I still have the A70 and use it daily. It still works well albeit battery is showing ageing, which is fine considering how long I've had it. Trying to chose a Samsung phone other than the S series is such an awful mess. There is no coherency, wether it's SoC specs or screen size, they're all over the place. They really need to do better.
In 2019, Samsung consolidated its budget and mid-range product lines by merging them. However, the company has since introduced new Galaxy smartphone lines, reversing the simplification.
