[Galaxy Tab S2 Q&A, Help & Troubleshooting] shoalwaters:
My Galaxy Tab S2 is about 4 years old and I use it daily for email checks in the morning and watching reruns of House MD in the evening. System update is set to manual, but I always accept.

Problem: Screen takes significant length of time to repopulate icons after video playback or other tasks. I can actually see each icon appear on the home screen in a sort of ripple effect. This problem became noticeable about two weeks ago. Previously screen refresh was virtually instantaneous. Turning the tablet off for 10 minutes and restarting produced no improvement. There is about 50% available storage on device and card. Any ideas?
[Galaxy Tab S2 Q&A, Help & Troubleshooting] luckeb:
Is battery capacity low compared to when it was new? Might want to replace it. I suspect that cpu gets throttled when battery ages.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] shoalwaters:
Thanks for the response Lukeb.

No, the battery seems about the same as when new. That is to say I had to charge it once per day when new and that is still the case.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] mkdr:
I have the same issue with every Android device I ever owned especially Samsung devices. I think the problem is the "bad" flash memory which wars out over time and becomes slower. Or some secret algorithm in the ROM which slows down your device so you want to buy a new one. I sent my S2 for repair 3 months ago for battery replacement, because it randomly crashes when doing some updates over the Google store when the battery is under 20%. I got it back and it still crashes and is slow. Even with factory reset.
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
My feedback about CR8.0 (weekly build 20200513-0206) with gapps pico, magisk 20.4 and ~75 user apps.

Using TWRP 3.3.1-z3c-20191212-sar from here

Xposed (RiRu 20.2 from magisk repo, EdXposed-YAHFA-v0.4.6.2.4529 from here) works without problems (1st screenshot).

I'm not using internal data encryption because of compatibility problems between ROMs/versions, tired to restore backups each time I flash new ROM.

About 700MB of RAM free just after boot, with stock launcher.

Battery drain fast, but my battery is very old, no complain.

Pros:

+ reliably fast

+ everything works including GPS, BT, calls/data, hotspot and all my apps

+ no problems with audio routing and mic sensitivity

+ camera is ok but I use OpenCamera anyway

Cons/bugs:

- still no 5ghz wifi in Russia (I use my magisk-patch to fix this, may also help with other regions, try if you meet this bug)

- ongoing call can be hanged accidentally by double-tap in any place of turned off display (e.g. by cheek) if tap-to-wake feature is active (here is my workaround using Automate tool, works like a charm). I'm not sure if this bug belongs only to my phone or to any z3c, but it was like forever on any AOSP-based ROM, starting with Android 7.

- broken size for "Aeroplane mode" button/icon in power menu (see 2nd screenshot)

- ringtone sound become a bit quieter after half a second from start of incoming call

- overall loudspeakers volume is not loud enough

Features I'd like to have in this ROM:

1) choose clock position in statusbar (only at left in CR8.0)

2) brightness control by sliding in statusbar without opening it

3) mess up digits on the PIN unlock screen [Carbone Fibers > Buttons > Scramble PIN]

4) unlock instantly when entering last digit without confirmation

5) long press power button to turn on/off torch while display turned off [Carbone Fibers > Buttons > Toggle torch]

6) restrict/disable power menu while phone locked

7) disable notification panel while phone locked

8) set minimal time between notifications on per app basis

9) wake by volume rocker buttons

10) increasing ringing volume

11) debugging over network (settings in devs options, absent in CR)

Most of this stuff available in LOS and AEX roms, but also all (except: 7,10,11, with bugs: 6) can be achieved in CR by using GravityBox xposed module.

Thank you [MENTION=3816568]Myself5[/MENTION] for continue work with our lovely z3c.
[Xperia Z3 Compact Original Android Development] BigBrother84:
Thank you very much for supporting our cute device :)

Did anyone tried edxposed with xprivacylua, Viper4android, Netflix. Do they work?
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
Found a BUG: can't set PIN/pattern to lock screen, getting bootloop after try to set it and reboot.

I use z3c as my daily driver, so I need screen lock, can't use this ROM until fixed. Hope I'm not only one who faces this bug.

