Mine is people using are instead of our. I hear this all the time from social media, news reporters, and I see in in writing. Instead of our, they use are as if they forgot the word our exists.
Autocorrect always seems to choose the wrong spelling for its and it's. If you're trying to use the possessive, it changes it to "it's." If you're trying to use the contraction of "it is," it changes it to "its." π¬
I never had these dumbass incorrect context changes when autocorrect was new. It only seems to get worse over time, instead of better. It shouldn't even be correcting words that are already spelled correctly, even if the context is wrong.
Autocorrect has gotten significantly worse for me recently. I used to be pretty well adjusted to my phone and know which words I did not need to capitalize/spell correctly because autocorrect would do it for me. Now, it feels like it is all over the place. It also does not seem to acknowledge commonly used proper nouns anymore. I type my brother's name all the time, yet it will autocorrect to the same name witn different spelling.
You can usually remove predicted words if this starts happening. On mine, it's done by pressing and holding the prediction, then confirming. If you use the name Scott regularly anyway, it'll re-learn it without the incorrect association
Last week I texted my wife "I desire chicken" and Autocorrect tried to change it to "I desire children. I don't, Autocorrect. In either sense! What sick game are you playing...?
