Samsung has just taken the wraps off the Galaxy A57 5G and Galaxy A37 5G, and we already had a look under the hood of one of them. A teardown of the Galaxy A57 by PBKreviews went live hours before the announcement, giving a fairly clear idea of what Samsung has changed this time.
The teardown itself is pretty standard. The back panel comes off with some heat, followed by a bunch of Phillips screws holding the internal frame together. Once that’s out of the way, the layout looks familiar, with the mainboard at the top and the battery taking up most of the space below.
Camera hardware is largely unchanged. You still get a 50MP main sensor with OIS, a 12MP ultrawide, and a 5MP macro, along with a 12MP front camera. The bigger change sits on the mainboard, where Samsung has placed the new Exynos 1680 chip. It’s built on a 4nm process and should handle daily tasks a bit more smoothly, though real-world performance will tell the full story.
One small but meaningful change is the battery setup. The 5,000mAh unit is held in place with pull-tab adhesive, which makes it easier to remove. It’s not something you notice as a user day to day, but it does make repairs less of a headache later on.
There’s also a larger vapor chamber this time. It sits under the battery and looks noticeably bigger than what we’ve seen in earlier models. That should help with heat management, especially during longer gaming sessions or heavy multitasking.
Overall, the inside of the phone feels clean and fairly easy to work with. The teardown gives it a 9 out of 10 for repairability, which is quite good for a modern smartphone.
From the outside, not much has changed. But internally, Samsung seems to have made a few practical improvements that might actually matter over time.
