I am having a problem with severe overheating, this is the second time needing to replace the battery or phone itself because of a dangerous over heating situation and/or non charging ability at all. I'm very disappointed after reaching out to the Kyocera Warranty department. I was told that I would have to send the phone in and wait 6-10 days while the phone was researched and deemed to be within warranty time frame OR other option was to pay $44.50 1-2 day for shipping and $259.00 for phone replacement fee (in the event I didn't return damaged phone) What is truly upsetting is that I've spent 3 days trying to find another Kyocera phone exactly like the one I have, after paying insurance for over a year the insurance company doesn't carry this particular phone, Sprint no longer carries this phone so my only option was to contact the Warranty department. I've had an employee without a phone for 5 days now, and can't wait another 10 days so that leaves me with no choice but to switch phones. I will be contacting the Better Business Bureau and filing a complaint with Consumer Affairs. If you are going to sell products and offer warranties consumers should be able to rely on such warranty if need arises. I found something very suspicious about the people I spoke with in the Warranty Dept. and would no longer recommend Kyocera products to any of my business or marketing colleagues .
