Hey everyone, I'm Leonardo, and in today's video, we will troubleshoot the signal problem on this Galaxy Fold 3. We will carefully dismantle the device, inspecting the antennas and other components for any visible issues. As this is a high-end device, there are numerous antennas to examine. We proceed without a service manual, so we're going in blind.
During the disassembly process, we remove screws, lift various modules, and inspect connectors. Throughout the repair, visual inspection is crucial. As we reassemble the device, we discover the source of the problem - a fractured flex cable. With the help of a microscope, we spot a tiny crack that's impossible to see with the naked eye.
After replacing the damaged flex with a new one from our supplier, we reassemble the device and test it with a SIM card. Although the signal strength is low due to our well-insulated recording studio, after two days of testing, the device has had zero issues.
I'm Leonardo, and that's it for today's video. See you in the next one! Cheers!
