Same issue!
I bought my lg g2x from tmobile on the 22nd. At first I had no issues whatsoever, the phone ran great and I was very happy with it. A couple hours after I got it, I noticed that sometimes when I would unlock the phone, the screen would just be blank for 10 seconds before it came on. I also have had issues with bad connection to the network, choppy calls, and dropped calls. Yesterday, I was talking with my girlfriend over the phone when the phone just randomly shut itself off. It COMPLETELY turned off and would not turn back on. I tried holding the power button, I tried pressing it lightly, nothing worked.
Solution:
I removed the battery from the back, waited10 seconds, put it back in, and BAM the phone turned right on.
What I am going to do:
I am definitely going into T mobile to get a NEW replacement. Dont let t mobile do that whole "we will get it fixed" bull****. Tell them you have had this issue multiple times and you need a NEW phone. To bad they are closed today or they would be replacing mine. Gonna have to wait till tomorrow though
