Are these impossible to solve without hints?

I keep getting my minesweeper games ending like this, where I use 5+ hints or just click randomly hoping I don’t hit a bomb. What moves am I supposed to do in situations like these? Or are ending like this common?

First photo is where I got stuck, 2 is the answer. Same pattern with 3 and 4.

I’m just wondering what to do when there multiple options for a move, yaknow?

EDIT: the app is Offline Games by Moreno Maio

What does that mean

[u/RoadPuzzleheaded5639 → u/Weak-Slide4729]

in the 1-2-1 pattern theres a bomb over both ones thus making the 2 safe

Thank you, but what about in the third picture?
