    I am on my second iPhone 6 Plus (128gb) because my first one was replaced under warranty by Apple due to random resprings. Now my replacement 6 Plus is randomly respringing again :(

    Do any of you see pages and pages of JetsamEvents in your diagnostic logs? They can be found under General --> Privacy --> Diagnostic & Usage --> Diagnostic & Usage Data. A picture of my diagnostic log is here: http://i.imgur.com/0mwbp4L.jpg

    According to an Apple Genius who replaced my first iPhone 6 Plus, the high numbers of JetsamEvents in my diagnostic logs indicated there was a logic board fault. Now my replacement 6 Plus is showing the same symptoms.

    I don't understand - am I really unlucky? or is this a more widespread, software issue? I had setup my phone as new so I don't think it is backup related.

    Thank you for your help - I don't know anyone else who owns a 6 plus so I hope MacRumor can help me to find an answer.

    Please state if your iPhone is 128gb - want to get an idea whether it is more common on 128gb models.

    Just checked my 6+, and it has the same series of JetsamEvent logs as well. However mine does not randomly reboot.

    I have a high number but they are caused by backboardd. What are yours caused by?

    I have pages and pages of them but my 64GB 6+ has only rebooted once on 8.3 and a few times before that.

    Yes same problem as you since ios 8.3. Several reboots even after a fresh and clean install. I can only upload one of 2 pictures with jetsam events. Thank you for your information, I'm going straight to Apple store tomorrow!!!

    I just looked at mine and I have about a dozen JetsamEvents. Since I have owned my iPhone 6+ (6months) it has crashed twice. I am fairly sure the problem was caused by the Audible app.

    I have looked at the diagnostic logs before because I have had apps abruptly crash but the phone itself has always been very stable.

    if you have 8.3 installed on your device..that's the fw bug, springboard crashes several times,especially updating apps on the app store. there is nothing faulty on your devices. that's all about a fw bug.

    I have about 6 pages of crash logs, but only four entries for the JetsamEvent. I am not experiencing any random crashes or reboots.

    who has got the ''random springboard crash'' issue?

    Could you find any solution for that?

    I also had these with my 6 plus both of them (the replacement from Apple)

    As far as I know they are due to low memory, I had random reboots with my first 6+ none on my second but both I got at the minimum 2 jetsam entries everyday without fail, I finally had enough with the subpar performance (compared to the 6) and went back to the 6. It has been a few days now and not 1 jetsam entry yet (knock on wood) and haven't come across an app crash yet.

    Isn't a jetsamevent just a low memory warning of some kind? And then it records a log showing what caused the low memory and what apps were running when it happened? All normal behavior so then Apple can see what's happening if you choose to send the logs and eventually figure what's causing the "problem"? I think you guys are maybe overthinking this. I could be wrong somebody please chime in and explain this further if possible.

    I think maybe I should rephrase - I have had number of resprings (soft reboot). Have you seen those on your phone?

    ----------

    Yes, that's what I understand as wel. However, it seems like iPhone 6 plus users are seeing these jetsamevents much more frequently than 6, 5s or 5. And certainly, resprings are very rare when I was on 5s and on my friends 6. I wish I know if is this a software or a hardware issue?

    I have been posting the same question on other sites and 6 users are seeing between 10-25 jetsamevents over several months. Whereas I have over 130 jetsamevents in 2 weeks?

    The 6+ is a lemon, that's why. It runs a non-native super-high definition screen which is then constantly downscaled to 1080p. This uses resources and computational power and none of the other iPhones need to do it. Plus the same processor and GPU as the iPhone 6 has to push more pixels than any of the other iPhones even when the display output has been downscaled. Throw in a chronic lack of RAM, the same amount as the 32Bit two generations older iPhone 5 (32Bit devices use much less RAM than 64Bit devices), and you can see quite easily why the 6+ struggles more than the i5/5S/i6 when it comes to running iOS8.

    My first iPhone 6 plus was respringing everyday so I got a replacement. The replacement resprings much less but still happened 3 times in 2 weeks. Jetsamevents are still happening all over the place, more so than I have seen in 6 or 5s users. This leads me to think it's a hardware problem :(

    ----------

    That is what happened with some of jetsamevents. Not sure why or how to fix. I have at least several of those springboard ones per day.

    ----------

    Had any resprings?

    ----------

    So it never rebooted (0hone restarting showing an apple logo)? What storage size is your 6 plus?

    ----------

    Thanks for checking. What storage size is your 6 plus?

    I should rephrase - I have had several resprings and high number of jetsamevents. I experience less resprings now with the replacement (daily resprings to one a week). However, I still don't think they should occur that frequently as 6 and 5s don't share the same symptoms. If you get a replacement could you report back please?

    ----------


    That is a good explanation. I might not bother booking another genius appointment...

    I found that my resprings were app-related. Chrome used to do it so I deleted the app, and Facebook used to do it too but Google cured that several updates ago. 8.3 has also been the most stable iteration of iOS and a clean DFU install can help.
    Safari is now the biggest crashmeister for me. I get 'the webpage had to be closed down' message umpteen times per day, and the occasional full crash to my homescreen.

    Should I DFU install in your opinion? How is DFU install different from a normal restore?

    Well, you'll hear different theories on whether you need to but ultimately it puts a completely fresh copy of the o/s and firmware onto the phone. It ends up completely back to a factory state. You can then install a backup, or set up as a new phone.

    My 6 Plus doesn't reboot, not on iOS 8.3 and definitely not on iOS 8.4 public beta. But I have Jetsam Events caused by backboardd constantly. I've seen these occur on iPad Air 2 as well and I'm hoping  with iOS 9 improves this behavior.

    I only have 6 jetsam logs. Have had the phone since February. Not one reboot. Came with 8.1.2 and have updated OTA with both versions of iOS.

    My logs are long!! Including the same ones you mention and I have a 5c. I'll only worry if I get odd behavior!
