Hi,

normally i read only, but because the community is a bit small here, i got some topics:

1. I've got the problem, that the YouTube App doesn't recognize the Tablet correctly anymore which results in missing resolutions. Every resolution >30p was excluded in my app (if the video only had 1080/60 & 720/60, i was stuck at 480p). If you also facing this: The ro.product.model within the build.prop is different from the stock build.prop. Change it back to "SGP771" and it will work again.

2. The Version 20-08-2016 is totally buggy for me. The device is stuck at "finishing boot" until i hit the power button once. After that i will get a soft reboot and my device boots into homescreen while skipping lock screen but missing navbar/notification and other key features. Tried everything: factory resets, data wipe, reformat to EXT4. Other Version are working well at the first try. Don't know if its a problem on my side. I've not tested the 21-08-2016.

At the end i want to thanky andralex8 very much for this, really boosts a my experience with this device. Keep it up :good:
[Xperia Z4 Tablet Android Development] alex009988:
Try RucurectionRemix, no issues at all. But when I've tried cm some time ago, it works good. No issues you've mentioned.
[Xperia Z4 Tablet Android Development] andralex8:
Thank you for the feedback :).

We have the chance to have a similar platform with the Z5 wich have a bigger community, so I didn't need to start from nothing and could reuse most of work for Z5. And Sony provide great code for AOSP with Jerpele too. So I didn't make so much than adaptations ;).

I build the cyanogenmod and Resurrectionremix versions at the same time, but I only tried the Resurrectionremix version since if one is working the other should be working too because it's compiled with the same device sources. So maybe I made a mistake somewhere, I'll see that.

Edit: Yes, there is a problem with builds of the 20-08 and 21-08, I found what is causing this. I will rebuild that ;)
[Xperia Z4 Tablet Android Development] andralex8:
Fixed version uploaded :).

It's the same without the problem (I deleted some files accidentaly to make the builds 20 an 21-08).
[Xperia Z4 Tablet Android Development] txcLOL:
Cool :). Yesterday i switched over to RR and i really like it. I think will stay there, because this out-of-the-box customization is really a plus for me. But the "problem" with the ro.product.model is the same there, which caused exactly the same problem:

Same problem also exists with the YouTube Gaming App. If you change it, it will work. I am curious if i am the only one with this problem (maybe someone can test it by searching a 60 fps Video within the app) :eek:. But normally ro.product.model is always the Device ID, not the actual "name" (at least for devices i've owned so far). But as i said, not a big deal to change a single value. Everything else is working perfectly.
[Xperia Z4 Tablet Android Development] alex009988:
Strange, I haven't changed build.prop at all and I have xperia z4 tablet in to.product.model. And my YouTube works perfectly, each resolution is available. Definitely , I would tell adralex ,one of the first, about it as I use YouTube every day and a lot. So have no clue how could you have this problem
[Xperia Z4 Tablet Android Development] txcLOL:
1440p is also available for every video for me, even without editing build.prop. But everything with 60p or 60fps is missing. And if a YouTuber is uploading for example only "1080/60p" and no "1080p" separately, i miss this resolutions entirely. Would be strange if i am the only one who is facing this, because it is related to the YT app.
[Xperia Z4 Tablet Android Development] alex009988:
Really strange, video with 1080 and 720p resolutions are also available for me. Upload a screenshot with missing resolutions, fail army, for example.
[Xperia Z4 Tablet Android Development] txcLOL:
I don't want to change it & reboot now just to make a screenshot :D. But i don't talk about "1080p", i talk about "1080p60". I have the feeling that we misunderstand each other :D

Just try this on your Tablet with unmodified build.prop: https://www.youtube.com/watch?v=QzVGf-K2heg

For me there was max. 480p available with "stock" build.prop values. If i edit the build.prop with the values from "Sony's Stock" build.prop, it works fine.
[Xperia Z4 Tablet Android Development] alex009988:
Indeed misunderstood each other:) Right, have the same bug, and editing build.prop cures it.
[Xperia Z4 Tablet Android Development] robdam1001:
Thank you for posting this procedure!
[Xperia Z4 Tablet Android Development] alex009988:
Hi. I don't know what happens but it's already second night when the tablet haven't been charged at all. For sure, it was connected, I saw battery indicator when it was powered off
[Xperia Z4 Tablet Android Development] alex009988:
well, today it was charged. I noticed it charges if you don't press power button to see battery indicator, if you pressed it it doesn't charge..
[Xperia Z4 Tablet Android Development] andralex8:
Hum, I didn't noticed this since I alway let my tablet up, but it agree it could be annoying.

