You need to have a ps4, with remote play you can use your tablet as a display and control the ps4 with a controller

Any plans to move to Oreo or Pie now that official Nougat builds are coming to an end?
[Xperia Z4 Tablet Android Development] TracerBullitt:
Will that even be possible for this device?
[Xperia Z4 Tablet Android Development] belrik:
The hardware is capable, it's just a question of whether Sony has released any support for newer kernel and Android releases.
[Xperia Z4 Tablet Android Development] 5t0rmr1d3r:
The only question there is, is there an dev with this device and capacity to solve the build problems. If even the old sony xpefia sp is getting oreo...
[Xperia Z4 Tablet Android Development] jelbo:
It should work with Magisk (which works) and the Sony Framework module. Here are some instructions.
[Xperia Z4 Tablet Android Development] zzcool:
is this a true port for all of android not just pictures and videos
[Xperia Z4 Tablet Android Development] mjchung:
Hi, I apologize if this issue has been settled, but I was wondering if anyone has figured out how to enable multitouch gestures like two finger scrolling with the BKB50 keyboard? I just installed LineageOS this morning, and it's such a breath of fresh air compared to stock! So far, the scrolling issue is the only problem I've found so far. Serious thanks to the devs and community working on this project.
[Xperia Z4 Tablet Android Development] Medizinmann:
Hello,

any plans to go for Lineage 15.1 or 16.0?

Would be sad if the Z4 would be dead now.

The older Tablet Z got the upgrade to LineageOS 15.1

Greetings,

Medizinmann
[Xperia Z4 Tablet Android Development] DHGE:
binaries for LOS > 14.1?

Looks like you have to do it yourself.

The LOS-Wiki says: "build instructions available"

Problem might be the availability of drivers. For SONY the device is "legacy" with the latest binaries left at Nougat Android version.

I have no idea if at all or how difficult it is to adapt them to newer Android versions.
[Xperia Z4 Tablet Android Development] torben5247:
I am having the same question....

Maybe we should arrange some kind of bounty?? for paying a developer for a pie version for the z4 tablet.

The z3 tablet are having a aicp 9.0 version....

So it is strange that no developer are having a z4 tablet.

Anyone having experince with creating a bounty?

Or is it illegal???

Kind regards Torben5247.
[Xperia Z4 Tablet Android Development] Medizinmann:
Well that is (sadly) out of the question.

I neither have the capabilities nor the time to do such a thing.

Well - looking at other devices i.e. Tablet Z(Pollux) it seems to be possible. But I am pretty sure it isn't easy and a lot of work.

Greetings,

Medizinmann

---------- Post added at 06:20 PM ---------- Previous post was at 06:12 PM ----------

We need a capable developer willing to do it and with enough time on his/hers hands.

My Nexus 10 from 2012 is still up and running with LineageOS 16.0

And even the old Tablet Z has 15.1.

No, but I would be happy to contribute!

No, it is perfectly legal and pretty common on xda too.

I.e. -I remember the bounty on reverse engineering the bluetooth drivers for my LG P990.

Or bounties on rooting for several devices.

Greetings,

Medizinmann
[Xperia Z4 Tablet Android Development] belrik:
Consider asking for a combined build for the devices of this generation; the Z5 and Z5 compact phones. Andralex reminded me of this, they all use the same Snapdragon 810 SOC. A developer tackling those would be positioned to assist with the Z4 tablet.

I am using lineage-14.1-20190520-UNOFFICIAL-karin and had the same feeling right after flashing.

Installed Kernel Adiutor (root) and compared settings to my XZ1compact, could not find differences in settings or behavior. Except: bigCPUs seem to be stuck at higher frequency than the one configured as minimum (~1200MHz instead ~300).

What I did and this seems to help: Page CPU Hotplug, change setting minimum bigCPU count to 0 instead 2. That way the bigCPUs easily shut down, even when display is on. They still start on user input as expected.

