i've had instability ios 11 on iphone 7+ every day, multiple times day, since installed ios 11 on launch day, end having restart phone resolve. has been case 11.0, 11.0.1 , 11.0.2.
when phone becomes unstable:
- the network activity spinner in top left spins continuously.
- the settings app can't opened. if tap on settings, opens blank app template white empty screen , never renders ui.
- some other apps, randomly can't opened. might open launch screen or blank settings. if hit home button after opening 1 of these stuck apps, springboard comes fraction of second, app screen reanimates open fraction of second, springboard comes up.
- some apps open have long lag of 5-15 seconds before interface usable , interactive.
- some apps open , work normally.
- eventually, entire phone become unresponsive.
- finally, after being unresponsive time, phone have blank black screen spinner in middle spin continually.
- the way phone work after hard reboot holding down sleep/wake , volume down few seconds.
if reboot phone when starts exhibit these symptoms holding down sleep/wake , sliding restart, before becomes unresponsive (item 6) phone reboots , works normally.
i've tried number of troubleshooting steps. thought might problem related on air installation of os, or system file corruption. 11.0.2. cleared phone entirely using "restore iphone..." itunes , restored itunes backup. did not resolve issues.
thought might related bluetooth problems, shut off bluetooth entirely past few days. did not resolve problem.
what have noticed last 2 times had instability there @ least 1 app shows updating, looks download complete , trying complete installation. in other words, there dark circle mask around icon , middle of loading part not dark. apps not launchable , cannot delete them springboard. after restart phone, mask gone , apps installed , usable.
i believe instability might caused problem @ end of app installation/update process. in order test theory, have gone gone itunes , app stores settings , turned off automatic downloads. if theory correct, instability should no longer occur.
if else having same symptoms above, can try turning off automatic downloads , report here if or not eliminate instability you.
also, if else having instability , has not turned off automatic downloads yet, please check see if have apps in updating state while phone still responsive , post observations here.
report daily how things have been going me. thanks!
you restored itunes backup, problem. restore phone new. restoring backup restores devices how was, including software corruption issues.