In fact the tablet need to init the kernel even if it's off because of the power driver.

I should focus on init when new kernel will be done.

Currently I'm still working on the new kernel, but I don't have a lot of time since I've got a lot of other things to do (some deadlines soon).

So, the project is a bit slowed, but I'll update the rom soon to have last security patchs, ...
[Xperia Z4 Tablet Android Development] andralex8:
Updated !

No major modification, it's mainly syncing with last cm's sources

Edit : Bluetooth problem corrected :)
[Xperia Z4 Tablet Android Development] andralex8:
Other subject, I rebuilded TWRP and I decided to make an unified version for both karin and karin_windy. The device will think to be karin, it's the same behaviour on TWRP by AndroPlus.

Don't worry, it change nothing when flashing rom to karin_windy since karin_windy roms can be installed on karin device (It wouldn't be possible to install the rom from AndroPlus' TWRP if not).

The new link is here :

https://www.androidfilehost.com/?w=files&flid=114592
[Xperia Z4 Tablet Android Development] robdam1001:
I keep getting "Unfortunately, Bluetooth share has stopped" error after every reboot. Is there anyway to fix this please?
[Xperia Z4 Tablet Android Development] andralex8:
Witch version of the rom are you using? The 20160917 was broken with Bluetooth (I removed it), it should be fixed with 20160918. If you are on this last version, could you provide me with a logcat?

You can also try to remove cache and Dalvik cache.

And if it's also not working, you can reinstall a previous version waiting I solve this problem if it's due to the last version.
[Xperia Z4 Tablet Android Development] belrik:
Finally I had time to setup this ROM and I wanted to say thanks!

Everything seems to work and all apps are working, although the play store didn't detect Netflix or the Hexo theme for CyanogenMod as being available for the tab, both worked when sideloaded. This is on an SGP712.

Also it appears that the ROM is ignoring CM root status, is there a simple method to un-root or use the CM settings to manage?

Small problem as everything working including camera and bluetooth, thanks very much for the hard work.
[Xperia Z4 Tablet Android Development] andralex8:
Thank you for trying!

Did you try to use the root access option in developers options? I don't know if I understand you question correctly, but I just tried on rr an I was able to disable root (I tried and the apps were not able to gain root access by using this option).

Be careful that even if the camera show an image, it's still not properly working, the pictures are blurry with back camera, and the colors on front camera are not corrects. It should be fixed with the new kernel (since there is new binaries for this new kernel, but it's still too unstable, so I prefer to stay temporary like that).

But the remaining should works :).
[Xperia Z4 Tablet Android Development] belrik:
I used the developer options, but with root disabled there, the ROM is detected as a rooted device. Maybe it's my bad memory but I wasn't expecting that to be the case.

Additional point- the hardware keyboard keys all work except the square key, which does nothing (should show the app switcher menu). Seems like CM expects devices to have hardware menu, back, home, power, volume and search buttons but no recent apps button (the 'Buttons' settings area). That's somewhat legacy as Google has been abandoning the use of menu buttons for a while now. On modern devices menu is replaced with recent apps but the hardware settings dialogue doesn't allow us to configure that.

Thanks again for all the work.
[Xperia Z4 Tablet Android Development] Ghostly_Talamaur:
Thanks for your work! Great rom. I hope that Sony release binnary to fix camera issue.

Some problems: I have bluetooth headset and sometimes after voice call i get crash of Bluetooth file transfer. It leads to disconnect headset.

I use cm-13.0-20160918-UNOFFICIAL-karin.zip.

Sorry for my ugly english.
[Xperia Z4 Tablet Android Development] andralex8:
Yes, disable root make the applications unable to use root, but the device is still rooted. The rom is compiled with userbebug, not user option, maybe it make some differences ?

