Little F4 5G, here’s how to disassemble and how to repair | Video
Little F4 has recently arrived on the market and, as always, promises great things from the point of view of the quality / price ratio; less than a month after the presentation, the first video teardown arrives thanks to the increasingly prolific PBKReviews. The smartphone gets a Repairability score of 5.5 out of 10 according to the very personal scale of the YouTuber: the judgment is explained by the difficulty in replacing the display, which requires the passage of the flex cable through the central frame. It also doesn’t help that the back cover is made of glass and that it has to be removed, as usual, by applying heat and then using a pick or other thin plastic tool. If nothing else, the edges are not curved, which reduces the risk of breakage.
Once the device is opened, it is noted that a layer of graphite hangs on the first plastic protection of the main board, which helps with the heat dispersion. Other graphite is found for example at the front camera, the speaker at the bottom and on one side of the motherboard where the SoC is located. On the other hand, the motherboard is copper clad and there is heat-conducting paste that improves heat transfer to the chassis. Under the battery there is also a vapor chamber that reaches the border with the motherboard. The battery is relatively easy to remove thanks to the presence of a generously sized tab and a non-exaggerated strength adhesive.
