[Xiaomi Mi Mix 2 Questions & Answers] nem1so:
I have the same issue with any Android 10 or 9 I tried so far. All network and Wifi works totally fine with LineageOS 15.1, but with 16 or 17.1 I get the same problem you described. Tried Havoc as well, but it's just the same :(

Tried to download Pixel Experience but the download is too slow and fails at some point. As soon as I manage to install it I'll update this post!

I tried to install the carrier service (read somewhere it might help) as well, but it didn't solve the problem either. Changed the APN and the preferred network type (LTE/GSM etc). Nothing.

I also tried it with different GApps (Open Gapps, Mind the GApps, MicroG) or none at all. Same issue.

I ordered a new SIM card which again works fine with android 8.1 (LineageOS 15.1) on the same phone, but not with higher versions of android. As soon as the SIM is removed Wifi works just fine.

Ran out of ideas and will have to switch back to LineageOS 15.1, I guess...

[update] what seems to have done the trick for me was to update the firmware. I just downloaded the most recent one following this post and flashed it using TWRP (v3.3.1-1). No problems with dropping Wifi so far, network connection seems low (2 of 4 bars) but stable.

Im here on the Z1 Forums since 5 years. I dont use the z1 as my daily driver since some years because it was destroyed. But i found some replacement parts on ebay for some €€ and it is so cool, that this phone is still updated. I will check this ROM out. Thanks for the developments and keep up the work! ^^

[Xperia Z1 Android Development] acidrums4:
Dude calm down, this is in Alpha state so it means it is in early stages of development. Dev is working on all things they can and surely he will deliver a quality ROM at the end. You may stick around with 9.0 meanwhile if it's so important to you.
[Xperia Z1 Android Development] KhalidGenius:
Thanks bro you're awesome :highfive:

Already test it. Seem alright overall. Not laggy, very smooth so far.

But, i have question, i installed an app name linkaja, eventhough im not installed any supersu or magisk or any kind of root, why is the app always said im using root?

Maybe it's unrelated, but im curious to know why it happen? My prime suspect is trust app embedded in lineage os, since i installed aicp the app working fine. How can i disabled trust or privacy guard entirely?

MIFARE Classic NFC tag support seems to be broken in these builds :(

lineage-17.1-20200302-UNOFFICIAL-honami.zip

lineage-17.1-20200620-UNOFFICIAL-honami.zip

=> java.lang.NullPointerException when using a MIFARE Classic 1K NFC tag and doing "NfcA.get(tag)"

lineage-16.0-20200620-UNOFFICIAL-honami.zip

=> no problem

Can you point me in the direction of the 16.0/17.1 source code (and build instructions maybe?) that you used, so that I can try to fix this issue?
[Xperia Z1 Android Development] _tim_:
Found it. "Support for third party NFC features and extensions" seems to be the culprit.

https://review.lineageos.org/c/Line...256596/5/core/java/android/nfc/tech/NfcA.java

/** @hide */
public NfcA(Tag tag) throws RemoteException {
super(tag, TagTechnology.NFC_A);
Bundle extras;
mSak = 0;
if(tag.hasTech(TagTechnology.MIFARE_CLASSIC))
{
extras = tag.getTechExtras(TagTechnology.MIFARE_CLASSIC);
mSak = extras.getShort(EXTRA_SAK);
}
extras = tag.getTechExtras(TagTechnology.NFC_A);
mSak |= extras.getShort(EXTRA_SAK);
mAtqa = extras.getByteArray(EXTRA_ATQA);
}

This code assumes that a MIFARE Classic tag always has an "extras" bundle but this is not the case here because the piece of code in NativeNfcTag.java that adds this bundle is (most probably) missing.

https://review.lineageos.org/c/Line.../src/com/android/nfc/dhimpl/NativeNfcTag.java

case TagTechnology.MIFARE_CLASSIC: {
byte[] actBytes = mTechActBytes[i];
if ((actBytes != null) && (actBytes.length > 0)) {
extras.putShort(NfcA.EXTRA_SAK, (short) (actBytes[0] & (short) 0xFF));
} else {
// ignore this case.
}
extras.putByteArray(NfcA.EXTRA_ATQA, mTechPollBytes[i]);
break;
}

help find old firmware

Hello to all.

