After Bluetooth, device reboot and some other issues, new problems with multiple Sony Xperia smartphones have come to light, with one of them being really serious. Thankfully the company says they will be fixed in upcoming software updates.

To start with, it was a month back when both Xperia X/X Compact users started chiming on the official Xperia Support forum that after a recent update their devices have started to turn on/boot up by themselves.

Specifically, device owners explained that when they plug-in a charger to their unit while it’s turned off (say, to charge it overnight), the device auto turns on shortly after the battery reaches to full, or 100%.

On the face of it, the issue may sound minor, but it’s actually not. In fact, it’s a serious security problem, as users say the behavior causes the phone to get turned on and reach a ready to use state, bypassing the SIM lock screen or encryption password prompt (some users even mention fingerprint security prompt), measures usually in place to strengthen the security of devices against unauthorized access.

As the number of complaints increased, Sony got into action. One of the company’s support staff members addressed the matter in question yesterday, and assured that the next software update will fix the problem on both the devices.

You might experience that the device turns on by itself, when it is connected to a changer and the battery is fully charged. We are aware of the behavior and it will be corrected in the next software release

Coming to the second concern, Xperia XZ Premium users recently brought to notice a permanent ‘WarrantytimeService‘ notification post the Oreo update, that shows up on a dedicated white strip in the notification shade. The notification in question can be seen in the following user shared screenshot

A user also shared a short video clip showing the same. Though the notification text can not be clearly seen, the white strip is clearly there:

Sony officially acknowledged the warranty message issue as well, saying this will also be fixed in an upcoming security update.

After updating your Xperia XZ Premium to Android 8.0 (Oreo), you may notice a notification that reads “WarrantytimeService”. We are aware of this behavior and it will be fixed in an upcoming software release

The Xperia X/X Compact auto turn-on is a pretty serious security issue, so we are expecting a fix for that will be pushed out very soon. In worst case scenario, the next security update should fix both the issues. We’ll update you whenever the fixes are rolled out, so stay in touch.
