System problem

Please try the following:

1. Try connecting to a network with a better signal. An unstable network may cause the downloaded upgrade package to be damaged or missing.
2. Ensure your phone has enough storage space, so the download of the installation package can be completed.
3. Ensure your phone's has more than 40% power — less won't allow OTA upgrades. Upgrade after charging your phone for some time.
4. Avoid using your mobile phone during the OTA upgrade, so you don't interrupt the upgrade. If you've used it during the upgrade, perform the upgrade again.

If the above methods do not resolve your issue, please contact the Nothing customer service team for further assistance.

Please try the following:

1. Check if there's an updated version.
2. Check if there's enough mobile phone memory by going to Setting> Storage.
3. Check if your network connection is stable or switch to 4G.
4. Uninstall the software and reinstall it with the update.

If the issue persists, contact the Nothing Support Team for further assistance.

After your phone is cleaned up, software will run in the background because of the way the Android system is designed.

There's nothing you need to do. It's normal for your phone to be slow to boot after an upgrade, as the system needs to reload all the data.

Please try the following:

1. Go to Settings> Apps> See all Apps> Find the App> Storage & Cache> Clear Storage and Clear Cache.
2. Swipe up the home page to enter the recent app page, clear all applications and then try again.
3. Uninstall and reinstall the application.
4. Back up any important data and restore your phone to factory settings.

If the issue persists, contact the Nothing Support Team for further assistance.

Phones are generally suitable for use in an environment with a temperature between 0°C and 35°C. If the temperature is too high or too low, it'll affect your phone, cause it to heat up or fail to charge. In severe cases, it can cause damage to your phone and battery.

Precautions:

1. Don't use your phone for a long time in a high-temperature environment, especially in summer.
2. Choose thin, breathable protective cases over thick ones (leather or metal). When your phone is charging or the temperature rises, take off the case and let the screen rest for a while.
3. Choose a qualified phone radiator with good heat dissipation and cooling performance, or apply a wet tissue on the back of your phone to help dissipate heat.

Heat usage scenes:
1. High-power consumption scenarios

a) Weak signal
When the WiFi signal and phone signal are weak, your phone will increase the power of transmitting and receiving signals, which, in turn increases your phone's power consumption. It also increases when you use 5G.

b) Gaming
To ensure the quality and smoothness of the game, chips such as the CPU and GPU of your phone need to operate at high performance, causing it to reach its maximum temperature after 20 minutes.

c) Video watching
The screen, data processor, and image processor of your phone are in a long-term working state. For example, when you watch a video or live broadcast, high resolution and bitrate will increase your phone's power consumption and generate more heat.

d) Many backgrounds
Your phone will heat up faster if there are too many programs, pop-up windows, search signals or networks in the background, or if you have WiFi, GPS, NFC, Bluetooth or other functions enabled at the same time.

2. Charging scenarios
Charging your phone means converting energy. The charging device will generate a certain amount of heat during operation, which will cause your phone and charger to heat up to a certain extent. This is normal. The charging power is relatively large, especially for phones that support flash charging and super flash charging. The energy generated during charging is more, and the temperature will be higher than that of ordinary mobile phones.

Suggestions:
a) We recommend you use the official standard charger for charging and don't place your phone in an environment with high temperature and poor heat dissipation.
b) Avoid using your phone while charging. If your phone continues to run during charging, the CPU of the phone will be burdened and heat will increase.

Kind tips:
1. Your phone needs hardware to work during operation. While in use, it will generate heat. This is normal.
2. If your phone is inexplicably hot or cold, we recommend you shut it down for a period of time and then restart it. If there is no obvious improvement, please contact our Online Customer Service or take the purchase invoice, warranty card and mobile phone to the maintenance center designated by Nothing for inspection and treatment.