The square button is not working, I already tried to make it functional but no success yet... The buttons options in the settings refer to software buttons, since it's a hardware button the problem is different. The system detect that the button is pressed but don't know what to do with it. For sony it's configured in system files, I extracted them from the stock rom but only past them in cm/rr don't solve the problem.
[Xperia Z4 Tablet Android Development] andralex8:
Thank you for the feedback.

I don't have the possibility to make a voice call and reproduce the problem since I have a wifi only tablet. Did you make a logcat of this issue?

No problem for english, my english is not very good too. The main goal is to be understood, then we do our best to improve the remaining ;).
[Xperia Z4 Tablet Android Development] robdam1001:
I'm on 13.0-20160807. I'll try installing 20160918 to see if that fixes my issue. Thanks.
[Xperia Z4 Tablet Android Development] robdam1001:
0918 fixed the Bluetooth issue, thanks!
[Xperia Z4 Tablet Android Development] Discordian_Nerd:
I would really like to test this ROM for the LTE version of the tablet. Can anyone vouche for the current usability, as I read some people having problems with this version earlier in the thread.

If I wanted to help you, the Dev, with testing the builds, what should I know in advance and how would it work? (sorry for the noob question I have never done this before).
[Xperia Z4 Tablet Android Development] alex009988:
In a word, it's stable and works well. No serious bugs at all. You can fearlessly try it!
[Xperia Z4 Tablet Android Development] jongcruz:
I tried this rom on my LTE version and everything works OK with some minor issues like light not always show when charging, slow charge and low speaker.
[Xperia Z4 Tablet Android Development] alex009988:
The charge seems OK for me, but low speaker seems a little problem. For example, for clash of clans it's OK but for tv it's a bit low, I watch it through the chrome and special app. http://www.1tv.ru/live the volume of sound is a bit low. I don't remember how it was on the stock.
[Xperia Z4 Tablet Android Development] Discordian_Nerd:
Thanks guys! I'm up and running with CM13 now and I'm very satisfied with it!

I can feel it's an Alpha build though, not in any way bad as it's so far a very stable build it seems, but smaller things that need tweaking;

Wi-Fi seems unstable, and I can't use the tethering options or get them to work.

My biggest problem is OTG.. I haven't tried everything i need OTG for yet, but registering a USB stick is broken it seems. The USB drive reacts and shows a little LED light, but the tablet isn't registering it and I can't find the option to detect USB (like you could on stock ROM).

If anyone knows of a fix for the OTG, I would be happy.

Other than that I tip my hat to you dev! Very good work so far :)

Edit: I noticed after i flashed the ROM that my computer won't detect the tablet in fastboot mode anymore. Is this a common issue?
[Xperia Z4 Tablet Android Development] riveria:
You can try this, it worked for me for RRemix:

Once you are connected with fastboot, go and right click your windows menu (assuming you are on win10 or 8) and go to device manager. There should be a device for android or fastboot (can't really remember the exact name), reinstall the device by going to Properties > Driver tab > Update Driver > Browse computer for driver software > Let me pick from a list of device drivers and then select your previous Z4 tablet fastboot.

That should work, at least for me.
[Xperia Z4 Tablet Android Development] alex009988:
Fastboot doesn't relate to the rom in any case. Check your adb drivers (device manager) .
[Xperia Z4 Tablet Android Development] robdam1001:
I'm unable to download Google Play Movies since installing cm13 on my z4. Any fix for this?
[Xperia Z4 Tablet Android Development] siriusvoice:
Audio problem

Hi

I flash androplus kernel ( Z4T_SGP771_AndroPlusKernel_v31.zip

15.9MB Jun 04, 2016 | 07:49AM ) and TWRP for CM( Cyanogenmod unofficial rom for karin (Z4 tablet LTE)) as you recommended, then install Latest Rom ( cm-13.0-20160918-UNOFFICIAL-karin.zip

395.6MB Sep 18, 2016 | 07:58PM) but tablet do not have sound. What am I doing wrong :confused:

Thx
[Xperia Z4 Tablet Android Development] belrik:
Hi guys, having trouble connecting to and pairing the bk50 keyboard. Not getting a pin prompt and not seeing a successful connection created after several attempts. Lots of Bluetooth share error messages... Any tips to resolve? Was working fine for a month previously so unsure what changed, maybe a Bluetooth beacon spammed the service??

