new discovery about the screen upside down's problem

---

well this is my first thread here. i just want share something here and if my bad english can't express what I mean and make some guys not happy sorry about that....

ok let's back to the topic.i have met much more srceen upside down's problem in different rom with different kernel and want solve the problem but cannot becase of my limited skills. but today i find a the min cpu frequency will make the sreen different.

that is:
if i chose the min cpu frequency at 192 MHz and meet the screen upside down very frequently.
the default min cpu frequency is 268 MHz and meet the screen upside down often.
if i chose the min cpu frequency at 345 MHz and meet the screen upside down very few times.
if i chose the min cpu frequency at 1036 MHz and cant meet the screen upside down

test like this:
chose different min cpu frequency and close the screen then open the screen then close then open..

the roms i have tested have the same phenomenon
PACman_GLACIER v16.1
SyNthetic_aospX 1.0.0-MR1SG

well that's all
i know that may really not solve the problem just share it with you guys.

I think it also has something to do with the governors too. I could use the same frequency on smartass v2 and performance but it happens less often on performance.

thx for reply. feel better at 345mhz with v2

I can get the screen to flip regardless of frequency unless I switch to the performance governor. Then a max frequency of 384 still flips easily, but 784 and above is better.

Performance maxes out the cpu at all times, which helps the OP's point.

i feel min frequency of 384 may help not max frequency
