I like to tinker with things, I own. An important part of deciding to buy any given device is that I can tinker with it, take it apart, install whatever hobby OS on it I like, &c. I'v generally been delighted by my Nexus 4 phone, which I've had for perhaps two and a half years and is my favorite smartphone so far!
Recently, though, Google stopped providing android updates for it (well, I think they'll still security patch Lollipop for a while) when Marshmallow, the sixth food-version, came out. I always like to poke at the new things in life, so I started looking around at my options and saw that there was a Cyanogenmod 13 image for my phone. CM goes by their own numbering system, and 13 corresponds to 6 in the official android versions, which is the latest. I had played with Cyanogenmod a few times over the last few years and so I felt pretty comfortable trusting them with my phone.
On top of trying the new version of android, which seems fine, but hasn't really blown me away with anything new, I also tried unlocking my phone's LTE modem. It seems the n4 shipped with an LTE modem which isn't turned on by default because maybe Google never got it properly tested. Some people got it turned on, though, so it's possible to upgrade your data connection considerably! It was like getting a new phone!
Unfortunately, I also had to seek out and install some Google apps. I'm finding Google increasingly irritating, recently, both in their apps and that they called me for an interview, screwed up the scheduling, then the programming language they were interviewing me about, then let me try again in the right language, and finished up by never responding. Mostly, I would seriously suggest the F-Driod repository of FOSS apps, but I need to install the Google Play Store for my banking app, many things I need for work, and I also make heavy use of the Maps app. So, I bit the bullet and installed Google Play using the Open Gapps project.
For a couple weeks, I tolerated the nightmare of continual modal popups from Google Play Services that informed me that it had stopped. Over and over again, it stopped. In the middle of typing words, it stopped and interrupted me. While trying to get directions, it stopped and never figured out where I was. While trying to find emails, it stopped and got confused. It was really annoying, but it tended to happen in terrible, agonizing bursts, so I could still function. I was busy adopting a dog and being an adult human, so I tolerated it.
BUT THAT ENDED TODAY
I finally sat down and got it fixed.
I tried a billion forum posts that suggested combinations of wiping partitions and dances around blood-spattered stone circles, but that wasn't really useful. I know that most of those things are essentially Skinner boxes, and so I try to avoid them, but desperation makes fools of us all.
I had avoided hitting the 'Report' button on the error dialog, because, on the stock android version, this brings up a wall of legal text about how Google is going to pack up as much data as it wants and ship it off to their servers when you submit the bug report (disclaimer: I never read that and have no idea what it really says, I'm just tired of accepting legal agreements). On cyanogenmod, though, the data will be shipped off to a bunch of friendly hackers (in the best sense of the word) who I don't know, but trust to care more about my privacy than Google, for some reason. I didn't submit the report, but being made by hacker-friendly people, the CM report dialog shows the Java backtrace of the problem. This was the most helpful information I'd gotten so far, and it informed me that the problem was
com.google.android.gms missing android.permission.ACCESS_FINE_LOCATION
But I had given Google Play services that permission!
Eventually, I found an issue that seemed to address it on the Open GApps issue tracker, that contained these commands:
pm grant com.google.android.gms android.permission.ACCESS_FINE_LOCATION
pm grant com.google.android.gms android.permission.ACCESS_COARSE_LOCATION
and that was it. No problems, yet.
I hope that this saves someone all the hours it cost me!