Update- yes it appears that bluetooth beacons can cause the bluetooth service to crash so much that keyboard pairing fails all the time. Moving physically away fixed it so not related to the rom, just another issue caused by Android's limited list of entries for known bluetooth mac addresses (the beacons are 'illegal' bluetooth devices which dynamically change mac to ensure they are always discovered as a new device, which fills the table and crashes the service once table is max size).
[Xperia Z4 Tablet Android Development] belrik:
Its mostly working but would it be possible to get regular (if not necessarily frequent) builds to cover the monthly Android security updates?
[Xperia Z4 Tablet Android Development] andralex8:
Thanks for the feedback!

OTG should work. There is no option to enable it like on stock because it's enabled by default. But maybe the tablet don't mount the key? Wich app do you use to browse the files? For me, simply insert an USB key works, I use ES explorer to browse the files.
[Xperia Z4 Tablet Android Development] andralex8:
I don't use Google Play Movies. I seem that other people already had the same problem on other devices, but I only made a quick search on google, so maybe someone already find a solution ? Did you find a solution ?
[Xperia Z4 Tablet Android Development] andralex8:
It seem that you made things correctly. Maybe you can try to wipe data (make a backup if you have datas to save). Or did you change any settings ?
[Xperia Z4 Tablet Android Development] andralex8:
Thank you for the feedback and also for sharing the solution you find :).
[Xperia Z4 Tablet Android Development] robdam1001:
Thanks for your reply. I went back to stock. I can't live without Google play movies. Battery life has drastically improved as well.
[Xperia Z4 Tablet Android Development] andralex8:
Yes, you're right, that what I initialy wanted to do but I forgot to do it for October. The November security update is not already released, so I will wait next week-end to make a new build to have this new mounthly update (I hope it will be release at the begining of the next week, then there is a small delay before included in cm source, so next week-end should be good).

Sorry for the increasing delay between builds, I was very busy (and I will also be very busy for at least till the end of the end of the year).

For other updates, I don't have the time currently to make a deep debug make a more working 1.3.3 kernel. So I let the 1.2.2 kernel for the moment.

Android N for Z4 tablet should be released by Sony by the end of the year, so the new kernel sources will be available and it should be easier to debug this 1.3.3 kernel by comparing the sources with the stock kernel (that what I did for OTG on 1.2.2 for exemple).
[Xperia Z4 Tablet Android Development] andralex8:
Ok, no problem, thank you for the reply ;).
[Xperia Z4 Tablet Android Development] Discordian_Nerd:
I use the app called File Commander. Other OTG functions work, like using a Dualshock 4, mouse or keyboard, weirdly enough..
[Xperia Z4 Tablet Android Development] denk_mal:
you should try a newer version of the AndroPlusKernel. IIRR V38 is the minimum for 6.0.1 and V40 is working like a charm here (with original 6.0.1 from Sony for now)

I'll switch to cy13 later this month.
[Xperia Z4 Tablet Android Development] andralex8:
If other functions works, the usb key should works. Maybe the tablet don't mount the key? Did you try with an other browser ? Or in comand line?
[Xperia Z4 Tablet Android Development] andralex8:
New update :)
[Xperia Z4 Tablet Android Development] Discordian_Nerd:
I tried with the build-in CM file manager, but it does the same thing. I noticed as well that the android system doesn't show the USB key under the storage menu in settings.

Now you mention command line.. How would i do that? I have never fiddled much with the android terminal, if that's what you're referring to :P

Edit: is there a changelog for the recent update? :)
[Xperia Z4 Tablet Android Development] jongcruz:
Update feels really good but speaker volume is still below average.
[Xperia Z4 Tablet Android Development] andralex8:
Try lsusb with and without the usb key plugged to see if the tablet detect the key. Did you try with es explorer too? The key is not shown for me nether in the storage settings, but I can access it, and it's not shown neither with the mount command, strange...

Only security update (update cm source code)
[Xperia Z4 Tablet Android Development] andralex8:
New update !

Same modifications as RR :

- Increase max speaker volume

- Set the minimum brightness lower
[Xperia Z4 Tablet Android Development] aykito:
Hey thank you very much for this mod.

I installed it to my tablet after the latest update to play around:

- Firmware: 32.2.A.5.11

- Androplus kernel v42 (I installed it with your TWRP)

- xposed-v87-sdk23-arm64.zip

I have seen so far two main issues:

- The MAC address is different every time the tablet is booted. This is a problem for the people like me, who filter MAC addresses on the WLAN router.

