I bought my galaxy s5 three months back and i was happy with it. Until the time i tried to delete contacts off of my phone. I looked for a delete function on the phone, but failed to find any. I looked online and many video tutorials had a function to delete contacts in the app, but i couldn't find any. Their layout looked like this: While mine looked like this: That wasn't my only problem. I realized that my s5 version was in kitkat 4.4.2 and lollipop was already out. I tried to update my system, but it said my system was up to date. I tried kies to update, but kies wouldn't detect my system. There were many other problems, like missing some of the settings and functions that a s5 should normally have, not being able to change my lockscreen without an app, and so on. I really want to solve this, thanks.
