It finally recognized the sim card but said that it wasn't from Verizon (true). It still claims no files on sd (sandisk, yes). I took out the Cricket sim and dumped a couple of apps, including Dropbox, which I've never used. Then all hell broke loose. I have no idea why, but the vpn wouldn't work, then came on by itself I guess, and Firefox keeps pulling this "secure connection failed" stuff. It was trying to dissuade me from going to this site, and it won't show the latest postings. I can't get near Memory Zone, and as if that weren't enough, it's now rejecting the charger, which has worked, if slowly. I paid about 7 bucks for it at a convenience store. What the heck is wrong with this thing (S5)?
