Hi I bought my iPad 4th gen at Christmas but I've never been able to download any apps

Your description suggests that you have purchased an iPad4 - which has iOS10 installed. As such, you have presumably purchased a used or reconditioned iPad.

If your iPad is currently running, or cannot be updated beyond iOS 10.3.3/4, then have an iPad4.

Update support for iPad4 ended September 2017. The final iOS releases for this model were iOS 10.3.3 (WiFi Only models) and iOS 10.3.4 (WiFi & Cellular). An iPad4 cannot be updated to any later major version of iOS as it lacks the minimum hardware requirements needed to run more recent versions. The 32-bit platform upon which the iPad4 is based is obsolete.

Most App Developers have dropped support for 32-bit devices and iOS versions preceding iOS11/12/13 - and have withdrawn older versions of their Apps from the Apple App Store. Withdrawal of Apps supporting older models of iPad is making their utility and usefulness significantly more limited. Once compatible versions Apps are withdrawn, you’ll not be able (re)download or (re)install them.

If Apps that you need to use now have higher minimum iOS-version requirements, your only option is to replace your iPad with much newer model. Of current models, even the entry-level iPad9 supports current iPadOS 15 - and has hardware specifications and capabilities that vastly outperform your old iPad4.

I hope this information is helpful - if only in clearly stating the fundamental limitations of your iPad4 and your available options.

You warranty relates to defects. As is, you appear to have a perfectly working, but obsolete, iPad - upon which you cannot install the majority (if not all) Apps that you wish to use.

Facebook, by example, requires iOS 12.4 or later - whereas you iPad cannot be updated beyond iOS 10.3.3/4.

The warranty itself is therefore redundant. Your only option is to explore the retailers returns policy. The learning point here is to understand exactly what you’re buying - before you part with your money.

Here is a list of the highest version of iOS supported by the older models of iPad (for simplicity - “generations” are shortened to a number) that are restricted in their ability to be updated:

iPad1 - iOS 5.1.1

iPad2, iPad3 and iPad mini1 - iOS 9.3.5 (WiFi Only models), iOS 9.3.6 (WiFi & Cellular)

iPad4 - iOS 10.3.3 (WiFi Only), iOS 10.3.4 (WiFi & Cellular)

iPad Air1, iPad mini2 and iPad mini3 - iOS 12.5.5

Newer models, not appearing in this list, are all able to be updated to the current version, iPadOS 15.3.1

You made a very poor and uniformed buying decision.

Sorry.

If your iPad model has been stuck on iOS 9 or 10 for all of these past years, then it is possible you own an over 9-1/2 to 10-1/2-year old, 2011 iPad 2 or 2012 iPad 3, 4 or 1st gen iPad Mini.

These iPad models cannot ever upgrade beyond iOS 9.3.5/9.3.6 or 10.3.3/10.3.4.

An over 9-1/2 to nearly 11-year old iPad is far too old, now.

Sorry.

Apple ended support for all 9-11-year old iOS devices nearly 5 years, ago, in 2016.

Third party app developers abandoned and stopped supporting these 8-10-year old iOS devices nearly 3 years, ago, in 2018.

There are, virtually, NO MORE third party apps available from the iOS App Store, any longer!

Third party compatible apps for such old devices are few and far between, now, in 2022.

This includes apps for both iOS 9 AND iOS 10 devices and, throughout 2022, ALL iOS 12 ONLY devices!

AND, NO WAY to, initially, install any older, compatible, third party apps into this old iPad, any longer!

NO MORE SUPPORT! NO MORE APPS!

All 2011-2012 iPad 2, 3, 4 and 1st gen iPad Mini models are fully and completely unsupported AND obsolete!

Sorry, but this is the reality for ALL 9-11-year old AND OLDER iOS devices now. Especially now, in 2022.

In addition, the internal, rechargeable batteries in these old iPads are, also, running on borrowed time.

Not worth the costs to replace these old internal, rechargeable batteries in these old iPads, any longer, either.

You really need to seriously consider a purchase of a new iPad model OR a much, MUCH “newer” and less expensive, refurbished or used iPad models, from better known, trusted Apple product/device retailers/resellers, some locally or from online, on the Web/Internet, capable of running the latest iPadOS versions.

There are PLENTY of less expensive, newer, older iPad models that can run the latest, current versions of iPadOS.

If you need OR ONLY able to purchase older, less expensive iPad models, look at older iPads from 2014 and later.

All of these older model iPads below, CAN, currently, run the latest releases of iPadOS 15.

2014, 9,7 inch screen iPad Air 2 models ( NO Pencil support )

2015, 7.9 inch screen iPad Mini 4 models ( NO Pencil support )

2015-2017, 12.9 inch screen iPad Pro models. ( 1st gen Pencil support )

2016, 9.7 inch screen iPad Pro models ( 1st gen Pencil support )

2017,10.5 inch screen iPad iPad Pro models ( 1st gen Pencil support )

2017, 9.7 inch screen iPad 5th gen models ( NO Pencil support )

2018, 9.7 inch screen iPad 6th gen models ( 1st gen Pencil support )

2019, 10.2 inch screen iPad 7th gen models ( 1st gen Pencil support )

2020, 10.2 inch screen iPad 8th gen models. ( 1st gen Pencil support )

2019, 7.9 inch screen iPad Mini 5th gen models ( 1st gen Pencil support )

Get the largest internal data storage model you can afford as NO Apple iOS device has ANY expandable storage.

I am sorry that you had to learn all of this, but this does not change any of the facts regarding these very old iOS devices.

If you can, try and return this very old iPad and get your money back.

Otherwise, please properly and responsibly recycle this device.

Sorry & Best of Luck to You!

If you decide to go down the path of purchasing used, secondhand Apple devices, here is how to avoid purchasing an Apple iOS/iPadOS device with user activation lock, in the future.

If you purchase any iPad, or any Apple iOS device, for that matter, used/second hand, online, or even in-person, make sure this iPad does NOT have user activation lock and has been properly reset for sale.

A properly reset for sale iPad should initially power up to an animated, multi-language “Welcome” screen.

DO NOT take the iPad seller's word that this iPad is user activation lock free!

We have seen plenty of used iOS device purchasers get scammed.

User Activation Lock can never be bypasss, circumvented or worked around IF there is no correct previous/original user information to be able to do so.

Apple doesn't get involved with ANY user activation locked, used/second-hand sold devices, either.

So, buyer beware!

If purchasing a used device in-person, power the iPad ON

If the iPad DOES NOT display the initial animated, multi-language “Welcome” screen, then pass on purchasing this iPad.

If the iPad powers up to any other screen, then forget purchasing this iPad.

You cannot trust that the seller actually has the correct needed info to properly reset the iPad back to factory settings right then and there before the actual purchase and exchange of money for the iPad, in question.

Pass on the device!

If you are purchasing this used iPad online ask the seller to provide multiple images, either online or be sent to you via email, showing this animated, multi-language “Welcome” screen of the interested in purchasing iPad model.

Even better, ask for a short video be sent to you showing this animated, multi-language “Welcome” screen, in action and in its entirety, posted to the online ad or emailed to you.

If the online iPad seller refuses any of these requests, pass on the iPad. DO NOT buy!

Good Luck to You!
