Probably you have a phone operating system without JAVA. It is possible because people can change I9/I9+++ operating system by another. One possible to download in net is without JAVA, so there are no chineese games and dialers. But in factory operating system JAVA works and there is JAVA icon. It gets .jar apps installation and some JAVA regulations. One way to return JAVA in phone is to change operating system using MTK tools and special cable (not that used to normal downloading to phone). It is difficult procedure not quite described in net. But... I9/I9+++ has slow , about 50MHz processor and only simple JAVA applications works well. Do not expect to GAMELOFT games work slightly. For instance java pdfviewer load one page about 2-5 minutes.
