OPPO K7 supports VOOC 4.0 flash charging technology. When the device is being charged using VOOC 4.0 flash charge, the charging icon is usually orange or amber. This means that your phone is using the flash charge feature to charge quickly.

It should be noted that the color and style of the charging icon may vary depending on the phone's system version and Settings. If you can't see the flash charge logo, make sure your charger and charging cable support VOOC 4.0 flash charge. Also, check your phone's system and Settings to make sure the flash charge function is not disabled.

If your OPPO K7 is charging with VOOC 4.0 flash charge and you find that the charging speed is slow or there is no flash charge sign, it may be due to the following reasons:
< br >
1. Non-original charger or charging cable: Using a non-OPPO original charger or charging cable may not support VOOC 4.0 flash charging. Use the original charger and cable for charging.
2. Charging environment: The temperature is too low or too high may affect the flash charging function. Make sure your phone is charged at the right temperature.
3. Battery aging: Aging batteries may slow down charging. If your phone has been used for a long time, the battery may have aged and needs to be replaced.
4. Software problem: The system or Settings of the mobile phone may be faulty, resulting in the failure to enable the flash charge function. Please try restarting the phone or updating the phone system.
