Stacey says that when she's driving, her Samsung S5 phone starts to overheat, and her battery life has started to get really bad as well. Leo says that using the phone all the time, even while it's plugged in, will cause it to work harder. Phones are higher performing these days, while battery life has been steadily dropping. On top of that, her S5 was one of the worst phones Samsung has ever made.
Stuart wants to know about the Samsung Galaxy Note 7 and why it was taken off the market. Leo says it was taken off the market because of exploding batteries and Samsung is pushing out an update this week that will render any remaining Note 7s useless unless they are plugged in. The Samsung Galaxy S7 is just as good, and the S8 is coming out this Spring. Sadly, the Note brand is so damaged, it's unlikely we'll see another one. But that doesn't mean Samsung won't make another phone with that size screen. They just won't call it a Note. The OnePlus 3T is 5 1/2".
Joseph has an LG Nexus 5. Leo says it was a really good phone. It hasn't been having very good battery life with Marshmallow, but it seems to reboot by itself. Leo says that points to a hardware issue, but it may also be a bad upgrade. He advises doing a complete factory reset. If the problems persist, then it's definitely a hardware issue and it's time to get a new phone.
