Sorry to bother - but will repeat my question about NFC (android pay) functionality with this ROM.

Is it normal, that it does not work and crashes while trying to setup "tap to pay" function?
[Xperia Z1 Compact Original Android Development] colaigor:
Yes. Android Pay doesn't work on many many custom roms. Even if you have unlocked bootloader and root on stock rom you still may have problems with it. That's how it is
[Xperia Z1 Compact Original Android Development] Wyzco:
I have installed the latest update however I no longer have write access to my sdcard. Any suggested solution to that's that?
[Xperia Z1 Compact Original Android Development] Guiche38400:
No problem here.

Write access to sdcard OK

- move from internal rom (default filemanager)

- pc to sdcard through usb

Did you try your sdcard on another phone or your computer ?
[Xperia Z1 Compact Original Android Development] Wyzco:
Through the phone connected to the computer the sdcard is writable but in the cell it is only read only
[Xperia Z1 Compact Original Android Development] firestone9x:
This ROM is the best one I've had on my Z1c.

Thanks to those involved in developing it! I am really grateful.

Battery life is now amazing after the last update. All that is left is a GPS fix and then this will be the perfect ROM :)
[Xperia Z1 Compact Original Android Development] Wyzco:
Found the issue, if the file browser by the name of "File" is removed, the sdcard will only mount as read-only.
[Xperia Z1 Compact Original Android Development] Wyzco:
Does anyone know how I could modify the mixer file such that the gain is increased?

Or provide another method to boost the mic gain?

Hi,

I want to try this ROM but I do not want to make errors :)

I have a Z1c 5.1.1 (stock, with flashable-prerooted_D5503_14.6.A.1.236_R2D.zip), rooted with SuperSU 2.82,

recovery Z1C-lockeddualrecovery2.8.26-RELEASE.combined.zip, TA already backuped, xposed-v89-sdk22-arm.

1. What happens with my existing system when I do the required unlocking bootloader?

2. How can i go back to my existing system using TWRP backups?

Thank you for answering my first questions.
[Xperia Z1 Compact Original Android Development] jho55:
Hi,

when you unlock the bootloader your system gets wiped!

For flashing a oreo rom you need the newest TWRP: https://xdaforums.com/showpost.php?p=72496075

Honestly I would first try to get the bootloader unlocked, install lollipop with EMMA tool. Install TWRP, install Magisk/SuperSU.

Do all your current setup again.

Now it is super easy to "backup" your lollipop in TWRP, test another rom, go back with "restore".

Never use Titanium backup for dirty restoring apps.
[Xperia Z1 Compact Original Android Development] tramp20:
Thank you for your help.

It is more complicate for the moment as I thought.

I will wait until the weather will be bad :(

how to enable screen shot/recorder?

Screenshot : Like any android starting with Ice Cream Sandwitch :)

Just press the Volume Down and Power buttons at the same time, hold them for a second, and your phone will take a screenshot

Hi. long time did not put this firmware, I would like to ask about the problems with mobile data(internet) is still present?or fixed
[Xperia Z1 Compact Original Android Development] chbde:
After spending some time with the latest build (2018-07-23), some observations:

- endurance is great! Big improvement over last build, I'd say same or better than stock Lollipop. Fantastic work!

- Camera starts by pressing shutter, but not from locked state (but there's the power button double press that is actually more convenient/ergonomic for me)

- Stock camera lets you set manual ISO, but no effect (uses auto ISO instead). Other cameras like FV-5 and A Better Camera do manage to set the sensitivity correctly. Maybe related to the "iso-values" versus "sony-iso-values" camera parameters?

- Mobile data problem still persists for me.

All in all great ROM, many thanks to all people involved!

Any updates on fixing the GPS connectivity issues?

I would be happy to help contribute with fixing it. It's difficult to navigate around with just mobile network. :(
[Xperia Z1 Compact Original Android Development] Peterthebrecker:
I am currently running AICP - 12.1 - N 7.1 amami on my z1 compact. Is this 8.1 worth a upgrade? The performance on the 7.1 is sometimes not very good. I wonder if it is the rom.
[Xperia Z1 Compact Original Android Development] lukstheboss:
Just flashed the rom and looks flawless.

As everyone already knows, there is an issue with data connection. But I tested two different SIM Card and with my main SIM the data connection works :highfive: and with the other it doesn't. :confused:

I'm just wondering why :confused:

Anyway, great rom and thanks for your amazing work :highfive:
[Xperia Z1 Compact Original Android Development] edwardenglish:
What exactly should one do to help fix the mobile data Problem?

Which logs do the developers need?

I experience the data Problem....
[Xperia Z1 Compact Original Android Development] firestone9x:
Definitely worth the upgrade! Performance and battery life is much better than N 7.1.

