A budget A-Series Android smartphone manufactured by Samsung in Late 2019 running on the msm8953 platform (with Snapdragon 450 CPU, Adreno 506 GPU), and three variants (3/32GB, 4/64GB, 2/32GB) for RAM/Storage, and 3 models depending on your region (SM-A207F, SM-A207M, SM-A2070).

1. All of the following information applies only to devices with the Android 11 firmware. So update yours to Android 11 if needed.
2. Unlock the bootloader (This will wipe all data so make sure to backup first)
   • Make sure the phone is connected to internet
   • Enable developer options
   • In developer options, enable OEM unlocking
   • Boot into download mode
     • With the phone off, hold both volume keys and plug your device to a computer. Release the buttons once you see a blue screen
   • Hold Volume Up for about 7 seconds then let go of it
   • Press volume up once to confirm bootloader unlocking process (This will erase all the data in the phone)
3. Download a GSI, make sure it's ARM64 A/B. Its file extension should be ".img" if its a zip, tar or xz (whatever) it probably needs to be extracted. Try the vndklite/non-vndklite variant. If one doesn't boot, try the other one.
4. Download an empty vbmeta (to disable secure boot verification)
5. Boot into recovery mode (adb reboot recovery or turn on the phone holding the volume up & power key)
6. Press factory reset, erase cache partition and then Reboot to bootloader (to boot into download mode).
7. With the device in download mode, flash the GSI and VBMETA using your preferred method:
   • Heimdall (Windows/Linux): Run heimdall flash --SYSTEM <gsi.img> --VBMETA <vbmeta.img>. Note that Heimdall on Windows might require you to install some drivers.
   • Odin (Windows): Rename the GSI to system.img.ext4, rename the VBMETA image to vbmeta.img, add both to a TAR file & flash it in the AP slot. Note that some versions of Odin might not work properly.

The bootloader of this device has a bug where it refuses to load modified boot or recovery partitions. If you ever plan on modifying them (for example to install Magisk or TWRP), you need to "fix" the boot/recovery image first. More information here

Component	Comment
Camera	Works (but auxiliary cameras aren't exposed so apps can't use them)[7]
Speaker / Mic	Works
Bluetooth	Works (and BT Audio works too)[1]
Wi-Fi	Works (and Hotspot works too)

SD Card	Works
MTP (Connection to PC via Cable) and other connection modes	Only options File Transfer and PTP don't work, USB Tethering and MIDI work properly[2]
ADB (via Wi-Fi or USB)	Works
Other feature	To be tested

[1]-Bluetooth file transfer works ONLY if you are sending or receiving files from a device with bluetooth version newer than 2.0, and connecting to more than one device at once can cause bluetooth to become buggy, the only solution to this issue is to flash the custom kernel and use a GSI that reports the correct device model (SM-A207F) or modify props in the file build.prop to reflect the correct device model.

[2]-MTP works on a modified kernel with this patch and this patch and a magisk module that reverts this patch

[3]-In-call audio functionality depends on the GSI, the one linked below is tested to have call audio working just fine.

[3]-You may need to enable the option to automatically restart RIL in Phh-treble settings if the in-call Audio is broken after a very long system uptime, Also, PhhTreble GSIs have a bug (specific to Samsung devices) where the incall audio for SIM 2 isn't working, and if you are using Dual SIMs, you will not be able to hear any audio in calls made by SIM 2, this issue can be fixed by just flashing this Magisk module.

[3]-For Mobile Data, This phone (or the GSI) currently has a bug when using 4G (LTE) as the connection mode where it fails to access internet and causes the phone to excessively overheat, this can be fixed by enabling the option to restart qcrild on boot in PhhTreble Settings app.

[4]-The functionality of Fast Charging while booted into the system is dependent upon the GSI you are running, but you can try to flash the custom kernel, it may fix your problem.

[5]-Some GSIs have buggy or broken Offline Charging, but that's pretty rare as most GSIs I have tested have Offline Charging working just fine.

[6]-Screen Mirroring (Cast) feature can be enabled on AOSP-based GSIs by setting the prop persist.debug.wfd.enable=1 in the build.prop file, flashing this Magisk module, Enabling the Xposed module "WiFi P2P Fixes for A20s" and setting its scope to "System Framework".

[7]-Auxiliary cameras are hidden to the Android's Camera HAL by default on non-stock firmware, this is the default behavior of stock vendor, You need to set property vendor.gsi.test to 0 to force the vendor to expose them.

[8]-Wi-Fi Direct can be fixed by installing this Magisk module then Enabling the Xposed module "WiFi P2P Fixes for A20s" and setting its scope to "System Framework".

Tested By: InsertX2k - On SM-A207F/DS(EGY), Build Number - A207FXXS5CWF1

GSI Tested: Pixel Experience Plus 2025-06-22 Android 13 (arm64 A/B, Slim, No SuperUser, and with Gapps installed)

Note: Android 14 QPR2 and QPR3 GSIs require a permissive kernel, OR Modifying the Platform SEPolicy of the GSI image to be able to boot it with the enforcing modified kernel image, click here for more information.

[1]-Fixes to these issues and other notes are available on the Android 13 notes. [2]-Fast Charging on most GSIs require the SELinux mode of the kernel to be Permissive to work properly OR You can flash this magisk module that fixes the SELinux denials responsible for this issue.

Pretty much all notes of Android 13 apply to Android 14 too.
