Here is a doozy...I have a GALAXY NOTE 2. I held up installing this MIUI for like 3 months. Hoping that there would be improvements to the whole being able to install apps on the SD card and also the launchers allowing widgets without setting them up as system apps and finally google MAPS having latitude working.NOW, I have another doozy, when I install a launcher, the damn MIUI lanucher does not allow me to setup the other launcher as DEFAULT. When I click on the set the other launcher as DEFAULT it just go to the MIUI launcher homescreen. It kicks me out of the other launcher. I used NOVA BTW. It is AMAZING. I am considering leaving MIUI after this fiasco.....
AHAHAHA I had to risk breaking MAH PHONE and just went to TITANIUM LAUNCHER and UNINSTALLED MIHOME and that fixed the problem cause I only have 1 launcher now.
For the dude above me. Go to the permissions icon in the folder in the mihome and then set root permissions there.
This is the problem seen only with MIUI v5. You need to install Latinime.apk from other ROMS or you can install it from the market. I used Touchpal. This is free and awesome with many options. Better than Swype application which is only trial.
