KYOCERADuraForce Pro 2 with Dragontrail PRO Display E6921 Black - Unlocked | Rugged 4G Android Smart Phone

The phone functioned as designed, but it didn't work on my cell network which is the only reason I sent it back.

Our old Pro 2 stopped working on WiFi, and after all sorts of troubleshooting by our enterprise network team it was determined there is a fatal issue with the OS. This has been documented online as well, and appears to be a result of an Android update that was pushed by the carrier and appears to be unrecoverable. This brand new one had the exact same issue, so it appears it is an Android problem. Works great for calls, but no WiFi operations, so useless for security patrol/access control app operation.

About ten years ago I went for a walk and got rained on. My T-Mobile branded phone was a brick. They had a hardened phone called the Kyocera Hydro and I switched. I've followed the Kyocera line since and been very happy.As the other reviewer said, the phones are tough. When T-Mobile dropped all the lines of hard phones I stayed with Kyocera, on T-Mobile. I tried three others: a CAT branded phone where the screen broke and the warranty service was terrible, a Nokia 7 that leaked right into the screen (at which time their warranty service was terrible, and I wasn't trying to fix the screen), and a Motorola Moto X. I like the Android One OS on the Nokia, but I guess Google has dropped that.As far as I can tell Kyocera is the only manufacturer of Mil Spec phones outside China. They make Durafore Pro 2 for Verizon (6910) AT&T (6920) and this one for first responders and other industrial specialties. No bloatware that I've noticed. I used a Verizon for six months and it has some intrusive stuff.A successor is coming out, so I guess these 6921s are coming available. I've had it for two months now and I'm happy. check you vendor though- I've bought from cell phone shops on Amazon and gotten 6910s instead of a 6921. No problem with the return, but it was a hassle. This vendor was a packager for proprietary industrial users. I had a couple of e-mails with their marketing, asking some technical questions. Not available today.Update November 2022- 18 months, dropped many times (got thrown down a stairwell once) and I'm still happy.

It's a great phone and great value for the price.If you subscribe to Straight Talk Wireless and all you have in your region is via a Verizon network of towers, DO NOT buy this phone. It is an unlocked GSM (not CDMA) device that Verizon will not allow on their system.Post Script: I'm no longer with Straight Talk. They pushed an update to disable Wi-Fi calling that bricked the phone. Their EULA allows this. You know, the fine print we never read?Now with Verizon.

I really liked this phone but couldn't get it to work because it was locked. Two carriers confirmed this and Amazon couldn't or wouldn't have it unlocked. This is the second cell phone purchased from Amazon that was locked, but I'll assure you it will be my last. Very frustrating!! Caution, just because they say it's unlocked means nothing. Between these 2 cell phone mishaps, I've spent over 7 days running around trying to get them to work. I would warn anyone to beware of buying a used or refurbished cell phone from Amazon.com Services, Inc. that the cell phone may not be unlocked as advertised and they will not go back to where there purchased these phones for resale to have them unlocked.

It does seem to be decently durable so far. However, even on that front, the charging port cover is poorly designed such that the O ring failed and is no longer protecting from water (the whole point of having this overpriced phone). It feels like a cheap phone from 5 or 10 years ago, as very basic apps cause it to freeze up. Worst camera quality I've ever had, and the battery doesn't make it through the day. If this phone cost ~200 it wouldn't be a bad deal, but after spending so much I'm dissapointed

This phone does not work on Verizon network.The phone is solidly built like others in this family.Kyocera got rid of the mechanical navigation buttons at the bottom of the screen by putting them on screen instead. This works well and reduces more options for water and dust to enter the phone.Oddly, the adjustments for brightness and sound are less sensitive than earlier models. The maximum screen brightness and sound volume are less than on earlier models.

Does not work on ATT network
