so i have the galaxy s two phone. i know that the whatever number version is about to come out within six months that can read your mind and tell you when youre supposed to think about what you are thinking about, but this is about my phone: the samsung galaxy s two that came out . . . two to three years ago? well anyway, it does the strangest thing, and others around me say that theirs does it too. i deleted my old email off my phone after a job transfer switcharoo, and set up my new account. gmail based. set up fine with correct port numbers and all that. i get my emails, but if i open them and then close the email app, the next time i open my email, the emails ive opend are gone off my phone, not my account, just my phone. i f i dont open the email, it stays there. never had that happen. tried every setting, every change that should be telling me that no emails will be deletec unless i delete them, but it does what it wants. plus the wireless comes on whenever it wants, and it does do that restart and shut off then reboot itself back, for no reason, but that is rare. ive been told just replace your battery. is it that simple? thank you tech gigolos.
