GSMarena POCO M3 review:
"The default 12MP photos from the main camera are superb for this class, especially when shot in such challenging weather conditions."
"High-resolution 48MP mode is available - but there is no point using it. The 48MP photos are upscaled from 12MP and don't look good."
1 + 2 => no need for 48MP mode in Ubuntu Touch so this thread can be marked as solved. 🙂
