- A movie with a length of 4 seconds can make sure that you get stuck iPhone. Only a hard reset (by the On / Off button and the Home button simultaneously pressing) helps. Probably the movie is corrupt and iOS do not good to deal with.
The video surfaced last week, and when it appeared that the crash left WhatsApp and thus even had bogged down the whole phone. Meanwhile, it is also on YouTube. In Safari browser, the phone is getting slower, but continue to limit the consequences.
Presumably, the problems are caused by a problem in the way iOS omspringt with memory. This can be solved by Apple in an update of iOS. The movie is causing problems in all versions of the operating system.