Not sure about these apps, but at least GravityBox[Q] and App Locale 2 I can NOT get working on this ROM with EdXposed v0.4.6.0_beta(4471) (YAHFA). As well as on latest february build of LOS 17.1 (but worked fine on january build). May be I should try some newer versions of EdXposed (like ones from "canary" repo or something), but I need screenlock bug fixed first to use this ROM and more of free time. Btw, everything works perfect on LOS16.
[Xperia Z3 Compact Original Android Development] Myself5:
The Setup Wizard is still work in progress, and we just discovered nobody tested it with a SIM so far. We'll take care of it, thanks.

As for your screen lock issue in the other message: are you encrypted by any chance? Also I assume that's not happening on the lineage17.1 builds you mentioned?
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
Tried with and without encryption. With and without Gapps. With and without SIM card. Always same result. Everytrhing fine until you set screen lock PIN either from Setup Wizard or from Security settings. First of, unlock method stays "Swipe" after set PIN. And if you reboot, system's boot to desktop and auto-soft-reboot (without sony logo) after few seconds. And yes, this not happening on LOS17.1

Tried to update from your previous CR7 build (CARBON-CR-7.0-OPAL-UNOFFICIAL-z3c-20190819-2110), using TWRP 3.2.1 from here. Nothing actually got written, so previous installation is fine.
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
Try 3.3.1 from here, it support Android 10 with "system as root". And I'd recommend wipe all except internal storage and perform clean install.
[Xperia Z3 Compact Original Android Development] yxagasasgas:
Doesn't work for me, just blackscreens and reboots. Tried installing it both via TWRP app and fastboot (although strangely enough, even though adb worked, fastboot didn't in Windows, had to boot to Linux), no dice, so went back to my previous TWRP for now.

Would be nice to know what's up with that, but I haven't fiddled with any of this in a long time. Ever since CarbonROM appeared, my Z3C pretty much "just worked" and I never had to do much of any fiddling. :)
[Xperia Z3 Compact Original Android Development] Myself5:
New build uploaded just now has the SetupWizard fixed. The lockscreen bug is getting looked into right now.
[Xperia Z3 Compact Original Android Development] Myself5:
Uploaded a new build. Contains some additional lockscreen clocks but more importantly, the PIN issue is fixed.

f8d3b9c5519b91baba7a917d99b7f09e CARBON-CR-8.0-PAX-UNOFFICIAL-z3c-20200225-1530.zip
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
I can confirm this. Also Google' Setup Wizard passed fine with SIM. Thank you!

What is bother me - the Carbon Fibers menu - as I recall, it usually have much more settings than I can see in this build (see screenshots). This is only to me or some global restriction?

Also camera app not working, this is odd. Though I didn't try it on fresh system (before google's backup restore). Someone please check.
[Xperia Z3 Compact Original Android Development] nikapos:
the camera was not working for me as well, but after some restarts it fixed itself. i dont know how that happened (even tried the xperia camera port from magisc) but i cannot confirm weather that did the trick..
[Xperia Z3 Compact Original Android Development] okij:
You could try if the camera starts working after deleting the folder /data/credmgr with a root file explorer and then rebooting. By doing this, the credmgr folder with the credmanager files are rebuilt by the system, which can help fixing camera issues.
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
Thanks for the tip mate. But it didn't help in this case.

Btw, today I installed (again) latest LOS17, tuned it, rebooted many times, played with microG/magisk/xposed modules - camera worked fine all the time.

Next (steps to reproduce): wiped cache, dalvik, data and system, installed only CR-8.0 (20200225), rebooted to system, skip anything, camera WORKS! Did nothing, just rebooted again, and got "Can't connect to the camera"! I think this is a BUG and hope I'm not the only one who faces it.

I still have a question about Carbon Fibers menu, why it lack items/options? I can't even reposition statusbar clock to right without using "third-party" apps like GravityBox xposed module.

