I used four LTE devices at once in a 100% complete market. The EVO's LTE connectivity issues are real and magnified when used side by side with other LTE devices. And perhaps even magnified further by three other LTE devices side by side at the same exact time.
When you get trounced by an LG Viper, an LG Viper for crying out loud, with LTE Connectivity performance, you get a little more than frustrated. I think that when you only have an EVO running on LTE, you just don't notice it. Ignorance is bliss. The thing that frustrates me is that HTC has not been able to solve this problem. Not only does it frustrate me, it actually nearly scares me.
I own an EVO LTE. I want HTC to solve the problem. But three OTA's has not solved the problem. Whereas, the first OTA solved the threshold issues with all the other devices. This is more than a threshold issue.
Back on April 24th, I warned everyone that there were problems with LTE Connectivity that the EVO was having in lab testing. It was described in lab reports as, "LTE device connectivity in lab testing continues to be problematic due to under defined processes and complications around provisioning and SIM UICC profiles. Escalation of this issue is in progress."
This is more than just a threshold setting. Otherwise, it would have been fixed with the other LTE devices. I'm not certain what the italicized content above means. But we know LTE Connectivity issues existed since lab testing and continue to this day. And HTC is the culprit, not the network. That much we know.
Since I did testing in fully deployed areas in an FIT, I can tell you having a fully dense network did not solve the problem. In fact, it made it more frustrating. Because you were being bathed in LTE and the other devices were going strong, staying connected when you drove through an underpass, or turned behind a big brick building. And the EVO would revert to the 3G. And you would have to cycle through airplane mode again to get back to 4G. And sometimes it didn't go back the first try. Even though the other devices were at -108dBm.
If I didn't have the other devices, or if I was in an area that wasn't fully deployed, I would just assume it was the network not being completely ready, and I just drove out of range of a live LTE site. This is a real problem for us EVO Owners, and we need to make it HTC's problem. Not ours.
