I haven`t installed MicroG yet. Could this has something to do with the issue?
Don’t know for sure, but my guess is no. Smarter people than me can give you the correct answer.
Just got mine, first boot went fine thanks to instructions.
It’s possible to live without fingerprint scanner if smartphone is unlocked all the time, while you manually lock the phone when needed (it can be quickly locked with double pressing lock button). However, it’s much harder to live without tap to wake from original Jolla phone.
By the way, C2 initially was very laggy on 5.0.0.21, standard apps did not open and rotation didn’t work. However, after I left it for some time it seems to completed processing something, so now all apps are opening, UI is rotating as it should and performance is more or less normal. Still, hope for better performance in future releases (as already discussed here)

The C2 screen has two main h/w characteristics, heavily rounded corners, and a notch for the front camera. I found both of these features annoying as effectively render that part of the screen a useless space.
Any attempt to overcome that feature will either break the sfos ui design, or introduce bugs in apps.
For example the ‘top bar’ of the home screen has become too fat in order to provide enough space under the notch to display the time or any other information that supposed to be at the top middle.

For example the ‘top bar’ of the home screen has become too wide to accommodate enough space under the notch to display the time.
So my idea is to display the time like:
Instead of HH:MM under the Notch, show it like this:
HH NOTCH MM
Maybe someone can do a patch if Jolla doesn’t want to change it
HH:MM is an acceptable format to display time, HH NOTCH MM is not. That notch is the equivalent of having a couple of thousand dead pixels (e.g. 40x50) at the top centre of the screen.

My C2 battery went to 10%, after that very very soon the battery was totally empty. Too soon I think.
The initial aluggishness could be while AppSupport is starting. Takes about 2 minutes on an otherwise idle C2

Anyone having troubles with identifying or detecting Sim cards and network?
Mine detected Sim card and connected to network (3g not 4g) and could make calls and sms. But suddenly it can’t.
It asks for Sim pin on startup, but no network connection and the Sim page is empty in settings.
I had a sort of similar issue when I switched from 4G to 3G. In my case the mobile interface had gone and that caused some other issues like spinning circles etc. Reboot was failing to fix the issue, I took out the sim card restarted the phone, turned it off again put the sim card back and start the phone.

IIRC I had such issues but rarely.
On C2 I have to disable and reenable SIM on every startup otherwise is not detected properly.
Yesterday I lost ability to send SMS after setup first Andy app and some native ones. Frustrating after two weeks pretty satisfying use as a daily driver.
Received my phone three days ago (38% battery).
Charged to 100% before setting up.
Got through first boot, setup and update to 5.0.0.21 without problems.
Because my XPerias and my Volla 22 had high battery drainage (even in standby) when connected to WLAN, I did only install the recommended apps at initial setup (including Android support) and only used phone calls/SMS for the first three days.
No problems experienced yet.
Phone calls/SMS worked fine.
Battery is still at 57% after three days of usage.
Configured mail-account 2 hours ago. Still no significantly higher drainage.
So: Everythings fine until now

Do you have Aurora Store working? In my case I can`t install any app, I get ‘invalid apk error’ all the time.
Has anybody allready gotten back his retuned C2 from Jolla?
I have.
I have installed few apps I used to use only in my android phone and atm they seem to be working. Also few apps I have uninstalled because they didn’t work the way I thought they would.
How long took it before you got it back? And is it working good this time?
Mine have just arrived at Tampere, sent one week ago, yesterday.
Looks like you have to be very patient.
