Greyscale

Hi,

I own a S 6 edge + (before I hat a S6 edge) these are woderful phones but a bit bloated by all crappy google stuff and such and I clearly start to think that the cellular conception lacks seriousnees as these phones, particularly the edge + are seriously challenged in that department...

Anyway, as a matter of trying to improve battery life I've set accessibility/direct access/greyscale but taping 3 times the home button has me concerned about it's lifespan... Does someone know an application or a script allowing to access these parameters without the home button ?


Thanks.
