Portable HDD Support via USB ports is not possible even though micromax has mentioned that support is possible, I have contacted Micromax customer care twice but they said that I can connect but Micromax is not committing anything even they have mentioned online on their portal.
Screen sometimes shows while vertical lines at left or right end.
Application download from Microsoft store is only download in the internal memory you can not change the path to the external micro sd card. It means if you would like to upgrade your windows 10, you have to remove all the applications for the upgrade. After installation of one game from the store which is about 1.9 GB system is hanging too much. Customer service rating 2 out of 5.
