Very Happy with A31

I decided to update my mobile phone, and after doing some research on the internet decided to go with the Samsung A31. I chose the A31 mainly because it contains nearly all of the things I wanted in a mobile phone, and was small enough that I can carry it in my pocket. The phone's width and length are just right. Adding a full case for it added a little more widty and weight to it, but nothing that caused any problems. The most important part of it to me was the telephone, and it is much better than the Iphone I had before. The picture quality is good. The only things negative that I can say about the phone is that is does not have slow motion capability, and it is not great in low light. But, those things I can live without. It took awhile for me to get used to the Samsung after using the Apple Iphone for so long, but being able to add an SD card for additional room for all of the pictures I want to take is a gigantic plus for me. I'd say for the money, you just can't beat it. There are a lot of much higher priced phones that can't do a whole lot more than the A31.
