Hello, a few days ago I bought a new Samsung Galaxy S4, and I immediately discovered two major issues. Issue 1: It will not send or receive texts. Every time I try to send a text it looks and acts like it sent, but the person I texted does not receive it. Issue number 2: When I try to watch a video on YouTube the videa has about a dozen horizontal bars on it with each bar playing a separate section of the video. It is temporarily fixed if i change the resolution of the video but this only lasts at most 5 minutes. I have checked all the settings, tried a soft and hard reset, cleared the cache, everything I could think of. I really like this phone but if I can't get these issues resolved I'm going to return it. I am running Android version 4.2.2. If there's anything you could tell me it would be very much appreciated. Thanks in advance!
