Frequently Asked Questions

I've been asked to provide logcat, how do I do that?

You can either root and use an app like MatLog, or if boot logcat is required? You will need adb logcat from a PC. Here's a simple guide from the LineageOS Wiki https://wiki.lineageos.org/logcat.html

My lockscreen crashes after reboot, what should I do to fix it?

I don't see an option for call recording, what's going on?

Only the stock dialer app supports it. If you install a Gapps package that overwrites the stock dialer app? It won't have call recording as well. Only the included dialer app of LineageOS is compatible to call recording since it needs to be a ROM implementation and I haven't seen a Play store app that adds support for custom ROM call recording. Please also note that call recording is blocked for countries and carriers that have laws against any form of call recording.

What is Power-off Alarm?

This feature allows you to set an alarm clock with the stock clock app included with LineageOS and then turn off the phone, and it will boot up a minute before the designated alarm time and then properly alarm. It works with the device either powered off and also offline charging. :)

Using a clock app from OpenGapps Stock or from the Play store is not compatible to custom ROM implementations of power-off alarm... So consider this your heads up if you didn't know that already... As I am not responsible for anyone being late for their wedding/work/school/vacation if you tried a non-stock clock app with your LeEco msm8996 device powered off. :silly:

What apps are recommended with the Open Source ConsumerIR?

(WIP! I try to include it only on unofficial builds until selinux neverallow policy compatibility is fixed... Which tbh is beyond my current skill)

Zaza Remote and Mi Remote work great. Smart Remote for Sharp TV also works. I'd recommend avoiding Peel Universal Smart Remote as it hijacks the lockscreen with ads...

Pls sir, I can't connect to my network or IMS/VoLTE doesn't work! What can I try?

Please look below at the "APNS Update from Google" section and try that. I can't offer much else for help sorry as I have zero experience with IMS/VoLTE as Canada blacklists BYOD from that feature... Otherwise if you need extra help? Hopefully someone else in the x2 community can give you advice.

What is the difference between the official LineageOS builds and unofficial?

Unofficial test builds are builds I put out to test changes before I push them to the Official builds... So please stick with Official builds if you want to play it safe... But if you wish to help test and provide feedback on changes before they go official? Unofficial test builds are the best way to do so.

Where is the QuickCharge toggle?

Settings > System > Advanced > LeEco Settings

The rear facing camera won't focus, what should I try?

Please go into Settings > System > Advanced > LeEco Settings, and then enable the focus fix. You may need to restart any open camera app or potentially reboot the system in order for the focus fix values to work.... If that doesn't resolve it? Please try EUI ROM... If it still won't focus? I'm sorry, but your hardware camera actuator is defective and you either need to try the Le Max 2 rear camera magnet trick (please Google it) or replace the rear camera hardware.

Why is our widevine level only L3?

Unfortunately Widevine L1 failed to work correctly on X2 and zl1/0... It would report we have L1 hardware support but vp9.secure and avc.secure codecs were failing to render, thus apps that used L1 like Amazon Prime would error out and revert to L3 and worst case scenario apps like Vudu would crash.

I haven't seen any fixes for those codec issues, so I gave up on it as L3 works fine.

Also, Netflix HD will never work on LeEco devices as they never got them "Netflix certified" which sounds like a money-grab move since L1 is all they should need. For example, Asus Zenfone 5z is L1 certified but not "Netflix certified" just like us and they don't get the option to stream in HD.

This explains it a lot better

My device doesn't show any apps in the Play Store what should I do?

exfat does not work on LineageOS, what is up with that?

LeEco Le Max 2 does not ship with exfat licensing so we are not allowed to incorporate it in LineageOS Le Max 2 builds. This was tested by both CrisBalGreece and I. If by chance there is an OFFICIAL EUI ROM build that includes exfat? Please let me know so I can test it as well... Here is the LineageOS device charter requirements on exfat

KNOWN BUGS for x2 and max_plus

Updating using the built in LineageOS updater when encrypted causes Google Play Services to crash repeatedly (updating works fine if you have Lineage Recovery installed though. Manually installing newer builds of LineageOS via TWRP also works.)

Microphone and button on 3.5mm headsets using the 3.5mm to Type-C adaptor only works with reversed orientation (IE, official LeEco adaptor with the logo facing downwards)

Dual-role USB does not work (our Type-C port can't detect if it should offer the option to host data transfer, charge the other device, or charge while using Aux out).

Taking a photo during 4K UHD video recording produces a photo with green static instead of a photo. This bug only happens in Snap camera... Google Camera Mod and Open Camera (with Camera API v2 enabled) produces pictures without issue.

Screen on Time is usually only around four to five hours (VERY hard to diagnose battery drain issues... Any logcat with references to battery drain or kernel wakelocks will help resolve this)

CDLA cell calling has crackling/popping sounds

Infinity focus not working (for panoramas, AR and some QR code scanners. Infinity focus also doesn't work in EUI ROM hmm... oddly enough some imx230_lg modules infinity focus can work if you dont need focus fix... so I blame LeEco for the messed up camera haxxs they did since s2 and zl1 have the same issues.)

KNOWN BUGS for max_plus

ES9018 Hi-Fi Audio DAC for 3.5mm headsets to Type-C adaptors does not work (this is the bug that is preventing official unified builds of LineageOS of x2 and max_plus...)

Fingerprint does not work when device is asleep (this is due to the ancient device firmware on max_plus being officially stuck on 13s... there is a pseudo 466d modem firmware fix attempt I made but have not received feedback on yet)

Boot animation does not work (this is due to a fix for screen tearing... maybe one day I'll figure out a fix for boot animation to work with the screen tearing fix)

When launching a camera app, viewfinder goes green for a second and then works normally

After using USB port with Type-C headset or OTG with a flash drive, the device cannot charge until a reboot is performed (known bug even on EUI ROM)

APNs Update from Google

Latest update: 05-06-2019 (May 6, 2019)

This is an optional update if the current APN settings from LineageOS might not be up to date for your carrier and you need newer ones. This is the official APNs list from Google.

After flashing it? Please reboot to system and then go into Settings > Network & Internet > Mobile Internet > Advanced > Access Point Names > "..." menu button > reset to default.

https://sourceforge.net/projects/lineageos-for-x2/files/Mods and Tweaks/APNs Update from Google/

The official Google source git for this file can be found here:

https://android.googlesource.com/device/sample/+/refs/heads/master/etc/apns-full-conf.xml

Please note! This APNs list WILL get overwritten by the ROM on any ROM update and will need to be reinstalled.
