This has happened to me three times since getting my phone a little over a month ago. The four signal bars at the top go gray and an 'X' appears over the top of them. After this happens, all of my applications force close. The first time this happened, i took my phone to Verizon and they said they have NEVER seen or heard of this happening so they just swapped out my phone for a brand new one. This worked for a day, until the same thing happened. Instead of waiting in line at Verizon for 3 hours again, i called customer service. The lady said it could be from an app (but the ppl at verizon said there is NO way it could be from an app???) So I just decided to do a hard reset on my phone. It has worked for about 2 weeks and now its at it again. Will someone please help me! Its starting to be such a nuisance!!
