Review: Samsung Galaxy S III

I have had the HTC Evo 4G (forget about the big deal 4G WiMax)...Never Ever could get it to work.

Anyway, I am continually encountering a "low memory" warning and when I do I lose functionality most notably my email won't send or receive. When I go to my Application Manager I see that there I lose my capability at about 43MB (Free). I assumed this was a RAM measurement but it isn't. I have plenty of free RAM. So this is phone memory, but I don't know how to measure what I Have. Right now it says 371 MB used and 57 MB Free. This is a total of 428 MB Memory. What...???? I though I had gigabites of internal memory.

My question is what is different on the Samsung G3 in this manner. Is this improved by going form 16GB to 32GB in selection decision or is there a way to partition this memory differently. What is the "effective" memory I will have on the SG3 compared to the HTC Evo ????

I am not an expert and hope I haven't scrambled my question beyond recognition. I just don't want to invest in a new phone with the same issues.. B-T-W I really don't have an inordinate amount of downloaded software on my phone. I keep thinking that the Bloat Ware is using up most of my User Memory for Applications.
