Happened again on update to 7.29.0.15822 (8d88947c).
This was after I updated PMS to 1.18.8.2468 (5d395aa9d) and Android 10 to the February 1, 2020 Google Play system update.
@jesusmc: I exported another set of debugging data and another Android bug report after updating this morning. Would you like me to send those to you, too, or are the previous ones sufficient?
Please send them to me again. Thanks
Happened again on update to 7.29.0.15846 (e55f5d7f).
App logs and bug reports sent to @jesusmc for both 7.29.0.15822 (8d88947c) and 7.29.0.15846 (e55f5d7f) updates.
Would you mind using a custom version of the app adding extra logs? Can prepare it tomorrow.
Thanks in advance
Absolutely. Will you let me know what extra logs I might add? I thought I was already sending you everything I could!
I guess it might be PMS logs?
Sorry, what I meant is if you would mind using a custom apk built (by me) on top of current beta one in which Iāve added some extra logs around the area in which the app handles the device name in upgrades.
Oh, yes, absolutely! I totally got that that was what you were asking about the first time! Sorry I was unclear in my followup response/question. 
Got it; now I understand. I didnāt get at first that you were instrumenting more logging in the custom apk; I thought you might have been asking if I would be willing to test an apk that potentially fixes the issue and to send you additional logs. But now Iām clear!

Plex updated in the middle of the night last night. This morning, I installed the March 5, 2020 Android security update. After restarting, I captured Plexās app logs after noting that the problem recurred.
Now Iām on Android 10 build QQ2A.200305.004.A1, but we donāt have conclusive confirmation that the renaming behavior would manifest on a Plex app installation/update after this security update. But I think we can make a reasonable guess that it probably would.
FWIW, I havenāt received anything by email about the custom version of the app (for the more verbose logging). I can email the app logs that I captured, but Iām not certain they will be particularly diagnostically useful beyond the previous ones I emailed.
Happened again on update to 7.29.1.16015 (d3453229).
Iāve captured both the Plex app logs and another Android bug report, both after a fresh restart and confirming that the problem recurred.
Happened again on update to 7.30.0.16082 (a42c09f8).
Iāve captured both the Plex app logs and another Android bug report, both after a fresh restart and confirming that the problem recurred.
I can confirm this is happening to me as well on Pixel 4 XL.
Plex Android App 7.29.2.16071 (71e4f554).
Happened again on update to 7.30.0.16150 (cf9ef005).
This time, the app updated automatically overnight, so the in-app diagnostic logs I captured werenāt after a fresh restart, if that makes any difference.
Looks like āPixel 4 XLā as a name stuck when upgrading to 7.30.0.16183 (b9eeac67). Could this be a permanent fix!? 
Sorry to bop in here, but I thought Iād mention Iām having a similar problem. My phone is a Sony Xperia X Compact, and the device is now being listed as āCANVAS DOODLE 3ā on my Authorized Devices page.
Interesting, as far as I know we havenāt done anything about that (I came here to say sorry for coming to you so late).
Iāll of course report back on the next update!
Well, bad news:
Happened again on update to 7.30.0.16218 (8007e7af).
I updated immediately after a fresh restart, then took app debug logs and an Android bug report.
Iām pretty sure that I didnāt miss anything on the update to 7.30.0.16183 (b9eeac67), where the āPixel 4 XLā name stuck from the previous renaming. So now Iām super curious what the differences are between these few successive builds!
Iām working on a special v7.30 build with extra logs around that area atm, Iāll share it with you when ready. Thanks in advance
The team has identified the issue (a tricky one) and will work on it soon!
Thanks for your help!
Iām so happy to be able to help, even in this small way. I love Plex so much and am delighted to be able to advance its improvement! Please donāt hesitate to let me know if thereās anything else I can do!
Iāll keep posting here as the app updates, in case that ends up being helpful to other users.
