Known Issues as of 2017/07/03

This Known Issues List

should prevent one-liner finding reports related to already known issues

should keep later disappointment from end-users of side's optimized LineageOS 14.1 ROM .

defines an everlasting unique identifier for each known issue. Use the identifier for simplified unambiguous communication. Please write e.g. "issue #1" if you want to refer to the battery drain bug

should show possible workarounds, or, even better, should motivate discussions to fix the issue.

should neither let you imply that the issue will be fixed soon, nor that it is fixable at all! It is technically really hard to analyze, find and fix the root cause. Please never ask for an ETA! The community is aware of, and is of cause already unhappy (see e.g. this post) about these known issues.

Known Issues List for stable 4:

Battery drain with Alucard kernel; observed in stable 2; never been an issue of stable 4

??? SD with exFAT not recognized by LineageOS kernel ??? issue reported for stable 2; no reports for stable 4 so far

??? Bluetooth HFP not working ??? issue reported for stable 2; no reports for stable 4 so far

GPS works only moderate; no usage of GLONASS satellites

Issue confirmed by dev: no statement so far

Issue confirmed by test team: no statement so far

Issue confirmed by multiple users: yes see e.g. this post or this post

Root cause: GLONASS intentionally disabled in LOS 14.1 due to too many changes in source code for GPS; see e.g. here

Workaround 1: use e.g. optimized CM13 by side

Discussion: [MENTION=5968293]side[/MENTION] , can you cherry pick working GLONASS code from here? Quote: Now it is fully support GPS, GLONASS and BEIDOU. It is also backward compatible with the AOSP callbacks. Most of the GPS apks (eg. GPS status which was not working in stock MM) would be working now.

Known Issues List for stable 2:

Battery drain with Alucard kernel

Issue confirmed by dev: yes (see this post)

Root cause: profile "default" killed (see this post)

Workaround 1: set "Performance" profile in STweaks (see this post)

Workaround 2: use LineageOS Kernel

Workaround 3: wait for stable 3; [MENTION=5968293]side[/MENTION] expects the issue to be fixed

SD with exFAT not recognized by LineageOS kernel

Issue confirmed by dev: no statement so far

Issue confirmed by test team: no statement so far

Issue confirmed by multiple users: yes (see e.g. this post)

Root cause: unknown; [MENTION=5968293]side[/MENTION] says exFAT should be supported

Workaround 1: convert your exFAT SD to e.g. FAT32

Workaround 2: use Alucard kernel if you want to keep exFAT on your SD

Bluetooth HFP not working

Issue confirmed by dev: no statement so far; [MENTION=5968293]side[/MENTION] hasn't got BT HFP hardware to test this feature

Issue confirmed by test team: no statement so far

Issue confirmed by multiple users: yes (see e.g. this post and this post)

Root cause: quote: "there is something that is not well implemented and fails to connect with some devices" (see this post )

Work around: if you require BT HFP use CM12.1 or TouchWiz ROM (see e.g. this post )

Consider not flashing this ROM in case you can't live with one or more of the listed open issues.

Please report any ideas, how to further analyze or fix the issue. Or please provide better workarounds.

The above list is to my best knowledge. I can neither guarantee it is correct nor it is complete. Please help to improve it.

Every bug is an issue. But there might be issues not caused by bugs (= errors in source code).
