First thank you so much for this great work.

By doing this, a phone from Android 7.1.1 jumps to 11 !

I have the Sony Xperia Z5 Premium Dual E6833.

I've installed this version of Lineage OS 18.1 (20200421)

And found some bugs :

> On the Camera :

- Recording video is not working from back cam

- Super laggy on front camera

- QRCode readers are also laggy on front camera (inbuilt camera app and nextcloud)

This version is not usable as daily driver yet because of the camera issues.

For E6833 users:

For some reason, after restoring my android stock backup, after reboot through the given TWRP the phone gets stuck on SONY white splashscreen. I have to flash via fastboot the original stock system.img + boot.img to make it work again. And that also helps to restore the devide code name from e6883 to e6833. And then can flash with flashtool like old times.

I wish there are much more AOSP builders. And i would like to contribute, but learning from a lot texts is quite hard even if i have the habbit with docs.

Ho! The last update Is corrupted, not install!
[Xperia Z5 Premium Android Development] arpias:
But, THX for your big and last work!
[Xperia Z5 Premium Android Development] arpias:
Hi, i download again the file, file is good but phone go in bootloop, i do a hard reset and try again...
[Xperia Z5 Premium Android Development] arpias:
after hard reset this rom works!
[Xperia Z5 Premium Android Development] Vetkor:
Thanks ! I'm gonna test it this weekend on E6833
[Xperia Z5 Premium Android Development] arpias:
I will test It too when i have time, but my first impression Is good!
[Xperia Z5 Premium Android Development] Vetkor:
Well i just tested it on E6833 , unfortunately the camera app is not launching. (toast message: camera unavailable)

So the app is being closed as soon as clicked/expanded on fullscreen.

Also, i can still take a picture using the message app while sending a picture as message :

> Back camera works, but front camera still laggy and unusuable.

Using probably another app than the main could be a workaround, but still, the front cam is super laggy.

The camera is biggest issue i have currently with Lineage OS. In the previous release of 20210416 the camera app was working, but was just laggy on front cam and back cam was just not working while recording a video.

I'm not a pro yet on android builds, but i feel it is a driver issue than an app misbehaving ?
[Xperia Z5 Premium Android Development] @nyapa:
OK,Thanks!

I give up using SO-03H(NTT Docomo Version Xperia Z5P)

By the way, I tried New Release 20210614Rom

1)Live Display works good

2)Camera app is does not work in video mode

(picture mode is ok)

I installed and tested the "OpenCamera" app, but it hangs in video mode. I think there is something wrong with the OS side

I don't call and message on my smartphone,

so I don't know how that part works

The app I use is working perfectly!

Thank you for your great work!!

during first boot phone will restart and boot to the rcovery
[Xperia Z5 Premium Android Development] Joel16:
Problem is these camera blobs are quite old (Nougat old). I may not have the best or most accurate answer here but what we had to was write our very own camera wrapper around our old camera blobs (libraries) to translate the new camera API to work with the old ones. (open, preview, etc) along with some shims. Basically what I'm saying is, this is a big hack. We obviously cannot do much without the source code and since that is proprietary stuff, we probably will never match camera to stock. The most we can do is get the basic functionality working.
[Xperia Z5 Premium Android Development] arpias:
Hi Joel! For me this rom works good, hope you support for long time, adding more features!
[Xperia Z5 Premium Android Development] Daniel_GB:
Hello and thank you for your great work.

I just want to warn users to be careful regarding how hot the phone gets even with some light usage (e.g., texting on Whatsapp on Mobile data) when using this ROMs. In my case and after using the 17.1 version for about 2 months, the phone screen came off from the top right corner (probably the glue behind LCD panel dried out due to the excessive heat production) causing the proximity sensor to malfunction during calls and hearing voice messages.

I'm now on stock firmware and the phone never heats up like LineageOS ROMs and it also remains pretty cool on light usage, however I need to disassemble the phone to renew the adhesives.
[Xperia Z5 Premium Android Development] Joel16:
That's unfortunate. I'll see if we can tune down the kernel's clocks when I get a chance. The thing is I'm pretty sure its still using the same or similar power profile to stock.
[Xperia Z5 Premium Android Development] Vetkor:
In the past I also tried Lineage OS 14 on the Z5p and it was more stable and everything functional.

