Whatsap is not working on my iPhone 6s
Each time I tried to download WHATSAPP on my phone it states always that I should update the software to iOS 13. Presently my phone is on iOS 12.5.6. Is iPhone 6s no more compatible with WHATSAPP?
If you’re at iOS 12.5.6, you have iPhone 6, not iPhone 6s.
There is no way for an iPhone 6s to get to iOS 12.5.6.
iPhone 6 is forever at iOS 12.
Your options are a newer (used, refurb) or new iPhone.
iPhone 8 or newer is required for iOS 16.
