Sorry for my poor english..
Yesterday i was update my Wechat to version 5.1, after updated, when i want to open the apps, its always force close. I try several times but still unable open the apps. After uninstall and i want to install again, its prompt out message "Out of space". But my internal memory stil have lot of space to install. I had try to install other apps and have no problem on this. Any idea what happen on this?
