This used to happen to my with my HTC Thunderbolt and was the primary reason I upgraded to the S4 because the Thunderbolt became unusable and I was constantly pulling the battery out to reset. I just assumed the problem with the Thunderbolt was a function of the Thunderbolt being a first generation LTE phone and insufficient network capacity on the part of Verzion. Now that it is happening with my M8 but not with other phones at the same time and place, it appears that something is wrong with how HTC phones talk to the Verizon network. As I recall, this was a known problem with the Thunderbolt.
I notice it mostly at work, where I use the web the most, and sometimes at home. At work, there are a lot of offices nearby and thus a lot of cell traffic. At home, my phone sometimes switches between 4G and 3G. Thus, both areas are subject to high traffic or weak signals. I haven't used the phone elsewhere enough to know if it happens is "normal" traffic areas.
What it looks like to me is that when I am in places where there is heavy traffic or a weaker signal, the HTC doesn't handle communication with the cell towers properly. It is like the phone either can't find the network or, more likely, it finds the network and then loses communication and traffic is juggled. Maybe the signal put out by the HTC is not strong enough or there is something wrong with its receiving circuitry???

I have bluetooth, wifi, airplane mode, and location off, and only a couple of apps.
I really like this phone (the M8). However, I lived through this problem for 2 years with the Thunderbolt and then did not have the problem for the past year on the S4, and I am not about to deal with it again. I am finding it hard not to conclude that I just need to return the phone.
I thought I would ask whether anyone has experienced this problem or has any idea about whether it is fixable as opposed to just a fundamental problem with HTC phones.
Thank you for taking the time to read this.
