The veteran here will remember a very useful feature – which wasn’t even considered as such – that cell phones had from yesterday but that we lost after the arrival of smartphones. And it’s that before smartphones arrive Telephones could trigger the alarm even if the terminal was switched off. But, Does this feature work on Android?
Yes and no. The answer depends on each device because although it’s true that The alarm cannot be triggered if the smartphone is switched off Since the operating system alone cannot “wake up” the device without user interaction, some manufacturers offer an option that enables this Switch on the device a few minutes beforehand the time the alarm is set.
Can the alarm go off when the mobile phone is switched off?
Whether this function is included in a terminal or not does not depend on the manufacturer, but on the processor integrated in the smartphone. For example, Most terminals with a MediaTek chip integrate a programmed phone startthat can be activated when configuring the alarm so that you do not miss it even when the terminal is switched off.
On the other hand, Some devices with a Qualcomm processor B. those from OnePlus or those of the Spanish company BQ, also contain an option of this type that enables this Program the automatic switching on and off of the terminal at a time predefined by the user.
So in the end We were able to confirm that no: the alarm does not sound when the mobile phone is switched offAlthough it is possible – as long as the device manufacturer has implemented it – to switch the device on a few minutes before the sound using an automatic on / off switch.
