8: So congratulations, 4G has appeared.

The machine I have at hand is to achieve 4G with the second method, which is to jailbreak and install the free X Snow LET Assistant + Flow Meter.

But now A1528 also has 2 phenomena in 2G and 4G switching, namely:

1: When the call goes down to 4G mode, it will automatically return to 2G, and when the call ends, it will automatically return to 4G (this phenomenon is rare).

2: After the 4G mode, the outgoing call will automatically go to 2G, and it cannot automatically return to 4G after the call ends, and the 4G must be restored with the help of software. Therefore, if you want to talk in 4G mode, you must not lock the glaze, otherwise you will not be able to call back and forth; In 4G mode, it becomes 2G after the call ends, and it cannot automatically return to 4G, and 4G must be restored with the help of software
