Internal Storage

Hey i was wonder can you like take apart the fascinate and change the internal storage? is it a second sd card inside of it? and if so how would you go about making the files work on another ? clockwork?

It would probably be embedded on to the board itself.

I would say firmly that, no, you cannot replace/increase the internal memory on the Fascinate.

well i mean has anybody taken apart the phone yet? lol i was hoping that website that takes apart everything would of so i didnt have to be the first lol

Whether it has, or hasn't been taken apart by anyone, it's not a common practice to have removable/replaceable memory with these types of devices.
I consider myself a poweruser and have no real need for more internal memory.
You should be ok. You can always App2SD if you're running out of storage space.

well i have the lagfixme.bat until they make something better..by the way does the lag fix make media scan slower or something it takes forever to scan sometimes but anyways. i thought we couldnt app 2 sd until froyo?

No, the media scan is just slow and takes forever in and of itself.
We can't really "app 2 sd" until Froyo.
I'd consider myself a power user as well and I'm only using 214MB of 1.55GB internally. Everything else (music, movies, etc.) I keep on my SD Card, so it isn't too bad.

yea im kind of a messy power user i got files everwhere...but yeah your right...thanks for the input

Once I got all my core appspot that I know ill use on a regular basis I only used about 300 MB of internal memory. Beyond that I use another 100 or so for junk (hypnotoad and the like) I can't imagine anyone needing more than 2 gig during the lifetime of this phone.

[Q] Internal HD speed

Does anyone know the speed on it, since a lot of my high read apps have huge issues with my transformer. I wanted to also know if there was anyway to point or force them to run off my class 10 card I got in it.

Its not a hard drive, its NAND flash memory and it should be as quick or quicker than your SD card

Weird, for some reason my tablet seems to be getting slower and it's driving me nuts. Now I am not sure if it's the custom rom or not, maybe I should just say nuts to it and get rid of root and reload the stock rom.
Is there a way to test the read wright speed so I can double check?

Do you have a task killer running? If you do, then that's most likely the culprit.

Nope, the biggest issues are when just pictures or chandroid is running. They move fine but slow to a crippled crawl in a bit, as for a task killer I don't have any unless it comes stock off the custom rom.
Honestly it is annoying as hell when it gets to a craw and then force close over and over.

No, they both work fine on my nook and my hd2 and my other tablet. It's just the newest one I got (ie the transformer) that I started to notice the issue. I worked with the dev from chandroid and we tried everything and he said as he looked over the crash report that there was nothing wrong with the app.
On the stock build of OS, he said it was an issue being caused by splashtop stuff. Is there anyway to rip every program out by the core needed to run and let me add them one at a time to test?

If you're rooted, you should just be able to uninstall stuff with Titanium Backup.. but make sure you backup the app first.

Aye, I got root. I was hoping to find out if there was a rom that was just barebones. So more or less do a full backup and then pull them all out and test it one at a time? I can just do a backup in clockwork mod.

What is the best way to remove anything/everything? Cause if I got it backed up and if I blow the OS I can just do a recovery.

The easiest way would be to freeze the app with titanium backup, you could also just manually rename it or delete it.

Should be obvious. Does it look and act identical to the transformer?
Once thing I have found is that apps can run well on older versions of android but have issues with honeycomb. Like cut the rope, it crashes and is slower to load on the tablet but blazes on my evo. Asked the dev and he said its not yet developed for honeycomb.
My TFs internal memory is plenty fast.

Just root it without someones Rom. Stock would be your goal to see if a Rom affects it.
Watchdog from the market would help. It would show you what apps are running and how much they are using the Cpu
When I use Dolphin HD or Pad I can see when it's hanging up...not loading the page then..it dies lol freaking apps.

I will try that, honestly I just want a way to see what's going on with it. I am not sure if it's using all the memory or what with all the images it loads. Since my problems always come from mass images loading.

Possibly just eating up your RAM then - the SSD shouldn't be (that) active if it's image loading and not saving.

Well like with just pictures, it's a big display of thumbnails for viewing your images. I know it can cashe the data to make it faster but that just seems to make it slower, as for chandroid the longer I use it the slower it gets. So maybe it's not purging old data?

