iPhone 6s bluetooth, wifi, cellular weak
On my iPhone 6s the power of the four signals wifi, gps, bluetooth and cellular is weak.
The wifi only works with the 5ghz band, the GPS is not accurate and the bluetooth is very weak. The gsm signal is slightly weaker.
I replaced the connector at the top left, but with no results.
I do not think it is a chip problem, someone has happened and found a solution?
Ps Sorry for my english.
Is this a good question?
