[Q] appreciate some info

s 3G/4G signal and ram
1. *#*#3282#*#* enter msl to change port #'s to 0 and 0.0.0.0 so 3G is faster. Are there different instructions for ns4g. Port #'s under multimedia and says they are not set. So I'm asking if the hack for getting better 3G works on this phone ?
2. Since storage is built in, can it be allocated as virtual ram. I have seen this question before, but it always refers to a removable storage card. Don't really want to free up ram, just have more for usage.
I have searched, but maybe the question isn'tbeing asked correctly. If there is a point I'm missing, i would appreciate any info.
Was told first question doesn't work cause we don't use proxy port for 3G/4G on ns4g, would like to know what is uses and if there's a hack to get better signal

This belongs in q and a or general. You can't write to sd for memory.

Didn't see Q&A for Android Development
Can you elaborate on why you can't use storage memory and allocate as virtual ram. Just like on a PC, i would think because its apart of the phone and not removable.

Because ram in a PC is volatile, meaning its meant to be written to and rewritten to continousoy as long as there is volatage applied. The cathc is when that voltage goes away so does the information.
With SD storage like we are often dealing with on our phones it is nonvolatile memory meaning it can keep its data after the voltage is removed. The downside to this is that it is designed to be written to and stored as opposed to constantly being written to like RAM is. As a result, this type of memory only has a certain number of writes that it can have performned on a certain area before it goes bad and cannot be written to anymore. In essence it "goes bad".

Thanks for the info
So i take it that when a PC uses the hardrive as virtual ram for a bigger cache, then its essentially doing the same. Explains alot more than what Eastwood was sayin.
Heard about removable SD cards going bad from wear, was hoping because this was permanent storage almost like a hardrive that it could simulate the the same way. Prolly means my harddrive is gonna go pretty soon on my PC then.

Was also asking because most of research i read was related to removable SD storage, and since my storage is built in and not removable through a slot like most phones, i was curious if the method would be the same. Guess not

So the prl hack only works for some people, witch is not me. And trying to allocate memory as virtual ram for a larger cache is not going anywhere. From what i have read this is theoretically possible, but has only been done on removable SD cards. Witch wears the card down and is too slow for usability. This phone is way better than my old Evo 4G, but didn't have battery issues or signal issues on Evo 4G. Guess its back to Sprint, cause I'm still within my 30 days. Somebody stop me and tell me not too, that this is the better phone .

Phone finally fast

Hey Guys,
I finally got my phone to work at a decent speed. Here are the things I did:
1. Used Apps2SD to move the apps from internal storage to SD Card. Wondering why this helped? As far as I understand the apps are run in RAM and internal storage is used for storing data and apks etc. RAM is freed up by Android as and when needed but freeing up internal storage doesn't give android more RAM.
2. Use Autorun Manager to prevent some apps from starting up and remaining in memory. Now this I understand because this gives more RAM to android and avoids unnecessary swapping when applications are started up.
3. Used 'SD Booster' to increase sd cache size to 8192Kb. This gave some initial benefits but later on it became very slow as usual.
Bottom line is I am still puzzled by Android memory and SD card management. I am pretty sure though process swapping in and out of memory is what caused my phone to slow down. My Samsung Droid Charge is supposed to have 512MB of RAM but most memory managers show only 374MB and 2 GB of internal storage and most tools show only 1.2GB. Why would this be? Am I missing something or should I use a different tool to analyze my memory.

Not sure about RAM but usually when u buy a hard drive the bigger the hard drive the lower the actual number of gigs. Maybe it is actually 1.2GB

1. This one must be a placebo effect because if anything moving apps to sd card will make the phone slower. Our internal memory has way higher i/o speeds (especially on ext4) than the measly class 2 sd.
2. This is usually not a good idea. The processes you "block" will actually still run but they will be insta-killed. They will keep trying to start up and will drain the battery.

Thats what I thought. Im no guru, but out of all the reading Ive done, they have all said that moving apps from the sdcard to internal speeds up things.
Im looking at ways to speed up my wife's droid charge. Shes been complaining about it and finally gave me the go on rooting and maybee ROMing. I would like to stick to stock if possible so she wont run into any problems but if I have to I will install a custom rom. Any links?

Nope this is no placebo effect. The phone has become very fast. There are several posts that say that moving the apps to sd card speeds up the phone. In fact of all the things this is what sped up my phone the most. Why else would app2sd be so popular? Read #4 on http://www.talkandroid.com/guides/b...lean-up-and-speed-up-your-android-smartphone/ .
To further speed up my phone I am trying to overclock. My phone is stable at 1.2GHz but at 1.3 GHz it reboots after some time. To make it stable at 1.3GHz should I increase the voltage at that frequency?

