Minimum optimized iOS support for layout

Hi there, I just found an inconsistency after my app was rejected due to layout support on iP4. I want to low to iP4 to not miss out on legacy users. Anywho, I played around with xcode and iOS versions & simulators and realised this:

when running iOS 10.3 with iP5, app layout on the main page looks as it should

simulating iOS 8.1 with iP5 ( it’s technically same screen), the elements are not placed correctly. See the placement of the arrows and the symbols

Any ideas regarding this?

Seeing the code used to build this UI could help.
