Hi All. I have a question regarding which phone/OS works the best with Uber and Lyft. Currently, I'm on an old Samsung Galaxy S4 which likes to overheat and is known to be slowwwww. Other than those 2 things, I haven't had many problems. I want to upgrade, but am unsure which route to go. Which do you recommend? Sticking with Samsung and moving up to 6/7? Or dumping it to go with an iPhone...probably a 6/7 as well. I'm looking for what you think and any problems you've had using the apps if you use that phone to operate them. Thanks!
