I have a phone with /e/ nougat, and one with /e/ q. Many important apps don’t work on /e/ q, but they do with /e/ nougat, in my experience. But I can’t find older versions of /e/ for my other phone, the Essential ph1. Is it possible to still find them?
The apps which didn’t work for me on Essential ph1 with /e/ q are: Talkatone, Lyft, Waze, Uber. Additionally, the Apps app crashes when I attempt to download the PWA version of uber or lyft.
Last version of /e/OS Nougat I have for the mata is 20200211. I vaguely remember there may have been a couple of later builds that were giving some people problems with screen offset issues.
Before thinking of going down to Nougat, have you considered trying Pie first?
I installed and ran the four apps you mentioned on Pie. All good. Not fully tested as I don’t use that kind of stuff but no crashes. PWAs also good.
If you need the last Pie build for mata, let me know.
Regarding the latter, I was going to test installing PWAs on my /e/ Nougat device but found the battery drained while I was at work. Doh!
On my Moto potter I recently set up a ROM to be minimal (Simple Mobile Tools suite as the default apps, PWAs for everything else where applicable). I put the Apps store on the ROM (FireHound Nougat) for the PWA feature. It crashes every time I try to install a PWA (recorded log shows why but that’s for another time). No problem with regular apps. Since I’m on non-/e/ I can’t say it’s a problem until I test on my /e/OS Nougat device.
No big deal though as I use Toby Kurien’s WebApps for that stuff anyway.
I have never been on Q so I’m not sure about the downgrade.
The recommended action is to use a matching firmware first. For me, I would probably first test by doing a full wipe including internal storage (or at least the /sdcard/Android/ directory) and flash normally. Test everything to see what does/doesn’t work, especially data/WiFi/Bluetooth.
If Pi/e/ is seriously broken, then would have to start with Pie firmware.
