Some cell phone counters have a box/tool to do this for you. Have them try it.
I moved 835 contacts from an old Nokia to a Lenovo A269 (gingerbread 2.3), but only names and phone numbers are shown properly, the "Notes" fields were copied in gibberish (ie. birthdays, notes etc on Nokias) even though no special characters are included.
First I used this app, Import Contacts, https://play.google.com/store/apps/details?id=org.waxworlds.edam.importcontacts&hl=en
It didn't work.
Then I tried copying contacts from SD card.
My contacts were saved in individual vcf files, not one inclusive one, could that be an issue?
Or is this Notes field a known problem with Nokia?
I use the Notes field extensively. Given the number of contacts, I want to avoid having to manually enter "notes".
