I inadvertently depressed, I think the on/off button whilst picking up my phone this morning & the screen looked as if it was goign to reboot/restart but it has stayed frozen in that screen (Fairphone Change is in Your Hands screen) with a blue light in the upper corner.
Is this one when you just have to take the battery out for a moment & reinput? I’ve tried holding down the power button to see if I could kick start it into action but to no avail.
You might need to hold the power button longer – it takes like 12 seconds until it forces a reboot.
What you ended up in is called the “fastboot mode” (the blue LED is a clear sign for that) which is triggered when you keep holding the combination of the POWER (on/off) and VOLUME DOWN buttons.
