The Black Shark 6 Pro is known for its advanced gaming capabilities and its fast side fingerprint sensor. However, some users find that this sensor becomes temporarily inoperative after intensive gaming sessions, such as Call of Duty Mobile or Genshin Impact.
When the side fingerprint stops responding
The blockage usually occurs during or just after intensive use, when the phone is heavily taxed by resource-intensive games.
The effects of overheating
During a prolonged session, the processor and GPU generate a lot of heat. The side fingerprint sensor may pause to prevent failure, as high temperatures can affect the accuracy of the touch reading.
It is therefore not a defect of the sensor, but an internal preventive measure to protect the system.
The influence of the GPU and RAM
When the game heavily uses the GPU and occupies a significant portion of the RAM, the system may prioritize resources towards graphic rendering, resulting in a temporary delay of the fingerprint sensor.
In some cases, the fingerprint remains blocked for a few seconds or minutes, then becomes functional again when the processor load decreases.
Checks before any intervention
Before considering complex solutions, some simple checks can confirm the cause and avoid unnecessary manipulations.
Restart the phone after an intensive session
A quick restart can reset the sensor and system memory, allowing the side fingerprint to work again.
Testing the sensor after the restart can determine if the blockage was related to a temporary overload or a hardware issue.
Update the system and applications
Software updates can fix anomalies related to the sensor. Installing the latest version of JoyUI or MIUI for Black Shark, as well as game updates, can improve the stability of the sensor during and after gaming sessions.
Solutions to reduce blockages
Some methods can limit the likelihood of the sensor being temporarily blocked after an intensive session.
Avoid overheating the phone
Placing the Black Shark 6 Pro on a ventilated surface, removing the case, or using an external fan for mobile gaming can reduce the smartphone’s temperature.
A decrease in heat improves the sensor’s responsiveness and reduces interruptions related to thermal overload.
Limit background applications
Closing unused applications before launching an intensive game can reduce the load on the RAM and processor, which reduces the likelihood of the sensor temporarily blocking.
This allows the system to manage resources more smoothly, even during long sessions.
Check the sensor settings
Sometimes, the fingerprint sensor can be temporarily disabled by certain security options or game modes. It is advisable to check the side fingerprint and Shark Space mode settings to ensure that no restrictions are active during the game.
Additional solutions
If the previous methods do not yield results, other actions can help restore the sensor’s functionality.
Use another unlocking mode temporarily
If the sensor remains blocked after several attempts, switching to a PIN or temporary password allows access to the phone without waiting for the sensor to reactivate.
This solution offers a quick and secure alternative while the system cools down.
Contact Black Shark support
If the problem persists despite all checks, it may be a hardware anomaly or sensor failure. Contacting official Black Shark support allows for diagnosing the device and, if necessary, obtaining a replacement or repair under warranty.
It is not recommended to disassemble the phone yourself, to avoid voiding the manufacturer’s warranty.
