Hello,

Its Because your hardware, CPU and RAM is old and cant support newer versions of iOS

Hope I Helped

Last time: It is NOT POSSIBLE to update your phone to anything later than 12.5.6. It is NOT compatible with anything higher.

If you want apps that require something later, you need to BUY A NEW PHONE.

That is not possible. The iPhone 6 is not compatible with anything later than ios 12.5.6.

No. 12.5.6 is as far as it can update.

It lacks the hardware, CPU and RAM, to run anything newer.

You cannot install Facebook on an iPhone 6. You need a device capable of running at least iOS 13.4.

Your iPhone 6 is now too old to run the current Facebook app version.

I’m afraid there is no hope.

The only way to solve your problem is for you to buy a newer iPhone.

You cannot install Facebook on an iPhone 6 anymore. It's too old. Nothing can be done at this point.

The solution to your problem is to buy a new phone.
