sendKeys wrong keys

Hey,

I’m running Appium 1.12.0, trying to fill a field with the sendKeys() function of the driver on Nexus 5X device running Android 8.1.0.
The page represents an address, all the fields(address, city, state etc.) filled correctly, but when it gets to the Zipcode(last field), Appium fills wrong text(i.e instead of “A21 7HT” it fills “A61 B”.
Any suggestions on what to do?