Also, kind of "feature request": time to time I use adb from PC (we all do i think), and I hate to connect cable to micro-USB port, cuz it's weak and can break soon if use freqently. I use magnetic port/cable for charging and "ADB over network" toggle in Developer Options for ADB operations. One of the reasons why I prefer LOS is because of this "must have" thing, they even have tile in QS for toggle it quickly! Can it be added to CR?
[Xperia Z3 Compact Original Android Development] nikapos:
the "cant connect to the camera" returned unexpectedly.. :(
[Xperia Z3 Compact Original Android Development] Myself5:
Hum this new OP looks interesting.

And what is this Twitter Post?

And did someone say May Security Patches?
[Xperia Z3 Compact Original Android Development] BigBrother84:
Thank you for your hard work!

Does encryption work properly?

What works

Viper4android works

Sony Device Dummy works with official Sony apps

Spotify works
[Xperia Z3 Compact Original Android Development] okij:
Great, this looks interesting indeed! :)

Today cr-8.0 also was offered as an OTA update on my Z3c which so far I still have on cr-6.1 (because everything is working well and rock stable on this older version and thankfully you still release monthly security patches for it.)

Have you done some thorough testing of cr-8.0 on the Z3/Z3c devices before making it now official and is everything working (e.g. full camera support and proper in-call audio, which had problems on shinano devices on Android 9 and 10 before)?

If so, I might give it a try this weekend.

Thank you and keep up the great work! :good:
[Xperia Z3 Compact Original Android Development] Reader01:
I tried dirty-flash on my cr-6.1, but without success - I can't boot my phone because it stuck in boot animation.
[Xperia Z3 Compact Original Android Development] Myself5:
There's a chance that due to permission changes introduced in our 9/10 releases you need to clean install. Sorry for that, it's not something I tested given new "revisions" should be clean flashed usually.
[Xperia Z3 Compact Original Android Development] Piospi:
Does anyone know how to remove the search bar at the bottom? I mean the main screen.

Can't install via TWRP

Hi Myself5,

first of all thank you for your work. I am a longtime and satisfied User of cr-6.1!

So now PAX is also available for the z3c. Unfortunately I cannot install it via TWRP. The error message indicates that the build is for the "z3c", but I have the "aries", it says. As far as I remember, there were a Time the z3c named aries. Is it possibly marked in the MAC or something like that? Is there a solution?

Kind regards

clooney
[Xperia Z3 Compact Original Android Development] BardoM:
Thanks for your work, but I'm sorry to say that my experience with this rom for a day hasn't been good, because cr-8.0 has had a very unstable behavior in my z3c, so I've had to come back to cr-6.1, which works like a charm.

My installation steps:

- I wasn't able to install cr-8.0 with the twrp 3.2.3 of my device, so I flashed twrp-3.3.1-0.4-z3c.img from here in FOTAKernel.

- I wiped everything (cache, data, internal storage, system, sd) to get a completely clean installation.

- I installed CARBON-CR-8.0-PAX-WEEKLY-z3c-20200506-2205.zip.

- I installed GApps: open_gapps-arm-10.0-nano-20200507.

- I installed Magisk-v20.4.zip

Everything without error messages.

Then I rebooted, logged in my google account and and started to restore my apps, contacts, call & sms history,... and a bit later of loading the launcher (and while apps were restoring), error messages started to popup ("app X" keeps stopping), where "app X" are: first, play services and play store, but later any other app randomly (especially the first running). After several attempts, that app runs but some times fails after a while and stops again.

If you need from me some kind of more detail report or log file, just tell me. I could re-install cr-8.0 if it was necessary.

I used that twrp first, but it didn't let me install magisk, I got a "Error 1" message, so I tried this other one with success.
[Xperia Z3 Compact Original Android Development] pawloland:
You may like xmlpak magisk module if you use sony device dummy. It allows you to do the same and even more, because it enables you to download almost every vendor locked app from play store. I was also using sony device dummy before, but once I found out xmlpak, I immediately switched to it.
[Xperia Z3 Compact Original Android Development] Myself5:
Due to reports of complications with Google Apps we pulled the PAX builds for Z3 and Z3 Compact. I'm working on a fix and hope to release fixed builds ASAP.

If you had any weird issues, then that's why. Sorry for that.

