I've owned this note 3 for maybe 2 months. I noticed in the first few weeks of owning it that it was very slow at times and would not work properly. Text messages wouldn't send and apps wouldn't install after downloading . After a lot of wondering I discovered that my issue is when I'm connected to any wifi. My alarm would not work and my lock screen wouldn't work with music apps and more. I have no idea how to fix or trouble shoot this. I know its because of wifi. I've tried 4 different wifi locations and it's the same issues. The Internet browsing and apps work fine off wifi, it's the phone that starts to act up. Any ideas? I've already reset my phone plenty of times.
