Quick question. My wife and I each have had our S4's for a few years. Just recently we have had some storage problems when it comes to updates and so forth. We have moved as many apps as we could to the sd card, deleted apps to do updates and so forth. Even used a cache cleaner to do updates. But today I sent my wife an email and she said it showed she does not have enough storage to display it. We both use Yahoo by the way. She went ahead and deleted our current text message thread between the two of us (which we both did a few weeks back) and instantly she received 14 new emails. Is this normal? Is there a way I can set her up so that yahoo uses her sd card instead if this is normal? Thanks for any help!