Read it again. That's only about getting extra app space on smaller-storage devices. They actually recommend against moving things you use frequently in your linked article.
I'm with the others. Any gains you're seeing from this are placebo. There's nothing inherently faster about external storage.

It has a total of 512MB RAM, and that is for everything, so the GPU and other such things have to take their share from the total pool. On the GB releases, that leaves us with 374MB. It's better than it used to be. On the Froyo releases, we only had 327MB to work with.

No, on a hard drive (or solid state drives or even SD/memory cards), what you buy is what you get. However, due to formatting, space reserved for backup/spare sectors, and what is considered a "gigabyte" to manufacturers vs consumers (1000 mb vs 1024 mb) you often end up with around 95% (probably off on that percentage) of the stated capacity. With RAM this is not the case, as that type of memory doesn't need formatting as its holding raw data with the computer making up its structure. And manufacturers of RAM are in agreement with consumers as to what a gig is.

This is the difference between a gigabyte and a gibibyte. Hard drives are usually advertised in gigabytes (literally 1 billion bytes), while most OSes use gibibytes (2^30 bytes, or 1,073,741,824 bytes), since they do everything in "base 2", or binary. So an advertised 10GB hard drive has 10 billion bytes. Once you format the drive, the OS reports size in gibibytes, so you end up with:
Code:
10,000,000,000 / 1,073,741,824 = ~9.31GiB
That's also why if you look on most hard drive packages, it says "formatted size may be different than advertised size" or something similar.
Just a random fact of the day. Feel free to ignore it.
On topic: I don't believe the giga/gibi (or in the case of phone RAM, mega/mebi) is the issue. 512MB converted to mebibytes is roughly 488MiB. I believe the Charge is a 512MB device with some of that memory reserved for OS/system-only purposes. I could be wrong on that, however, so if anyone could clarify that'd be great.
Edit: Could have sworn I read through all of the replies before replying myself. I guess I didn't because multiple people beat me on both points by a day. Sorry about that duplicate info.

The number one lesson I learned from buying this phone
Check the amount of run time memory before you buy a phone, especially if you have two companies like Verizon and Samsung loading bloatware. You were forced to root the phone and rid yourself of the bloatware, or not buy apps. I totally agree with the OP. He is 100% correct about the run time memory.
So I restored back to factory to get ready for another root. After the required Verizon and Samsung updates, hitting the clear memory button, I'm using 268MB of 373MB. Now I know the OS can swap, (because we love paging), but it really is ridiculous. I can't wait until March. Good luck everyone.

I couldn't understand what you are saying here. From what I understand you are saying that is that when you rooted your phone you had 512MB of memory but after you installed Verizon and Samsung updates it started saying you had 373MB. So is it that Samsung and Verizon updates are taking away about 147 MB of memory? What is going to happen in March?

No. Hardware wise the Charge has a total of 512 mb of RAM. The GPU and other hardware have to take from that pool, and the end result is that the Android OS has 373 MB of RAM to use. Verizon and Samsung bloatware and updates have no control over the hardware aspect, but the bloatware DOES utilize some ram while the phone is running (but does not take from that pool). March is probably when his upgrade is.

I am using Eclipse 1.4 with PBJ.

Ok so I can clearly see that my phone is becoming slow again. Not sure as to what it is related to. Though one thing that surprises me is that I overclocked the CPU to 1.2 GHz and set the governor as 'conservative' and sometimes even ' smartassv2' but it changes to 'ondemand' even though I never changed it to that value. Why is this happening?

Plugging the phone into a pc does that for some reason.
Sent from my handheld computer using electromagnetic radiation.

I have to agree that even though my phone was initially fast it slowed down considerably after some time. Frustrated I then backuped my phone using Titanium backup and installed Tweaked 2.2 Rom + PBJ. But this time I did the conversion to EXT4 and the phone has become super snappy and the fastest I have ever seen. However, I am not rejoicing right now because I have only installed some very necessary apps like navigation, yelp etc. Don't know if the phone will be come slow after I install more apps. On Seepu I can see for the first time my used memory is green and this probably is a major reason why the phone has speeded up. Another factor is the EXT4 conversion.

Infinity was known for slowing down over a short period of time. Tweaked 2.2 is quite a bit better. But running a Droid Charge for several days without rebooting it once in a while will cause it to slow down too. Just reboot when it starts slowing down. It should help.

