Obviously, WhatsApp has been causing a lot of bugs to those using iOS 8. The problem (initially due to some other reason including type/letters) is now spread across a variety of possible causes. We don’t really know what the problem is. But we have a few solutions.
if you are running iOS 9 on your iPhone, please refer this post.
#1. Turn off WhatsApp iCloud Backups
iCloud Drive can be the biggest problem of all. Since this feature of iOS 8 involves a lot of variables, most problems crop from this. First off, app developers have to update their apps to work with iCloud Drive. Next, iCloud Drive doesn’t support older iOS and OS X versions which is another problem. And finally, even if all these variables are right, some issues still keep coming up. (That is why we wrote about not enabling iCloud Drive)
Turning off auto-backup (anything that uses iCloud) is one possible solution you should try. To do this:
- Open WhatsApp
- Tap on Chat Settings
- Now tap on Chat Backup
- Tap on Auto Backup
- Select Off
#2. Disable iCloud Drive
We’ve covered this before but it’s worth repeating. If you enabled iCloud Drive when you setup iOS 8 on your iPhone 6 or other iPhones, you might have to disable it.
Disabling iCloud Drive is easy.
- Go to Settings → iCloud
- Tap on iCloud Drive
- Turn off the switch.
At the time of writing this, there’s no indication that WhatsApp is using/configured for iCloud Drive (although the next update would be). But this seems to have randomly worked in fixing WhatsApp crashes. So give it a try.
#3. Re-install App (No Backups)
This is obviously a pain to do. And since it means losing data, most people might not try this. But if you’re at your wit’s end, re-installing WhatsApp and not restoring from backup might help (as it did for some folks)
Delete the app and then re-install it. Only, this time, don’t restore when WhatsApp asks you to. Set up as new and you might have a smooth run.
#4. Restore/Upgrade through iTunes
If you updated to iOS 8 through iTunes, chances are that all of WhatsApp data was restored too – which could be causing the crash. If you are at this stage where you are about to restore/re-upgrade through iTunes, one piece of advice would be: don’t restore apps from backup.
You will need to set up the device as new and then install apps individually (that’s easy from Updates → Purchased Apps in App Store)
Again, while setting up WhatsApp, follow #3 and don’t restore from a former backup.
