btw, I hope that power-save mode is disabled, else you'll find lag more often than not.

other reasons may be unscrupulous apps that run in bkg monitoring your phone and consuming ram and cpu cycles in general.
[Galaxy Note II Q&A, Help & Troubleshooting] LocutusEstBorg:
This has nothing to do with input lag, only UI framerate.
[Galaxy Note II Q&A, Help & Troubleshooting] UltimateByte:
EDIT

SO, we know how much input lag is from touchscreen, about 100ms, the question is : how much can we reduce that ?

We also know that

1- Frame buffering (pre render frames)

2- Vsync

3- Hardware treatment (pentile ? color managing ? hardware chip ?) => this part can't be improved

are not such issues compared to the touchscreen.

Sorry but you didn't understand the problem. We're not stupid, and for sure nobody uses this damn power save mode, and I personally tried with several ROMs, and several wipes, so no background stuff possible. Also, it's not a problem of laggy stuff or CPU used, or full RAM, it's an input lag problem, the time the phone takes to manage your actions and display it, even if it's perfectly smooth.
[Galaxy Note II Q&A, Help & Troubleshooting] LocutusEstBorg:
No his test shows it IS the touchscreen. He said the DIFFERENCE between the mouse and touchscreen was 100ms. That 100ms is 100% from the touchscreen. It's unlikely that everything else is more than 5ms in total with the worst case vSync being 16ms.
[Galaxy Note II Q&A, Help & Troubleshooting] UltimateByte:
OMG, i didn't understand the right way...

This is insane ! This is even more than i could expect for the touchscreen !

So as you seem to know what you're talking about, how much do you think we can imrpove that by software tweak ?
[Galaxy Note II Q&A, Help & Troubleshooting] Chrissssssss:
Like I said it's not a very scientific test with so many variables including my reaction times, but consistently the touchscreen did seem to show a reaction time somewhere from 80-100ms slower than my wired mouse connected with the OTG cable.
[Galaxy Note II Q&A, Help & Troubleshooting] UltimateByte:
That's good enough for me, i tried a reaction test, i'm always between 0.294s and 0.315s, so if i had a way to connect a mouse, would be easy to know how much time the touchscreen takes as you did.

Edit : Well with some training i hit 271 to 294ms :o)) I wish i had a USB adapater to connect a mouse and test it too, i may try to find one.

[Galaxy Note II Q&A, Help & Troubleshooting] LocutusEstBorg:
Even Samsung cannot do it. In some other thread the Samsung engineers told someone that even they simply receive just the firmware blobs for the touchscreen from Amtel. The only thing that has been achieved so far on the touchscreen device is changing the Vitalij value via sysfs on the SGS2. You can look through /sys/bus/i2c/devices/3-004a/ or /sys/devices/platform/s3c2440-i2c.3/i2c-3/3-004a/ if they exist on your device.
[Galaxy Note II Q&A, Help & Troubleshooting] UltimateByte:
Thanks for trying to help.

I made a topic.

I don't have a 3-004a folder in the platforms, only a 3-0048 one. Maybe cause i'm now running P.A.C. ROM ?

Same in the second one, only a 3-0048 folder.

So you think it would be a good start for tweaking ? I'm not a programmer, but maybe we could ask in my topic... ?

Hey guys , I', having a problem powering on my Droid.Almost every time I try and turn it on , the Backlight of the screen will come on for a few seconds then shut off. I then need to take the battery out etc just to make it do that again. Then every once in awhile after a few minutes of playing with it , I would finally get to the Dual core screen. Now this has only been happening since I installed safestrap V3 , I was fine with all the previous safestraps. But now , even after a reflash , it does this. Any suggestions?

Good Day, I'm hoping someone can help me, I've tried searching but I can't seem to find anything(mainly because I don't know the best way to describe it) sometimes, randomly the screen will turn off, as it should but then it wont come back on, I've installed the wake on volume mod and that doesn't seem to help.

Happened with CM7 and now with The darkside rom.

It's sporatic, it wont do it for like 10 hours then will do it 3 times in an hour.

