PARIS–I’m having an unusual week of smartphone use: I’m not unlocking my device with my fingerprints and I’m not posting any pictures. That’s because I’m not using the Nexus 5X I’d been carrying around since late 2015.

On my walk home from Metro late Friday after a very long day, night and day of travel back from Shanghai, my Nexus 5X rebooted by itself. That’s become a depressingly common occurrence lately–but this time, my phone wouldn’t get past the initial Google logo.

I spent the next 48 hours reading up on this “bootloop” issue (see, for example, this Reddit thread and this post from a user who spent far more time fighting the problem than I have) and trying to revive the phone. Putting the phone in the fridge or freezer let me boot the device, unlock it and run it long enough to stage some manual backups in two apps, but I got no further. It seemed clear I was facing a hardware failure, not a software issue.

The tech-support call I requested Sunday led to a remarkably quick resolution: After I told the rep that two other troubleshooting options in the Android bootloader hadn’t worked, he said Google would make a one-time exception and replace my out-of-warranty phone with a refurbished 5X for free.

Good! But I needed some kind of mobile device for my trip to the Viva Technology Paris conference. Enter the Nexus 4 that I’d never gotten around to selling, donating or recycling after retiring it a year and a half ago. I dusted it off, charged it up, wedged my 5X’s micro-SIM card inside the frame of an old prepaid SIM (the kind that lets you push a micro-SIM out of a surrounding bracket), popped that into the N4, and began restoring and updating the old phone’s apps.

Five days in, it’s working… more or less. Having to trace an unlock pattern on the screen every time I wake it is a pain, while constant interactions with the phone have also reminded me that part of its touchscreen no longer detects my fingers. The camera is clearly inferior, the lack of storage space bugs me even more than it did three and a half years ago, and the battery life is also pretty bad.

On the other hand, not having LTE doesn’t matter at the moment, since T-Mobile’s free international roaming only allows 2G speeds anyway. And the touchscreen has–so far-refrained from relapses into the digitizer freakouts that marred its last few months of service. So for the basics of Web browsing, text-only tweeting, checking my e-mail, getting Google Maps directions and taking notes in Evernote, my antique Android suffices.

The problem I now have: The refurb Nexus 5X that was supposed to have shipped on Monday and arrived at my home by now hasn’t gone anywhere. I have a query into Google about the status of that; stay tuned for a future post that will relate how soon I was able to set aside my fossil of a phone. I’d just as soon not have to buy a new Pixel phone when that model is due for its own update, but that’s not entirely up to me anymore.
