need help verifying cpu speed

Hi Everyone
I have OC Widget installed on my phone (htc hero sprint) and I was wondering is there a way to confirm that the speed being reported by OC widget is in fact the actual cpu speed. My reasons for doubting this are that
1) even with a setting 710mhz the phone seems kind of sluggish at times
2) I get notifications of cpu settings changes when turning my screen off to on but I do not see a change in the number displayed in the widget (it is always set at the on screen speed)

adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
*edit*
I would be interested in knowing where you read CPU temperature information, though.

CPU temp huh...i have no idea lol
Since you brought it up I do have a question for you that is somewhat related, can access heat (from either the battery or cpu) cause a reboot (either a complete reboot going through all the load screens or just a reboot to boot back into the home screen).
I was experiencing quite frequent reboots (the later of the two I described above) and had initially thought maybe they were app related but could never determine if that was the cause.
I was over clocking and underclocking so was wondering if maybe that could have lead to some instability issues.

Clock speed and voltage go hand in hand - if you are adjusting one without the other, yes, you will affect stability. Heat also plays a part - now, specifically can a hot battery cause a CPU malfunction? Yes, but unlikely. More likely, the heat will affect the voltage from the battery and case CPU instability via that path.

[Q] Clockspeed stucked at 998mhz

Hi there, I'm on FreeX10 Beta4 with the latest camera hotfix, after patching the hotfix there were twice where I encounter my phone seemed to be stucked at 998mhz full load.
Realized that when my phone heats up all of the sudden. Checked through system panel found nothing was using up the processor but it's at full load on SetCPU its set to scale on-demand. Gotta reboot the phone then it's gone. Anyone had any idea whats going on? It was all fine before I applied the hotfix for the camera. Thanks in advance!
Sorry I've realized I've posted in the wrong section, can any mods move it over to the Q&A, Thanks!
Update: Used google goggles, and my proc is on full load again

Wondering also if anyone had similar problem to that, I can't post a reply on FreeX10's thread regarding this problem due to post count

Since the kernal is still the SE one, setcpu would not work.

Hmmm that is just to check the scaling, but weird thing is that my processor goes up to max when I try to use google goggles, any idea what would be the problem? It just gets stucked at max clockspeed till I reboot my phone

I had this as well, there was some internal process using up most of the CPU all the time (something like xftwd-daemon).
I read that you can fix it by rebooting your phone, and it worked.
Apparently this happens on the first boot after wiping the cache or dalvik cache or something.

Happened a few times even after reboot. Wiped my battery stats and trying out now to see if it's still happening So far so good

j5 heat problems

well my phone cpu is always around 40 - 50 at any clock ( 0.8 to 1.2 ) and this produces a heat around the screen ( the phone is blazing fast and smooth consumes a fair amount of battery ) i 've installed before many roms and this problems started when i first used root booster with 6.0.1 then it presisted with any rom i install even flashing official rom don't change the config
my questions is is those thermals normal ?
can somebody screeshot CPU covernor tunable from kernel auditor
and how can i reset my cpu original setting

You have made similar threads/posts before CPU kernel and settings are reverted to original when you flash a stock rom. During summer, my cpu was between 40-50 and now it is cooler. It depends of what you do with your phone. For example, mobile data - GPS can cause heat to phone.
If you think that something is wrong with your phone, you can bring it to a service... although i dont trust anyone unless i see with my eyes what they do.

i am at minium use and the phone hits up flashed stock rom but the problem is always consistent

Workaround for mmc_read_failed and mmc_write_failed errors

As many others here I started to have mmc_read and mmc_write errors with my N910F plus freezes and restarts or no boot. For me is another case of programmed obsolescence from our beloved Samy as I previously had with the Note 2 chip bug. I supposed that the problem comes from overheating (from a short-circuit or a failing transistor) and I got confirmed. The phone cpu and gpu go up to 90-100deg Celsius. In case you still want to keep your phone and save money until the Note 8 is out here is a possible workaround:
- In case you get mmc errors when flashing with odin you have to take out the battery an keep them both somwhere cool for 15 minutes. Then flash immediatly after starting in download mode, before is heating again.
-If you managed to boot and root you can install Kernel Adiutor or something similar and keep the processors at a max frequency around 1000MHz .
For me it worked and after 2 weeks of testing all kinds roms with repartitioningn, nand erase etc. I have a working if little less performant phone for a week now.
Edit: Device Control is another app that seem more stable and it has a thermal dedicated control over CPUs. Even with intensive use the phone doesn't freeze now. It still needs to be cool to boot.​*I also flashed RamKernel and I don't know it KernelAdiutor works with factory kernel.
Edit2: Wakelock app with level 4 setting > 3 days and going with no lag and no restart. So maybe all above is wrong...

Random reboot N910F

Hello XDA
I have the Note4 N910F, it start to random reboot tow month's ago
i decided to look why is that happen i noticed it reboot when its get hot
i installed the Device Control app it show the CPU temperature 84C° TO 86C° with out doing anything in the device so i decided to UC The max CPU frequency from 2649MHz to 1958MHz the temperature now never across the 75C° and its never reboot anymore
but when i reboot the device it go through the boot process and reboot when the home screen appears i have to cool it with cold air to boot normaly so i can UC the cpu again
why is that happening and is there away to UC the CPU permanently?
by the way its the same on stock firmware and the same on other roms
Thanks XDA

Hello!
I'm afraid that I can't really tell you why this is happening. I strongly think of a hardware issue.
But I think I know a way how to prevent your phone from overheating while booting. You mentioned the Device Control app on your post, so let's start with my first suggestion:
Is there an option in the app like "apply settings on boot" or anything like that? If yes, try to enable this option and reboot your device to proof if it worked.
If Device Control does not support this feature, I recommend you Kernel Adiutor. I used it for over one year and also used the "apply settings on boot" option that worked like a charm for me. It's basically the same application, just with another design, another name and so on, but practically it does the same.

Hello
Thank you for respond
The Device Control doesn't have Apply On Boot so I used the Kernel Adiutor You recommend
It do have Apply On Boot and i switched it on but It didn't make a different because it apply the setting after the boot process complete not before or during the boot process
you mentioned a great app thank you for that, the thermal option is useful it turn of cores if the CPU Temperature Get higher than a temperature i chose which i set to 50C°
i will learn to live with the (Cooling during booting) what really bothering me is the rebooting when i am on the middle of a call or working or playing on the phone
now it's solved with Kernel Adiutor
here is a picture of the CPU and GPU temperature before changing frequency and setting the thermal control
seconds after booting
______
and this after make changes
Thank you

You're welcome!
At least I was able to help regarding the phone's random reboots due its heat development while using it.
I something comes to my mind that could help with preventing the phone from overheating while booting, I'll let you know.
But for now, I'm happy you can use your phone under normal conditions again. Have a nice day!

It's almost normal it just have fever hope it'll recover soon
You have a nice day too
