Group messaging on Samsung Galaxy S5

[deebeen21]

I currently have a Samsung GS3 that I've had for the last two years. I understand that with all of the newer models out today some of my issues with the GS3 have probably been fixed. However, one of the biggest issues that may lead me to switch from android to iPhone is group messaging. With my GS3 group messaging works where I am able to send and receive messages, but the device lags and freezes when I receive an influx of messages from my android and iPhone using friends. All of my friends with androids have this issue, including two who have the GS4. Just wondering if anyone can give me an honest response to any issues they've heard of or found with group messaging on the GS5. Thanks!
