I was watching a movie on my Samsung Galaxy S5 the other day when suddenly my phone screen went black. I tried to turn it back on, but of course that didn't work. After closer inspection I noticed that the phone was actually still powered on and functional, as the LED lights at the bottom of the phone were still lit up, and vibrated upon use. I was still able to hear noise coming from my phone, and felt it vibrate when I touched certain parts of the screen, indicating that I was actually performing actions. Considering the fact that I am not able to navigate my device considering the lack of display, the only way to power it off is by taking out the battery, then powering it on again. Once again, I'm greeted with the AT&T boot up sound effect, but the only thing that happens to the screen is a quick white flicker upon turning it on. I don't want to have to buy another phone, but the simple fixes that I've attempted have failed to work. For example, taking the battery out and holding the power button for 2 minutes, then leaving the phone alone for 10 minutes. I find this to be completely absurd considering the fact that I literally did not do anything to negatively affect the phone, and it just kicked the bucket on me. I'm currently without phone service, so I haven't been able to contact any Android Tech Support numbers in the past few days. Is it worth trying to do so to see if they could possibly replace the phone considering their hardware was faulty? If not, are there any other known fixes to this issue? Should I take it to an AT&T store or a phone repair store? I'm simply looking for my best option here. Thanks.
