Feedback on Jolla C2

#774

I guess this is not to talk about SailfishOS.
Mail app can’t retrieve emails since Saturday. Is it C2 issues ? I can send emails but no new emails received.
Also Microtube often stops as ‘buffer dropped’ error. Is it becaude memory of C2 is too little ?
Also C2 does not recognise USB-C headphone, BT headphone keeps connected but suddenly sounds come from speaker instead of the headphone.

Any C2 users also face those issues ?

C2 Feedback:

  1. In germany it connects and makes calls and sends sms on sim1 or sim2 4G, cannot send/receive MMS though (telecom, reception for mobile network is much better than Librem 5, wifi seems a little slow to connect)
  2. in the US you can send SMS messages but mobile data connection mostly crashes, sim disappears, it shows 2.5G as network indicator, you have to restart it 2-4 times, turn on airplane mode, turn it off after restart wait etc… only works sporadically
  3. boot is surprisingly slow, my Librem 5 with byzantium boots faster with full disk encryption
  4. camera is great and works fast, though when taking pictures into direct sunlight colours are a bit washed out and images are overexposed and have a blue tinge (you will have to play with the white balance settings to make it look good)
  5. the sailfish os UI and touch interactions are intuitive, fluid, and flawless
  6. apps are great, and except puremaps haven’t experienced too many app crashes!
  7. GPS appears slow to get a lock, i don’t think it is using any AGPS, also GPS uses online mozilla service which doesn’t exist anymore, so that probably needs to be fixed, instead use AGPS
  8. Aliendalvik and Android integration is leaving something to be desired, at first it worked and I could browse the web using duckduck go android app, but then suddenly no more internet connectivity is detected, works with WIFI does not work with mobile data (known bug), apps like soundcloud do not stream any music with message “SoundCloud won’t run without Google Play services, which are not supported by your device”
  9. Jolla should really have a default disks app so you can claim ownership of a SD inserted from another phone, format, mount systems etc… just like the Gnome Disks app, even when i chowned defaultuser for the SD card, some Jolla Store apps still could not access the data on the SD card, for example kdbx password database
  10. the android storage is separate from C2 sailfish storage, it would be nice to have an option for full integration, where images taken on an android app are simply saved in the pictures folder for sailfish os, using permissions (in general maybe have unified permissions between android and sailfish os)
  11. OpenVPn doesn’t work, does not connect for imported profile conf, does not ask for password, I don’t think it uses or properly sets up the routing doesn’t work for some openvpn configuration files like Purism One Open VPN, and for those where it works e.g. proton openvpn it requires use of credential pass.txt file that stores the user name and password
  12. I tried to copy 32GB from my SD card to the Sailfish OS documents folder and it claimed to be out of space, even though there was plenty of storage remaining, so copying many large files fails, or $home storage isn’t setup properly by default
  13. the sailfish OSK is awesome on this device no delays or lag (other than decrypt and login OSK) and rarely mistype, it would be nice of course if it had a auto suggest or complete feature but that is secondary

OpenVPN certainly does work. I have my Jolla C2 set up with ProtonVPN. I’d make sure you have set up an openvpn credentials file and that it is using that.

in the US you can send SMS messages but mobile data connection mostly crashes, sim disappears, it shows 2.5G as network indicator

I don’t think it was ever advertised as being able to support all the bands in the US, or really any support in the U.S. at all. It (well, the Reeder S19 Max it is a rebadge of) supports common bands 3 (1800 MHz), 7 (2600 MHz), and 20 (800 MHz) for LTE (listing those as they are used across both Europe and U.S.) but YMMV on which carriers in the U.S. support them and most importantly, where (geographically) those bands are supported. It’s not like an iPhone which designed to work across basically the widest range of bands around the world.

