Since the latest Feb update I lost my custom dictionar .
Samsung support doesn't know how to get it back after talking to various support people.
Developers or User, please advis .
sorry but this is not a solution
You masking the problem
When you update security patchs or system updates, it should not wipe personal data or custom dictionary.
The dictionary is not a 3rd party app or anything but a native Samsung feature.
Restoring settings does not fix the problem. Please can you escalate
Had to download and use the Google keyboard. Doesn't look good but at least it has predictive text and has started to learn my typing style.
Until the "update" has been rolled back its the only option
