Re: Nougat upgrade lowered cpuclock??!

All cores are active. "busybox mpstat" shows activity for all of them:

So the bug must be in those monitoring apps in Nougat. The cores 4&5 are up and running!

Exactly the same on my Xperia XZ running nougat, restarting the phone makes all cores run again at maximum speed but as soon as you turn off the display it stops 2 cores permanently

As said two post berfore, this isn't true.

The A72 core are active but wrongly shown as stopped. No problem with bench or games except some which have problem with nougat in general.

There is nothing wrong with the phones, the problem lies with the poor implementation of nougat coding in their apps.
Download multi core monitor from Google play and you'll see the cores all working fine.
