Why does my nexus 7 screen doesn't turn on when I'm copying a file to USB stick through otg cable?
Which app are you using to transfer files ? , I am using stick mount which works very well and transfers files in background and I am able to use device,

I have used stickmount, USB otg helper and also native otg in custom roms. while transferring files by solid explorer or root explorer once I turn off screen I can't turn it on again until the transfer is complete
I've noticed this too.
I'm not sure if is completely blocked out (until completion), or just horrendously slow responding to interrupts generated by screen touches/button presses. I seem to remember waking the screen up - after a huge delay - on a multi-minute data transfer.
While it is annoying, it really doesn't surprise me much; most modern OS'es seem like their UIs slow down to a crawl under heavy I/O pressure between slow mass storage devices.
I suppose one cruddy workaround is to turn off the screen timeout ahead of the long copy operation...

If it we're so then it would slow down even when the screen was on instead becoming unresponsive the instant screen was turned off

Yeah ... maybe. I'm not sure. In the past, I experienced difficulty in waking other android devices that had low OC minimum frequencies that would otherwise behave just fine so long as the screen stayed on. I don't know if interrupts start to stack up, or what, but I suspect that the rate governor behavior affects this, and I wouldn't be at all surprised to find out that a screen-off condition figures into the hueristics used by some rate governors or even kernel PM (power management) code. But that's speculation - I don't know.
I guess you could look at this as a feature rather than a bug - if you are performing a long copy, tapping on the power button tells you if it is done!
I am using file manager HD which works well in copying , although there is a 1-2 second delay in unlocking screen when copying, but still it works fine

Firstly hello to all my fellow Vega UK users!
For the price I think this device is great, but it does have it's issues.
Do any of you have the problem where the touch screen just seems to stop working? It'll kick in again soon enough, but it's frustrating as hell.
Also sometimes the task manager seems to appear by itself, but I can;t get it to appear when I need it?
I'm using Pauls Add-on ROM. (thanks Paul )
Logicalstep
I havn't had any major lag at all.
What do you mean by task manager? do you mean the one when you hold "home"?
I have found after a lot of use, with a lot of apps open that the system can lag. I guess this is due to system resources. Recommend installing ES Task Manager from the market to manage running tasks.
You mentioned the task manager appears by its self, do you mean the home screen selector? I found hitting the home button to many times makes this display.
Some users have reported issues with the touch system when the tablet is charging. Do these issues only appear when plugged in?

Yes believe so. due to non regulated power supply causes the screen to become over sensitive.
I get this issue too occasionally, vastly increased when plugged in, now and then when not.
I dont use the machine when its charging.
No real rhyme or reason to it occouring in my experience, id love to know of a cause, other than dirty screen.

Yeah It's a bit of a strange one tbh.
Can;t say I have noticed the lag more when plugged in. I though the PSU was regulated, isn't it just a standard Switch mode PSU?
On the task manager, well obviously there is a task manager with Foryo and oon my Galaxy s I hold the hold button down and it appears, however there doesn;t appear to be a reliable way to do this on the Vega....or am I wrong?
Logicalstep
I never get any touch lag, but I'm not convinced "lag" is the word you want.
"lag" would indicate that the response is somewhat behind the touch action. Android versions below Gingerbread do suffer from that when the CPU is loaded but the Vega is better then most in that regard.
What it does suffer from a _lot_ it erroneous and missing touch events (especially when using a poorly smoothed PSU like the one provided) symptoms include:
1. Swipe gestures being terminated before you lift your finger.
2. Long press actions acting like multiple-presses.
3. (The most common for me) Finger up events failing to register (resulting is erroneous long-presses)
But none of these are "lag". I believe there are grounding problems in the Vega and thus how you hold the tablet and the humidity and static of the environment can change the reliability of the touch screen. It's been reported that having the Vega plugged into a desktop via USB increases the reliability of the display (at least when also charging) which lends credence to the idea that it's grounding related.
What I have noticed ín particular is that holding the tablet in landscape mode makes the keyboard ultra inaccurate. You must press much below the level you want. E.g., if you want to write a Q you hit the A key. It's a bit bothersome while writing...
I haven't experienced any lag, just a slight deadzone at the bottom of the screen and inaccurate keyboard typing. Nothing major. I also haven't really noticed the messed up screen sensitivity when charging that people have been going on about.

The performance pack really reduces start up lag issues btw.
I've seen the device lag sometimes but since i installed pauls peformance pack the lag has gone away making the device so much better.
Well for me the keyboard is still a major issue. Not lag really, but it appears to register my touches multiple times. Right now Im typing this reply on my tablet and I have to go back so many times to correct multiple characters, spaces etc. Its just taking so long and requires so much effort to write a simple message.. for browsing and apps I love it but for email its horrible..

Is the power supply plugged in? (Screws up the calibration in my experience)
Are you touching the screen while it calibrates?
hi...just upgraded my nexus 7 to 4.1.2...its great to have landscape rotation on home screen but found a small bug.. .when fonts are set to HUGH and switching on from stand by to get the clock and slide to open screen...when in landscape, the clock sometimes does not show all the digits. ..ex. 11.45 shows only 11.4.....anyone got this problem or knows how to fix it?
One other thing that I found on the same screen when in landscape is that when sliding your finger up in the circle to go to google, if you keep sliding your finger above the google icon you will unlock the screen to the home screen instead of going to Google Now!!
thanks. .Michael Mock
Bums.
I haven't got an answer for you, but this seems to be the right threat to put what I've noticed in too.
Has anyone found that since 4.1.2 that their N7 doesn't like to connect to GPS/get location anymore? Before, it never had a problem at all, it was really fact, but now it just sits there 'getting location'. Irritating, but has anyone else got that?
I've also noticed that I can't plug my N7 in to charge without it suddenly turning on. Really weird.

