G610F custom ROMs often use CPU governors not optimized for Snapdragon 625, causing excessive power draw.

Now, when you go to Settings > About Phone, you will see SM-G610F.

On paper, the SM-G6100 (China spec) and the SM-G610F (Global spec) are nearly identical twins. Both utilize the Qualcomm Snapdragon 625 processor, both feature 3GB of RAM, and both sport the sturdy metal unibody design that defined the J7 Prime era.

However, the user experience is vastly different.

The G6100, designed specifically for the Chinese market, comes saddled with limitations that frustrate international users:

The conversion to G610F promises a "cleaner" Android experience, better Samsung Pay integration (depending on region), and access to the global support ecosystem.

Flashing a G610F modem file onto G6100 will almost certainly wipe your EFS partition. Without a backup, you lose cellular connectivity permanently.
