Sony Xperia 10II - Low power mode

[spiiroin]

Firstly from 3.2.0 / Torronsuo release notes:

An attempt was made to prevent calls from being accidentally held [Xperia X devices]. Proximity sensor utilization was tweaked to improve the reliability of in-call blanking behaviour. Unfortunately, this change also affects the Sneak Peek feature. Those users who have not experienced problems with in-call proximity blanking and wish to continue using Sneak Peek can revert back to the previous behaviour by executing mcetool --set-ps-on-demand=disabled from the command line.

Basically: In Xperia X the above should make lpm work without causing any issues. In other Xperia devices there is some risk that proximity sensor will start misbehaving and cause issues both for lpm and in-call proximity blanking.

I experience the same effect on my Xperia X; the lpm timeout is effectively one second regardless of the setting of --set-blank-from-lpm-on-timeout. This has worked on SFOS3 but seems to be broken with SFOS4. It would be great if this could be fixed somehow.

There was a change in topmost window reporting (AFAIK in 4.1.x release) and this caused some more or less subtle problems for fingerprint wakeup, blanking timers, …, and lpm (misinterpreting topmost window state makes it look like there is an app on top of lpm screen = not ok for lpm → lpm is canceled → display blanks). Fix is in 4.2.x. Some more info at: [BUG][4.1.0.23, 4.1.0.24] Unlock device by fingerprint
