In terms of sound facilities, Redmi Note 9T will not disappoint. It offers stereo speakers with good volume and quite rich sound (for smartphone speakers). It works well when watching series on Netflix or listening to podcasts, you can also listen to music with them - although here it is better to use the universal headphone jack and connect your favorite headphones. There is also a proprietary player and FM radio with the possibility of recording broadcasts to MP3 format.
Photos and video
The main camera has 48 megapixels, phase detection autofocus and a lens with a brightness of f/1.79. It is accompanied by two additional modules of lackluster usefulness - a 2-megapixel macro camera and a 2-mgapixel depth measurement camera. Therefore, let us ignore them and focus on what is really important. The main camera has a high resolution, but uses (like most cameras with 48-, 64- or 108-megapixel cameras) pixel stitching technology to achieve a better, brighter photo. Here, by default, photos with a resolution of 12 MP will be taken, but you can choose a mode that will allow you to use the full power of the matrix. With the help of the main camera, you can record video in a maximum quality of 4K 30 fps.
What is the quality of the photos, considering that photography is not a priority in this model? In a word - good. Both in daylight, in artificial light, and at night (but it's better not to look too closely at the details). In places the photos seem too processed, especially when HDR is activated. The colours are sometimes too pale, and sometimes too saturated - in general, the camera's work is quite uneven, but the simplest graphics editor or Instagram filter will help with this type of imperfection. Here are the shooting results:
The camera in Redmi Note 9T 5G offers decent photos in its price shelf - they look satisfactory when taken in daylight, there are also no worst photos after sunset and with artificial light. However, I do not understand the manufacturer's decision to deprive this device of a camera with an ultra-wide angle lens. I suspect that any user would rather snap shots using a wide angle than have a questionable macro camera and a completely unnecessary depth detection camera.
The camera application provides a number of modes related to photos and video recording, including night mode, Pro mode, panorama, slow motion and time-lapse mode.
At the front there is a 13 MP camera with f/2.25 brightness, which can record in the maximum FullHD resolution. It gives photos that are correct, sharp enough, with natural colours, with correctly applied blur - I have no comments.
