FOSS bootloader |
Works |
This device is based on the Snapdragon 410. See the SoC page for common tips, guides and troubleshooting steps |
Note: Even though MSM8916 is capable of aarch64, the firmware of this device was never updated with aarch64 support. Therefore, this device can only boot mainline on armv7 at the moment. |

Installation
lk2nd is a secondary bootloader that provides a standard fastboot interface, which can be used to boot postmarketOS without Android boot
flashed or pmbootstrap flasher flash_kernel
.
- Download lk2nd-msm8916.img from Releases page on Github.
- Boot your phone to bootloader (Odin/Download) mode by holding Volume Down and Home while powering up.
- Follow lk2nd instructions to install lk2nd. Basically flash it to the boot partition (
heimdall flash --BOOT lk2nd-msm8916.img
) - Follow Qualcomm_Snapdragon_410/412_(MSM8916)#Installation to install postmarketOS.
Note: Enter lk2nd fastboot mode by pressing only Volume Down + Power (without Home). Pressing Home additionally will bring you to the Samsung Download mode. |
Touch keys
For configuration of the touch keys, see Tm2-touchkey.
Display brightness
The brightness of the display can't be adjusted, this is not available yet.
Flash LED
Currently WIP. It can be controlled with SG Micro SGM3140 charge pump LED driver[1].
Suspend
Suspend is not yet fully implemented. It's recommended to disable suspend. See Qualcomm_Snapdragon_410/412_(MSM8916)#Suspend.
Display sleep issue in X11
The following issue was solved in postmarketOS "edge" channel when upgrading kernel "linux-postmarketos-qcom-msm8916" to version 6.5.2-r0. In the postmarketOS "stable" channel v23.06 this issue still persists as it uses kernel "linux-postmarketos-qcom-msm8916" version 6.3-r0. |
This device is known to have this common issue where in X11 user interfaces like Xfce4 and MATE, when the screen blacks out after a while of inactivity it can't be woken up anymore. As a workaround, set display sleeping time to "never" in the power management settings. To solve this issue properly, work on the Qualcomm DRM Driver is needed. See the github issue on the our msm8916 kernel fork to learn more.
Mirrored screen on Plasma Mobile and GNOME mobile
On samsung-serranove the display natively shows everything in flipped/mirrored way. To compensate this, the cmdline in /etc/deviceinfo contains video=540x960,reflect_x
. In Plasma Mobile the screen handling is done by KScreen. As KScreen doesn't support flipping/reflecting, everything is shown mirrored. There is currently no solution, work on the panel driver would be needed, see pmaports#1340.
As it turned out, also GNOME mobile is affected by this. While Phosh and GNOME use "mutter" as a Wayland compositor, GNOME mobile uses "mutter-mobile", which is in an experimental state and currently not capable to flip the screen.
Hardware Acceleration in Firefox
As of 04.01.2024 it was observed on phosh that firefox-esr has a broken UI on launch, this has been linked to the hardware acceleration currently tracked on #2332!pmaports and including a hotfix and on https://gitlab.freedesktop.org/mesa/mesa/-/issues/10374.
Official Support Checklist
1. Fix pmaports#1340 (Breaks gnome, gnome-mobile and plasma-mobile usability)
2. Fix pmaports#2332 (To be decided, if it turns out to be a mesa bug then it would have to be fixed otherwise minor issue)
Other components cannot be fixed due to lack of firmware source code and signing keys from Samsung including the limitation to use armv7 instead of aarch64 architecture