Any help would be greatly appreciated

Thanks

[Atrix 4G Q&A, Help & Troubleshooting] jjmrchbnks:
I have a similar problem. But mine only happens when i make or recieve a call, doesn't do it everytime. I actually found a thread where it said it was possibly a broken proximity sensor. So the solution was to download 2 things from the app store and install them, and disable the proximity sensor. I am going to try that, cause when i make or recieve a call I actually turn my screen off so i won't hang up on anyone or hit several buttons. The solution they gave was to have a rooted phone, and download "android sensor box" so you can see the name of your proximity sensor, and then download "hardware disabler". Find the name of your proximity sensor and disable it. I have tried everything else, so what do I have to lose on trying this, lol.

My wife is looking to upgrade her Motorola Atrix, we are currently on Straight Talk in the U.S. (AT+T sim) and love it for the value. But it seems like ALL of the new, fast phones are too large for her, so I'm very interested in the Razr i.

Has anyone purchased a Razr i and is using it on Straight Talk? I'm not looking to tinker with it at all, so I'm curious if it's as simple as popping a Straight Talk sim in the phone. Are there are any limitations on using the phone on Straight Talk (any data speed limits, do you get HSPA+ speeds, etc.). Thanks for any info!

[Kindle Fire Q&A, Help & Troubleshooting] 24861:
I cannot seem to get my kindle fire unbricked despite reading and trying all solutions I could find and/or think of. I've tried KFU, Kindle Fire Debricker/Unbricker, followed various tutorials, and even made my own factory cable all to no avail yet. My Kindle simply keeps rebooting itself into the stock OS 6.3.1 of amazons about every 30 seconds +/-. Nothing I do can/will change that. When it starts up it shows the kindle fire bootloader then onto the main "Home" screen where various notices come up stating that basically everything is NOT working and they've all failed miserably and horribly. Then onto the next reboot. There is no longer any sort of recovery as far as I can tell. I cant get it to respond to any sort of fastboot anythings. On the positive side I do have the drivers loaded and can use adb with it at will, including adb shell. But all that is just about pointless as any command I try and enter, it simply responds with something about me not having any rights to do anything. I'm pretty sure I know what happened, far as I can tell I was in TWRP recovery when I tried to flash the stock firmware from there and everything just failed. Anyhow, if anyone has any idea what so ever on what to try or where to look for an answer, I'd be eternally grateful. Or if any other info is wanted, just let me know. Thanks all for any advice given ahead of time.

[Kindle Fire Q&A, Help & Troubleshooting] 24861:
Not to be rude, but..... Any chance on any actual help? Like maybe what to do? mLike I previously said I already have a factory cable but have gotten no where with that. Thank you
[Kindle Fire Q&A, Help & Troubleshooting] soupmagnet:
Sure, but I need to know a few things first...

Do you understand what the factory cable is for? Do you know how to use it?

Do you know what fastboot is and how to use it? If so, do you know how to use it to install recovery?

Do you have a general idea of what you need to accomplish to fix your KF? (see the link provided)

"That's a special kind of stupid. The kind that makes me laugh"
[Kindle Fire Q&A, Help & Troubleshooting] 24861:
In general....... yes.

Factory cable is simply to put it in fastboot (although I dont know that it does on mine).

I do know what fastboot is and can type in the needed commands if you'd be willing to tell me, though I know a couple.

And yes, Im looking to install TWRP and then flash a stock rom and stock recovery.... I believe.

Then again, all that is probably wrong, ergo why I ask you sir.

Thank you
[Kindle Fire Q&A, Help & Troubleshooting] soupmagnet:
Okay...

When you plug your

powered off

Kinlde Fire into the computer with the factory able, it should boot directly to fastboot. Meaning, it will stay at a bright Kindle Fire logo and not go dim or flash.

Anything outside of that would make me wonder if your factory cable is defective (probably not likely) or your battery is near dead. The 30 second reboot is a good indicator of the latter, although that particular situation usually results in a much faster reboot loop (5-10 seconds).

Plug your device into your stock charger and immediately hold the power button down until it shuts off. Then let it charge for a while then try again later.
[Kindle Fire Q&A, Help & Troubleshooting] 24861:
Okay. So far so good. Is doing just what you said, except for I evidently have no fastboot driver installed. Plus it doesnt recognize that the fire is plugged in (in fastboot mode) inside the device manager. So....? Is there a specific driver (fastboot driver) that I need to load (and do you have it?) and how do I get the fire to atleast become recognized?

