Oooh. Ohhh. Lineage 15.1 (testing)

Help Fairphone 2
122

Once you open an APK, it asks for it. I wasn’t able to grant it to the default “Files” app, though, in LOS 15.1 on my Nexus 4.

I’m actually on latest unstable F-Droid in my Nexus 4, which solves various issues in Android O (e.g. repeatable automatic installations).

123

I had the secondary phone running 15.1 with me all the time during the course of last week and used it for almost everything I normally do on my main phone (except messengers).

General observations

  • Battery consumption seems about the same as with 14.1 for my pattern of usage. I would say it looks like a bell curve with peak around 1.5 days with rare cases where the battery only lasts slightly less than 1 or slightly more than 2 days
  • I haven’t really used the built-in apps, so I can’t comment on them

What I like/has improved

  • Now one additional row of app icons on the home screen by default (and can be configured)
  • boot time seems slightly reduced

What I don’t like/has gotten worse

  • In 14.1 when tapping the “energy save mode” icon in the quick launch area it used to open an “overlay” (not sure if that is the correct term) that also showed a graph of the battery consumption. The quick launch icon now is just a toggle and to see the graph from the battery settings a lot more taps are needed

I guess I need to check what is new in Oreo because I feel I didn’t notice much difference :wink:

Do you have a post somewhere, explaining how you achieve >1 day battery autonomy?

125

No, I don’t have a post about battery optimization. A few things that are relevant come to mind:

  • I enable power saving + do not disturb mode when I go to bed (and disable when I get up)
  • barely watching videos on the phone; no games at all
  • checking for emails reduced to once per hour
  • most of the time not taking/uploading pictures or videos
  • WiFi and mobile data on, bluetooth + gps off
  • I basically don’t use it as a phone for calls (maybe two or three calls per month)

I probably just don’t do as much with the phone as others do. I have disabled lots of notifications and for some I set a different sound to distinguish between “potentially important” and “most likely not important”. If you pick up your phone and the screen goes on everytime the device beeps with default settings, I could imagine battery consumption is much higher. :wink:

You can long tap on the icon to go to the battery settings and then tap on the battery field to see the graph. Still 2 taps instead of one though.

I just installed the newest testing version, and I wanted to leave my story about it here:

First install - great, everything’s fine, but hey, the device is not charging! Ok, maybe something went wrong during the flash procedure, so let’s repeat this.

Second install: everything’s fine, but hey, it is not charging. Going back to 14.1, frustrated. Back at 14.1, the device is not charging at all!

But it is hot as h :japanese_ogre:

Ok, let’s cool it down. Now the charging works.

Re-flash 15.1, taking off the backcover, and leaving the phone on the cool kitchen sink. Et voila, the device is charging with my special heat sink…

Lessons learnt for today: FP2 protects itself when it becomes too hot and will not charge…

Love your heat"sink" :smiley:

New build available (see 1st post).

Fixed:

  • FM radio works again
  • Notification LEDs should work now

Last remaining issues (at least for 8):

  • Some users here have noted strange behavior with MultiSIM (PIN requested randomly). Can someone confirm that this is not working? I don’t have two SIMs at hand this week.
  • Backlight does not power on again in Offmode charger (but it keeps charging). The battery is shown for a few seconds, and then you cannot bring the battery anim back on. Seems to miss a kernel fix for this.

The other reported issues:

  • Reboot into recovery: I cannot reproduce this. Can someone confirm that this is broken?

New cam module issues - They are not new in O and I think they also exist under Fairphone OS:

  • Camera flash not in sync with picture taking using Snap app (built-in camera app): I think this was already on cm-14.1.
  • Shutdown make it reboot: This is also with Fairphone OS apparently and not new in O.

Will check. Unfortunately there was just one mirror and that’s providing only 40KB/s :smiley:

131

Yep, instead of booting to TWRP, the phone boots to the launcher/desktop. I have the new camera modules.

I’m a bit concerned about the encryption situation. For now that’s a dealbreaker for me.

The LineageOS 15.1 test build can encrypt. That’s fine.
Current TWRP cannot decrypt this then. That could well be. But why?
What changed from LineageOS 14.1 (Android 7.1) to 15.1 (8.1) at this front?

What concerns me here is that the internet reports for months now that the respective TWRP on several devices can’t decrypt Android 8.1 encryption … and somehow there was no noticeable movement apart from a few fixes in non-official TWRP builds for certain devices. And now here we are on the official LineageOS/ official TWRP device Fairphone 2 with the same problem.

I somehow imagine a scenario now where the LineageOS side would think “Well, fix TWRP then!”, while the TWRP side would think “Well, fix LineageOS 15.1 then!”.

I do my system backup with TWRP. I briefly looked into other ways (dd-ing the encrypted partition block or using adb backup), and I’m not enthusiastic about moving away from the very convenient TWRP backup.

So, any definite idea who has homework to do? LineageOS 15.1 or TWRP?

TWRP has.

Do I have to wipe to install this build?
I could test the 2 SIM PIN problem again.

Another difference to 14.1: I cannot define, which of my screens should be my home screen. The system always chosses the most left screen. Does anybody know how to change this?

136

No, you don’t have to wipe.

Press and hold on a home screen until the screens zoomout and you get the various options to add widgets etc. On the tiles above you can switch between your screens and you should notice a little house. Tap this on the screen you want to be your main screen and you’ll see the circle goes white… and that’s it :slight_smile:

So, I took the plunge this morning and installed since all the big bugs are off the list now (and I don’t have the new camera modules anyway)

I was on an encrypted device, so have started from scratch which I was planning to do at some point soon anyway!

Everything seems to be a-ok.

I’m a little confused about encryption though, as I do need to use encryption. Should I flash the recovery from post 1, then encrypt and that should work fine?

Try to encrypt, it should work.
If it doesn’t, start from scratch and take the steps given here.

As long as you don’t need TWRP to be able to decrypt the data partition (which TWRP can’t as of version 3.2.2-0), everything should work fine.

With the version of 28th I still have one problem with the LED. I’m currently charging while the phone is on, but the LED was not lit. Then a notification came in, the LED went on, just to go off after a short while. Now, several minutes later the LED is on again. And just as I type it went off.

Edit: and I can confirm that adb reboot recovery and adb reboot bootloader both do a normal system boot (I have TWRP 3.2.1).

141

OT: Can 3.2.2-0 decrypt 14.1?

142

Yes. No problem there.
