========================================
System Lighting fails on ROG Phone 6. Even done SMNI test and all fails, I haven't done anything to tweak the light. Is it a system error or hardware issue?

Plus when I transfer large files from phone to laptop, it says connection problem, always.

A USB-C 3.1 Gen 2 10Gb/s cable is limited to 1m, the front bays make it difficult to use 5 Gb/s and +, the loss and the total length is the first cause of failure (if we exclude the Windows 11 BUG affecting the transfer of large files)
To try to have less than 0.3 Ohm of loss, keep the passage of the internal cable away from interference and use a short cable (0.3-0.5m) of excellent quality usb-c-usb-c
