re:
I just found this post over google... so my first post in this forum, but I have the same problem!
I am using default ios notes for years now, my icloud is turned off for notes, my gmail account has a notes folder but I dont use it, and in the settings when I go to notes, it say default account - on my phone. I never touched any settings for notes and I never had any problems!
I have an iphone 5 with ios 8.4
for the past week or so I was using notes every day for a bit, last time jesterday around 7PM, today I open the notes and its empty!!!
i tryed to restart my phone, I also did the power//home button restart, still empty. I tryed to make a new note, works perfecly fine, but other then that... all my past notes are gone!! I have a backup that is few weeks old so I didnt lose too much, but still... how did this happend???
Since jesterday I didnt do ANYTHING with my phone.. no updates, no restarts, no sync or installing any apps... the only thing I did was subscribing to a new podcast.
if somebody finds a solution for this problem, please update this post, I would still love to have m my notes from the past week.
Thanks
