phones, network connections, and debugging

[cellio]

[Update to the update, 2020-12-14 13:15 EST: Lost service again this morning. After much discussion with a T-Mobile rep, I've learned that they are doing work on my tower to upgrade it for 5G, this work will continue for a few weeks, and while they don't think there are general outages despite my reports, "brief interruptions" are possible during this work. Uh...]

[Update 2020-12-13 15:45 EST: Problem went away on its own; see comment below for more info.]

I generally don't keep my phone's WiFi on; even though I could use my home network, I don't tend to run into throttling on the cell network, this frees up some home bandwidth for other things (like my work computer, since March), and I'd rather not have other WiFi networks passively tracking me when I'm out and about (not a consideration since March, but someday again I hope).

On Thursday my phone started dropping the cell connection -- flaky, not outright reporting errors, but almost entirely not working. (In timing that somehow just fits in 2020, it dropped two minutes before an important phone call.) I've switched to WiFi, which seems to demand more battery, but eh, it's a workaround.

This, however, leaves me with the underlying problem: what the heck is going on? I've already power-cycled, reseated the SIM card, reset the network connections (but not messed around in APN), toggled into and out of airplane mode... none of that helped. I even got a new SIM card from T-Mobile (on Friday) and swapped that in; still nothing. Another device on the same network (and plan) gets low bars but gets bars. This feels like a recent degradation, but in the course of debugging this I learned that Dani uses the home WiFi all the time, so I don't have good data from a second device.

I talked with an actual human at T-Mobile (in order to get the new SIM card), who told me that he's not surprised that a phone released in 2016 (I bought in in 2017) is having problems on "modern networks" (by which we mean the 4G LTE that's been there for the life of this phone). His take is that technology moves on and my phone's antenna probably isn't powerful enough any more. I don't know how to test that hypothesis; if the antenna were completely gone it wouldn't work with WiFi either, but it does.

Is there some other debugging I can do, or any simple repair I can make? Or am I in "buy a new phone" territory?

A new phone wouldn't necessarily be the worst thing; mine is stuck at Android 7.1.1 (because of US trade blocks against China that happened mere weeks after I bought the phone). But the phone otherwise works fine, so if it's fixable then replacing it would be a waste. And, more significantly: WTF is with phone sizes and aspect ratios these days? My phone has a 16:9 aspect ratio and is 6" long. This is a good size for me. Anything bigger won't comfortably fit in my pocket; much smaller and I'll have trouble seeing. And that's where the width comes in: modern phones are too freaking skinny for text! They've all been designed around the idea that you'll watch widescreen movies on your phone, I guess, which I consider ridiculous -- I'll watch movies on my TV or at least my full-size monitor, or if really pressed, my 10" tablet. Not my phone. But to make them support that, they've made the portrait orientation tall and skinny, and that does not work for me.

Remember when cell phones were new and not yet smart? (Some of you might not.) There were two basic styles: flip-phones and candy bars. I never understood why anybody liked the candy bars; they were large and prone to butt-dialing. A flip-phone fit in my pocket fine and its keys couldn't accidentally be pressed while closed. While locking has presumably cut down on butt-dialing, I still don't want the candy-bar form factor.

(My phone is a ZTE Axon 7. I would like as close to its aspect ratio and size as I can get, if I have to get a new one.)

A tip led me to Network Cell Info Lite, which has gauges with needles that hover between the orange and red zones (not completely static). I'll collect some more data points when getting take-out tomorrow.

I've been waiting for foldable phones since learning a bit about OLEDs back about 15 years ago. Of course, I've never been affluent enough to do the early-adopter thing.

I know a couple of guys who work for defense contractors and who cling to their flip phones as a result. I think the 3G networks are still up and running for people like them.

I don't do the early-adopter thing either. I can wait for other people to spend gobs of money working out the kinks. :-)

If the defense contractors primarily need phone contact, flip phones still make sense -- they wouldn't have to turn those over at the door every day when arriving at work the way they usually do with smartphones.
