I can’t use my WhatsApp

i am finding it difficult to update my iPhone 6s Plus software, it’s version is 15.8 and am seeing coverage expired too.

How do I fix it?

The iPhone 6s Plus ran iOS 9 when Apple first released it, in September 2015. It received six major iOS updates but will never be able to update to iOS 16, 17, 18, 26, 27, or beyond. The developers of many apps have abandoned iOS 15, and your iPhone 6s Plus. If you want to run current versions of their apps, the fix is to purchase a new phone.

As for the "coverage expired" indication, that is expected, as the 1-year limited warranty on that phone would have run out many years ago.

You cannot pick and choose an iOS version. What you get is Settings > General > Software update > [All options are available here]

If iOS updates are no longer being released for your device, it typically means that the device has reached its end of life in terms of software support from Apple. In such cases, there are a few options you can consider:

1. Although major iOS updates may no longer be available, Apple may continue to release security updates for older devices. Ensure that your device is running the latest available version of iOS for its generation to maintain the highest level of security.
2. As iOS versions advance, some newer apps may not be compatible with older iOS versions. You may need to rely on older versions of apps or find alternative apps that are compatible with your device's iOS version.
3. Ask the App developer to release the app for lower iOS versions also. Netflix & Amazon have done it.

8. If your device is no longer receiving software updates, it may be a good time to consider upgrading to a newer device that is supported by the latest iOS updates. Upgrading to a newer device will ensure that you continue to receive the latest features, security updates, and app compatibility. Selection of a mobile model/brand is driv… - Apple Community
9. Check for App Alternatives: Look for alternative apps that provide similar functionality but are compatible with your current iOS version. There might be other apps available that cater to your needs and are compatible with iOS 15 or lower.
10. Consider Device Upgrade: If your iPhone 7 is not able to run the required iOS version, you might consider upgrading your device to a newer model that supports the latest iOS updates. This would ensure compatibility with the Artists app and other apps that may require newer iOS versions.

Remember to regularly back up your data to avoid losing any important information during the transition to a new device.

It's worth noting that the availability of updates and options may vary depending on the specific device model and its hardware capabilities. 

As far as "I can't use my WhatsApp", contact WhatsApp for help with their app and their service.

The current version of WhatsApp Messenger in the App Store only requires iOS 15.1 or later - so if the WhatsApp Messenger app is available in your country/region, you should be able to install it on your iPhone 6s Plus (for now).

The WhatsApp Business app is iPhone-only, but it, too only requires iOS 15.1 or later.

That model can be updated to iOS 15.8.8, no further.

Yes, warranty coverage will be expired on a 10 year old device.

There is nothing to “fix”.
