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:

2. Charge your phone via the USB interface: connect your phone to a computer or another device through the data cable. When the connection method dialog box pops up, click Only Charge.

Learn what the battery and charging icons mean.
You can tell the current battery status from the battery icon on the phone's status bar and the lightning bolt icon next to the battery.

Note:
After the battery percentage is turned on, the battery icon will display the battery value. You can turn the icon on by going to Settings > Battery> Battery Percentage.

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, causing 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.

Causes and solutions:

1. Fast power consumption in a low-temperature environment:
At low temperature, the performance of the lithium battery deteriorates, resulting in increased power consumption. This is normal. Wait until your phone returns to normal room temperature.

2. Fast power consumption with 5G network:
When your phone uses the 5G network, the 4G network is turned on simultaneously, so the power consumption automatically increases. You can turn it on or off according to your needs by going to Settings> Network & Internet> SIMs> Preferred Network Type.

3. Fast power consumption after upgrade:
Power consumption increases after you upgrade your phone. Charge for one night after the upgrade. Alternatively, your phone will recover by itself after 2-3 days of normal use.

4. Check the power consumption details:
Go to Settings> Battery> Battery Usage, and check the power consumption details of corresponding programs.

Please try the following:

1. Open the auto-start Settings page and cancel the auto-run application. Note that some models have no auto-start option.
2. Uninstall any applications that you don't use much.
3. Ensure your phone is updated to the latest firmware version. You can check if updates are available by going to Settings> System> System Update.
4. Back up any important data (such as contacts, text messages, etc.) and restore your phone to factory settings.

Please try the following:

1. Check if your phone has recently downloaded and installed a third-party application. Uninstall it: Settings> Apps> See all Apps> Find the third-party application> Uninstall.
2. Check if the issue is to do with multiple applications running at the same time. Shut down and restart your phone regularly.
3. Back up any important data and restore your phone to factory settings.
4. Ensure your phone is updated to the latest firmware version. You can check if updates are available by going to Settings> System> System Update.

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

Please try the following:

1. Clear all background apps.
2. Restart your phone and try again.
3. Change the network environment or switch to a different WiFi or data network. Ensure the network is stable.

5. If using a third-party music player, install a music player app from a different party, restart your phone and try again.
6. Uninstall and reinstall the player.
7. Ensure your phone's system is the latest.

3. Reduce the game configuration (image quality, resolution, turn-off special effects) and try again.
4. Keep your phone fully charged. If the power saving mode is turned on, turn it off temporarily to enhance performance.
5. Restart your phone and open the game again.
6. Go to the application management to clear the game's cached data and try again. Be sure to back up any important single-player game data as it'll be lost after you clear the cached data.
7. Check if your phone has just been updated. If so, restart and try again.
8. Ensure the game and phone system are updated to the latest version.

Ensure you're in a country or region where call recording is supported. Features vary based on your country or region.

1. Start a recording from a call

The first time you record a call, you’ll be asked to comply with local laws related to recording calls. Many jurisdictions require consent by all parties to record the call.
For privacy protection, when you start recording, both parties are notified with a disclosure that the call is being recorded. When you stop recording, both parties are notified with a disclosure that the call is no longer being recorded.

To record:
- Open the Phone app.
- Make or receive a call.
- Tap Record on the ongoing call screen.
- To stop recording, tap Stop recording.

2. Find a recorded call

Recordings are stored on your device for privacy protection — they aren't saved or backed up off-device.

To find your recording:
- Open the Phone app.
- Tap Recents.
- Tap on the caller you recorded.
> If you recorded the most recent call: go to the player in the Recents screen.
> If you recorded a previous call: tap History. Then select the recording from the list of calls.
- Tap Play.
- Optional: to share a recorded call, tap Share.

Tip:
You can share recorded calls to supported apps, such as email or messaging apps.

Please try the following:

1. Ensure you're in a location with strong network coverage. Closed environments like high-speed rail generally provide poor coverage.
2. Remove or replace the protective case if using a metal one. Plastic or leather ones generally enable better network connection.
3. Replace the SIM card to check if the issue is to do with the SIM card.
4. Ensure you're not exceeding your monthly traffic limit, as this may result in traffic restrictions. Contact your carrier for more information.

Please try the following:

1. Hang up and call again.
2. Change the network environment, especially if there are high-speed moving objects such as high-speed rail or a highway nearby.
4. Reinsert or replace the SIM card.
5. Back up any important data (phone number, SMS, etc.) and restore your phone to factory settings.
6. Ensure the firmware is updated to the latest version.

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