Answer 2

有,簡單的說,兩台設備中,至少有一個支持OTG.
StackOverFlow上已經有比較好的回答,我引用它的,為了防止鏈接打不開,我把引用內容放在這裡:

It is possible between some phones.

But at least one of them must have OTG support. and you need an OTG
connector.(also a USB cable) Check the following link for detailed
explanation:

I'll be quoting the detailed explanation just in case the link gets
broken:

Yes if u need to transfer data between two phones like GBs of data n u
u have atleast one phone that supports OTG and u been looking for pcuse s to npc-less transfers and EVEN U CAN BORTOW YOUR FRIENDS
BATTERY CHARGE IF YOU ARE RUNNING LOW ON BATTERY!!!!!!

With just an OTG n a USB cable you CAN transfer data and battery

charge between two phones!!

youl need:

A) 2 phones (atleast one with OTG support)

B)OTG connector

C)Usb cable.

D)file explorer like es file explorer

Here on il refer the phone that contains data and charge as "host"

phone n to phone to be transferred as "second" phone.

If your second phone is a xperia device then go to settings ->xperia

connectivity ->usb connectivity

Change the usb connectivity mode from "MTP" to "MSC"..

Steps:

1)Just connect OTG cable to host phone...

2)The second phone connect usb cable.. N the pc usb part.. Which u

connect to pc...connect it to the OTG

REMEMBER 3)In the second phone select ur mass storage option!!

4) use file explorer (I used Es file explorer coz its the best I used)

BINGO.. On host phone u can see the memory card of second phone as

"usbdisk"...plus.. The second phone will charge battery from first

phone...
phone...

Worked on

my xperia Z1 as host and micromax a65 as second phone..

my xperia Z1 as host and micromax a116 as second phone..

my xperia Z1 as host and xperia M as second phone..

my xperia M as host and xperia z1 as second phone..

Well all permutations of these phones..
