If you notice that your Doopro P1 Pro hangs, stays frozen or "thinking" for a long time, it does not react, perhaps because it is overloaded and you have thought about restarting quickly to free up its RAM memory, in just three steps we will indicate you how to restart it.
A restart does not erase any data, it only consists of turning the device off and on again, if you want to erase all the content and restore the factory, consult the following tutorial: How to restore a Doopro P1 Pro.
Before restarting, you must bear in mind that you must know the PIN code of the SIM card and the unlock pattern or password of the P1 Pro, since it will request it when it is turned on again.
Estimated time: 2 minutes.
1- First step:
Press and hold the power or unlock button on the Doopro P1 Pro until a screen with various options appears.
2- Second step:
Among the options that are displayed on the screen of the Doopro P1 Pro we choose "Restart". If a confirmation message appears, press accept.
3- Third step:
The device will turn off and on again to perform the reboot, wait a few seconds or minutes. When it is turned on again, it will request the PIN code of the SIM card and the pattern, fingerprint or unlock code.
If you cannot restart the Doopro P1 Pro since it is blocked and the previous method does not work, we must proceed to turn it off and turn it on again using the physical buttons.
To force a shutdown on your P1 Pro press and hold the power button (or unlock button) for at least 8 seconds until the Doopro or Android logo appears on the screen and release the button while it turns on again.
If the device still does not respond and you cannot restart it, it is possible that it is low on enough battery, in that case connect the P1 Pro to its charger and try the procedure again.
If it continues without responding and does not turn on or has entered a loop, it is possible that some internal component such as the motherboard, memory, screen or even the power button has been damaged so you will have to repair it or resort to the warranty.
