I have an HTC EVO 4G LTE phone in Atlanta and briefly got a signal back during the initial roll-out, then nothing. I have used sensorly, opensignal, and other apps to try and detect LTE but nothing. I finally called Sprint to complain and the representative informed me that there were no reported problems with my model phone that she had the same phone in Dallas and had no problems at all getting LTE on her device. I took my phone to the Sprint repair center in Roswell, GA where the tech rep's are just great. They checked out my phone and indicated they saw no problems with the phone and by using the MSL code could connect to LTE there in the store. However, they were unable to reproduce it working for me in the store. The tech rep. told me there was a known problem with the threshold on the HTC EVO 4G LTE, but I don't know where he got that information. He also said you had to be VERY close to the tower to get the phone to switch to LET. I also saw a Samsung Galaxy S3 in the store that was showing an LTE signal. The phone rep. called me back and told me that there actually had been an LTE problem in Atlanta that had gone unreported, but that it was now fixed, but I was still unable to get any LTE signal without using the MSL to switch to LTE only mode. I have a co-worked with the same phone. He indicated he has been able to pick up an LTE signal. We compared all of our version numbers - HW, Software, every number you can compare on the phone. His were all absolutely identical to mine. This would tend to indicate to me that perhaps this is not a threshold issue unless phones with the same HW rev numbers (003) and SW versions would end up with different thresholds. Other difference is that my phone is in an Otterbox, his only has a screen protector. I have also been told that it's only a "handfull" of the HTC EVO 4G LTE customers that have seen this problem and that has been repeated on the Sprint forums. I am starting to wonder if there is/was a quality control problem with the phones. Either a marginal antenna chip, marginal connections to antenna (cold solder joints, etc...) that could be at the root of this and without some pretty serious diagnostic equipment to hook up the phone to, it will be very hard to determine what is causing this problem. Does anyone know how to translate a HTC EVO 4G LTE serial number into a build date? HT25DS......