The only issue I am experiencing is that GPS doesn't work, google maps has to rely on the mobile network for positioning.
[Xperia Z1 Compact Original Android Development] Peterthebrecker:
Is it possible that the gps will be fixed? As I said I am currently running N 7.1. How can I update to oreo the easiest way? I also want to create a full backup. I have TWPR but it says it won´t back up the internal storage such as photos when I want to create a full backup. Have I done anything wrong? Thank you :o

Edit: I have read that for others the gps seems to work fine. Is it maybejust your phone?
[Xperia Z1 Compact Original Android Development] jho55:
[MENTION=9000640]Peterthebrecker[/MENTION]: First install newest TWRP for Oreo compatibility. TWRP is not back upping internal storage. When you back up and restore the internal store should not get touched. I guess. Just backup photos to a pc or copy them to sd card to be sure.
[Xperia Z1 Compact Original Android Development] firestone9x:
Some users also reported a GPS issue so I doubt it's only my phone since GPS used to work fine on N7.1.

But I guess the only way to find out is to do a clean flash again. Will probably try that sometime this week.

I would recommend doing a manual backup so that there are no conflicts if you intend on flashing the new ROM.
[Xperia Z1 Compact Original Android Development] colarus:
For those fetching GPS issue, try my workaround postet in Jaguar Thread.

Since I took these steps, I did not have any GPS issues with custom Roms. :good:
[Xperia Z1 Compact Original Android Development] sugnuf:
Please install GPS Status (its free) from play store and check if You can get 3d fix with this rom.

Getting location differ from 3d fix.

I got no problem with 3d fix on booth stock 4.4 and 5.1. No problem on LOS7.1.2 too.

But 3d fix dont work on this rom, lock flashes on for few ms, but its not stable.
[Xperia Z1 Compact Original Android Development] tramp20:
Hi,

I need your help again :(

I unlocked the bootloader and flashed Lollipop with EMMA successful.

But flashing of TWRP from your link does not work correctly, the notification LED will not get magenta during booting so I cannot boot into the recovery mode with Vol down.

Flashing seems ok:

c:\>fastboot flash recovery recovery-3.2.2-0.img

target didn't report max-download-size

sending 'recovery' (12324 KB)...

OKAY [ 0.396s]

writing 'recovery'...

OKAY [ 0.821s]

finished. total time: 1.218s

I tried this several times and did even a "fastboot erase recovery" as I had a old TWRP 3.0.2 before.

Edit:

I found the solution here:

https://xdaforums.com/showpost.php?p=75850155&postcount=12

I have to boot into recovery with POWER and Vol down together.
[Xperia Z1 Compact Original Android Development] Peterthebrecker:
I flashed the rom and Gapps mini and everything seems to work fine (including GPS) except the google assistant. I installed the app from the store but when I try to open it nothing happens. My google app is up to date. It worked on N7.1. Has anyone an idea how to fix it?

Edit: It works now but I don't know why.
[Xperia Z1 Compact Original Android Development] Joline:
Hi,

I'm still using stock rom [Lollipop 5.1.1 .236, rooted] and want to upgrade to something newer. What is your recommendation, take AICP 7.1 (issue: development stopped) or AICP 8.1 (issue: beta status)?
[Xperia Z1 Compact Original Android Development] skoda9635:
AICP 7.1:

+ more stable

+everything works

- no more development

- slightly older patches and system itself

AICP 8.1

+ better battery life than on 7.1 or even stock ROM

+ new functions and features not only those that come with 8.1

- some people report mobile data and/or GPS issue

- no performance profiles (yet) - this feature 7.1 has and I really like it because you can adjust performance to be more battery friendly or to go full throttle
[Xperia Z1 Compact Original Android Development] Joline:
So, I'll go for 7.1 for now.
[Xperia Z1 Compact Original Android Development] paroucia:
Hi

i just flashed the rom. my router is dual band and can't find it on this rom. i disabled 5 ghz band and stil can't find wifi. what should i do? i couldn't see any suggestion in the topic!
[Xperia Z1 Compact Original Android Development] 115ek:
There are performance profiles. You'll find the commits here http://gerrit.aicp-rom.com/c/AICP/device_sony_msm8974-common/+/67343 and http://gerrit.aicp-rom.com/c/AICP/device_sony_msm8974-common/+/67346.

They were merged on 28th of july and will be included in the next build. You'll also find them in the experimental build. The ambient display feature for incoming notification is always enabled there.

The data issue just concernes if you don't have LTE because data on 3G isn't working right now. We're still investigating.

Just tested GPS together with Osmand today, no problem for me. But we'll look into it. Please provide logs if you encounter any problems. We can't help otherwise.

