After 1 – 2 weeks waiting , today I got extra 10G google drive space , google is a promised company
I knew that if installed quick office on mobile before Sep.28, 2013 , there is an extra bonus 10G for two years , then I tried to install on Sep.25, but at that time , my mobile does not have google play or google frame , even I rooted it , reinstalled those missing software , I can not login with quickbox .
At last , I decided to replace whole android system for the first time . After a nervous waiting , my mobile started to work again , I installed google play & frame again , it is WORK !
Although the promotion expires in Oct.03,2015 , I will like to use google drive more than dropbox .
