I bought a Galaxy S6 2 weeks ago and the screen suddenly becomes unresponsive. In order to swipe down from the top to bring up the settings menu I usually have to touch it 3 or 4 times for it to respond. Texting is hit or miss, as it rarely responds to the letters that I'm trying to touch. I've rebooted, started in safe mode, and it still has the same unresponsive issues. Anyone else with this problem? Very, very frustrating to have a new phone act like this.
