QUESTION
What is the best phone for seniors who only use WhatsApp and photos?
Best pick: Google Pixel 9 — if they only use WhatsApp and take photos, it keeps the experience simple while giving much better photo quality than most senior-focused phones.
If ease of use matters more than camera quality, choose the Lively Jitterbug Smart4. If the family mostly uses iPhones and can help with setup, choose the iPhone 16 Plus.
I would avoid most flip/basic senior phones for this use case unless you confirm WhatsApp works on that exact model; many are better for calls/texts than app-based messaging and photos.