This is a known problem an all msm8974 devices from sony (rhine, shinano). As workaround you have to set a fixed 5GHz channel in your router settings. (no auto-channeling)

Hello,

Just tested clean install of AICP-o8.1_amami_20180725_1244 + GPS Test apk (nothing more, even gapps - apk installed via adb). Result the same as in previous builds:no stable 3d fix (only "flashing" for few ms), satellites are visible and signal is ok. Just test Yourself, its free app from GP.
[Xperia Z1 Compact Original Android Development] firestone9x:
I tried colarus post from the Jaguar thread to fix the GPS. But I couldn't get any popup menu from the dialer.

Well, I was going to do a clean flash today but it looks like you already confirmed that you still don't get a 3D fix.

Is it possible to export a log from GPS test so that the developers can see what's happening?
[Xperia Z1 Compact Original Android Development] paroucia:
i changed router settings and it worked.

thanks
[Xperia Z1 Compact Original Android Development] tramp20:
Hi,

I am on the newest TWRP 3.2.2 for the Z1c (with unlocked BL).

I cannot install your AICP-o8.1_amami_20180723_0816.zip because I always get an error: zip file corrupt.

I tried another (older) version , even an AICP-n7.1_amami_20180113_1611_2.zip gives the same error.

I did ofc wipe system, cache etc.

I can make backups of my Lollipop 5.1.1 and restore these without problems.
[Xperia Z1 Compact Original Android Development] A_Laser:
Hi, i am very happy with this 8.1 rom (AICP-o8.1_amami_20180723_0816.zip)

But if I use GPS, there is no stable fix.

The strange thing is that with GPS-apps already the position only with the GPS signal is determined. Even the correct speed is determined.

However, it indicates that no satellite is being used. The status does not remain: no fix

See also the screenshots

[Xperia Z1 Compact Original Android Development] 13brew:
As a man who works on navigation program I can assure you: if your speed and location is determined you may pay no attention to "fix/not fix".

We don't know what accuracy threshold developer set in that setting so you may never get a "fix" option.

GPS can be very inaccurate, especially in buildings. So if, for example, Google Maps can determine your location and build a route - you can relax.

Also I recommend not to set location settings in "GPS only" mode, "High accuracy" is much better.
[Xperia Z1 Compact Original Android Development] tramp20:
I really need help.

I tested TWRP 3.2.1 with he same result: all AICP-files give "corrupt zip file".

I can install Lineage-ROMs, Magisk or SuperSU,GAPPs without problem but no AICP-files :(
[Xperia Z1 Compact Original Android Development] firestone9x:
A proper fix is what shows that you have a stable GPS position. Currently, it acquires a fix for a few milliseconds and then goes away. When using google maps you can see your location pointer jumping all over the map hence google gets confused and starts rerouting at times.

I have used my phone outside when driving on a clear day and positioning is really bad. I experimented with both 'Gps mode' and 'high accuracy' - no difference. I even ensured battery optimization was disabled for both google maps and Gps test but that didn't help either.

Also, GPS test used to show a stable 3D fix on AICP N7.1
[Xperia Z1 Compact Original Android Development] 13brew:
When you open an app - your location may jump for a minute or more, depending on several things. But then it should settle down.

I currently use LineageOS 7.1 and I also tried to get "fix" option - no success.

But in any other navigation apps, and I use a lot of them, my position is determined fast and correct (location setting is in "High accuracy" mode), that's why I recommended to pay no attention to "fix/no fix".

All I want to say is that GPS is a very tender thing and if some people have problems with determining their location - it doesn't necessary say that there's a problem with ROM.

I would gladly install this ROM and test GPS a little, but a had problems with mobile data when I tried to use it (as far as I understood, it works fine only in 4G mode, but where I live it's not stable enough) and I can't afford to lose internet connection:)

UPD:

Just a thought: if this ROM has problems with connecting to mobile networks - it could be a reason why there was no difference for you between "GPS only" and "High accuracy" modes. Without mobile network help (using only GPS) you will always have problems with determining your location on mobile phone, checked on many devices. To get stable position using only GPS you'll have to set up a perfect conditions: outside the city, not moving, lots of satellites. etc.
[Xperia Z1 Compact Original Android Development] firestone9x:
I have used GPS only mode on my previous AICP N7.1 ROM with mobile network turned off. It took a maximum of 20 seconds to get a continuous fix when outdoors.

I am not sure how you are able to get a 'fast and correct' position. Probably you have better triangulation with you mobile networks.

But as far as I know, GPS is essential for an accurate position with speed (not possible with mobile network alone) and if third-party apps like 'GPS test" indicate "no fix". Then there is definitely something wrong with the ROM.
[Xperia Z1 Compact Original Android Development] NhanTruong0911:
A big bug. Sms not working. I can't send any sms.
[Xperia Z1 Compact Original Android Development] esemef:
You should be able to get a fix from 5 satellites while moving as long as it's not built up.

Although if it's randomly losing contact with the satellite then it might not happen.

