Before I got the S5, I started off with the S4. Was really happy switching to Android after owning the iPhone 4S for 3 years. I pretty much got tired of it, even when it was Jailbroken. After I saw the S4, I jumped on it.
Took me a week to get used to the S4. Finally got used to it and rooted the phone. After the 4.4.2 update was released, it started acting up. SIM card was unable to read and after a couple of restarts, it would work again. Then one day, the phone stopped reading the card and was unable to get it working again. I thought I needed a new card, so I had it replaced for free since it also wasn't working. The same night, I went to a drive in, and wanted to check the time on my phone, then find out the screen cracked :/.
So I went back to the AT&T store and picked up the S5. I love how fast the phone is and battery life is unbelievable. I even have it rooted thanks to the person that made it really simple to do. Hopefully one day I can do something productive and help around here. Till then, have a great weekend and a Happy 4th of July.