When those builds get released however, they STILL require a clean install over CR-6.1. Dirty flashing does not work.
[Xperia Z3 Compact Original Android Development] siyman:
Thanks for all your effort! I was wondering where the builds were. Would you be so kind to alert us once they are available again?
[Xperia Z3 Compact Original Android Development] Myself5:
We found and fixed the cause. Builds for the Z3 and Z3 Compact are in the process of getting re-released. Sorry for the issues.
[Xperia Z3 Compact Original Android Development] Flitzepiepe:
Hi Myself5,

after updating to the suggested twrp-3.3.1-0.4-z3c.img I made a clean install of the pulled first version CARBON-CR-8.0-PAX-WEEKLY-z3c-20200506-2205.zip. I observed the same issues as here described. Apps were difficult to install and apps closed immediately after starting them. So the system seemed to be quite instabil. Now I installed the CARBON-CR-8.0-PAX-WEEKLY-z3c-20200510-2130.zip release (did not a clean install) and all the apps, settings and so on are running without any problems (as I tested so far).

Great work and thanks a lot for your effort!
[Xperia Z3 Compact Original Android Development] BardoM:
After a whole day testing the rom CARBON-CR-8.0-PAX-WEEKLY-z3c-20200510-2130.zip, I've had no stability issues :).

Thanks for your work!

[Xperia Z3 Compact Original Android Development] BardoM:
I've just come across a couple of issues related of the SD card:

Default Camera-App doesn't allow me to save photos to SD card.

Vanilla Music doesn't play music files (mp3 files in my test) from SD card.

Does the same thing happen to someone else?
[Xperia Z3 Compact Original Android Development] Flitzepiepe:
Observe the same issue. Photos are not saved to SD-Card.

However, Vanilla Music plays music from SD-Card.
[Xperia Z3 Compact Original Android Development] oimaraf:
You can open the zip file (I use 7-zip), navigate to META-INF\com\google\android\ and open updater-script with a text editor.

In the fist line replace "z3c" with "aries" twice, save and zip.

With this modification the test for the correct device is passed.
[Xperia Z3 Compact Original Android Development] fotofaningo:
Hi Myself5,

first many thanks for your work!

Short feedback:

Clean Installation of ROM (wipe cache, dalvik, data, system) and Gapps (nano) no problems.

Installation Magisk 20.4 failed with "unsupported/Unknown image format"

Pixel Launcher stopps / Quickstep runs

Greetings
[Xperia Z3 Compact Original Android Development] casouzaj:
No problems with Magisk v20.4 here, I'm running the latest build. Which TWRP version have you used? 3.3.1.0-4 here!
[Xperia Z3 Compact Original Android Development] fotofaningo:
I took TWRT 3.3.1.0-4 too. I came from cr 6.1 with TWRP 3.2.3. From that configuration I couldn't flash 3.3.1.0-4. So I first had to flash original .291 firmware, root with .576 Kernel and so on. May be there was gone something wrong. I think I have to try it again.
[Xperia Z3 Compact Original Android Development] casouzaj:
What happened when you tried to install version 3.3.1 over 3.2.3? Which way you used? I use to fastboot mine to the FOTAKernel (case sensitive) partition.
[Xperia Z3 Compact Original Android Development] fotofaningo:
Thankyou for your response!

I tried both ways: fastboot to FOTAKernel and also fastboot to recovery. In both cases the response was "successful", but I can't boot in TWRP. Then I flashed 3.2.3 again, installed cr-8.0 (13-05-2020) - successfull, but when I tried to start the phone it only vibrates one time and nothing else (all variations with only power on, power on with volume-racker). Therefore I had to install the original firmware .291 and the rooting-process. After that I could flash TWRP 3.3.1 and install cr-8.0 with no problems. Only flash of Magisk failed (flash with TWRP and also with Magisk-Manager).
[Xperia Z3 Compact Original Android Development] casouzaj:
TWRP flashed to the FOTAKernel partition can only be accessed by hardware means. Starting with the phone powered off, hold both the power and the volume down buttons. When the phone vibrates (as if it was being turned on), release the power button; when the screen lights up, release the volume down button.
[Xperia Z3 Compact Original Android Development] clooney77:
:good:
[Xperia Z3 Compact Original Android Development] fotofaningo:
Thanks for response! I think the rooting process before failt. I did the whole procedure once more and now it's all ok :highfive:
[Xperia Z3 Compact Original Android Development] kamilchno:
There is possible to get dual channel in sbc codec bluetooth in this rom?
[Xperia Z3 Compact Original Android Development] Italianhanno:
Thank you for this great Work. Love it!

