I have a Nexus 4 that I purchased on release with ST and it works great. However, I advised a friend to purchase the same about 3 weeks ago and she has 0 bars when I have 4. Straight Talk is giving her a rash of crap saying it is Google's fault. Has anyone had this problem previously? I had her put all the same settings I have and nothing seems to work. At this point I am wondering if it is a hardware malfunction. I would appreciate input from others if this is perhaps a problem with the latest batch of N4's. Thanks in advance.