2 Questions - 1 about GB and 1 about slow Epic

Hey all:
I have been traveling on business all week, and was just wondering if there was new news about GB being in the playbook this week? I have a feeling if it were, it would be top of the forum, but just in case it is in a "unobvious" thread, I thought I would ask.
Here is my next question. My Samsung Epic is completely stock, except for being rooted. I have noticed it is really slow when switching to the home screen, and switching to and from apps. It is ESPECIALLY slow when bringing up the TwLauncher sometimes. I have tried clearing data on the TwLauncher to see if there was corruption, but same thing. I have about 110 apps installed on my phone, and all of the apps that can be moved to the SD card are already there.
Any suggestions would be appreciated.

No, and what is the question on the second one?

No news on GB.
Other question....your homescreens are taking longer because it takes longer to access and find all the apps on your sd card. SD card access is slower so the more apps on it the more it will slow down. Clean some apps off your homescreen that are on the sd card that you don't use and see if that speeds it up a little.

ouch. I had a feeling this was the case. Let me ask this.
I have the stock SD card in my phone (class 4 I think). If I bought a class 10, is the phone capable of utilizing those faster speeds, and would I notice the difference?

1. No news
2. You are running out of memory.

No, I had a class 10 card (recently got corrupted and I changed back to the included Samsung sd card) and I still had this issue.
I've heard that the biggest reason we see this issue with the home screen is because the Epic uses the RTS (murderous) file system. As you are rooted, I believe you can search for the solution someone had that puts a 1GB swap space on the SD card that uses EXT4.

This is interesting.
I wonder if a Class 10 card would help if the swap file is on the SD. I almost wish I would have installed the stock ROM without the bloatware, as I think that would also help my situation, since my internal memory is down to around 60 megs...
hmmmmm.

I have 140 apps and 98% of those are on my SD card - the other 2% that "can" go on the SD card, I don't move because those apps are in folders on my home screens and if moved to the SD card, on next boot the icons change to a default Android icon instead of the normal app icon.
With that being said, I am stock and rooted like you except that I have a kernel so I can overclock my cpu. My phone is fast and stable in every way and so is my wife's epic which I have set up almost the same way - I have no problems with speed in switching or opening apps.
I would try overclocking but stay stock IMHO.

Neither of them seem to backup the actual data that the applications use. What do I mean by that? I am talking about the saved login information for an app, as well as preferences, etc. It is never as easy as it should be.

I would only do the kernel and not a rom yet, baby steps! Read the OP at least 3 times so you can understand.
Make sure you make a nandroid before you try this, just in case somethings goes wrong. When overclocking, don't mess with undervolting until everything is stable, then baby steps.

I run exactly whats in my signature. I have duplicated the same setup on my wife's phone with the exception that I keep hers clocked no higher than 1.3ghz. Where I float back and forth between 1.3ghz and 1.4ghz, because I am testing battery life. I get as good or better on battery life and a snappier phone on 1.3ghz and a little less battery at 1.4ghz, but that is only when I play a game at 1.4ghz. Under normal daily usage, I would still have to give the edge in battery life to 1.3ghz, but 1.4ghz sure is fast!

I have the free version of Titanium Backup and my App Data restores perfectly.
I'm thinking same as one of the other posters, more than one instance of your apps are killing your ram, what I do is chop down on apps, and look at what apps are running under processes. Remember that out of those 110 apps you have installed, not every single one has optimized programming code, so in theory, half of those are making new bugs that your phone has to bitterly endure. For titanium backup I do batch restore apps+data. Maybe you're just not restoring right. There's so many options that I find it possible. Imo opinion, I don't reccommend OC if you want battery life and for your epic's overall life to end sooner. As for gingerbread news nothing new yet, but it'll come out when we least expect it, I'm sure.

I have MyBackup Pro and I don't even use that anymore, as I nandroid every 3 to 5 days or when I am going to do something drastic that could cause problems from the unknown. As an example my last unknown that was kind of glitchy was when I upgraded to Superuser went to 3.0
If you are rooted, just do a nandroid, if you have a crash, it will bring everything back just like it was when you made the nandroid.

