[Nook HD, HD+ General] razholio:
Oh, I agree. I hear what you and swaaye are saying here. I may have had some expectations creep with the HD+ because I found it more useful than I thought, but I don't have unrealistic expectations. In the first couple weeks it was great. Very little lag and fairly smooth overall. However, with enough written to the eMMC, it's progressively slowed down matching the expected behavior of an fstrim-less flash device (see nexus4, 7 and 10 after a few weeks/months of ownership) I installed alot of apps, and moved alot of files around so I'm not surprised, but waiting 3-5 seconds for an email to open in gmail, and then up to 10seconds for a web page to open, as well as multiple seconds of zero touch response is ridiculous and not commensurate with the power of the hardware.

If my suspicions are correct, then everyone will start to see their lag increase progressively as they use their internal flash and fragment it to the point of impacting I/O performance.
[Nook HD, HD+ General] swaaye:
I think some of what you describe comes down to Android-related quirks. Maybe if we had >= 2GB of RAM so multitasking was more viable and more of the filesystem could be cached it would work better. Perhaps Android 4.3 will be an improvement.
[Nook HD, HD+ General] jpisini:
In theory one could use titanium backup and reinstall the os every few months. I really think it is what you are used to. The nook is twice the speed of what I replaced so for me it is wonderful for others it may be slow.
[Nook HD, HD+ General] leapinlar:
Actually a nandroid backup followed by an advanced restore of just /data might work better.

[Nook HD, HD+ General] razholio:
I would agree, except that this lag wasn't present when the tablet was new. Combine this with the nexus7 experience (blazing fast to laggy as hell over a few weeks-months) and the experience of those who have successfully run lagfix and it would appear that the fstrim issue is a significant contributor at the very least.

I'm not sure if this is what I did as I'm new to the whole CWM, CM experience. I did a full backup in CWM recovery, then I formatted /data and /cache and then did a full restore. I was hoping that this would somehow serve the same purpose as a fstrim, but things have not significantly improved.

---------- Post added at 09:00 AM ---------- Previous post was at 08:53 AM ----------

I believe you posted in another thread of your experience helping a user recover from a lagfix-induced soft-brick? If that is the case, would you mind describing what you had to do? I'm imagining that booting into CWM from microSD and restoring a backup would do the trick, but I don't know how much automation is included in the restore process. was there manual partioning/formatting involved?

thanks.
[Nook HD, HD+ General] SCWells72:
I can definitely attest to the fact that TRIM makes the single largest difference in minimizing lag on this device. I certainly understand folks not wanting to use LagFix given that it's tanked a few devices (mine is fine so far, knock on wood!), but hopefully 4.3 will make a big difference, assuming that the TRIM feature can be safely enabled.
[Nook HD, HD+ General] razholio:
well I appreciate you speaking up on your experiences with it. I took the plunge and ran lagfix on just /data and /cache (the defaults) and can report success both in lag-reduction and non-brickage. For the nay-sayers, this will not make your nook faster or smoother. However, it will reduce the very serious lag in opening emails, web-pages, and just about anything that requires caching. I'm now able to jump from email to chrome w/o the multi-second (sometimes 5-10 seconds of a frozen tablet!) lag that plagued me before running lagfix. This is not some snake-oil mystery meat. this is a well documented issue with the way some flash storage will fragment due to the difference in block sizes and inherent garbage collection the flash storage controller has to perform.

Count me as a fan of lagfix.
[Nook HD, HD+ General] SCWells72:
Glad you've had the same positive experience. I'm not sure I totally agree with your point about "this will not make your nook faster or smoother", but not because I think it speeds up the CPU or GPU, but because app switching isn't the only thing that suffers from lag, so does some in-app performance. For example, Flipboard had become completely unresponsive for me even after it launched, presumably because it was seeking around superfluous blocks on the flash storage to find its content. After running lagfix, Flipboard is almost as smooth as on my iPad 3. Again, this is because of the same issue that's helped by TRIM, not because of anything more complex, but the net effect is definitely a better experience overall.
[Nook HD, HD+ General] razholio:
totally agree. Reducing (and in some cases eliminating) lag will make it faster and smoother, sure. What I meant was that it wouldn't make the nook faster than before the eMMC got fragmented, so it won't be any faster than it was when it was new. I was making that distinction for the sake of the people who think those of us complaining of lag are just keeping unrealistic expectations of limited hardware.