Thanks again bud
[Kindle Fire Q&A, Help & Troubleshooting] soupmagnet:
That may not necessarily be the case. What color is your Kindle Fire logo?

"That's a special kind of stupid. The kind that makes me laugh"
[Kindle Fire Q&A, Help & Troubleshooting] 24861:
Its white and orange. Although I believe my current issue is that it is stuck in fastboot (4002) mode. Even though it still reboots into normal mode, it remains stuck in fastboot. And I am unsure as to how to get it back as nothing will recognize it, so no drivers will ever install. So I am currently trying to let it run dry of juice in hopes it will reset when its dead. Any ideas?
[Kindle Fire Q&A, Help & Troubleshooting] soupmagnet:
Don't let the battery die!

I'll tell you what you need to do later when I have more time. In the meantime, keep it turned off.

[Kindle Fire Q&A, Help & Troubleshooting] Thepooch:
Draining Is never a good idea. It`s very common for the stock bootloader to be difficult to detect even more so now after there recent update in the past few months, because Amazon tampered with the bootloader enough to cause some people issues.
[Kindle Fire Q&A, Help & Troubleshooting] 24861:
okay. Waiting on you. Thanks
[Kindle Fire Q&A, Help & Troubleshooting] 24861:
Just had stock bootloader drivers all installed and what not before I started in with the factory cable (thereby putting it in fastboot (4002) mode.
[Kindle Fire Q&A, Help & Troubleshooting] Thepooch:
Agreed it`s still normal to be undetected by kfu how does it show in device manager?
[Kindle Fire Q&A, Help & Troubleshooting] soupmagnet:
So far everything seems to be working the way it's supposed to.

Using the factory cable to get into fastboot, type the following command and hit enter:

fastboot getvar product

When you see "waiting for device", hold the power button to turn the device off. Unplug then replug the factory cable to boot the device back into fastboot. When it boots, you should see an output of "kindle" in the command window.

If that works, do the same thing for the commands to install recovery and change the bootmode.

If you really want to go back to stock, do what you did previously, only this time be sure to do a "factory reset" before installing the update.zip.

[Kindle Fire Q&A, Help & Troubleshooting] Thepooch:
well if adb is working your not in fastboot adb and fastboot don`t work together it`s one or the other not both. You can access shell but you get permission denied which still could be a broken shell if if you can access the shell. In device manager under Android phone expand that, how does the driver read and in properties what is the hardware id?
[Kindle Fire Q&A, Help & Troubleshooting] 24861:
It no longer registers under "Android Phone" as I input the amazon address into the Android SDK manager to have all the different "ACTUAL" Amazon Kindle Fire drivers be downloadable. Which I did. and now performs FLAWLESSLY. And as far as what your looking for, when I bring up device manager it now lists under Kindle Fire. Driver is Android Composite ADB Interface and the driver date is 12/3/2012 and version 1.2.0.0

Thx Pooch

P.S. - I think it registers under "Disk Drives" and under "Portable Devices" at the same time now as well as its own "Kindle Fire" categories. Just fyi........ if that helps.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] BMXJeff:
So it's been complained about a few times that you cannot sync wirelessly without being plugged into ac power with a WIRE. I want real wireless sync on demand. Why? Why not. My friend with his fruit branded device can and my HD2 is better than that.

Yes I know.....

power conscious OS

you're within range of WiFi and therefore ac power

leave it overnight

Other MS branded noise

No.

I want wireless sync without having to plug in and preferably without waiting 10 mins. I just got home and I don't care if it annihilates the remainder of my battery because with WP7 OS my battery still has days of charge left anyway.

Ok, let's cut to the chase. I have been searching for a while with no luck; I cannot find anybody who has come up with a fix or a workaround to get my HD2 to sync wirelessly without being plugged into ac power. I do not know enough to make a fancy app to allow my phone to do this but am willing to bet there is some way to trick the OS into thinking it is plugged in to ac power so it will begin to wirelessly sync after 10 mins. It would be nice to skip the 10 minute wait as presumably this is just controlled by a 'plugged in' timer and 'sync enable' switch of sorts but one step at a time. Now I know this is a bit of a 'duct tape' workaround but if it works, it works. So my question is this:

:confused: Is there, that anybody knows of, a switch or registry setting to tell the phone it is on ac power, or that it can enable wireless sync (as would be switched on by the OS once plugged in for 10 mins). I think you can see where I'm going with this so any other information regarding USB trickery or fooling sensors/software etc would be welcomed.

