Apparently the problem has been solved a while ago for the POLLUX flavour but not (yet?) for POLLUX_WINDY (WiFi only version).

To be really sure I left the device with GPS Test running right by the window where it easily finds a GPS fix if one of the older Nougat ROM versions is installed. After 2 hours still not a single satellite showing using GPS Test.

OpenWeatherMapWeatherProvider

Up to now LOS didn't manage to update any weather provider for anything above 14.1 although this is an essential part of the cLock widget. Even after this announcement on Reddit on January 6 there weren't any follow ups.

Today I found this: https://blogs.nologin.es/rickyepoderi/index.php?/archives/169-OpenWeatherMapProvider-needs-to-be-compiled-again-for-Lineage-15.1.html

This guy has compiled OpenWeatherMapWeatherProvider for 15.1 and gives instructions on how to compile it for yourself.

Haven't tried it myself yet since i'm still on LOS 14.1 with my Xperia Tablet Z. But I'd appreciate it if someone gave some feedback if this actually works ;)

If that's so easy I wonder why this hasn't been done officially by now...

I want to try Iptv on my tablet, here i am using mx Player with a Fritz Box. The rdp file plays on my Smartphone but not on the tablet. Before installing Lineage it worked. Maybe it has to do with multicast? Thanks.

Hi guys, you can update the thread and mark it as OFFICIAL with updated download links,

Lineage OS is now official in 15.1 for both Xperia Tablet Z LTE and Wifi

If you wish to be able to use OTA updates (just been shifted from nightlies to weeklies last week) you must switch over to the OFFICIAL downloads from lineageOS.org for LTE version aka pollux or WiFi version aka pollux_windy

There is a thread on reddit which is about this problem.

Someone opened an issue on gitlab: https://gitlab.com/LineageOS/issues/android/issues/156

Maybe GPS not working gets more attention if more people comment or upvote there.

[MENTION=3181149]fireflygwyn[/MENTION]: did you by any chance comment the open issue at gitlab? If not it probably could help to draw some attention to the case if you did...

[MENTION=7827892]CaHbKaUp[/MENTION]: as you are listed as a maintainer on LineageOS.org's Device Info page:

Would you mind sharing some info in regards to a possible upcoming LOS 16 build? Or will 15.1 be the end of the line?

Will the OFFICIAL 15.1 version be maintained at least for some time?

Are there any plans in regards to that GPS issue mentioned above? Apart from a gitlab bot trying to close the issue last week there aren't any traces of activity.

I'm not the person, you're asking, but let me reply to your quote, as i have some, i suppose useful information regarding your questions.

GPS is working on pollux unofficial today's build from OP.

As far as i know, the issue with GPS on windy is mainly in absence of pollux_windy devices for maintainers to debug and test.

Without actual devices in hands, it is very difficult and time consuming to do smth about it.

Pollux version was fixed much faster because ROM's are mainly tested on it and a practically all maintainers have pollux version tablet.

Official nightlies are usually maintained untill new version of android are starting build. Like 14.1 disappeared from LOS official site several weeks ago, when 15.1 nightlies started to build. So don't worry about official nightlies of LOS 15.1, the will be built for at least a year, i suppose.

As for 16.0, source codes are available on github for LOS/RR/CR. Some internal test builds of LOS exist for quite some time already.

The feedback is quite positive, especially comparing to early 15.1 builds, but still some things are not working as they should now and need to be fixed (in a developer spare time) so nobody will give you a definite release schedule. But there is a hope, that by the time google releases android 10, we will have good working builds of android 9 (16.0) :fingers-crossed:
[Xperia Tablet Z Original Android Development] lm089:
Many thanks for all that info. Understand that it's difficult solving a problem without having access to the device. Let me know if I can be of help, like getting logs or whatever.

Differencies between this and original LineageOS

Hi,

Nope, the Gyro is working for me as well.

Lineage provides also a Oreo 15.1 for our Xperia tablet Z device. Does this the same as the build mentioned by this thread?

If not, what are the differencies?

With the original LineageOS 15.1 nightly build I'm facing a problem that the display cannot be reanimate when the display is turned off by the on/off hardware button. Are someone also recognize to this issue?

Thanks

[Xperia Tablet Z Original Android Development] jeromelec:

Which issue? Gyro or display issue?

After a recherche in the LineageOS issues on GITlab there is still an issue that describes the "Display issue" mentioned above:

https://gitlab.com/LineageOS/issues/android/issues/523

As workarround you must turn off the "extended screen" on our device.

No. This thread contains custom builds with some features not available on official nightlies due to some LOS rules&restrictions.