While the CPU is pretty impressive, apparently the GPU is seen as a potential bottleneck at this resolution. Slow-downs from intense garbage collection in the JVM due to high memory pressure seemed like a reasonable candidate, but RAM speeds what they are, it just didn't fit the bill for the kind of latency I was seeing. A stutter here or there, and apps restarting after being killed in the background is what I would expect, but not the tablet freezing up for seconds at a time.

I was always happy with the speed of the nook. Animations were fairly smooth and scrolling was smooth enough. My objections were to the increasing frequency of lag that would render the tablet totally frozen for seconds at a time. Ain't no GPU bottleneck gonna do that.
[Nook HD, HD+ General] swaaye:
I ran a memory bandwidth benchmark written by someone that I know understands these things. The app is called RgBandwidth.

The results probably tell exactly why the HD+ is sluggish with graphics in some situations with its 1920x1280 resolution. Its memory performance is lacking. This is definitely a bottleneck for 3D graphics but probably also an issue for full screen GUI fills and other things.

[Nook HD, HD+ General] Azurael:
Hmm...
[Nook HD, HD+ General] rushless:
The test seems to support my "theory" that there is a specific design issue with the Nook HD+ that creates bottlenecks, over and above the 1080p display hit. From a speed standpoint, it will probably never be as fast overall as my Excite 7.7 or TF300, but does the job for comics, browsing and most games and all emulators. The lag is the "catch" to having the great price point and display. There ALWAYS will be a catch to something with everything ;)

I am happy with 10.1 and will not upgrade mainly due to Flash. I like using Flash and it does NOT perform as good or work with as many sites with 10.2. Google are doing their googlest to kill Flash working in Android. Meh to them. With 10.1, most Flash supporting browsers work fine, but hit and miss and problematic with 10.2, in comparison.
[Nook HD, HD+ General] swaaye:
Note though that this is only testing the CPU's ability to utilize memory bandwidth. Dual channel (64bit) LPDDR2 466 should have a potential of around 7.5GB/s. But at 1920x1280 that's still not much for graphics.
[Nook HD, HD+ General] williamlaw:
can improve by other ways ??
[Nook HD, HD+ General] j0a0a7:
I'm happy with the performance running cm 10.2 lucky that I've not gotten any boot loops or reboots. Games run well and mx player has handle every video files I've thrown like a champ. For the $140 I've wasted to the 32gb nook hd+ so far been the most bang for my buck purchase.
[Nook HD, HD+ General] swaaye:
1920x1280 is very high resolution output. It's unlikely that the PowerVR SGX544 has enough fill-rate to deal with that and maintain high frame rate in 3D games of any significant complexity. What would be very useful would be the ability to use a lower resolution in 3D games. But I'm not sure if Android can do that.

Running 16-bit color depth would probably help because it would reduce the amount of memory bandwidth used. That can be done. On my old Nook Color there is a custom kernel that runs 16-bit color depth. There is a downside to that though - gradients will have more color banding. It's not usually that much of an annoyance though.
[Nook HD, HD+ General] Rcoolb2002:
Here is a way to adjust the screen resolution, used on a NEX7 but should work for the nook as well.
[Nook HD, HD+ General] RageAgain:
This says it doesn't work correctly on 4.1 and not at all on 4.3, funny thing that a lot of emmc CM rom users are going back to 4.2 or stock anyway. I have games that I like that won't even sideload on the HD+ because of what I believe are resolution related issues, so this may actually help. I am on 4.3 though, and though I am considering going back to 4.2 ( 10.1 8/12 ) I haven't made up my mind yet...
[Nook HD, HD+ General] rushless:
The devs can do it (usually). The app can scale to the correct resolution as needed, but is simply blowing the image up to fit, rather than each native pixel being pushed by the gpu. This is why some games play in small boxes, since the game was set to app native res, but no scaling. Hardware and OS fragmentation are the main culprits. Most games are not created at 1080p, so no need to push each pixel. It would be nice if there was a simple scaling default. That is how most emulators work. The GPU is not pushing to each pixel. If that were the case, PSP, PSX and N64 would be be slide shows on the Nook HD+. Instead, they are actually as smooth as my Excite 7 and TF300 (if not smoother due to 4470 cpu). The scaling is why some games are fine with the 4470 and others are not. All depends on how the dev set the app up to work with the gpu and if the gpu reads the instruction as intended, or nulls to full 1080p pixel pushing action. A game that tries pushing to all pixels is Asphalt 7 and is why it is slow. On the opposite end, NFSMW is as complex, but plays smooth on the Nook HD+. The reason is the game scales up to fit 1080p rather than pushing to each pixel.