I reckon the switching on when you connect the charger is a deliberate bug fix to avoid damaging the battery - the battery gets alarmingly hot (battery damaging) if connected to the charger and the nexus 7 is powered down (at least on mine that is). When android is booted up and running, battery charges with minimal heat production.

I can't say I've noticed mine gets hot when its off unless I leave something covering it, which I don't on purpose. But it seems to get a wee bit warm either way, but thanks. That would make sense.

Has anyone else noticed how after you wake up your PC after sleep a couple times that streaming ceases to work? My Shield can't find the PC at all no matter what, I tried refreshing it through geforce experience and such but nothing works except for restarting the PC completely. I'd love to just be able to hit my PC's power button and bam, right back into being able to stream.

Yes, my PC had this issue as well. I turned off allowing my desktop to suspend because of this issue.
Yeah, I unfortunately did the same. It'd really be nice to wake up the PC with Shield, hope its thought of for future updates...possibly in custom ROM?

I have a SM N900 Exynos running android 4.4.2 factory non rooted device.
I have bought it from an authorised samsung dealer not even 3 months ago.
I have noticed the phone freezing under load, like i had 4 downloads open on UC browser each of 200mb and was listening to songs via earphones on the native music player also had musixmatch open. At this stage my phone became very hard to control kept on lagging to a great extent till the point i pulled down the notification bar and system ui stopped responding and screen went off and only the capacitive keys were lighting upon touch, no haptic feedback. I had to restart my phone.
I have noticed this a lot whenever i have a lot of things going on, well this is an octacore device with 3gb ram. This shouldnt happen ever. It should be responsive all the time.
Also if i open a few number of apps and press the home button to go back to the main screen, the phone starts lagging. Shouldnt the memory management be good like the phone closes the unused applications by itself whenever ram is low instead of me going to recent apps and clearing some of them to regain performance.
Anyways i have some 128 apps in appdrawer including the system apps if thats any help.
Thanks in advance any help would be greatly appreciated.

The device comes with 3GB of RAM not all available to the user. First of all you have an Exynos device so you have 2.7gb RAM. I believe that they opted for a bigger RAM choice for the system to handle itself excluding user input.
So essentially you have half of the RAM to use for your other applications (1.35gb).
Anyways, have you tried clearing tasks in Task Manager? Stopped junk apps from wasting start up memory? If you have, then you really should reflash stock or Factory wipe, in order to see which apps you reinstall to prevent unnecessary slowdowns.
Are you using power saving mode while multitasking?? if yes then turn it off and try again, another tip is that phone are like mini laptops without fans they need to rest from time to time, so try to restart the phone or shut it off for few min, then test again, good luck.

Yeah you should check for this too ^^ (sorry not trying to tell the quoter but I have more to say)
I have over 650 applications installed (including system) and have no problem with lag, I even have Hyper fluency enabled on my launcher which makes it use double the amount of recommended RAM to make it look and feel better. No lag.

My phone runs good without lag, but after opening a good number of apps it slows down. Then i have to manually open multitasking(holding the home button) and swipe away a few apps. Shouldnt the phone automatically exit some apps when running low on ram?
Well as far as i know no one exits apps after using them, after they are done using a app nearly everyone uses the home button instead of exiting the app.
And no, no powersaving mode is enabled.

Just last month, a friend of mine had a problem similar to this: the phone responds to button press but there is specific period of time that the screen won’t respond. We ended up replacing the digitizer. It is a piece of glass on top of the display panel that conducts touch commands. Digitizers come with their respective circuits that when messed up, some, if not all, screen functions won’t work. But it seems that your problem is not the digitizer, so try booting to Safe Mode and observe the phone’s performance while in there.
If the screen still freezes randomly, some of the core functions may be causing the problem and there’s no other option but to perform factory reset but first, back up all your data.

Since i bought the phone in around 4 months the phone has frozen under extreme load only twice. Would you still recommend a a factory reset?
I observed that if a lot of apps are running in the background and phone starts lagging, I just swipe away a few apps from the multitasking area and everything works fine thereafter.

Not a user of the 2.2 full android.
Would have thought spin down would be controlled by the storage controller on the chip. I doubt Android has any built in mechanism to control this.

Ok! But why constant spinning on native firmware even sleep mode even can hear of spinning sound and small bit kind of vibrating?! Don't think this is main job controlled by controller (chip on hdd) there should be some OS or most likely and probably kernel command (deep sleep) when nothing goes through cpu. Take example: if you watching move from hdd - ok goes fine - when you press pause - last point has been stored in ram - and cpu stay idle and same time giving after certain time hdd goes in idle rest mode (something similar when you watching move from external hdd on pc - pressing play and move goes bit with kind of delay letting hdd fireing up first - sometimes you can even hear start point of spinning)
Maybe I'm wrong but this is my theory how should be