TWRP gone?

Today I tried to update my device from the 2019-04-21 build to the most recent. Therefore I wanted to reboot into recovery (primarily to make a backup before but also because automatic update doesn't work anymore since many builds).

But the screen stayed black and at first I thought the device was dead. I could make a hard reset and reboot into the system. But every attempt to boot into TWRP failed. Either it just booted into system or it stayed black until a hard reset.

TWRP Manager tells me that a recovery is not installed.

I have no idea what is going on. How did TWRP suddenly disappear?

edit: I have the official LOS installed
[Xperia Tablet Z Original Android Development] Rootk1t:
If you have Magisk v19 installed, it is not compatible with this firmware up to date, it prevents entering recoveries.
[Xperia Tablet Z Original Android Development] brodo:
Thank you, that is the case.

At least I could enter recovery once after flashing TWRP 3.3.0.

Is it possible to downgrade Magisk to v18? Or will this break any modules that I upgraded after installing v19? Some of them I had to reinstall because they didn't work anymore after installing v19.
[Xperia Tablet Z Original Android Development] Rootk1t:
Well, if you fixed your problem with entering recovery, i think you can do nothing.

If not, then enter recovery, flash Magisk-uninstaller-20190204.zip, after - flash Magisk-v18.1.zip, wipe cache/dalvik and reboot to system.

For me it didn't break any modules.
[Xperia Tablet Z Original Android Development] brodo:
It's not exactly fixed if I have to reflash the recovery (and boot partition I think) every time I want to access it. But I will try downgrading Magisk like you described!
[Xperia Tablet Z Original Android Development] lm089:
Downgrading does help. We can stick with 18.1 for a while hoping that the xperia issue will be fixed sooner or later.
[Xperia Tablet Z Original Android Development] lm089:

[Xperia Tablet Z Original Android Development] lm089:
Sorry for bringing this up again: on "change list" at LineageOS.org numerous topics appeared over the last few days, so I assume that there might be an update over the next weekend. I may be wrong but none of the changes seem to be related to that Magisk conflict discussed above. Does any one have infos about that?

To the maintainers / devs: please be assured that I'm very thankful for still being able to use a near 5 year old Xperia device, and I'm not trying to push anything. Main reason I'm asking: I'm a bit torn between upgrading to LOS 16, then having to deal with the "screen orientation" flaw, or staying with 15.1, then having to live with an outdated Magisk version.

Changes:

June 2019 Android security patch

Magisk issues fix
[Xperia Tablet Z Original Android Development] lm089:
Switched to this ROM from LineageOS 15.1 OFFICIAL as that started partially blocking Magisk after the latest update. I'm very happy to see that with this ROM here Magisk modules continue to be loaded and run; I'm experiencig the occasional fc of various apps, but that's harmless (it's very random, never the same app twice so far; as soon as I'm able to find some regularity I'll create a logcat and post it). Once again, many thanks for your continued support.

One thing I'm observing is that with this ROM here is that there's a big delay when flipping the display on orientation change. It's taking much longer than with the official build, I mean.

Again this is absolutely harmless and nothing to complain about, just want to report it.

If someone's interested in that and probably needs some kind of log please let me know, then tell me what kind of log is needed.

[Xperia Tablet Z Original Android Development] Rootk1t:
SGP311 will not work with POLLUX ROM at all, because Pollux = SGP321.

As for MHL support, it is not only ROM dependent, but sometimes also build dependent too. As far as i remember it was not working on official 15.1 LOS builds. But feel free, to try unofficial ones. I can't help you with that, because i don't have mhl adapter for test.

That's unfortunate; I'm still using mine daily and Lineage was keeping it alive. Anybody have recommendations for a newer Android tablet of the same size?
[Xperia Tablet Z Original Android Development] DHGE:
SAMSUNG Galaxy Tab5e

I bought my wife the LTE version since it is the only available here in South Africa and there was a Black Friday deal.

compared:

- stunning high resolution screen

- 30% (feels so) worse wifi reception/reach, dunno if the wifi only version fares better

- 30% (feels so) better speed/smoothness - not much if you count in 5 years HW development from 2014 to 2019

- very thin/light and top finish, beautiful piece of hardware

- very good battery life, you might get away charging only every other day with only browsing and email use

- LineageOS already available

I might get the wifi version in Europe as a replacement for my SONY/Lineage abandoned Tablet Z4 (long before the Lineage support for Tablet Z dropped).

So far I am waiting for a tablet with specs (do not need the stylus) like the SAMSUNG Galaxy Tab6 and 11"-12" screen.