That way the back stays much colder. No negative effects noticed so far.
[Xperia Z4 Tablet Android Development] moses_dx:
my tablet gets hot when playing saint seiya, it's completely stock, still waiting for a good custom rom, since I can't find a big tablet with good specs to replace this one
[Xperia Z4 Tablet Android Development] zzcool:
is this tablet dead seems like noone is doing anything with it the official rom it has has a android version thats exactly the same as this one so whats the point? i love this tablet and i really want at least oreo on it

Any new update? Rom?
[Xperia Z4 Tablet Android Development] sabar_op:
Is anyone willing to try LineageOS 17.1?

It's based on z5c (suzuran). I just finish to compile it yesterday but can't try it because my tablet is far away at home as I am working in remote site.
[Xperia Z4 Tablet Android Development] Hybel1507:
I would give it a try. Can you provide resources?
[Xperia Z4 Tablet Android Development] sabar_op:
I will send you a pm.

I would like to try it too.

Thanks

For those who would be interested I found this rom on androidfilehost look for unknownanonymous karin_windy on google (can't provide link as I'm a sub 10 posts new user)

I think it's an e.foundation port based on Lineage OS 14.1 (compiled on 20191018)
[Xperia Z4 Tablet Android Development] alex009988:
Hi. I really like to be a tester of new rom. I have karin device.
[Xperia Z4 Tablet Android Development] alex009988:
I've tested it, in a word it can be used on a daily usage, but you have to remove bliss launcher and exchange it by nova launcher and also you have to remove stock appstore and fakestore by lucky patcher and install normal gapps, you have to remove firmware bloatware by lockypatcher too.

https://yadi.sk/d/Zfxi3agx3HkLQL
[Xperia Z4 Tablet Android Development] xperiefon:
Thanks for all the infos.

Did you test [MENTION=2705776]sabar_op[/MENTION] rom ?

I couldn't as I have karin_windy device and he only provided the karin rom for now.
[Xperia Z4 Tablet Android Development] belrik:
Let us know how it goes!
[Xperia Z4 Tablet Android Development] nicke85:
I'm interested for Android 10 too, good news :)

Also i have Karin SGP771, where to download sabar_op rom?
[Xperia Z4 Tablet Android Development] torben5247:
This link is for this version : e-0.7-n-20191018-UNOFFICIAL-karin.zip and not for The sabar_op rom.

Are there anyone that has tried e-0.7-n-20191018-UNOFFICIAL-karin.zip?

Is it working, and is it also android 10?

https://androidfilehost.com/?a=show&w=files&flid=300886
[Xperia Z4 Tablet Android Development] xperiefon:
Yes, that's the one I previously talked about.
[MENTION=4127195]alex009988[/MENTION] tested it.

No news for the android 10 rom as far as I know.
[Xperia Z4 Tablet Android Development] torben5247:
i am trying the e foundation rom as we speak.

regarding the [MENTION=2705776]sabar_op[/MENTION] rom i asked for a download link and he answered that there were some boot up issues

update:

the e foundation rom isn't better than the other lineage rom´s.

My experience was a heavy battery consumption.

So i am back on stock.
[Xperia Z4 Tablet Android Development] alex009988:
Don't give up guys on waiting android 10 ROM, it definitely possible for our device. But many bugs must be fixed, I hope we'll have a good and stable rom with Android 10.
[Xperia Z4 Tablet Android Development] venki5star:
There is no update almost for a year. Where did you got this update?
[Xperia Z4 Tablet Android Development] alex009988:
There are some serious bugs in the rom that must be fixed, but there is a chance that they will be fixed. The rom is under hard development by a good man. As for now you can try Lineage 15 which is more or less stable, if you have sgp771. For sgp712 the rom could be released later too.
[Xperia Z4 Tablet Android Development] jimmy123322:
Testing.
[Xperia Z4 Tablet Android Development] alex009988:
I built my first build on my own with sabar_op guiding as los14.1 19022021 for karin (dont forget that los14 kernel doesnt support exfat) with security patch from 5 februrary 2021. I have plans to build RR, AICP, Pixel, Carbon for android 6,7,8. I dont promise anythiing, but i will try.
[Xperia Z4 Tablet Android Development] JKWR:
oops wrong thread sorry!
[Xperia Z4 Tablet Android Development] belrik:
Yes, using the los root is best unless you have very complex root requirements. No otg mouse needed for twrp, touch is working on my TWRP.
[Xperia Z4 Tablet Android Development] Jadog:
Great! I'll report back when I've completed! Thanks for the help!!
[Xperia Z4 Tablet Android Development] andralex8:
New build from today :).