Saying that randomly losing contact with the satellites is not a problem, isn't entirely accurate but AGPS will help it limb along
[Xperia Z1 Compact Original Android Development] Peterthebrecker:
So there is no fix for the mobile data problem right now? Are there any settings that work?
[Xperia Z1 Compact Original Android Development] 13brew:
I've installed the latest version yesterday.

What can I say - it works really, really good. Very smooth and looks nice. But still no internet in 3G/2G (4G - no problem)

Also I've tried to use navigation to see if there's any problem with determining position (driving a car in city).

In both GPS modes (GPS only and High accuracy) my position was determined without any problem. In GPS only mode it took a little more time but it was expected.

Speed was correct, position didn't jump. And still no "fix".

I don't want to offend anybody, but I really can't see the point with obsession to get "fix" while real navigation programs work good. Reminds obsession with synthetic benchmarks instead of real using of device.

Or I was lucky:)

Anyway, when internet problem will be resolved - it definitely will be one of the best ROM's I've seen.
[Xperia Z1 Compact Original Android Development] sugnuf:
And how long did You test it? In my case gps do not work stable in longer period of usage - fix is not stable, eg Endomondo looses track. I was using GPS Test only to demonstrate problem, not to create benchmarks.....

GPS is problematic in this rom.

Any progress on the 3G mobile data issue? I've changed my provider and the service is 3G only, so I don't have mobile data with this ROM :(...

You were lucky with the GPS. I can't get a position at all unless I enable data. Networks work fine, though :)
[Xperia Z1 Compact Original Android Development] ra9na:
I have an idea on how to tackle the mobile data issue:

I noticed, with the provider supporting LTE I also had 3G mobile data.

Can't we just fake this for the provider without LTE support? I mean just until the root cause is found...

Can anyone else confirm that there is no mobile data issue using 3g or edge when provider only supports LTE?

Hi,

I flashed last build (0825). A clean flash from Sony stock as described on the first page with gapps and Magisk (no additional modules).

My camera is not working anymore (test on stock camera, and open camera) :

I can touch the screen to trigger focus (but the focus doesn't seem to apply)

Touching the on screen capture button or hardware button have no effect.

It's hard to quit the application (needs several press on back button)

AICP extras can't create dmesg and kmesg, only logcat and radiolog are included in the zip file.

Anyone else is having similar problem ? Or I made something wrong during my setup ?
[Xperia Z1 Compact Original Android Development] Brozada:
I think that the issue with GPS is not about getting the fix, but about losing it or reseting continuously. I've seen that device gets position and fix for an instant, and then loses it during most time until next fix. So apparently ther is no fix durong most time, but position gets updated each instant that fix is achieved.
[Xperia Z1 Compact Original Android Development] bedp:
Its really really good

Only few things need improvements, I hope you can fix those bugs.

Thanks a lot for your work

When dirty flashing updates, are there any additional risks in comparison to a clean flashed version?

Currently I have the July version and would like to update to the August version.

I have TWRP 3.1.0 installed.
[Xperia Z1 Compact Original Android Development] 13brew:
Am I going nuts or there was a post from [MENTION=6425591]SpiritCroc[/MENTION] about new version of this ROM with mobile data fix?
[Xperia Z1 Compact Original Android Development] SpiritCroc:
There's always a risk that something has changed in the ROM that causes crashes or other issues when dirty flashing.

I usually do dirty flashes myself, it should be fine as long as you stay on the same Android version and the same ROM.

Just do a backup and if you experience some issues (e.g. some system app crashes), you might need to do a clean flash.

Mobile data works, but not as good as on Nougat.

Especially when you don't have LTE because of your selected preferred network type or other reasons, you have to be lucky to get mobile data. I'm working on that, but don't know whether I'll be able to fix.
[Xperia Z1 Compact Original Android Development] ra9na:
If you find any useful information out of this logs I've attached here.... At least in the modem log I couldn't find anything helpful.

It's really annoying, that mobile data is not working.
[Xperia Z1 Compact Original Android Development] SpiritCroc:
New build (20180908_1022) is up, likely to fix mobile data issues. Please provide feedback! If you still experience issues with mobile network, please provide a radio log (adb logcat -b radio ; or use the inbuilt log creator in AICP Extras if you're rooted)!

I'd also be happy to hear reports of those that could not get any mobile network in the past if it's fixed for them.

Please also report other issues related to this build (apart from bad GPS performance which is a known issue); maybe we can finally start official builds (quick before Oreo builds are stopped in favor of Pie ;P).

camera works great (focus, pictures, hardware button) no lag on focus/capture.

Wifi, Bluetooth, Camera (pictures and video), FM radio, music player, performance profiles, on call proximity sensor/auto screen brightness : OK

Data works on 3G/4G with my 4g provider (Free - France), never had problems with data before.

GPS : Works with known "fix issue"
