My boyfriend didn't look at my mobile phone before, but he has been looking at my mobile phone every day recently.

Generally speaking, people do things habitually, such as the route they take every day, eating at a certain time, or buying things in a fixed store.

If there are different actions suddenly, either the individual wants to try or the external stimulus or influence.

Although the relationship between men and women is close, there are always some privacy that can't be touched, and some couples will fade or erupt with the backlog.

I'm here to give you two suggestions: first, ask why directly, not too bluntly, and ask in a heart-to-heart tone.

Second, carefully observe his expression after watching the mobile phone. If there is no response, you can ask directly, maybe it's just a whim or something. If you are obviously relaxed or angry, it means that you are looking at it with a purpose. At this time, you'd better carefully check whether there is anything in your mobile phone that will affect his mood. If not, please use the first suggestion again.

Since I don't know the cause and effect, I can only give two suggestions. If you have any questions, you can add them or trust me privately. I will reply as soon as I see them.