Changelog :

- Lineage sources are updated

- Solved an issue with encryption
[Xperia Z4 Tablet Android Development] steevou:
Thank you andralex8 for this new version.
[Xperia Z4 Tablet Android Development] Phil_Libra:
/date can be convert to f2fs in the twrp.

can this rom support f2fs?
[Xperia Z4 Tablet Android Development] andralex8:
It's not implemented. But it should not be difficult to add with a new entry in fstab.

I'm currently fixing the default camera app (it's a LineageOS problem with landscape devices, it's not device specific). Most is done for preview and gui, just want to fix some menus and the rotated gallery also. I will see that after I finished.
[Xperia Z4 Tablet Android Development] Cissamannenv2:
Does Android 7.1.2 have issues with auto rotation? I cannot for the life of me rotate my screen unless an app forces it to its current setting in landscape or portrait.

Only way to go is using applications that force it, but even them cant use Auto as option or Force it even. Gotta manually select stuff :/
[Xperia Z4 Tablet Android Development] Nadyita:
Hey guys!

I'm a bit lost, so here's my story: I got my Z4 tablet on the day of its released and the only thing I've done was unlocking the bootloader (way back then) and installing Andro's custom kernel in order to root. After that, I was happy, but noticed I could not install any OTA updates anymore. So today, I updated supersu binaries and now the thing doesn't boot anymore. Well... doesn't really surprise me now, but anyway... I would like like upgrade to LineageOS, but it says I need to install latest Sony Nougat first. So I downloaded that flashtool but that hangs after downloading the firmware and extracting at compiling the FTF.

Does anyone have an FTF of that latest Nougat firmware that I need? I'm living in Germany if that's really important for the FTF-file, not sure.

I'm actually surprised how very complicated this is compared to my Nexus phones :eek: I mean... I just d/l the newest firmware, flash everything with fastboot, boot into TWRP and flash all ZIPs. On Xperia? Uh nope. Let's make things seriously overcomplicated...

I spent the last 3 hours googling around, trying different versions of all tools on Linux (my OS) or inside my Windows VM, so please don't tell me to google. Help :crying:

UPDATE: Now I saw that I need to *update* the flashtool before it's able to compile a ftf again. Who would have thought that the link to the 9.23.2 actually downloads 9.23.1 - flashed and device is charging now. Hope I'll be able to flash the LIneageOS after all
[Xperia Z4 Tablet Android Development] rintala@hakunila.com:
i download 33 rom using 09.23.2 and when download is ready i install 09.18.5 flashtool and then install that latest nougat -33 rom

But when i update latest lineagos screen hangs in wifi screen.. :(
[Xperia Z4 Tablet Android Development] Nadyita:
Okay, now that I managed to flash (latest?) Sony system 32.3.A.2.33 / R1D, flashing this zip gives:

Can't install this package on top of incompatible data. Please try another package or run a factory reset

Uh... did I pick the wrong Firmware? Ain't to later one to download...
[Xperia Z4 Tablet Android Development] belrik:
Some apps are just badly written and assume you're in portrait mode. That would be as they​ say "an android thing". Comes of app developers forgetting about non-phone devices.
[Xperia Z4 Tablet Android Development] andralex8:
Yes, it's unfortunately a lot less open than nexus phones, it would be a lot more easier to develop too.

