When you try to edit the note field in any of these faulty phone models (and makes), the data gets truncated (or removed) beyond 1000 characters (and in some cases less characters) automatically soon after you save.
These are the Android phone devices whose buggy Google contacts notes behavior has been so far found, hence avoid buying them;
- Samsung S4 (Android 4.3) it chops a note data at 1001 character limit.
- iPhone 3GS (on iOS 6.1.3) truncates at 32,777 chrs (so pretty big notes!)
- Samsung Galaxy Note 10.1 (GT-N8020 – Android 4.1.1) chops at about 1,000chrs, even if just adding a phone number to the contact so not even editing the notes field
- HTC One X (4.2.2) at 5,122 chrs (when editing any part of the contact)
- Oppo A1k CPH1923 (Android 9 Kernel4.9.117 and ColorOS 6.0.1) chops the contact field data at 1001 character limit.
On the Truncating Notes Issue, these phone chop a note but only if edited, at 1001 characters or less limits. However unlike others, it seems to only truncate the note if you actually edit the note field, so adding a phone number or removing one, leaves the note field intact.
It can be a nightmare if you lose your precious notes data in a particular contact field due to this Android bug. Your best bet is to always back up the original google contacts via web on a desktop or a laptop/notebook by exporting them from;
The same bug in the mobile phone firmware (to expand the contact notes data field) should be reported to the respective phone manufacturer.
