Rotation lock for specific apps
-
I would like my Phone app not to rotate - every time when I try to end a call I have to chase the red button as the screen rotates sometimes even a few times after I remove the device away from my ear. Is there such a possibbility? If not, are other people interested in this feature? Can this be done in-app, in Settings or in a third app like UT Tweak Tool?

If you have to chase the button, that sounds like an issue.
I wanted to say, maybe it's because you hold the device more or less horizontal and then just by tilting it a little it turns. But I just checked on my Nexus 7 and I have to tilt it approximately 30 degrees to make it turn. If anything, I think my device is not rotating enough and not too much!
Do you have rapid rotations in other situations as well or just when ending a call? How are you holding your device when it does it? Are you bringing it down from an upright-next-to-the-ear-position down to almost-horizontal? Or more like using a headset and pulling the device out of your trouser pocket where it was head down to have the headphone jack on top? Does the behaviour change with different angles/ positions?

Just to get it out of the way first: You know there is a rotation lock for the phone in the top drawer? But I assume you want to control it per app, so then that doesn't help.
You can hack the supported orientations on a per app basis. If I remember it right it's in the .desktop file in ~/.local/share/application or so. There can be a
X-Ubuntu-Supported-Orientations=
which can have a comma separated list ofportrait,in-verted-portrait,landscape,inverted-landscape
(all from memory, could be spelled differently). I don't think there is any tool to help with short of an editor. -
@doniks Thank you, that is great suggestion to edit the .desktop file. It's just that I don't find the specific file for the phone app. Could you help me with the location of that file?
Yes, it happens after I take the phone away from my ear. So from a diagonal (maybe horizontal) postion, I try to get it to vertical so that with one hand (the left one) I could hit call end button with my thumb. But instead of the app just to rotate to the portrait view, it does sometimes few more rotations - as if in my switch from landscape to portrait I flipped the phone on the back and all the rotations must be executed in order. It looks like I phisically rotate the phone faster than the rotation of the display is executed. So, if the sensors recorded several rotations (I guess because inertia) then all the rotations must be displayed. In the end it lands on portrait view but it does this "dance" sometimes.
My device: Pro 5 (turbo).

I can't figure out how to make it portrait and inverted though. I'm sure this worked like that at some point, but I can't figure it out now: https://wiki.ubuntuusers.de/Baustelle/Ubuntu_Touch/Snippets/#User-Interface-Rotation

I think you should file an issue

@doniks Again. Thank you.
Regarding filing an issue, I wanted first to know if other users are affected by this.

Good point. I don't have a sim card, so I'm not affected
-
@doniks hmm I wonder if we should keep in mind this portrait only behaviour for other phone apps (v.g. SIP ones)

Well, not for me please. I do want to be able to use apps in portrait. But I admit that I'm biased, because I use a Nexus 7 (7 inch tablet) which I hold landscape most of the times. Apps that force an orientation break my user experience. This was very painful for me a few years ago before Canonical improved the rotation support. I don't have a UT phone, but I think I would also like to be able to use a UT phone in landscape. I know that I suffer from Androids inability to provide a proper rotation experience.
I think, forcing portrait is a nice hack for @mihael's problem. But the actual bug is: "Too rapid rotations". I don't think "force portrait" is an apropriate fix for this. It's more a workaround that throws away a bunch of valid use cases. The device should do The Right Thing (tm) also with a SIP dialer and that is: Give me a good user experience on multiple form factors and orientations.
Btw, can you reproduce the too rapid rotation behaviour that @mihael observes?
-
@doniks yes, I agree with you of course. I was just thinking out loud and I should have explain myself better
After some quick tests, it seems I don't have that quick rotation problem. My Nexus 5 (xenial rc) rotates 'normal' from what I can tell, but I'll keep an eye on that.

No worries. These things need to be discussed! I don't think it's obvious what is the right thing with many of these converging use cases. That's why UT is the best in class. Because it's hard
-
@doniks In /usr/share/dialer-app/dialer-app.qml there is a
automaticOrientation: false
setting - so it is set to false... -
@doniks As very quick aside what version if Ubports are you on the nexus 7. Mine defaults to portrait oonce the unlock code us entered and does not go back.Mine us 16.04 rc. Think oughts the tablet not Ubports side want ti check. Thanks

-
@doniks It means that is the only thing I found in dialer-app files about orientation but it is already set to false...
-
@mihael I'm still not following. Did the
X-Ubuntu-Supported-Orientations
not work? Are you looking for another workaround? Is it rotating now withautomaticOrientation: false
? Or not? Which values in the desktop file?I'm lost where we are right now and what we're talking about ...

Well, I have the images from ubports server for Nexus 7 gsm (deb!). 16.04, not sure now which channel (devel? rc?), haven't updated for a few weeks and I'm "between laptops" so I can't easily check and it's ... a ... bit ... uhm ... an adventurous installation because: https://github.com/ubports/ubuntu-touch/issues/643 However, it rotates every which way I want it to. (Except the login screen, but I think that rotates for no one). Happy to discuss further, but then let's jump into a separate thread shall we.
-
@doniks Yes sounds great. Working most of the day so will start one later in the support section when free.
-
@doniks Sorry for not being more specific and thank you for your patience.
I didn't modify anything. The setting that I described is as I found it and I thought that if it is already set to false, there is no point in me setting it to true since what I want is that the app would not change orientation automatically.
-
@mihael ah, ok. understood. But, well, I don't know whether or what that variable does. I'm not really familiar with the dialer source code
-
As dialer-app already has automaticOrientation set to false, and specifies only portrait as supported orientation in the .desktop file, it should not be rotating at all.
This is a bug. An extremely complex new feature, such as locking rotation configurations at app level granularity, is not the right fix.
Is there an open issue about this problem? If not, please report the issue in github.
