Frequently asked questions
What chip is in US Galaxy S26 Ultra?
Samsung’s US Galaxy S26 Ultra page names Snapdragon 8 Elite Gen 5 for Galaxy (also styled Snapdragon® 8 Elite Gen 5 for Galaxy). This page is locked to that US naming. Do not substitute another region’s silicon without a new caption.
Does S26 Ultra have 100× zoom?
Not on the US marketing page excerpt accessed 2026-09-19. Samsung’s own FAQ on that page lists a 50MP Telephoto with 5x optical zoom and 10x optical quality zoom, plus 200MP Wide F1.4 and 50MP Ultra Wide F1.9. Do not paste reseller 100×.
Does iPhone 18 Pro have an S Pen?
No. Apple’s 18 Pro spec sheet lists Action Button and Camera Control, not a stylus. Samsung’s US S26 Ultra FAQ: “Yes, Galaxy S26 Ultra has a built-in S Pen.”
How much RAM does each phone have?
Apple does not publish RAM on the 18 Pro spec sheet. Samsung’s US page lists 12GB RAM with 256GB or 512GB storage and 16GB RAM with 1TB. Do not invent an Apple GB figure.
What is the 18 Pro start price?
Not published on the 18 Pro spec sheet excerpt (accessed 2026-09-19). Samsung’s US S26 Ultra marketing excerpt on the same date also does not print a US start MSRP (it does advertise trade-in credit). Date any street price.
