Remotely changed language

Today as I was walking from my restroom back to my living room, someone remotely changed the language on the Tmobile 5g Sagecom 5688W that I have. I first noticed that it was lit up, so I looked closer and watched as the language changed to spanish. Then I grabbed my phone and restarted it via the app and manually changed the language back to english. 

My question is, has this ever happened to anyone else?
