I have a few major issues with my galaxy S3 and I'm wondering if they have been addressed in the S4. I think I'd actually buy the S4 outright if they were improved quite a bit. I can't seem to find out if they just moved the location of the speaker or replaced it with a better one. 1) The speaker on my S3 sucks. I can barely hear people on speaker phone unless I'm in a totally quiet area. When trying to show people youtube clips with any background noise people have to get right up next to the phone. 2) I basically can't see the screen if I'm outside and the sun is out.
