I plan to install CyanogenMod on my Samsung Galaxy Express 2 (Sm-G3815). I have made a backup using Titanium Backup, by choosing the "Backup all user apps + system data" option.
I am not clear on what exactly will be done to my phone, what will be deleted and what left alone. Presumably, the backup I made will allow me to restore installed applications. Assuming that the ROM works as expected (and yes, I am aware that it might not) and everything goes well, will I also be able to restore
- my contacts?
- existing conversations from chat apps like WhatsApp, Telegram and Viber?
- phone call logs?
- sms messages?
Will anything still be there when I reboot into the new ROM or will I have to restore everything (except the data on the external card) from backup?
I have quite a few of my apps on the external SD card (moved there by choosing the "Move to SD card" button on the application manager). As far as I can tell, this move means that some of their data is in the external card and some on the internal storage (as reported by the application manager). Will this cause any issues when I try to restore from backup?
