I have an ifinix hot 3 X554, the phone starts up and the phone's logo appear then the screen goes black
The weird thing is that the phone rings when someone tries to send me a message or contact me but the screen still black
Try starting it up in "Safe Mode" and see if it will show the screen. If it does, then there is something on the phone causing the problem. Bad app, virus, malware, etc., which you would need to then remove.
To get into "Safe Mode" please do the following.
1. First turn off the phone.
2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.
3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message "Safe mode: ON" or something similar.
4. If you wanted disable it, simply repeat the steps above, and you should see "Safe Mode: OFF" rather than on.
