I have an LG G2 Smartphone and after receiving firmware update, my calendar app cannot start, I have tried disabling Sync with other apps , but each time I try to start the App it will crash immediately without error log, what could be the problem? How do I get my calendar app working?
It might be a problem with the update, there are probably two reasons for your problem:
1) Either your update is not done properly, there is some error in the updating process.
2) Or the update you have taken is not genuine one.
You must restore the phone to the previous version, then take an update properly from a genuine place, because with a genuine update all the internal applications also get updated and does not cause any trouble.
