I'll watch it a few more days. It's under 1 year warranty, so I've got 10 months to take it back if I need to.
Thanks everyone, this was a lot of help!
Exactly like Marc is saying, just guesses here:
Best guess: One of the other Sage Android Forums staff members, EarlyMon, highly recommends contacting higher level Sprint tech support over the phone and scheduling an 'RF Box Test' at a local corporate store to help test and diagnose your self-proposed hardware problem or radio deficiencies. I think this is a situation where you might benefit from this test or being able to speak with the tech that does the test for you in regard to the symptoms. I'm assuming that they can run a test on the 4G connection and will be able to tell you if it is not performing up to snuff.
Not so good guess:
You could look in your settings and see if the Sprint One has a readout of your active data connection. It should be in 'Settings -> About -> Network' or a similar path (could be moved/removed on the One) There are also applications in the 'Play' market that can help show this data to you (OpenSignal is one).
3G should show some details like these:
Signal Strength: -92dBm
Mobile Network Type: CDMA -EvDo Rev. A
Service State: In Service
4G will appear something like this:
Signal Strength: RSRP(dBm): -117 RSRQ(dB): -12
Mobile Network Type: LTE
Service State: In Service
Then go to a Sprint Store and compare Your One connected to LTE next to the One floor display. They should show approximately the same dBm readouts. These read outs are archaic, inaccurate at best, and are HIGHLY subjective. However, at least this way you are comparing apples to apples and have a baseline.
Sprint stores are equipped with a 4G signal repeater, which is why you are getting such a strong signal near there. It may be too
strong for a good compare of signal loss over distance and how your phone handles it, but it may give you slight confirmation if your One is achieving a significantly
different connection than the floor display at optimal conditions.
Another not so good guess:
If you called Sprint and they thought your 4G settings were not quite configured right on your phone, you could try using Sprint.com to de-activate and then re-activate your One (activate an old device on your phone line then re-activate the One on your phone line). Back up your phone first.
Maybe putting your phone through the hands free activation process and fully re-provisioning your data profiles and account info will help it to re-configure?
of the data connection is not always
an accurate way to assess the signal strength
or the quality
of the connection.
The manufacturer's 1-year warranty is provided and serviced by the manufacturer HTC themselves and not Sprint (in most cases). This was a Sprint policy change a few years ago - could have change by now too, I don't know.
You can try taking it to a corporate Sprint store for your 1 year warranty claim, but usually they will offer to replace/refurbish the device in the store tech lab at your cost and forgo the HTC warranty claim process (unless you have the Sprint offered insurance). If not and you want to make a claim with HTC, Sprint sometimes help get you started with HTC contact info, but then HTC handles it from there. You ship your device to HTC and are left with no phone for an extended period of time until they can log your RMA - or you can activate your old Sprint phone that you have sitting around.
Sprint insurance if you have it is generally handled in store but administered by Asurion LLC. Sometimes claims/cases have to go directly through Asurion and not Sprint at all.
can help you examine your local area with Sprint LTE as mapped by other users of the service. Like OpenSignal it helps provide a more accurate representation of the signal-area as reported by the active user base
