Slightly raised screen above bezel at the bottom

Zenfone 2 is brand new a few days . The left side screen right below the back and home buttons is raised slightly above the bezel. If I run my fingers upwards I can feel the raised screen. If I push it down with slight pressure for a few seconds it will stick for a few minutes but then slowly raise again. The raise is very small. Its hardly noticeable but i just do not want it to turn in to something else big

Is any of your phones the same way? Should I do a warranty return?

I might do a advanced replacement with ASUS if they are sending me a new phone