I can't send private message, besause small my raiting.

Dear NyQuilXT or samebody:

tell me do you still have the old firmware lineage-14.1-20181030-UNOFFICIAL-honami.zip? The link on the mega is not working.

can you upload this firmware to any cloud to download it.
[Xperia Z1 Android Development] KhalidGenius:
To those having trouble with the C6902 modem zip file in LOS17.1, i have modified it by changing the destination flash folder to /system/system instead of previously /system; which is due to the changed folder hierarchy in android 10.

I had some qcril kernel wakelocks issue, that is related to connectivity interface, which prevented the device from going to deep sleep state and thus led to excessive battery drain when the screen is turned off. That got fixed after i modified the modem file and flashed it in LOS17.1 just like it did for me in LOS16 with the original modem file. However, i don't have a sim card inserted in the device so i don't know if the modified C6902 modem zip file will fix sim network connectivity issues. If it works for anyone, please let us know!

I am not a developer, flash this file at your own risk and responsibility.

I will not be held accountable for any damages, complaints or thermonuclear war.

[Xperia Z1 Android Development] Samcode:
Tested and confirmed working properly for the c6902 varient (well done), but sometimes noticed low speed in mobile data connection, i'am not sure if this is due to kernel or to the custom modified c6902 zip.
[Xperia Z1 Android Development] KhalidGenius:
The only modification i did was to change the destination flash folder to /system/system instead of /system. I have no idea why mobile data speeds are low for you. I'd like to help but i'm not a developer, i'm just a regular user :silly: I still hope custom kernels (RZ kernel / XREN kernel) get released for android 10 to give us tons of customization with the ability to undervolt the cpu :fingers-crossed: :fingers-crossed:
[Xperia Z1 Android Development] bot1987:
It is interesting, I don't face any problems with mobile internet. Maybe it depends on career...
[Xperia Z1 Android Development] _tim_:
Thanks. I'm probably not going to try it because I fixed the non-working NFC MIFARE Classic tag issue in the previous build by patching framework.jar and I don't know if this issue is still present in the new build.

I have some feedbacks for the LOS 17.1 for my xperia z1 4gLTE.

First of all, thank you for the all the efforts to bring android 10 for xperia z1.

1. the location/GPS does not work at all.

2.my phone seems to get hot easily.

3. is there anyway to improve the quality of sound by changing the bit Rate output through 3.5mm jack ? I think the soundfx is not good enough.

thank you.

[Xperia Z1 Android Development] EccLipSe:
Just for stock 5.1.1 users;

1)Root your device with NewKingrootV4.50

2) Download TWRP 3.4 from XDA and copy your SDcard, flash with Rashr

3) Load recovery and flash LineageOS 17.1,

4) download gapps arm/10/pico and flash in recovery too.

Finished.
[Xperia Z1 Android Development] lucbertz:
This ROM is awesome; also NFC seems to work, despite the opening post. But then Google Pay does not work because this is identified as an unofficial ROM. The same for other banking apps. I also tried to encrypt the phone, but I lost everything; it went in bootloop after about 10 minutes of elaboration.

These facts and missing MHL support are the only weak points.

Can you tell me how is it better to proceed if I want install and configure MicroG?

Thank you!

Form Aide creates a simple form interface for entering data directly into Google Sheets from your phone. You can setup predefined lists of entries which the app can run through in sequence, turning it into a flexible workout tracking tool.

Features

The templates describing the forms are just data in a sheet - you can create complex forms on your computer with simple data entry on your phone

All data is saved directly to your Sheets

Fields can have default values which can include the last input value

Fields can have lists of allowed values which can include all previously input values

Fields can have additional formatting and sorting options

Sequences let you run through predefined lists of entries e.g. for workout tracking

Links and getting started

Links:

Homepage: https://formaide.cc/

Play: https://play.google.com/store/apps/details?id=com.hippotatimus.formaide

The quickest way to get started is to import an example template (main menu, example templates), for example the "Workout template". As the templates are just data in a sheet, it is fast and easy to make new forms, but it can take a bit of getting used to the format. See the documentation on the homepage for more details on how to make templates and sequences.

Note: the app will request permission to access your contacts - this is required in order to select your Google account, and is not used to access your contacts
