How to fix common problems like random reboots, battery drain, colour balance and more in OnePlus 3

OnePlus 3, one of the most awaited phones of the year, was recently released by the Chinese manufacturer and users already seem to like the experience. Users are at the same time experiencing some day-to-day issues with the phone with many complaining about the RAM management. Although OnePlus has issued a new update to fix these bugs, there are still a number of issues.

IBTimes UK tells you how to address these everyday problems of the OnePlus 3:

Battery draining quickly

• Any unused applications running in the background have to be cleared. You can do this manually by going to Settings>Apps or by a third party application like Clean Master.
• As it is the latest Android system version with high performance and advanced features, it may not have the same battery backup compared to the older versions, but it will be optimised with future updates (battery backup may differ based on usage)

Fingerprint scanner not working

• When registering a fingerprint, make sure all sides of your finger are covered
• Always register two to three fingerprints
• Make sure there is no liquid or other material like dust between the sensor and finger when trying to unlock the device
• Do not press too firmly
• If it is still not working, press the power button for 10-15 seconds to restart the device and then try the fingerprint scanner again when the device is on
• If the problem still persists, delete all the fingerprints and register them again

Disappearing ringtones

Some OnePlus 3 owners have recently have taken to the OnePlus forum to complain about errant ringtones. They say ringtones are completely disappearing when updating the phone's software. To resolve the issue, head to Settings > Alert Slider > Priority Settings and switch both the 'Messages' and 'Calls' options to 'From Anyone'.

Phone not switching on

Sometimes when the charge is completely drained, the phone may not be able to power up. In that case, hold the Power button for 20 seconds five times or hold down the Power button along with the Volume down button to start recovery mode and performing a factory reset.

In case this does not work out, follow these steps:

• Leave the device for 12 hours without putting it on charge at all
• Now charge with the official charger only for 6 hours
• After 6 hours, disconnect the charger and reconnect it
• You will see a low battery screen. At this point, do not try to switch it on and let it charge for at least an hour or until it has at least 10% charge
• You can now boot the device and keep charging normally

Push notifications not working

If your push notifications are not working, there are two ways to address this:

First method: Go to Settings > Sound & notification > App Notifications and manually select which apps can push notifications. Make sure that no applications are added to the Do Not Disturb list. Now take note of the Alert Slider. If the slider is pushed down, you will receive all notifications; if it is midway you will get only priority notifications; and if it's pushed all the way up, the device goes into silent mode; thus no push notifications will be received.

Second Method: Alternatively, one can even use third party apps like Push Notifications Fixer, that can be downloaded from the Google Play Store. There is a separate version of this app for users who have root access.

Random Reboots

This problem has more or less been resolved in the latest version of OxygenOS 3.2.1, but in case you still face the issue, you can take the steps below:

• Let battery be fully drained and leave idle for 10 minutes
• Now plug it into the charger until the battery is fully charged
• Now go to Settings > Backup & Reset > Factory data reset > Reset phone > Erase everything

Random reboots can take place for various reasons including hardware faults. So in case these don't work, do visit the nearest OnePlus Support to get your phone repaired or replaced.

Setting the colour balance

The OxygenOS 3.2.1 has introduced a sRGB mode which should take care of colour contrast issues but in case that doesn't happen or you are not happy with the colour tone, you can head to Settings > Display and toggle the 'Colour balance' slider until the levels are to your liking.

Photos not saving when using camera

If you encounter this peculiar problem, follow the steps below:

• Do a full backup in TWRP (system, data, boot) and copy it to your PC
• Now format data and copy back the backup from PC and restore it in TWRP
• The device will restore the exact same backup if taking photos failed to work before

Audio quality of videos

Some users, after recording videos on the OnePlus 3, have complained of audio issues. There has been no solid work around for this except for downloading some third party video applications that enhance the volume. This issue software wise has been solved by the OxygenOS 3.2.1 update, according to the company. In case there is a hardware issue, do get the device checked as the microphone may be faulty.

Android Wear paired with OnePlus 3 not showing notifications

Those who have paired their Android Wear to the OnePlus 3 but are facing notification issues should be able to resolve them by updating to the latest Oxygen OS 3.2.1 update. In case you still feel there is a problem you can solve it by following these steps:

• Make sure the Android Wear app is updated to the current version
• Unpair your device completely and re-pair after restarting the phone
• Make sure the Android Wear app is excluded from Doze mode
• Check the Alert Slider on the phone and make sure it is not in the middle or top position, as notifications are limited or turned off completely
• Do not use the "kill all task" option found on the recent apps screen, as it affects the Android Wear app
