Update: This does just makes it a bit better for awhile, if at all. The problem is that Apple used only 512Mb internal memory on the first generation iPad, so all apps taking up to much memory are force quit automatically. Looking at the crash logs it all points to the same problem. Low memory. The first generation of iPad was released April 3, 2010. I would try to buy a new iPad or try to find a used iPad Air that can run the latest iOS and apps. It’s now almost six years old, it’s time to start using it as a door stop.
It looks like I finally found a solution to my iPad crashing problem. My first generation iPad crashed all the time without any apparent reason. I found it on a forum and I’ve been running my iPad all day without one crash. Haven’t been able to do that since upgrading to iOS 5.01.
If you do this, do a backup of your iPad with iTunes before attempting this fix!
All you need to do is to reset all settings. Open the Settings app and under General and choose Reset. Press Reset All Settings. This sounds dangerous, but you won’t lose any data, only your settings. The machine will show a progress bar, which is normal. After the machine is reset, you should now hopefully have an iPad gen 1 that doesn’t crash all the time. All the settings for mail etc wasn’t affected by the reset by the way.
