At first you have to download Font Zoomer and Bangla Font both. Then have to install Font Zoomer. You will find a folder in File Manager named "FontZoomer". Move that Bangla Font to this folder and open Font Zoomer app.
Go "Show Font List" option and select that bangla font and apply it and exit from that app. Now you will able to see bangla, just need to restart your phone.
You have to apply this process everytime when you restart or off-on your phone. Thank you.
