I am a former iPhone user and still use my iPad for work. I switched to the Galaxy S4 and love it. One problem though. Everyone who used to text me through iMessage sends me texts that I never receive. I turn the iMessage off on my iPad since I only use it 2 or 3 days a week for work. The iPhone users still get my texts, but I don't get the majority of theirs. The weird part is, sometimes I do. Any ideas?