You can use the ftf file I provide in the first post. It's not a complete rom, it only update some needed partitions like the bootloader partition needed to have twrp working in order to install LineageOS. It's easier than flashing a complete rom because it should not complain because the data partition is not compatible or things like that. Using flashtool is sometime hard to do because sometime you have to try an other version before it works. If Sony didn't block the updates on rooted devices we shouldn't have to do this, but we have no choice once it's done...

In summary, if you follow the instructions like if you came from a custom rom it should works.
[Xperia Z4 Tablet Android Development] andralex8:
I had a similar problem once. It was caused by a problem in opengapps that fail to activate wifi on the very first boot or after reset data. Did you installed opengapps?

If you did, you can try to install a different version of opengapps. Or you can flash the rom without opengapps then add them once you first activate wifi and add an access point. If I remember well it's also possible to quickly activate wifi with quick settings avalaible during seconds following the crash and then it works. You can search for other solutions, it's not specific to our device.
[Xperia Z4 Tablet Android Development] andralex8:
Yes, you're right, that's exactly the problem we have with camera...
[Xperia Z4 Tablet Android Development] Nadyita:
So now after flashing your ftf, I cannot boot into twrp anymore. Any other idea?
[Xperia Z4 Tablet Android Development] Jadog:
I just completed the update to 7.1.2. Everything works great! Now I have to re-install my apps. Thanks for doing this andralex8! In the future, to install any new ROM version that you release, I just complete through TWRP without doing the Wipe? Keep up the great work!
[Xperia Z4 Tablet Android Development] andralex8:
Did you flash the new twrp on the first page? You can do it with fastboot. Also notice that the key combination to boot into recovery is different because it's not handled by a script in ramdisk but directly by bootloader ( shutdown completely, then press vol down + power).
[Xperia Z4 Tablet Android Development] nsx2brz:
I just installed as well and had this same issue. To fix it, I had to make an FTF of the full Nougat image. I have an SGP712, so I used the UK version for this. After installing it I was finally able to boot into recovery by using the normal vol down + power.

Thanks very much for making Lineage for this tablet!
[Xperia Z4 Tablet Android Development] andralex8:
Yes, you can simply flash it over the previous one.

If you have problems you can try to wipe only system partition before updating and keep your apps and data.
[Xperia Z4 Tablet Android Development] andralex8:
Thank you for the feedback.

The previous way from Androplus was to press vol + when the led color changed during booting, now it's vol down and power before the boot, like you correctly did ☺. But this needs the nougat bootloader, that's why the update is needed.
[Xperia Z4 Tablet Android Development] Jadog:
So following the update, but when I browse to the file system and look at folders, I can still see folders from old programs I had installed from when I was using Lollipop. I even see all the screenshots that I took from earlier today prior to the update. I completed the WIPE before I installed the new ROM. I wiped Dalvic Cache, Data, Cache, and System. I did NOT wipe Internal Storage as I read that this should be avoided. Can you tell me if I missed a step and if it would be beneficial to go back and do another wipe?
[Xperia Z4 Tablet Android Development] andralex8:
Not necessarily.

Theses folders are data from programs. It could be the taken photographs, your downloads, music, pdf, word and excel documents,... It's usually datas we want to keep in /data/media while the other datas like configurations should be in other places in /data.

The wipe keep /data/media and remove the other things.

It's similar when you decided to use an other music player and uninstall the previous one, you don't necessarily want to remove all your music.

But it's true that some programs tend to make garbage and unneeded data there. It's boring but usually harmless. You can clean it manually if you want. Or wipe internal storage if you really want but you will loose absolutely all the datas you have (maybe with your vacation pictures and your music for exemple).
[Xperia Z4 Tablet Android Development] Nadyita:
I tried to enter recovery by issuing "fastboot boot <twrp.img>", because I didn't know that pwr+voldown works different when usb is connected or not. Doh! Well now I know and of course it works like a charm. Thanks everyone for helping!
[Xperia Z4 Tablet Android Development] Jadog:
Ok, cool. I just used CleanMaster (most any cleaning app will also do the trick) and it cleaned out all unneeded folders.

