I'm pretty smart when it comes to using Smartphones, and I've had a few friends and family members complain to me about their yahoo emails and how they are always being signed out of it. And sometimes they can't even log back into it on the default app. Sometimes I recommend that they just change their password and that does the trick. So my question is..Does everyone come across these issues with Yahoo? I'm thinking it's more of a yahoo email service issue than it is with smartphones.
