Samsung Galaxy A70 Custom Rom (SM-A705F)

It turns out that the custom ROM for Samsung Galaxy A70 is quite difficult to find and not many developers, the thread on XDA is not that crowded.

Samsung Galaxy A70 is a 6.7″ phone with a 1080x2400p display completed with Snapdragon 675 chipset and paired with 6/8GB of RAM and 128GB of storage. The main camera is 32+8+5MP and the selfie camera is 32MP. The battery has 4500mAh capacity. You can check the detail specification from GSM Arena. I using SM-A705F type in XID area code.

Samsung Galaxy A70 released on May 01, 2019, has been on the market for almost 2 years. But if you check on XDA, there are only a few developers who develop custom rom, there may be many obstacles to face. Here are some custom rom that can be found, One UI OS based and AOSP based. If something has been missed or requires an update, please fill it in the comments below.

• LineageOS 16.0 (Android 9)
• LineageOS 17.1 (Android 10)
• LineageOS 18.1 (Android 11)
• Havoc-OS 2.9 (Android 9)
• Havoc-OS 3.1 (Android 10)
• crDroidAndroid 6.13 (Android 10)

• Infinity OS v2.0 (One UI 2.5)
• AkimiOS V2 (One UI 2.5) Discontinued
• Snake OS (One UI 2.5)

If you are interested in trying to apply custom rom, there are few things that must be considered based on my experience

• Knox not functioning properly, even though back to using the official rom
• You must understand the steps well before starting
• You need to make backup of your data
• You need to unlock bootloader, and in this step the internal memory need to wipe all
• Just prepare the Official Rom to restore the condition if something happens
• I don’t know what’s wrong, TWRP Recovery 3.3.1 work smooth compared to others

One UI OS based or AOSP based

So far I have never tried AOSP based custom rom on my Samsung Galaxy A70, it seems there is still a pretty dominant bug, because my cellphone is used for daily use and there is no backup. I have tried 2 One UI OS based custom rom that are Infinity OS v1 and SnakeOS (initial release), and SnakeOS looks better.
