WhatsApp Crashes on iPhone - How to Fix It
I am a big fan of WhatsApp because it allows me to communicate with family and friends without charging fee for sending text. However, I am not that happy with WhatsApp as it goes wrong frequently. For example, it crashes on startup when I open chat or contacts after I switch to the new iPhone 6s. Or it just keeps exiting and rebooting itself which can be annoying when I am indulging in a conversation. For the sake of getting myself from these situations, I search online and turn to my salted friends for useful ways to fix WhatsApp crashes on my iPhone. Let me list them out one by one.
Scenario 1: If you have recently installed Facebook with contact sync enabled to your iPhone Address Book, most likely that is the culprit leading to WhatsApp crashes on iPhone. The way to fix it is disabling Facebook sync.
1. Open Facebook app on your iPhone. Then, go to More at the bottom menu bar. Next, select General among all the options to enter Settings page.
2. Find the option Upload contacts. Tap the green button and turn it off. There will be a pop-up occurs saying that "Stop continuously uploading your contacts", select the "Turn Off" button.
3. Launch WhatsApp to see if the problem has been solved. If yes, that's it.
4. If no, you will need to restore your Address Book with latest iTunes backups.
