Okay so, I've been checking this thread for quite a while - since I started getting these "Springboard" crashes when switching apps. Always seemed to be related to having Safari open. SO Safari with some tabs, then other random apps. At some point I was getting 2-3 springboard crashes per day. Very quick, just show the logo for a couple of seconds, then back to the pin pad. iOS 9.3.4 did not fix it, then I went to 9.3.5. I remember for sure that I have tried setting up Safari in different ways, and at some point I just disabled the Javascript engine (and I have continued using Chrome for stuff that required JavaScript)
So thing is, the crashes stopped. I hadn't have one for like weeks. Then I went back, and re-enabled Javascript in Safari. This was 2 weeks ago. No crashes whatsoever, ever since. The "bug298" that we all see in "diagnostic and usage", also called the "JetsamEvent", is common to ALL devices. Just went into an Apple store in Manchester and quickly checked almost all the devices: ALL had "bug_type":"298" events in the logs. I checked current iPhone models, the 12.9 inch iPad pro, the small iPad Pro, iPad minis. All had this in the logs, several times. I am still getting them daily, but hadn't had a crash ever since.
I am hoping it was, in fact, iOS 9.3.5 that fixed it. Dont' know. The crashes did not come back after I re-enabled JavaScript in Safari, so it was just a coincidence, it seems.
Now with all that being said.. I am waitign to see what iOS10 brings to my iPad Pro 9.7. - because if there are ANY reports of the springboard crash again, I am staying on 9.3.5. O.o
My device is a 128 gig iPad Pro 9.7in, WiFi only, model MLMW2B/A.
(edit: first I wrote "128 megabyte".... LOL .. you can tell I'm from the 80's 😀 )
Cheers and yeah.. first ever post in here 🙂
