...will my saves carry over when I update?
...If you're an Android, be careful to not delete the app, but to update it, or your saves will be deleted too.
If you HAVE to delete the game on Android in order to install/update the game, there is a way to keep your saves. I'm sorry I can't provide good tutorial, because there folder hierarchy is on Android with regards to apps and files is confusing. Basically what I did was use an advanced file explorer (I'm using FX File Explorer for Android) and navigate to:
/storage/emulated/0/Android/data/com.LeStag.NetorasePhone/files
and then archive/zip up all the *.es3 files within, which are the various saves and player profile. Store this archive in a normal user owned location, like your regular download-folder.
After uninstalling the old version and installing the new, you might have to start the new game version at least once to recreate this folder, and then find the above location and unzip the archive back into it.
No guarantees, and on your phone things might be located somewhere completely different, but I have done this successfully once. I do regardless recommend FX File Explorer for anyone to look around your system files. No so-called
root access (which is a higher level normally not given on Android phones) needed to do any of this. I mention it only because if you search you will find other
com.LeStag.NetorasePhone or similarly named folder that you cannot access without
root.
