I go the other way when discussing phones. Samsung seems lackluster, iPhone seems poorly designed, and they're both ridiculously overpriced for what they are.
I use a Kyocera Duraforce PRO. This is one amazingly well built phone, and I have steadily watched the build quality of Kyocera smartphones get better over the past decade, having used the Torque, Brigadier, Duraforce, and now the Duraforce PRO. FWIW, the Torque is still in use today in my car as a spare phone/hotspot as well as for RadarAlive! Pro.
On to the features.
- The Duraforce PRO is a worldphone. It's capable of multiband operation on CDMA, GSM, UMTS, LTE, HSPA, HSPA+, and, well, I'm certain more. I almost never drop data or service at all, and I'm using Sprint with a T-Mobile backup.
- Dedicated hardware button. I use mine for PTT operation, and it can be used for Zello, or pretty much anything you'd like, as it is fully reassignable.
- It is available for all 4 major US carriers. It is offered as a front-line phone currently for AT&T, Verizon, and Sprint, and it can be had new from T-Mobile if you request it. Unlocked versions can also be used on Virgin Mobile, AT&T PrePaid/GO-Phone, Verizon Prepaid, Boost Mobile, and other prepaid carriers. Many of the carriers have cross-roaming agreements in place specifically for these types of phones.
- Customary micro-SD slot for use of such a card up to 256GB.
- Mil Spec 810G compliant and certified.
- Shock-proof, drop-proof, dust proof, and waterproof. When I say waterproof, I'm not kidding. Not waterproof as in "it can stand a little rain", waterproof as in I tested it at a depth of 6 feet in my swimming pool yesterday. Waterproof as in I turned on a youtube video on day 1 and sunk it in a bathtub for 15 minutes, and it works fine. It's fully submersible, is what I'm saying.
- Speaking of that, an actual underwater camera mode that turns off the touchscreen and utilizes buttons to operate the phone.
- Buttons? Other than the dedicated hardware button, it also has a dedicated camera button which can be used to open the camera app, as well as operate the shutter. When in camera mode, the PTT/hardware button becomes a dedicated video button, too.
- Video? Tons of different modes, including a mode that displays speed, G's, distance traveled, and other info, on the screen and on the video itself. I did a test with that yesterday.
- Although the underwater camera mode locks out the touchscreen, the touchscreen will still work when wet or dirty.
- The power button also contains the fingerprint scanner.
- Comes with Android For Work enabled.
- Crystal clear loud audio from dual front speakers.
- Supports PTT apps like Zello, Sprint Direct Connect Now, Sprint Direct Connect Plus, Verizon Push to Talk, AT&T E-PTT, ESChat, Azetti, all Kodiak-based platforms, and many many others.
- 13MP Rear-facing camera, 5MP front-facing camera, and wide-angle mode. Shoots video at 1080p/30fps.
- Android 6 Marshmallow for Sprint, AT&T and T-Mobile models. Android 7 Nougat for Verizon models.
So, really, I'm not even kidding. If you don't get a Kyocera Duraforce PRO, you're cheating yourself.