And "that" is why I said to just flash a kernel first. I am almost sure he would go nuts, because he has to flash SRF 1.1 first then SFR 1.2, then a kernel and make sure he has been converted to ext4 from rfs, than probably have journaling on, and the list goes on.
Go kernel first! And if that works and is stable and your phone works perfect after a week of use, then you can go on to the next step!

That is awesome advice. That is what I did back in November. Genocide was the first thing I flashed after rooting to change my bootanimation.

Its due to apps on sd card having a shortcut on a home screen or on a folder on a home screen. I don't think file system, kernel, or ROM will improve that very much. I would hate for you to go to all the work to find no improvement.
The cache and speed tweaks could help and a faster card could help. You might also give a new launcher a try. In the end, I decided to just keep apps on internal memory that I needed on home screen. Same as the 98% - 2% guy above.

Improving lag

Evening all. Just wanted to report that I've had good results using the Forever Gone app from the play store to improve lag on my non rooted xt925. It had gotten a bit sluggish lately.
The app essentially "formats" the free space on your ROM memory which seems to restore performance pretty significantly. Made a big difference on my nexus 7 too. It doesn't touch any of your files.
No affiliation, it just got recommended to me and I'm happy with the results. Especially since it doesn't require root.

Yeah, it does take a bit of time to do it's thing. Especially if you have a reasonable amount of free space. But it's definitely worth the wait IMHO.
I started it before I went to sleep one night and just let it do it's thing. I'm not sure how long it took on my Razr, but it was probably about 20 minutes on my Nexus 7. Again, definitely worth the wait though.

It takes for my razr hd with 9GB free space about ~40 min

Giving this a try. Hoping for similar results

Someone tell me how it goes!

What I read from description in playstore: This app cleans already free space on your SDCard similar to writing Nullbytes into the sectors of the SD. No defragmentation.
Every scriptkidd should be able to write an app like this. The purpose of this app is to *hide*/destroy files that were being deleted from your SDCard so that they cannot be recovered by Undelete-/Recovery-Software.
I wonder how someone comes to the conclusion that this app would format and defragment rom memory or increases performance or decreases lags?
Also: Is this app 100% trustable? Nobody can ever know what happens to the data that is being scanned; maybe exaggerating a bit, but who knows if your sdcard-data gets sent to north korea?

It works on the theory that when a file is deleted or moved off your memory it retains data that allows it to be recovered at a later date by a data recovery app. This retained data may slow down the I/O of your memory, creating lag. Remember that solid state memory works differently to optical storage. On an optical HDD or a DVD this type of thing wouldn't have much (any?) benefit. SSDs work differently though.
So what if every "scriptkidd" could write an app like this? How is that helpful to this discussion? I don't understand that comment...
If you don't trust it or don't believe the theory behind it, don't use it. Personally I don't keep stuff on my phone that I would be terribly worried about the North Koreans getting hold of, but I can't speak for others...
Look, at the end of the day, it's not my app. I couldn't care less if you install it or not. I used it and it improved my lag. It's that simple. I thought others might like to hear about that.

Hmm. I guess there is something getting pretty mixed up. Everything that this App is doing is cleaning up some bytes/pointers on either the internal or the external sd card memory (by stuffing the sdard's free space with Nullbyte datafiles).
(Strongly simplifying in nearly 99% of "roms" the Android OS system files reside on the system partitions of *internal memory* and most apps reside on the internal "apps"/"data"-partition. Those partitions are not reachable for "Forever Gone" since it doesn't use root privileges, so these partitions (and it's "empty" memory space) cannot be "optimized" by this app. Therefore it *can not* reduce lag for system-apps like e.g. launchers or standard apps. "Performance Improvements" for whole systems are to be regarded as simple placebo effect - no matter how many fivestars this app achieves on playstore.
There's a *slim chance* that it maybe "kind of" works for Apps that make use of Apps2sd, when those Apps (and their data-files/databases e.g) get stocked/moved unto internal or external sdcard space. Or Apps that make frequent permanent use of internal/external SDCard space like games or navigation programs with offline map files on internal/external SDCard. So that those apps "start faster" or "feel more responsive".
Until there's no empiristically satisfying performance measurements ... it is of course allowed for everyone to "believe" in the magic this app is doing ... but only that.

