Problem: Bluetooth issues
As with other smartphones, people have been having trouble maintaining a Bluetooth connection, either with 3rd party wireless headphones, or when trying to connect their iPhone to a car. Some users have also noticed a much larger drain on the battery when using it.
- Restart the phone.
- Toggle Bluetooth off and on again.
- Unpair the Bluetooth devices and try pairing them again.
- You can try resetting your network settings by tapping Settings > General > Reset > Reset Network Settings. Then try Bluetooth again.
- iOS 10.2 contained improvements for Bluetooth performance and connections to 3rd party accessories. If you’re not running 10.2 or 10.2.1, those updates may alleviate the issue.
- If you’re noticing a bigger battery drain like this user, the cable you’re using may be the culprit. Consider using the Lightning cable that came with the iPhone or better quality cables.
- Perform a factory reset, restore your phone using a backup (or as a new phone) and try Bluetooth again.
Problem: Camera displays a black, green, or purple screen
This issue affects users with the iPhone 7 Plus. Users on the Apple discussion forums and on Reddit often complain that their iPhone 7 Plus shows a black — or sometimes a green or purple — screen when they try to use their camera. Sometimes an error also appears, one that says “Emergency iPhone needs to cool down.”
- The first thing to do is to try the steps listed on Apple’s support site.
- If the aforementioned steps don’t resolve the issue with your camera, it is likely that your iPhone 7 is suffering from a hardware problem. In that case, we suggest that you contact Apple support. Many users with this issue have gotten their iPhones either repaired or replaced.
Annoyance: Black paint chips or peels
Apple told us about the micro-abrasions on the glossy finish of the jet black iPhone 7, which was prone to scratching. However, a thread that is reaching epic proportions on Apple’s discussion forums shows the regular black finish on the iPhone 7 is prone to chipping and peeling, even when encased.
- Unfortunately, Apple’s warranty doesn’t cover this kind of cosmetic damage. Some users have ended up selling their iPhone and getting another iPhone 7 in a different color.
- According to a post on the Apple support forums, a customer who goes by the username xfuz1on was able to escalate this issue to a supervisor. The supervisor then asked this customer to send in pictures of the iPhone 7, and he was able to get his phone swapped at an authorized service center.
In a thread that spans the current lifespan of the iPhone 7, users in the Apple forums have complained about their iPhone 7 getting uncomfortably hot. It is normal for smartphones and other electronic devices to get hot when they’re performing certain tasks, however. For example, an iPhone can get warm while you’re broadcasting live video, using Snapchat, playing games, or doing other tasks that will push the CPU to its limits. While it is normal for it to get hot while doing CPU-intensive tasks, your iPhone should return to a normal operating temperature when you’re done.
- A misbehaving app could be what is causing your iPhone to overheat. This app could also be working in the background, and making your iPhone overheat. Check for any apps that were just updated — after all, this issue is often caused by a bad update. If you can’t seem track down the issue, you can follow our guide on how to restore your iPhone.
- If you have reset and restored your iPhone and the issue persists, we encourage you to contact Apple support. A smartphone that is prone to overheating could be suffering from a dangerous hardware problem, one you’ll want to take care of as soon as possible.
