Why does the old pictures we took using our old mobile phones looked kinda blurred when we view them now but looked pretty clear at the time we took it?

You’ve got used to higher resolution photos now, so looking at older stuff, you notice the blurriness.
When you have an old phone, and look at someone else’s phone, if it is higher resolution, you notice the sharpness at the time.
Old digital pictures with old cameras were viewed on old (lower resolution) screens.
On the higher resolution screens we use today, low res photos look blurry.

Because all the photos back then looked like that. All the cameras on phones back then were crap, but the screens were crap as well, so you couldn’t really tell by comparison.
Now that screens and phone cameras have gotten soon much better you can easily tell by comparison.
Resolution mismatch. The same concept of watching old SD television programming or DVDs on modern 4k TVs.
The higher resolution displays show more detail – good and bad. In the case of low res content, it amplifies the lack of clarity and imperfections.

When you take a picture using a phone camera or normal digital camera, the image snapped is made up of millions of little squares called pixels.
As technology advances on mobile cameras, it can fit more pixels in the image (i.e, the MP of the camera). Pixels make the ‘shapes’ in the image, so with horizonal and vertical lines, pixel density isn’t too important. It is important on diagonal lines though as it creates smoothness of the image to our eye.
If you had 10 squares diagonally into a set space, it would be apparent and jagged, whereas if you make those squares smaller, say to fit 100 squares rather than 10, the diagonal will appear smoother.
Then there is the viewing device. A better resolution (i.e., how many squares on the screen) can display an image with better clarification.
If you view an image of a lesser resolution on a higher resolution screen, in order to fit it on there, it attempts to ‘fill the gaps’.
For example, if it were a 1:1 ratio, it would be 1 pixel to 1 pixel. If that ratio is changed, say 2:1, then the screen needs to use 2 pixels for 1 pixel in the image, undoing some of that smoothness on the diagonal lines.
Try zooming into one of those grainy images next time and you can likely see the diagonal squares.
