This is my third Samsung phone, second with T-mobile, and the e315 is another winner. Like any new phone there is a learning curve, even from handset to handset from the same manufacturer. Overall this phone is just as easy to use as my last 2. 3 Menu display options was a nice new feature over my last one, I didn't like the desktop style menu so I changed it to the bar style.Some have said entering multiple numbers under one enrty has been a problem. I didn't have any trouble. Don't take my word for it, I'm biased. Here's a quick rundown, decide for yourself:From the Phone book menu > 2. New Entry > Chose number type (1. Cell, 2. work, etc) > Location (1. SIM or 2. Phone) > Enter name(same as previous entry of that name) OR select the name from previous entries (either way you get multiple numbers under one name) > enter the new number > Save!And to the review that said you can't have more than three numbers in one phonebook entry, I have 4 under one entry (2 mobile #'s, a work # and a home # under my gf's name). I also added a 5th made up number just to test and it took that one as well. Maybe a new/updated software release to remedy this problem? I don't know, but there's no 3 number per entry max now.The only negative is all these silver/metalic exterior phones scratch easily. My other 2 Samsung phones still work but look like they souldn't because they are so scratched up.The e315 is another great Samsung phone. I'll wrap this review up with three words: simple and efficient