In summary: How does the OS/HD2 know it's plugged in?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] BMXJeff:
Having a really hard time getting anywhere with this, especially seeing as I cant even get my wireless sync working while plugged into ac power as it should do according to MS. Followed all MS guides/troubleshooting and nothing happens even after waiting the 10/15/30 mins, all settings double checked and reset. After reading a lot of feedback it seems like a very hit and miss feature.

As for the manual wireless sync WITHOUT being plugged into a charger I've found very little but I'm looking at all possible solutions. Here are my clues so far:

The Zune HD DOES have true wireless sync capability (not charging) with the option to manually initiate it. There could be something to learn there if I had a Zune HD :rolleyes:

Several sources claim WP7 sends IGMP packet data to initiate the connection to the Zune software. I want to look into the possibility of replicating this data to manually initiate the sync.

I have found no obvious switches in the registry that could be of any use. The only Zune related entry that showed any activity when performing a sync (over cable) was "znetsyncstate (0)" ((1) when Zune connected via cable). This is probably just a flag to prevent other apps interfering with Zune's progress while performing sync.

I said that faking the phone being on charge would be an option but I don't have a clue how to do that. I wonder if it would be possible to create a replacement USB driver "serialusbfn.dll" which fakes the charging state which could be switched using an app similar to the USB video app. Very clunky I know.

I read on XDA a guy had created an external battery pack that could be connected to the HD2 via USB to charge the phone at either 500mA or 900mA to replicate both PC USB and AC Power adapter charge respectively. He discovered you could replicate the charging state by splicing certain wires in an old USB lead plugged into the phone. Obviously this would be a horrible hardware hack and not a feasible solution but interesting, nonetheless.

Interesting stuff here about Zune network detection and awareness which could be useful if creating an app to initiate the sync but no methods regarding the sync process that I can see.

My next step is to monitor network packets while the wireless sync takes place so I can see what WP7 and Zune are doing if I can get wireless sync to work at all :mad:

Anybody know anything about modifying USB drivers/DLLs that could help?

Also anybody know of issues with Zune wireless sync on WP7.8/HD2? Be nice to hear somebody has it working and I'm not wasting my time! ROM I'm using in my sig

Ah, I USED prs rom (its cooked rom based on pdaimatejam rom and im using pdaimatejam 8.7 ) and worked well. Exactly after 10 minute my hd started wireless sync but i can't remember that Zune software were running on my computer....
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] BMXJeff:
Thanks for the info, it's helpful to know that it is at least possible. I have still had no luck getting it to wireless sync with Dynamics HD2O 2.00b WP7.8 8858 ROM and I'm not getting much feedback regarding the wireless sync on that ROM thread. I'm loving the ROM too much to change just yet, so I may have to accept wireless sync doesn't like this ROM and put this project on the back burner until I switch ROMs.

I'll do some hunting and see what I can find on that tweak app you mentioned. If I can find it, it will be a great start!

[Galaxy S II Q&A, Help & Troubleshooting] Dampierre:
Hi,

The new games started to demand more cpu and games like Modern Combat 4 lags as hell when cpu is 800 mhz, when it is 1.2 ghz the game is smooth. I am experiencing this problem on a few more games.

I installed an app that shows cpu temp, when cpu reaches 65 celcius, it downclocks to 800 mhz, when it becames 60 celcius, it becomes 1.2 ghz again, and this problem makes major lags. The problem is the phone reached 65 celcius not more than 1 minute and impossible to play without lag. Undervolting is not a solution and my gpu is at stock speed and voltages.

Is there any solution to lock it to 1.2 ghz. Even I set the cpu to performance governor or set the min scaling speed to 1.2 ghz, it still downclocks to 800 mhz. I think increasing the throttling threshold to 80 celcius or sth should solve the situation.
[Galaxy S II Q&A, Help & Troubleshooting] 1Chef:
Use an app like setcpu(https://play.google.com/store/apps/details?id=com.mhuang.overclocking) you need root but you can just set up a profile that if modern combat 4 is running then min CPU=1200 and max= 1200