Something else I found out that may not have been reported. There is a function that I used in version 6 that allowed me to double-tap anywhere on the screen to wake the device up. Although the check-box to enable exists, it doesn't actually work. I'm not sure if this is broken for the LineageOS or if it's the entire OS 7.x in general that it doesn't work. I miss it though as I used it a lot.

Also, the Sony Image Enhancement no longer exists (used to be at settings > Display > Image Enhancement). Not a huge deal, but I thought it was worth mentioning.
[Xperia Z4 Tablet Android Development] andralex8:
It's still working and can be activate under Settings/Display/Tap to wake, maybe it was moved, I don't remember where it was before ?.

Sony Image Enhancement is a proprietary option from Sony, it's not implemented in LineageOS and I don't think somebody plan to add it.
[Xperia Z4 Tablet Android Development] azndan2:
Thank you sir! We really appreciate this.
[Xperia Z4 Tablet Android Development] HotBlack77:
Yes, new builds are always very welcome.
[Xperia Z4 Tablet Android Development] Jadog:
I am really liking the new 7.1 version - so great work Andralex! I have still been unable to get the "double tap to wake" function to work. Can anybody else confirm that it is working for them?

More importantly right now however is that Google Hangout (used for texting) is prompting to "Select SIM card". Since I have the WiFi only version of the tablet, I don't have a SIM card to choose. This was my primary way of texting and this message has made it impossible to use. Is there a workaround or fix for this?
[Xperia Z4 Tablet Android Development] belrik:
Can you double check? Because Google Hangouts have just STOPPED supporting texting from the app. Maybe this is the notification you saw? You can still send IM via data however.
[Xperia Z4 Tablet Android Development] tottelicious:
Just installed this on my LTE - so far I'm loving it. Thanks a lot!
[Xperia Z4 Tablet Android Development] jongcruz:
Hi, great looking Rom, What google apps you recommend?
[Xperia Z4 Tablet Android Development] Jadog:
I just checked and Google Hangouts is STILL working fine from my other tablet. And it was working fine before I updated to the LineageOS. Can anybody else who is using this OS please check to see if they can text without getting a SIM Card message?
[Xperia Z4 Tablet Android Development] belrik:
My point is that this feature is no longer supported by Google Hangouts. Try using the regular SMS app. Can't fix a feature that is already deprecated!
[Xperia Z4 Tablet Android Development] jongcruz:
Any help with root please?
[Xperia Z4 Tablet Android Development] belrik:
What are you trying to do? Freeze the camera? Not sure why but error appears to imply that /system is mounted RO instead of RW, just remount with RW.
[Xperia Z4 Tablet Android Development] Jadog:
Can you tell me what the "regular SMS app" is? Android messenger is not supported as it requires a SIM. I was using hangouts because the texting is done using a google number.
[Xperia Z4 Tablet Android Development] belrik:
Sorry, no real idea about Google Voice as that only exists in United States I think. Support shouldn't be limited by the ROM if you are using a data-based service tho, have you tried the regular steps to enable Google Voice in hangouts for messaging? https://support.google.com/hangouts/answer/6023920?co=GENIE.Platform=Android&hl=en
[Xperia Z4 Tablet Android Development] jongcruz:
I already tried re-mounting system and still nothing.
[Xperia Z4 Tablet Android Development] belrik:
What are you trying to achieve? Maybe there is another approach.
[Xperia Z4 Tablet Android Development] jongcruz:
Ok let me explain you, I have root working but not completely for some reason. There is an app (System app mover) that let you convert regular apps to system apps so I can do it to FakeGPS but when I try to make FakeGps a system app I get this error. Another thing is when I try to use (System App freezer) I get the same results.

Thanks!
[Xperia Z4 Tablet Android Development] belrik:
Have you tried using a root file manager or command prompt to move the app? You will see what the actual error is then, just remount RW and try to copy your apk into the apps directory under the system mountpoint.
