[OFFICIAL] LineageOS 17.1 for Xperia Z3

[jw243]

Thank you very much for your reply. This indeed fixed the problem.

However, I was extremely hopeful, that with this fix, my other rotation problem would be fixed as well, but it wasn't. Last night, before putting the phone into the charging dock, screen rotation worked flawlessly. And upon putting it into the dock, the screen switched, as intended, to landscape. However, when I took the phone out of its charging dock this morning, rotation of the screen was not possible anymore.

Could this bug at least be related to the bug above? Maybe it only appears on encrypted phones? Or it is related to using a charging dock?

I would be so greatful, if this bug would be fixed. I am actually considering exchanging the Z3 for another phone as this bug is so annoying.

Just to let you know: The bug has never appeared in stock rom. I have set up my phone several times by reflashing stock rom using FlashTool and trying it for a few days. After that, I followed the lineage installation instructions meticulously, and the bug appears everytime.

i ve been using lineageos 17.1 with unencrypted phone, never had a rotation problem (although at some point i had noticed a feature to manually rotate the phone via a pop up button, which was gone in later versions).

however, i have noticed this strange behaviour... left earbud is ont working. ok, problem with hardware i hear you say... thats what i thought... and then, after installing waze with really loud directions, the earbud came back to life! holy sh*t! now, i keep waze just to wake up the earbud!

talking about quirks... lte sometimes doesnt re-enable unless after reboot...

Well, I was hoping that myself, but it was became quite quickly that both topics did not have the same root cause. To me, this is annoying as well.

At least I am able to reproduce the auto-rotation issue quite stable now, and it seems to not be related to encryption nor to any kind of charging dock. It seems to be related to some legacy library.

Exactly

Well, I still think it's hardware related. Just guessing, maybe there is some impedance/resistance measurement taken before the channel is switched to the earbuds. Try cleaning the connector carefully with some anti-corrosive cleaning fluid for electronics.

To all users experiencing the auto-rotation issue ("Android [Screen] Rotation" stops working after 1-2 days usage):

@NeoArian suggested to try to replace the sensor binaries. If you want to support the bug hunting, you can replace
sensors.msm8974.so
and test this yourself:

• Download the last AOSP binaries from:
  

  Software binaries for AOSP Marshmallow (Android 6.0.1) - Legacy - Sony Developer World

  developer.sony.com
• Boot to recovery, mount /system rw
  • If you use Lineage Recovery:
    1. enable ADB,
    2. adb shell mount -w -t ext4 /dev/block/mmcblk0p23 /mnt/system
• exchange vendor/lib/hw/sensors.msm8974.so with the file (same name) from that zip
  • adb push sensors.msm8974.so /mnt/system/system/vendor/lib/hw/sensors.msm8974.so
• reboot to system
• normally use your phone and wait a few days w/o rebooting if auto-rotation still works...

Unfortunately, there is no guarantee that this will help, but at least it is something we can try.

[UPDATE 06Mar2021] Well, we now know that this is not working, further analysis is ongoing.

How to disable always on display? Turned on, don't know how

maybe settings->advanced->screen saver->when to start->never

On my phone, the rotation problem definately seems to be related to charging (in the dock). This morning, it was exactly the same: no rotation after charging in the dock, just as the last time.

adb shell mount -w -t ext4 /dev/block/mmcblk0p23 /mnt/system

Unfortunately, this command didn't work since /mnt/system didn't exist. I was able to get the file to the correct destination with the correct rights using Material Files, though.

The first thing I notice is that rotation seems to be much smoother. I will report, whether rotation will still be possible after the next charging.

Thanks for all your effort.

I took the phone out of its charging dock this morning and again... rotation did't work! However, all sensors still work as shown by SatStat.

My guess is that it is a problem of the lineageOS build, not of the vendor libraries. Somehow, the rotation module does not interact with the working acceleration sensor.

I feel, that the following circumstances may play a role in this bug:

• encryption of the phone
• charging (using the charging dock)
• start the charging from below 15%

I will do further testing on this.

 

[Mr.Tom_Tom]

Thanks @jw243 for your contribution to resolve this issue!

Regarding your comments:

• Yes, I can confirm that simply replacing the sensors.msm8974 library does not help. I experienced that myself yesterday.
• adb shell mount not working: It's working if you use Lineage Recovery, for TWRP the mount path may be different
• encryption of the phone: I can't rule that out but it is quite unlikely
• charging: I don't see coincidence here, I think I saw the issue happening overnight without charging
• start the charging from below 15%: can't confirm that, but low bat could somehow be related
• the rotation module does not interact with the working acceleration sensor: The sensor itself should report orientation independent from the raw accelerometer values. Consequently, a working accelerometer does not mean that the orientation feature is working as well.
• [...] it is a problem of the lineageOS build, not of the vendor libraries: Well it seems to be the interaction between Lineage or AOSP in general and the libraries.

It could be helpful to get some logs shortly after orientation stops working.

Hey everyone, just ordered a supposid "new" unopened old stock xperia z3v out of nostalgia and was looking through reviews and forums until it arrives. came upon this tread thinking I might be able to somewhat update it but being a verizon variant, I'm not so sure. Anyone have any insight if this LOS ROM would work on the D6708? TIA

I'm really enjoying Android 10 on the Xperia Z3 but I wonder how can I update the kernel, I need some resources I used in the Xperia SP, for use with mhl (KCall Support so I can turn the smartphone screen off while hooked to a TV) and even using DriveDroid which the current kernel won't allow me to, so I can't emulate a CD drive with the current older Kernel. I saw an updated one for MM, but I'm not sure if that would work with this rom.

Has anyone tried BiTGapps for the Z3 on Lineage? Wondering if its still working as that threads now closed & the download links are dead! Anyone got a backup? .. Also has anyone here experienced microG ? need to know what the best option is for an appstore,.. Always used minimal Gapps in the past but curious about these alternatives.

i was using bitgapps, but too much work after each updateof the rom i had to reinstall them. i think i still have some version of 4-6 months ago, if you re interested...

I am pretty sure it won't work, sorry for that. There seem to be quite some differences with the hardware compared to a D6603. If you want to try building something yourself I'd be happy to hear if you are successful.

I'm really enjoying Android 10 on the Xperia Z3 but I wonder how can I update the kernel, I need some resources I used in the Xperia SP, for use with mhl [...]

It's hard to update the old kernel sources, but I would not give up hope that someday we might be able to run our devices with a mainline kernel. MSM8974 is pretty well supported already.
