My personal best "trick" is to not zoom but to use landscape instead. The upper slider works better than the lower than, but I manage to use them both.
This has worked for me on my Samsung Galaxy S4 and my S6. It also works well on my Samsung Tablet 8.4", unsure of the exact model number. I don't know in detail how my girlfriend does it, but she uses an S5 and manage too at least.
But yes, ideally it should definitely work smoother with Android/Chrome.