As far as 16bit, I notice some games are sloooow with that setting. Most seem fine, but some do not like it.

[Nexus 7 Q&A, Help & Troubleshooting] demmalition1:
I am having an issue when updating my Nexus 7 to 4.3 from 4.2.2 using adb. I have successfully updated from 4.2.1 (and 4.1 to 4.2.1 on my Galaxy Nexus), so I have some experience in this. When updating to 4.3 everything runs smoothly with the file transferring and verifying the package.

However, I get the following message when it says "Installing update..." appears:

You know....I am soooooo fed up with this!!! and I need help.

I have auto-updating turned OFF and software scheduling updates OFF, and then now, I just connected to my Wifi connection and my phone started to download a 350MB software update bundle even though every AUTO Checking of Software Updates are TURNED OFF. I dont know why its still downloading updates when I have all of these disabled to automatically check for updates.

Please see print screens.

I DO NOT want ANY software updates to be downloaded especially I dont even know what updates they are.

Please help me on this. I want this to be disabled.

Just sick of this!!!!! I mean really....

Now, I do not really know what this 300MB update bundle was, but it wasnt the Android 4.3 update as I just checked.

I have no clue whatsoever on what updates were installed.

How can I check what updates were installed?

Thanks
[Galaxy S 4 Q&A, Help & Troubleshooting] gee2012:
If you have root you can disable Samsung updates by deleting FWUpgrade.apk and FotaClient.apk (and the odex files) with root explorer.
[Galaxy S 4 Q&A, Help & Troubleshooting] itsonlyme999:
My phone is not ROOTED.

Can you post screenshots of this please on where I can find this in order to disable this?

I want to disable auto-updates because Im afraid it might "break" things.

Thanks, I would appreciate some print screens.

Will Android version 4.3 be downloaded automatically as well?

Now that, I will not mind if 4.3 would be installed automatically since I heard that should fix the "lag" issue on the screen on most S4 phones.
[Galaxy S 4 Q&A, Help & Troubleshooting] gee2012:
You can`t disable it if you`re not rooted. What country do you live in and whats your installed build version?
[Galaxy S 4 Q&A, Help & Troubleshooting] itsonlyme999:
Hungary.

Ok, if I root my phone which I do not want to do then is there anyway to disable these updates?

I just want to conserve the phone storage space which is now approx. 8.36gb and therefore I do not want these updates.
[Galaxy S 4 Q&A, Help & Troubleshooting] Gillion:
Since your phone is factory stock an update wont break things.

Samsung updates are not to be feared.

And the updates. Dont waste space... as the software gets refines you get more.

I now have 9.1 gigs when I use to have 8giga when I just got the phone

Samsung is optimizing the software and it is getting slimmer.

Updates do not waste space.

So relax... it sounds like this is your first Samsung flagship.
[Galaxy S 4 Q&A, Help & Troubleshooting] itsonlyme999:
Will Android 4.3 be pushed out like this as well?
[Galaxy S 4 Q&A, Help & Troubleshooting] Gillion:
Yes
[Galaxy S 4 Q&A, Help & Troubleshooting] itsonlyme999:
Ok, so I do not have to ROOT or manually do these flashing of ROMs or something like that in order to install Android 4.3?

Hope not....

I just want it to be pushed out automatically and install it.
[Galaxy S 4 Q&A, Help & Troubleshooting] Gillion:
You will get 4.3 automatically if you leave the software update feature on.

Samsung update services are decent.