The Tab6 is not worth the price over the Tab5e for me: it would be only much better speed and a tad less battery life.
[Xperia Tablet Z Original Android Development] Sparky_McBurning:
Just looked at the specs for the Tab5e, and while the size looks perfect, I use the headphone jack daily so I don't think it will work. Thanks though!

Edit: Forgot about usb-c to 3.5mm dongles. I think this has just about everything I want aside from a few nice to haves (like IP rating). Great suggestion!
[Xperia Tablet Z Original Android Development] guhvanoh:
[ot] I got my S5e WiFi to replace my Tablet Z which I buggered up. I didn't get the S6 since I couldn't justify the difference in specs/price. It just wasn't value for money in my view for what I use a tablet for. I primarily use it for email, XDA, telegram, zoom & WebEx. It's good, I like it apart from all the Samsung apps on it which I don't use or want. It's still stock as I can't be bothered to go thru all the hoops to root and put a custom ROM on it. There's more support for the WiFi version than the LTE version on XDA. Battery lasts about 3 to 4 days with my usage. Samsung has 'promised' an upgrade to A10 this June. If it comes and I don't like it I'll probably bite the bullet and root and put LOS17.1 on it. Hope this missive helps. I may even work on bringing my TabZ back to life. At least my Z2 and Z5 premium still work even tho I don't use them. Sony TV and 2 Blu-ray players are in use, the Sony Dolby S cassette deck is broke... Had to bring this back to Sony since we're way OT here. [/ot]

:(

Any solutions?
[Xperia Tablet Z Original Android Development] Rootk1t:
Did you check carrier/mobile data settings?
[Xperia Tablet Z Original Android Development] tres_linguas:
All the settings are correct. The issues in detail:

- every couple of seconds signal is lost. Once this happens and signal is recovered, no mobile data any more

- PIN has to be entered over and over again (connected to signal loss)

- if mobile data is there, it's H+ maximum, even though the setting is LTE

Issues can't be connected to the SIM, I tested the SIM in my phone and none of these issues there. Can't remember having had issues like this on Oreo before (with pollux), either

Once there is an August build I will update and see if it persists

So Mobile Data working fine with you guys?

EDIT: resolved by playing around with some of the settings. Only 3G works stable but thats OK with me.
[Xperia Tablet Z Original Android Development] Rootk1t:
It was released. Can you check if the above mentioned issue is there or not?

If it is still there, you can report it in the LOS 16 thread.

It works well with 3G as preferred network type. Once I select LTE, signal comes and goes and is not stable. So I'll leave it on 3G preferred.

Interestingly, even with this setting sometimes I get LTE (it actually even shows LTE+ ?). But usually it shows H or H+

Attention Firefox users!

I just wanted to make Firefox users aware to not update to the most recent version (79.0.5). It will result in a crash of the whole system (reboot). See the related issue here on github. Since the Firefox devs won't fix it, the only solution is to upgrade to LineageOS 16 (will do now).

@CaHbKaUp or anyone else, can you please tell me if this rom has overclocking enabled/ability to increase the freqs for the cpu/gpu, like the 14.1 rom? I'm currently on the 14.1 rom, using oc with kernel adiutor for that little bit of extra performance, I'm mostly fine with the build, but Youtube 60fps videos stutter a lot and from what I saw, the 15.1 rom should fix. I would install it but I want to know if I can raise the freqs just like in 14.1, since every bit of extra performance helps with this old tablet.
[Xperia Tablet Z Original Android Development] Tonnyy24:
Edit: nevermind, I installed Lineage OS 15.1, the overclocking options are available in Kernel auditor, weird thing is that the benchmark scores in Geekbench 4/3Dmark Icestorm Extreme are ~10% lower with the same settings compared to 14.1 version. Sadly, the most important thing for me, Youtube 1080p 60fps clips still stutter like hell :( Was hoping it will be fixed with this rom version, but it seems not. Anyways, thank you for your work, it's still something to have Android 8.1 on this old tablet.
[Xperia Tablet Z Original Android Development] Rootk1t:
The problem is not in ROM, but in youtube app itself.

Try youtube vanced.
[Xperia Tablet Z Original Android Development] Tonyy24:
That's exactly what I am using, Youtube vanced. Stutters like hell in 1080p60fps regardless of codec avc/vp9. And I figured out why the benchmark scores are lower compared to the Los 14. 1 rom, the gpu overclocking isn't working, I can select 487mhz gpu but it' s only visual, it won't clock higher than 320mhz. The cpu oc is working fine...
