site doesn't work well on android tablets (JS problem)

Hi,

I have a site which doesn’t load well on most android tablets.
the design is based on JS and I think there might be a problem with its loading.
On iPad the site works pretty well with no problems.

Can someone here please guide me to where I should start looking for the answer.

this is the site: https://www.itzikalbo.com

tnx ahead