At first boot everything was working perfectly. And some weeks later I experienced unstabilities (smooth/lag/ go back to lockscreen) and heat.

So I would confirm the symptom of heating.

I don't know about newer LOS versions.

No Gapp or Root on my Z5p.

I remember that on my old Z3c the root was causing heating issues.
[Xperia Z5 Premium Android Development] alkh301180:
First of all thanks to Joe for making this rom

i wanted to report some bugs:

-microphone not working in apps like telegram

-heating too much. i go over 45 in normal usage

-slightly lag mostly in Qs panel

other functions seems to work just fine(except camera which is a known issue)
[Xperia Z5 Premium Android Development] Vetkor:
WEEK 1:

All right, now i used this LOS 18.1 as a dayly driver.

Of course there are issues to fix BUT we are close to stable.

The biggest priority is probably to fix the camera problem. Cause you cant use the original app. You must install another camera app. I used the app "open camera" on play store.

Major issues:

> Front cam: video recording is super laggy

> Back cam: zoom makes the live view of camera lagging a lot (for picture or video)

> Heat: I dont know if it is because of the current hot summer season that the phone heats easier.

By the way, you will feel more oftenly that the phone is hot in your hands and in your pocket, but compared to stock you can still use all features on the phone without a message "the phone is hot, you cannot use this app".

Minor issues:

> battery drain: I feel like the device lose battery quite faster than before (with a new battery) while using it.

But when you dont use it, you experience the opposite, very less battery draining when not used.

> Little unstabilities when device is hot (notification bar scrolling is sometimes laggy)

> Sometimes i experience (twice today) that the screen brightness goes down to 50% (so the screen look darker from 100%) but the settings shows that you are at 100% and you cannot play with it to refresh.This setting works only under 50%, higher it becomes useless. To fix it, you need to reboot.

> Sometimes you can experience the audio recorder not to work. To fix it, you need to reboot.

> Sometimes you can a toast message "Error I/O.....". To fix it, you need to reboot.

Works well:

Wifi, 4G, Bluetooth, audio jack, SMS, MMS, GPS, fingerprint sensor, proximity sensor.

I havent tested all sensors but i believe they work.

With that build:

For now you should take videos and pictures without zooming with back cam (or it would be laggy)

By the way Zoom featur is like cropping the big picture since it is not a physical lens zoom.

IT DOES everything you need in your day so enjoy and dont be scared to install this rom.

My recommandation:

On front camera: You should stick with only selfies. (video recording is laggy).

On back cam: Never zoom

Globally i'm happy from this build, i feel the purpose of Lineage OS (Privacy) on my 5 yo device !

With the latest Version of android (design, live display and dark mode) benefits.

NO GAPPS AND NO ROOT. Just Lineage OS 18.1

I'm happy that we can live without google nowadays !

I installed yesterday and the hotspot via wifi via usb does not work, and when I turn it on via wifi, it does not turn on without a message, but when I go back to the settings back, it writes that there is an error. I changed the name and password and b password but they don't work. SS (I know the language)
[Xperia Z5 Premium Android Development] Medzik:
I tested NFC enough that I connected it to the headphones and it works, but I did not test it in payments.
[Xperia Z5 Premium Android Development] arpias:
Hi! I wish to know if you have updated the twrp and in what mode, thank you!
[Xperia Z5 Premium Android Development] Medzik:
My Twrp version 3.4.0_9_0
[Xperia Z5 Premium Android Development] arpias:
Don't you update to last?
[Xperia Z5 Premium Android Development] Medzik:
I did not update because I installed it long before 2021 and this version was the latest then, but it may update in some time
[Xperia Z5 Premium Android Development] arpias:
Ok, when you update It please let me know of you can do It and how you update, because i tried in every mode and my phone refused It, i have Always black screen!!!
[Xperia Z5 Premium Android Development] Medzik:
I installed using fastboot and the latest version is working
[Xperia Z5 Premium Android Development] arpias:
My phone don't accept...
[Xperia Z5 Premium Android Development] Medzik:
Got the E6853? Did you check md5 sum?
[Xperia Z5 Premium Android Development] arpias:
Md5 sum Is right, i think the problem Is in the phone!
[Xperia Z5 Premium Android Development] Medzik:
I will tell you that 1 time through fastboot I built twrp it was fine, I flashed and busted again through fastboot and I had a black screen like you, I wanted to turn off the phone with a click on the screen and the power button and volume down and it appeared. And now, with the recovery on, it is fine, it works
[Xperia Z5 Premium Android Development] Medzik:
in short, when the screen is black, click anywhere it's best to click a button if it doesn't work, click the power and volume down button, but not for long so that the recowery does not turn off
[Xperia Z5 Premium Android Development] williamfung:
i am wondering that can you make a button that able to change 1080p and 4k that will much better
[Xperia Z5 Premium Android Development] arpias:

