Between me and my wife, we have four devices. So... no.. Not really. Lol.
I used to have an S21 Ultra, Note 20 Ultra and S10e. My wife has an S22 Ultra. We also have an iPad which he uses for school, and he had some random Amazon junk kids tablet. Lol.
So... Yeah. We have a lot of devices. I had three mostly because I'm crazy. My son is special needs and unfortunately, using devices a lot of the portion of the time helps him with anxiety and is really stimulating for him.
That said, I have learned to be sneaky and turn on certain settings when he is using the device. The "extra dim" feature in particular is handy. Both me and my son use our devices at full brightness, which definitely contributes to screen burn.
