I upgraded to an S6 when my S4 failed. I hate it. Hate hate hate it.
The software guys spent some much effort “improving” it that the basic functionality i liked about the S4 are gone.
The S7 and successors have a huge hole to climb out of.
Yes. I have S3. Hate everything over a 5. They changed the 6 up and the note. Awful.
Better with a 5 if you can find one.