only one simcard works and i dont know how enable second simcard

can u pls help

i know sth missing from etc firmware folder(like modem?) but i dont know what should i do about settings

any help appreciated
[Xperia Z5 Premium Android Development] Pixelado:
Thanks a lot! Gotta try this once I get my Z5P back in working order haha.
[Xperia Z5 Premium Android Development] Vetkor:
Month ONE:

I'm writting this so people can fully try and trust this ROM.

I used it during more than a month.

# NFC WORKS

The only issues are:

1/ Device gets HOT easy (WIFI ?)

2/ Blacklight display flickers (i guess it comes from TWRP)

3/ Camera app doesn't always work like if it cant initialize MediaServer ?.

Also depending on the resolution (5mpx 4:3 front cam works great, all the rest are super laggy).You cannot have 16:9 because too laggy

4/ Camera back camera doesn't perform well expecially on autofocus with some high megapixels.

The video record perview is lagging with 4K recording and 1080p after some time it start to lagg too.

I would say, dont trust your Photophone with this rom yet. The stock OS is the best optimized solution

5/ Wifi tethering doesn't work (hotspot) but the Bluetooth tethering and USB works great.

6/ When the device gets too hot, i dont know if it is the sensor OR a limitation from system. But the screen light goes down directly like 50% BUT it still stays on 100% in the notification bar after scrolling it. The only way to recover it is to restart the device.

Will i continue using this ROM ?

Definitely yes, because in my use case, i only use it as a simple phone, not like most, i dont install heavy apps/games and GAPPS dependend apps.

I still have to update to 20210811 release. I have an old one from my last post a month ago.
[Xperia Z5 Premium Android Development] Pixelado:
This is by design, and it's especially annoying on stock ROMs when it's sunny outside. It's the phone's last ditch effort to avoid frying itself from overheating. You could go ahead and nuke the file which controls thermal management (I don't remember which one, sorry!) but I wouldn't recommend going for this "no brakes" approach, because I've done it before and trust me, this hardware gets VERY HOT.

The "FSC Thermal Engine" magisk module does a great job of keeping heat in check on stock ROMs, even if it means giving up on some performance according to benchmarks, but I'd rather have a functional phone all day long rather than a quick phone with an unusably dim display. I haven't tried it on custom ROMs though.

[Xperia Z5 Premium Android Development] alkh301180:
I flashed the new update. still slightly lag in quick panel while expanding it! but i don't feel too much heat compared to last version. donno if you changed anthing related to that.

screen flickering exists in this rom and also los 17.1, 15.1. and this problem occurred when you fixed live display in all roms and maybe it's also related to twrp

overall thanks for this rom

hope you update los 17.1 cause it's so much smoother than los 18.1:))

Hye Joel,did rom works flawlessly without any problem,but the only problem was im unable to flash vulkan driver, n it caused to phone to get laggy in game performance
[Xperia Z5 Premium Android Development] Meitei:
I installed LineageOS 18.1 with TWRP I think back in August.

