It's happening to me too... When I use my gnex a lot or watching a video or playing a game it turns hot the top part of my screen. It usually happens when I have low battery or when I use it while charging. Does anyone know why this happens?

Its where the cpu is located. So you are probably using cpu intensive applications. Try to undervolt or underclock to keep it cooler.

What are the safest/recommended levels to undervolt in trickster mod and should each MPU level be tweaked individually OR is it OK/better to adjust all MPU levels by a certain degree?

Well manual undervolt induvidually is the best of course. But it takes very very long.. I always undervolt -50 for all the mpu voltages. See if -75 works but not a lot of gnexus can do that.

Maybe there is a sneaky app thats using up your cpu. But mine gets hot when browsing 9gag and that sort of stuff. This device is old.. Maybe check cpu usage by enabling it in developer options.

Its in the devlopment section. But I suggest using a newer kernel because franco is not longer supporting the galaxy nexus. Maybe try dirtyv, its pretty populair.

Thanks, -75 seems to be working so far.

I just hope there's no long term downside/side-effects from undervolting.

There are no downsides. In fact it extends the life span of your cpu. Only undervolting too much will cause instability. So just check. Maybe do some sort of torture test..

Well, phone started to keep rebooting after playing real racing 3 for a couple of mins.

Luckily had a 5 sec window to uninstall trickster mod before undervolting settings were applied.

Going to try -50 this evening, I need a functioning phone during work time.
LOL

-50 undervolting levels are holding up to the pressure better so far.

I definitely noticed the screen not getting as hot now when gaming and battery life has "slightly" improved.
