Weird S4 power button (possibly LCD screen?) issue
About two months ago when I clicked the power button to turn the LCD screen of my S4 on (so when the phone was already on) the screen flickered two green bars at the top of the screen but did not turn on. After pressing the button a few times the LCD screen would actually turn on (so no green bars) and then work perfectly fine. Over the past 2 months this problem has gotten worse. It takes more clicks of the power button to make the phone start functioning, and recently it has required taking the battery out and turning it back on.
I have done a soft reset and it began working well again. However, over time it has worsened again.
A co-worker has indicated that this problem happened to his S3, and that it required replacement of the power button; it was a connection issue between the phone and the power button.
Please let me know if this sounds right and what I should do!!
