Sony Mobile’s new Xperia flagship, Xperia 5 II.
The DoCoMo version has been released in Japan, and it seems to be the most popular at least for Android high-end models.
Although it is such an Xperia 5 II, there have been reports of problems that are a little worrisome overseas.
The lock screen does not appear immediately after pressing the power button
As soon as it came back up, I noticed immediately that when the screen is off and I press the power button (I don’t use a fingerprint to unlock, rather I use the pin unlock), there’s a consistent 3 or 4 second delay
In shortThe screen does not turn on (lock screen is displayed) immediately after pressing the power button, and it takes 3 to 4 seconds to be displayed., The symptom.
There are reports that the same symptom is occurring on the Xperia 1 II on the same thread.
This was often reported on Android smartphones a long time ago.“Petit sleep death”It seems that the symptom corresponds to.
In addition, this user does not use unlocking by fingerprint authentication, but uses pin unlocking.
In any case, it is said that the symptom will occur even with fingerprint authentication, pin unlocking, and unlocking, so at leastNot a problem around fingerprint authenticationCertainly.
Is the cause of petit sleep death “double tap to wake up from sleep”?
On the other hand, when I was looking for a similar symptom, this problem was a feature that was revived from Xperia several generations ago,It tends to occur when “Tap to show lock screen” is turned on.I found the information.
・Settings → System → Operation
・ Turn off “Tap to show lock screen” at the bottom
On the other hand, there are reports that this symptom is likely to occur when the developer option is enabled on Reddit.
In addition, there is a report that if the same symptom occurs, it was improved by turning off the power and inserting and removing the SIM card and microSD card.
By the way, a long time ago, there were multiple reports of problems that the fingerprint sensor did not respond at all on the Xperia 5 II.
This is a symptom that the authentication process itself is not performed, not that the authentication fails, and it seems to be related to this Petit Sleep death.