For example the Samsung Galaxy S2 was updated to 4.1.2 via OTA even tho it is considered an old phone from the Gingerbread 2.3.4 - 2.3.6 era. (FEB 2011)
[Galaxy S 4 Q&A, Help & Troubleshooting] itsonlyme999:
So do I have to just tap the "Check for Updates" and thats all?

Because I would like to leave the "Auto Update" DISABLED.
[Galaxy S 4 Q&A, Help & Troubleshooting] Gillion:
Yes.

But my advice... leave auto update on.

If you tap the check for updates button you may see an update but it wont download because the update server space is full.

Your fear is understood but unnecessary.

Its best to let it download by itself over wifi.

When it is done it will ask you if you want to update... it will not reboot your phone without you knowing.... nor will it install new software without you knowing.
[Galaxy S 4 Q&A, Help & Troubleshooting] itsonlyme999:
Sorry, but one more last question. I tend to turn off my WiFi on my S4 most of the time even when I am at home.

Now I enabled the Auto Updates as you recommended. But as most of the time, I have the WiFi OFF and only enable it when I need to.

Will that be OK for the updates?

So far, I did not get the Android 4.3 update.
[Galaxy S 4 Q&A, Help & Troubleshooting] gee2012:
3G strains the battery much more than wifi bro, leave wifi on if you can for better battery life. OTA`s can be downloaded on 3G but wifi is cheaper and faster. 4.3 isn`t out yet, will take another 2-3 months for the official one, leaks may come earlier.
[Galaxy S 4 Q&A, Help & Troubleshooting] Gillion:
As the user above says.

Leave wifi on for better battery life when you are at home.

If you turn off wifi and do not want the phone connected to the internet make sure you turn off mobile data as well.

With your internet service off: The update will just take longer. I am not sure the updater service downloads the data in pieces as a torrent client or download manager would do.

So its best to leave it on... go to sleep and wake up to see the notification that the update has been downloaded and ready for installation.
[Galaxy S 4 Q&A, Help & Troubleshooting] itsonlyme999:
And is there a way to uninstall an update or to roll-back in case an update might "break" things?
[Galaxy S 4 Q&A, Help & Troubleshooting] expl0de:
If you have problems after update, you can make factory reset, which will erase all personal data from the phone and fix the errors, keeping you with the lastest firmware. Now you can go to application manager/all apps and find SoftwareUpdate. Disable it and I think, you wont be able to update before enabling it again. No root needed to do this.
[Galaxy S 4 Q&A, Help & Troubleshooting] Gillion:
No you can't roll back as you would on a PC from the phone itself.

What you will have to do is download the version of firmware you want and like and use a PC based software called ODIN to re-flash the phone.

If you do this you can keep your old settings (it wont wipe your personal data) and "roll back" to a version you preffer.

However updates seldom if ever break things in my region. I do not know about other regions.

For example: I keep my S4 STOCK STOCK STOCK so I have never had the need to roll back any update.. and nothing so far has broken in the 4 updates I have received over wifi.

Other people may have other experiences, possibly bad ones with apps crashing or the phone being slow.

So what they normally do in such a negative case is a Factory reset.

A factory reset will have the new firmware but it removes all your settings and downloaded apps and presents the phone as if it just came from the factory.

Your settings and apps will then be reloaded once you log into Google and / or your Samsung account.

So relatively speaking it is not a major hassle.

[HTC Sensation] Mr Davo:
Hi Everyone,

I downloaded a "HTC One Sound Pack" through "My Elegancia", an App that allows me to download mods for my Elegancia (Sense 4.1) ROM. I installed the zip file (with the sound pack contents) using 4EXT Recovery, and rebooted my phone. Unfortunately instead of seeing new sounds I see two of everything in my "sounds menu" (turns out I already had HTC One sounds installed by default with the ROM version that I am using).

Screen capture of the sounds double ups!

I have used ROM Toolbox to investigate the location of sound files which are used within the theme, and can see that only one copy of each sound file is stored in internal memory. This fact leads me to believe that a configuration files has been altered, and it is my hope that I can locate the file and change it back.

Ultimately my goal is to see only one of each sound options in my "sounds menu". If anybody can help me to achieve this it will be greatly appreciated.

Kind Regards,

Davo