- The tablet is making a funny short noise more or less every minute, sometimes more often, like a *clack* on the speakers, similar to the default noise when pressing a keyboard key.
[Xperia Z4 Tablet Android Development] belrik:
Any chance of a lineage port for 7.1.1?
[Xperia Z4 Tablet Android Development] andralex8:
Yes, more than that.

I will not tell too much, but I can already tell you that it will be better than the marshmallow roms ;) .

We are working with other developpers wich are doing an incredible work for the Z4/Z5 platform that can be used for the Z4 tablet too.

The rom will be released when fully working (at least beta, no alpha version this time).

That's also the reason why I will not update the marshmallow roms in the futur, the next update should be nougat :).
[Xperia Z4 Tablet Android Development] belrik:
Exciting news, good luck with your efforts!
[Xperia Z4 Tablet Android Development] HotBlack77:
Any News?
[Xperia Z4 Tablet Android Development] andralex8:
We were waiting Sony to re-release nougat to use the new binaries (For my part, I currently use the binaries from marshmallow, but I do not want to make a lot of works if it's to change everything a few weeks later).

Sony only released the new rom today, the kernel source code for this rom is not yet available (it should be when they decided, but they must release it because the Linux kernel is under gpl license).

Then it will depend if they changed a lot of things from the previous rom or not.

I don't always have many time available unfortunately, probably other devs will work faster than me for other Sony devices. But their work is useful for our device too and make things easier for us.
[Xperia Z4 Tablet Android Development] alex009988:
Unfortunately, you are the only one developer who is working for our device. If there were some more developers like on other devices, it would've been much better.
[Xperia Z4 Tablet Android Development] andralex8:
In fact, there is now an other developper that is working on sgp712, and he is doing a very good work (a lot better than me I think). It should speed up things ;). But I don't know if he is on XDA.
[Xperia Z4 Tablet Android Development] alex009988:
In this case, where he is? Can you provide some links of his work for our device?)
[Xperia Z4 Tablet Android Development] andralex8:
He do not provide a rom neither. Every sources will be on github, like always.
[Xperia Z4 Tablet Android Development] belrik:
Is anyone aware of a fix to prevent the bluetooth service stopping at random ('bluetooth share stopped' message) and also to stop the onscreen keyboard showing when the hardware bluetooth keyboard is attached? I can minimise the onscreen keyboard but it pops up on every text entry field.

Thanks
[Xperia Z4 Tablet Android Development] Jigga93:
Little help!

Hello everyone I`m new in rooting part and I need a lot of help in rooting my tablet. If someone could help me by rooting my device with team viewer I`d be so grateful to him or her.

My device is sony z4t sgp771 :)
[Nexus 6 Q&A, Help & Troubleshooting] aroy97:
I honestly made the best decision ever of removing the Facebook app from my phone, with it installed, my phone would drain 20% of battery overnight even with greenify. With it removed, I lost only 5% battery, couldn't be happier.

However, with that said, I use the alternative client Swipe, I really like it for normal browsing, but not the Messenger feature. I still have the FB Messenger app due to its calling,emoji, sticker, etc features, but man is it a resource hog. According to the wake lock detector, it woke my device 58 times.

Do any of you know of any other client alternative to the current messenger app with a better theme than the one in Swipe with the same features as current FB Messenger app. Not too fond of Swipe's messenger as it just loads the mobile site version, its features are limited.

If not, do any of you know how to restrict the app properly to not wake my device so often? Greenify seems to have no effect

Trillian will work with your facebook account. Last time I used it, which was about a year ago, the interface wasn't the best to look at but got the job done. It handles other messaging protocols such as Skype, but doesn't work with Whatsapp (naturally).
[Nexus 6 Q&A, Help & Troubleshooting] misfitpierce:
I was gonna suggest a all in one like trillian and someone on these boards made a facebook messenger and twitter all in one app tho i forget the name. I never go on facebook but I leave it installed but it never takes like any battery, tho I turned off all notifications and turned off chat in the main app and turned off auto load video etc. No issues tho but not many options for third party messenger apps but search forums for the all in one i mentioned.
