The Galaxy S5 Prime got rumored again with reports hinting at limited availability, while Samsung decided to take an in-depth look at the Galaxy S5's heart rate sensor. There were also quite a few discounts in effect – Amazon took off up to $100 on Samsung's Galaxy TabPRO and NotePRO tablets, while UK retailers decided to throw in £100 of Google Play credit with the Galaxy TabPRO 8.4. There's no saying if the deals are still active, but hey, no harm done in giving them a try just in case they are, right?