Update:

I have used a credential file (using username/password) for setup as well, that did not work. Since you got ProtonVPN to work I have that too, and it uses username/password so I give it a try (if you have any tips to share that would be appreciated). The other provider Purism openvpn config files did not work. They work fine using the debian networkmanager though on my desktop and librem 5, and work fine on MacOS, iOS.

Ok I tried proton openvpn and in this case the config file after import and vpn activation correctly asks for user name and password. However, after entering username and password vpn does not connect. Also even though I have remember credentials selected it forgets the username and password previously entered, It reprompts to enter empty user name and password after failed connection, what it should be doing is save the information. Forgetting the open vpn credentials also was an issue in Sailfish OS about 6 years ago when last I tried to connect to an open vpn tunnel, this does not appear to work either.

It does finally work when using a pass.txt file with proton vpn and I am connected woot!! Wish the entering username and password prompt would work though.

#778

I know but it can work probably needs some development though, i can receive SMS and send and the bands available here/network is detected (just crashes all the time).

Here and then I am reading about C2 having a good camera. I am not satisfied… But maybe I mis something?

Are you using SailfishOS’ camera app? Which settings are you using? What kind of fotos are you taking, e.g. outdoor, indoor,…?
Are you using Android’s OpenCamera? Which settings?

#780

Not happy about the camera also. Too cold colors with Automatic WB. In some cases selecting Fluorescent makes picture more warmer. But after closing camera app and when I re-open it, it still shous WB as Fluorescent, but actually it has turned back to automatic.
And don’t understand this GPS thing. I turned on my old Jolla 1 and I do not have to run GPSInfo app, to add locations information to pictures. Should gpsd-process to the job and it’s not working correctly on C2?

#781

Hello, I confirm that openvpn works with proron vpn. On the C2. And wireguard works on the experia Xa2. Xperia 10 III and 10 V. Not yet tried wireguard on the C2

Have you tried installing microG? You can find it on F-Droid.

#783

Installing microG (directly from the microG website, FDroid for me did not have microG) and/or Google Play services does not work. Soundcloud still has the error, and when playing a song crashes now. Before it after selecting play button the button after a short while would just go back to pause, without any sound.

I tested the speed with the same sim card I did it several times and the result is pretty much the same on the same phone. Tested on a C2. Then on an Xperia 10 IV. Then on an Xa2 The Xax2 is faster than the C2 and the Xperia 10 V is the fastest

Honestly I’m wondering the same thing as well. I was half expecting Pure Maps to pick up my location, but either there’s a user-specific problem (me) or I’m missing some key component here. Location is on, tried with and without high-precision, tried with and without wifi (so mobile data only), installed GPSInfo and it doesn’t pick it up either. What is the magic incantation that folks have used to get it working, assuming it does?

Are you sure that is on 4G?
I get about that on 2.5G with Wi-Fi.

#790

Yes it does, but in my case on a Xperia 10. No idea if this also works on the C2.

File is vendor/etc/gps.conf, there change

# NMEA provider (1=Modem Processor, 0=Application Processor)
NMEA_PROVIDER=0

to

# NMEA provider (1=Modem Processor, 0=Application Processor)
NMEA_PROVIDER=1

Also you may want to change this:

# NTP_SERVER = time.google.com
NTP_SERVER = ptbtime1.ptb.de

to request network time no more from Big G.

I just did a flow test again between the xeria XA2 ultra and the C2.
The results are pretty much the same as last time. With the same sim card and I’m not on wifi but on 4G

#793

Using the latest release on the C2 (5.0.0.43) I have a VoLTE entry in the network setting.
By using 4G, I am able to register on it (Bouygues Telecom, France). Is there a way for me to test that it is indeed working ? a complete procedure ?

I cannot stay in 4G as I do not receive / send SMS in this mode, I need to stay in 3G. Also, it seems the Android app support can receive internet through WiFi, but unfortunately not through 3G / 4G yet.

I can’t wait for the C2 to become my daily driver, unfortunately it is not ready yet.
