For what it's worth Apple (through Foxconn) are moving some production of iPhones to India. Samsung smartphones are all Made in Vietnam and have very good build quality.

The reason China has electronics supply chain skills is that for decades they've had massive foreign investment as companies outsource productions and do knowledge transfer through JVs (joint ventures).

For future industries this won't be the case (as its politically unpalatable and China is ageing quickly). The primacy China has in the electronics supply chain is already diminishing.