Having trouble viewing .mp4 videos with system viewer (gallery and WhatsApp) VLC is fine.

Missing FM radio. Will it be supported?
[Xperia Z3 Compact Original Android Development] oimaraf:
Cr-8.0 or Android 10 must have drilled some holes into the battery of my phone.

Lost 30% of capacity in 8 hrs over night only in standby. Didn't open any app and not only one background task was running.
[Xperia Z3 Compact Original Android Development] e719e:
I also had this situation. The upgrade from 6.1 to 8.0 ended with an unusable result, so I installed it on a cleaned (all wiped and data formated) phone. Everything started working, but the battery quickly drained even in power save mode. I tried to disable many options, but it didn't work. Then I flashed the newer twrp-3.3.1-z3c-20191212-sar.img (was 3.3.0 and not "sar") and tried to install LineageOS 17.1 for z3c. Everything worked and the battery discharged that with CarbonROM cr-6.1 [z3c] - slow. Then I installed CarbonROM 8.0 on a cleaned (all wiped and data formated) phone cr-8.0 [z3c] and everything is beautiful for me. Discharge 2 percent in three hours a night.

After a few days........

The quick battery discharge is back and I can't resolve it. I returned to CB6.1
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
Hello guys I wrote my full review/experience using this ROM at post #2, if anyone interested. Most of bugs seems fixed since I try it first time (still lack of some cool features out of the box though, comparing to LOS). Big thanks to [MENTION=3816568]Myself5[/MENTION] !
[Xperia Z3 Compact Original Android Development] pawloland:
Those two last bugs that you mentioned were bugs in LOS 16 and maybe 17 made by [MENTION=8746471]NeoArian[/MENTION]. I am not github guy, so I don't know what exact commit it was, but it was bug for ages and there were a lot of changes in code regarding audio stuff until it was finally fixed.

Also the fourth feature that you would like to have, was removed from AOSP and is missing since Android Nougat times, because of security concerns. It was/is dangerous because when user have - lets say 4 digit pin - and passes to many digits while unlocking the phone, it stops accepting them right after the 4th digit is passed. This behavior gives information about pin length to potential thief. It narrows down the range of possible pin codes combinations which unlock device.
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
Hmm... I was on LOS 17.1 (prior to CR 8.0), and sound volume (ringtone and alarm) felt a bit louder there. May be it's just my personal impression, not sure... I will not backup/restore just to test this.

But with GravityBox it not stops accepting digits after last one (if some of entered digits wrong) - I just checked. So thief will not know the lenght. AOSP devs could have fix it instead of removing.
[Xperia Z3 Compact Original Android Development] Myself5:
That is by far a lot worse. Without the system going into a "this is wrong" state theres never a situation in which to reach "too many false attempts" allowing for easy bruteforcing of the PIN without any penalty.

As for your feature requests: both, PIN scrambling as well as longpressing the powerbutton for the torch already exist.
[Xperia Z3 Compact Original Android Development] Hooin Kyoma:
Well, I just entered wrong PIN (random digits and press ENTER) 4 times and got penalty (see screenshot). It looks like GravityBox somehow ignore this "penalty" ONLY if you enter PIN without enter (confirmation button). For successfull bruteforcing thief should know that I could using this feature in my phone (and this is possible only if thief is friend of mine, who I told about this feature, or he is also reading this thread and has physical access to my phone, or he's goddamn genius... looks like almost impossible situations :)) And in my case (Im not using encryption atm) genius-thief can easily access my data without bruteforcing anything :D

Oh, yep, sorry my fault. Updated my review.

Btw, can anyone confirm this bug in latest CR8 or it's only to me: ringtone sound in Settings is louder than same ringtone when I get incoming call?
