What's the difference between TELEPHONY_SERVICE1 and TELEPHONY_SERVICE
1 answer
I don't have the source, but I really believe it is being used to extract the TelephonyManager in Dual-Sim phones for another card.
Aside from the fact that it was obvious from the name, Google is also throwing a lot of Chinese results - coincidentally, Dual Sim phones are very popular in China.
I hope someone can support it with a trusted source or test it on a Dual Sim phone.
