File a complaint with the FCC, https://consumercomplaints.fcc.gov/hc/en-us/requests/new?ticket_form_id=39744 Let them know that VZW/HTC is constantly sending you defective devices and will not exchange it for another device and that you are afraid that the overheating could cause a fire.
The complaint is against HTC not verizon. Verizon has no control over manufacturer warranty.
VZW isn't an innocent bystander here. They can either influence HTC or they themselves issue a new device or swap out the OP's defective device for another brand.
Why should they?
That's like Comcast swapping out my tv because the signal is horrible.
I'm in the same position, my second phone started acting up after a month of use and now I ordered my 3rd. I feel like no matter whose fault it is that the device is defective Verizon shouldn't be selling defective products. Stop selling the phone and offer an alternative if it's causing so many issues. I love the phone and features so much but the fact that its barely usable is infuriating.
I'm in the same position as everyone else. I'm on my third HTC M8 Windows phone. Verizon charged me $299 for the last return even though 3 Verizon Tier 2 service technicians reviewed pictures of my phone and agree that it does not have physical damage and that the screen is burned [from being hot] under the glass. The last Verizon Tier 2 technician applied for a refund of the damaged phone fee and it was denied. This week I'm cancelling my services (wireless & air card) and moving to AT&T. I do expect Verizon to support the device that I bought directly from the Verizon store. It was still under warranty and has known issues. The customer service hasn't been stellar and they refuse to do the right thing... Either replace at no cost to me or provide me an alternative phone option. I purchased 30 of these phones and 30 air cards for my business. Since I paid cash for all the phones, I don't have a contract restriction. I'm swapping everyone of them to your competitor!
This happened to both my wife and me. It is easy to fix on your own, but takes a while to complete.
Do a system restore (make sure you have a backup in place before doing this). Got to "Settings / System / About / Reset your phone". This procedure worked in both cases. You will want to allocate an hour or two to do this depending on how many apps you have loaded on your phone.
PS: It really doesn't have anything to do with keeping it in your pocket.