I tried it too and didn't really see a noticeable difference. Theory being that flash memory has to do a wipe before write which slows it down. By wiping the card ahead of time, checksum would already be zero. As someone pointed out it only does the SD card and not the data partition where most writing happens. It would only help someone with specific SD card issues I think. It could actually make things worse if the app isn't wiping correctly. I would imagine that Android does garbage collection and TRIM but I've never looked to see if any partitions have the discard flag enabled.

Look, you're entitled to be skeptical. No dramas. I would agree with your comment that the app obviously can't access the restricted areas of the internal memory. That's pretty clear. But it doesn't claim to do that. The way I see it, any app that accesses free space in the internal memory could potentially see an increase in performance. Anything related to the photo gallery, music, movies, books etc which are all stored in accessible area. Also, I don't know about you, but when I look at the accessible area of my internal memory, most of my apps have created their own folder in there. I don't move any apps to SD, I don't see any point. So I can only assume each app is accessing the accessible internal memory of it's own accord. So whether it makes sense to you or not, many apps are clearly accessing the area of memory in question.
Secondly, of course the Android system and launcher would access the accessible area of the internal memory. They need access to images (wall papers etc), sound files etc etc.
I'm not sure what sort of empirical evidence you're looking for? Should one of the Universities begin a research project on this app? Are there many apps that come scientifically proven?
Again, whether it makes sense to you or not is irrelevant to the whole argument. I can 100% guarantee that this app made a significant improvement to lag issues on my Nexus 7 (not rooted). The difference was very obvious. If you believe it's placebo, great. But I'm happy that my Nexus 7 is performing how it used to in my placebo world. It had become frustratingly laggy lately. The app also made a difference on my Razr HD. Not as much of an improvement as the nexus, but then again, the nexus was much laggier than the razr before hand. If this app is magical, where can I find more magical apps?
I'm not a scientist and I'm not going to perform a peer reviewed experiment on this app. So if you're not keen on apps that aren't scientifically proven, it's probably best to give this one a miss...

I would imagine that Android does garbage collection and TRIM but I've never looked to see if any partitions have the discard flag enabled.

It definitely accesses the accessible partition of the internal memory.

You'd be better off with this to fix lag but you must be rooted.https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix

There are plenty of solutions for rooted devices. I hadn't come across anything for non rooted devices that actually made a difference until I used this.

Gave it a try, no noticeable difference unfortunately.

For anyone interested, it seems like Android 4.3 has a feature built in which is very similar to the function this app performs. The article refers specifically to the Nexus 7, but it's obviously relevant to pretty much an Android device.

I tested this app, and it's really great. But as lobie81 said, android 4.3 do the same thing with the implementation of TRIM

Duplicate storage?

So I am cleaning up my phone when I notice I have these two folders that are identical.
Main question is, which one is safe to delete without making my phone go crazy?

Definitely not. Leave it alone; everyone has those folders and I assure you they do not exist twice.

What makes me scratch my head is that both folders are the exact same size with the same content so I just don't understand why my phone needs double since it shows my storage at 17GB and want to free up some more space

One is a link to the other. They are not duplicated, they are one and the same files

Alright, think about it this way. Open your file explorer and check the size of either of the folders by looking at their properties. For instance, mine both show that they add up to 10GB. I've also got about 3-4GB of space being used for backups and my system partition, and even more for apps. So my guess? Probably using at least 20GB of my storage. Keep in mind that I have a 32GB phone. Now if I go to settings > storage, it shows that I have 12GB of free space, so it all adds up. If you do the math, I couldn't possibly be using 20GB total for both of those folders, so they have to just be different paths to the same location, and yours probably is, too.
My conclusion: if you delete one of those folders, nothing good can come of it. Look elsewhere and account for your system itself (I see you are using the stock firmware, which is quite large due to LG bloatware) and the apps you use. Check Settings > Storage and see what's using so much space.

Thanks for confirming everyone. I guess I need to browse my phone system with my PC to find where the real bloat is at. Yes the LG apps do take up a bit of space.

You might consider finding an AOSP ROM that fits your needs if you're looking for a bit more space. They tend to be a lot smaller than stock roms. Also, try clearing your cache.

Knock on and the remote app have been ported and work very well. Check out Mahdi ROM, it works great on my G2. You can find the ported remote app in the Themes and Apps forum. Good luck!
