1. Unable to start the phone due to machine brushing: If you encounter that Xiaomi mobile phone cannot start the phone and stays on the MIUI interface during machine brushing or other playing, it may be caused by the failure of machine brushing operation.In this case, you can try to reboot the phone or reset the phone after clearing the user data.It should be noted that the brushing process may take a long time (about 3-5 minutes), so please be patient.
2. Unable to start the phone after automatic shutdown without charging for a long time: when the phone prompts that the battery is insufficient, if the phone continues to use without charging in time, the phone may fail to start.Most of these problems are related to the battery. The solution is to take out the battery and use the charger to charge it for several hours, then reinstall the battery and try to start the machine.
In addition to the above situations, please ensure that the ambient temperature of the phone is appropriate, and avoid the impact of too low or too high temperature on the device.If the problem still exists, please consider contacting after-sales service or professional technicians for further troubleshooting and repair.
A cross at the top right corner of Xiaomi's mobile phone indicates that the mobile phone has turned on the Volte switch, but the Volte service has not yet been turned on.The X symbol in the upper right corner of the phone indicates that you missed a call and did not receive a call.You can see the specific number in the phone. Sometimes many harassing calls ring in the missed calls list, and missed calls are also displayed.The reason and solution for the failure of Xiaomi's mobile phone to start up: it is unable to start up due to the failure of the machine to stay in the MIUI interface. In the case of the machine to be cleaned or other games, it will be impossible for Xiaomi's mobile phone to start up. It will take a long time to restart after the machine has been cleaned up or the user data has been cleared, about 3 to 5 minutes.So many users don't try to wait when they ask this question.Do not rush to restart the machine or play other things, clear data, etc.After a long time of non charging, the phone can't be started automatically after it is turned off. When the phone prompts that there is no power, it is not charged in time, which leads to the phone can't be started after it is turned off. Most of these reasons are caused by the battery. The solution is to unplug the battery and charge it with the charger for a few hours before installing the battery to start up.Or try another battery.
In this case, there is no signal, and there are two states.
1： Your location is remote, and the operator's network cannot cover it.
2： There is a problem with your mobile phone settings. For example, if your mobile phone is a telecom card for Unicom's 3g mobile phone, if you set it to 3g network, there will be no signal. You can try to see if there is any of the above, and hope it can help you.