And I have the following issue: The stock app for contacts and SMS crashes immediately right after opening. At first, I thought it was because I didn't use a SIM card with my phone... until today... I inserted a SIM card today with the exact same issue. And yes the SIM card was recognized by the phone because I checked mobile data and was able to access the internet via Brave.

I installed two other apps from f-droid and so far they didn't crash, but I haven't tested it with a SIM card yet.

Other issues I had so far:

The right side of the screen isn't visible sometimes with white and black vertical bars when the phone is locked or when I first booted into TWRP.

The colour red is way too dark and more like a wine red, probably even darker.

The headphones aren't recognized.

Would updating to the last version help? Although even if it does it wouldn't explain why I had the issue in the first place.

Edit:

I just tried the two new apps for contacts and texting WITH a SIM card and they crash as well, to it probably was just a coincidence that they didn't when I first started them. Although I have to say the texting app only crashed when I tried sending a text.

After that I got curious and wanted to see what would happen if I would receive a phone call and it was a mess: I couldn't get the call on fullscreen when I tried the screen would flash black and go back to the home screen. And on the phone that called me every option was grey, besides the big red phone button for ending the call.

Kind regards

Meitei
[Xperia Z5 Premium Android Development] cvmg333:
Hello all, big thank you to dev for his work in this rom, your giving new life to z5p, coming from your own lineage 15.1 rom, i enjoy the new android features now, for me the problem with the darker screen brightnees has been fixed, i underclocked the big cores to 1500 following your advice on your latest android 8 rom to keep the device cool and it works fine, after a few days as my daily phone it behaves very well, the glitches well known in the rom as all you know remains, with a few others in my case, Sometimes the camera fc, its rare but some times happen, sometimes when i make a call the other person doesn't hear me well, i have to almost scream at the phone, may be my mic is diyng, when i answer a call everything is ok, rare, dont ask for battery consumption, screen time, or performance cause im dont play games with the phone, and it's battery is old as him. Didn't experience any problem as the post above this explains.

Keep the good work Joel16.

Hi Joel! Lineage 19 when?
[Xperia Z5 Premium Android Development] Meitei:
Lineage 19 would be android 12, right? Given that the lineage-team has only started development very recently I would say it might be at least about a year, if he even works on it.

Did anyone test MHL still work?
[Xperia Z5 Premium Android Development] Meitei:
No I haven't.

I've installed LineageOS again with the September update and used it for almost three days as my daily phone.

Something things I noticed:

+ improved battery compared to google-android*

+ Text, Contact Apps work fine with this build

+ Another App that didn't work on the previous installation works now.

+ Colors look fine on this one, especially the red looks normal again.

+ Calls work fine for the most part**

- Back camera always blurry, even with open camera***

- I still get the black and white lines occasionally when the phone is locked

- Screen flickering when the phone is connected to my PC via USB (I didn't test it during regular charging)

- I always have to make sure that the phone is charged, because once it turns off, because it has no battery, it is a pain to get to turn on again.****

* Keep in mind that the phone is about 6 years old so this is a relative measurement.

It still can get hot rather quickly especially after/while charging

**with one phone call my screen turned black and I couldn't do anything. Now this is something

that happened in the past so this isn't an issue from LineageOS, but maybe something that could

be fixed? Also my headphone jack doesn't work anymore and has to be replaced -> Phone calls on

speaker work fine as well.

***This is something that wasn't the case with the previous installation. But I do take this over the

not working text calling thing any time.

****I have to press the power button + volume down for a while and then see if the phone turns back on again. If it doesn't I have to repeat that process over and over again until it does, all while the phone is charging, which at this point isn't recognized by the phone. To be fair this was only something I tested/ran into with the previous installation and not with the current one. Since I used the phone for a few days like I mentioned, I didn't want to risk it.
[Xperia Z5 Premium Android Development] matbarni:
Unfortunately, without a better kernel and bootloader, most ROMs for this device are not daily driveable.

The screen and camera bugs are harsh.
[Xperia Z5 Premium Android Development] Meitei:
I am rather new at this. What exactly would a kernel and bootloader improve, and how far could one improve this, if at all possible at this point?
