There really isn't a fix for that specific problem as it was Apple's poor decision making, just like it was back when iPad 3 released, and the same when iPod touch 4th gen got 256MB Instead of the 512MB in RAM. iPad Air SHOULD have had at LEAST 2GB of RAM. Sure the iPhone 5s can deal with 1GB but its a PHONE not a TABLET....
Yes, I know about the memory issue related to the 64-bit apps, but that's not what I'm seeing.
First, low memory conditions shouldn't be crashing apps as soon as you start
using the webviews, whereas the apps without the web view are working just fine. For an example, Feedly app, it works consistently fine as long as I don't open a web view in it. As soon as I start doing that, it crashes.
The same for Twitterrific and Felix, they all work fine as long as I don't open any web views. As soon as I do, they start crashing.
Hell, even once in a while, I only opened one tab in Safari before it starts crashing. Sorry but one tab does not eat up more than 512mb of memory. The iOS should be terminating all the backgrounded apps before it starts crashing. I mean even Safari 7 on Mavericks loading this page is eating only 300MB.
I haven't even seen any games crashes yet on iOS 7, and that's generally the type of apps that'd eat up most of the memory.
The only technical difference between iPhone 5S and iPad Air, is that iPad Air have more pixels to push. Beside that, they're the same identical hardware running the same identical OS. Yes, the iPad Air would have less memory, however, that's not an excuse for memory leaks leading to crashes if it is the Safari that's the cause here.
