I was looking at the Galaxy A20 but I See it has a good Barttery Life because the RES. is Low. But on a 5. Inch Screen will I See a Big Change or will the RES. be Ok? And is the Android Version Very Very Old? I have a Galaxy J7. now and I can get a new one from my Provider. And the Galaxy A20 is one of the ones I can get. I just wanted to know if it will be Ok or if I should Pass on it?
