
No official water resistance rating — Only P2i nano-coating for splash protection
-
Mediocre color accuracy — Delta E of 3.62 in Standard mode is average
"It’s not flawless: the screen is nothing special and we’re miffed about the removal of the ultrawide camera, but you won’t find anything better at this price." — IT Pro review

📈 Verdict
