Through a series of event of phone crash and non working OISafe  I discovered this website and read Ulrik Lauren's post and WOW!  It worked for me too. I had almost given up regaining my passwords through OISafe but just couldn't find any other password app that I liked or trusted like OISafe. I am so thankful you posted this help. Before going to the Application Manager and selecting permissions for storage in the OISafe app  I copied the two files  oisafe.csv and oisafe. xml to the root directory of the sdcard and the phone. I also put it in the downloads folder. I deleted the app itself and reinstalled it. The app said it found the import file ( it had done that before but never resulted in anything--- before the remedy of in the application manager-- and Woop  there it was  all of my data. Bottom line this is a great and simple password app and there is nothing else like it out there. I hope they do indeed have an upgrade in the near future as I was told in an email from them.
