Many users in Australia experience problems with their iPhone 12 series, including the iPhone 12, iPhone 12 Mini, iPhone 12 Pro, and iPhone 12 Pro Max. Common issues include fast battery drain, overheating, green screen glitches, ghost touch, and speaker failures. These problems often come from iOS update bugs in iOS 14, iOS 15, or iOS 16, or from hardware faults like OLED display or A14 Bionic chip defects. The good news is that you can fix these issues through trusted solutions, including Apple Support, AppleCare+, or Apple Authorized Service Providers.
Fix Battery Drain and Overheating on iPhone 12
Battery drain and overheating are common problems for iPhone 12 users. Many people report that their iPhone 12 battery performance worsened after updating to iOS 14 or subsequent versions, including iOS 15 and iOS 16. Overheating is often seen during gaming sessions or when using 5G data. These issues can be caused by iOS bugs, background apps, or hardware-related factors like battery wear.
Overheating is also common during gaming or while using 5G data, as these tasks put extra load on the device. Over time, the battery itself can lose capacity, and in some cases, hardware issues such as problems with the OLED display or A14 Bionic chip may also make things worse.
How to Fix?
- Check your battery health in Settings.
- Update iOS to the latest version.
- Use Low Power Mode to save energy.
- Reduce screen brightness or background app activity.
- If the issue continues, get help from Roobotech’s repair services for a battery replacement or diagnostics.
- You can also upgrade to other models such as the iPhone 11 or latest iPhone 16 for better battery performance.
Fix Screen Unresponsiveness and Ghost Touch on iPhone 12
Many iPhone 12 users experience screen problems such as flickering, unresponsiveness, or green tint. Users also face problems where the screen does not respond to touch or starts tapping on its own. These issues usually appear after a software update, accidental drops, or hardware failures in the OLED display or digitizer. Ghost touch often happens when the screen detects taps you did not make, while the green tint problem is most noticeable in low brightness settings.
These problems can be caused by iOS bugs, loose display connections, or damage to the screen assembly. In some cases, background apps or system glitches may also trigger these errors.
How to Fix?
- Start with a hard reboot, Apple recommends this for screen issues like the iPhone screen flashing green.
- For iPhone 8 or later, press and quickly release the Volume Up button, then press and quickly release the Volume Down button, and finally hold the Side button until the Apple logo appears.

Fix Camera and Face ID Issues on iPhone 12
Blurry photos and Face ID not working are common problems faced by iPhone 12 users. These issues usually happen due to dust or damage in the camera lens or a faulty Face ID sensor. Sometimes, outdated iOS software can also cause these features to stop working properly. Cleaning the camera lens gently and updating the iOS can fix minor issues. If the problem continues, it’s best to get the device checked by a professional.
How to Fix?

Fix Storage and Performance Issues on iPhone 12
Many iPhone 12 users in Australia face problems like slow performance or constant “Storage Full” alerts. These issues often happen when the phone is overloaded with apps, photos, and files, or when background apps and system glitches use up memory. Outdated iOS updates can also slow things down. To fix this, it's important to clear unnecessary data, update your phone regularly, and restart it often to refresh system functions. Taking these steps can keep your iPhone running fast and smooth.
How to Fix?
- If your phone is full of apps, photos, or videos you do not use, delete them to clear storage. This will help your iPhone run faster and fix the “Storage Full” issue.