Before I add any more apps I want to save this state of the phone so that I can go back to this if the performance degrades. What do I have to do for this? I used Titanium backup but I see that it saves app data and you have to install each individual app. What I want is to make one click and restore my phone back to the state it previously was. Should I do a nandroid backup

Is the I/O problem gone? Is JB any better?

Hey everyone.
Im thinking of buying this tablet tomorrow, but Ive been reading about this I/O problem and dont really understand what it is, but it seems it has something to do with the memory speed being bottleneck and causing lag and apps crashing.
Is this problem gone with lastest updates or is it still there and a big issue avoiding me to buy this tablet?
Also I heard you cannot root the device without losing warranty or that I need to contact Asus for it or something like that. Is it easily rootable?
Does the tablet lag big time or slow down over time?
Thanks for the help.

If you are willing to unlock then this tablet can go as fast as any other.
Stock w/root you can still get it going pretty well.
don't know about running without root as I did that day 1.

Mine is stock and not rooted, and it lags too much. Way more than my Galaxy Nexus GSM running 4.1 JB. Chrome browser would have very jerky scrolling and even the stock browser would be unresponsive. I will root and then report back any differences

I 'me very happy with mine - stock with no root. I have two other JB devices, Nexus 7 and Nook Color with CM10 and all show the same startup delay on some apps - so I blame the apps not the devices.

Mine runs fine. Not as fast as my note 2. But the Note has twice the ram, processor is clocked at the same speed as the transformer and the screen resolution isn't close to the transformer.
I'm very satisfied with the speed. I don't notice any lag. And the resolution is great.
Although I have to say I don't use it as much since I got the Galaxy Note 2. (I mainly use my devices for web browsing, and the note 2 is a great size for that)
I still have some really good uses for my tablet, though. In the my cloud app it has the splashtop remote built in which is a nice bonus.

As Thats OK ^^ already said, rooting will not cause you to lose warranty. You're probably confused with unlocking -- which is the opening up of your device to flashing (of custom ROMs and kernels). And as buhohitr said, rooting in itself will not do anything to alleviate any problems in themselves, except for some tweaks that lessen scrolling hiccups and such to a large degree.
Unlocking, however, is another story entirely. Although you cannot change the hardware choices ASUS made -- and they are the cause of some issues we are/were having -- you can change to a better optimized version of the stock ROM, or an AOSP/AOKP/CM10-based ROM. It will make your user experience that much better.
And something personal... (I've recently been criticized for typically being unhelpful and rude. At leats this tie, I didn't mean it that way.) Please do make sure you get to a good level of understanding regarding the Android basics of flashing/rooting/unlocking, and their differences and implications, and the same for ROMs/kernels/recoveries. The change of the 700 killing itself is probably close to nil, but with a little bit of ill-informed user intervention will do the trick.

unlocking a TF700 voids warranty. Just something to keep in mind if that's important to you. manufacturing defect (e.g. screen not properly glued) won't be covered either even though it has nothing to do with unlocking.

[Q] SD Cards. Good or Bad?

Hi,
I have an unlocked Razr HD with expanded external SD of 13 GB. I just use it to store media files, mainly songs, some movies. All apps are in the internal memory. Since I flash roms whenevr they arrive, I find it convenient to store my files in the external disk so that a swipe will not remove these.
A friend once told me that just having the sd card increases the load on the motherboard and decreases the performance. The performance takes a hit. Also, the life of the phone diminishes with time.
Since I have 32 GB inbuilt, I am wondering if I should ditch the external one, if its really that bad. Any suggestions?

I would like to know where your friend got his information from. It decreases the phone's lifetime? Now, if you write to an external SD card frequently, it will cause the SD card to eventually fail, but that depends on how much writing you do to it. Since you are just storing media, you should be fine.
But, an SD card will not cause the phone's lifetime to diminish.

With 4.2(?) the defragmentation feature "fstrim" was incorporated.
If rooted you can use the apk version.
Not having it is the reason new phones have worked better. Reformatting & copying files back is the only way to get defragmentation w/o fstrim.

solid state drives and similar (sd cards) never need defrag, in fact it reduces the life span i believe.

this "it has the associated drawbacks of increased write amplification and wear of the flash cells" is consistent with what i have read a few years ago, as i have been using ssd's for a good 4 years or more on pc.
i wasnt aware of the "trim" feature in pc or android, but it does sound beneficial, however still seems like it will reduce life span by default.

[Q] Encryption Speeds

Has anyone encrypted their memory and SD? If so have you noticed any effect on speed/battery performance?
I'm thinking of encryption as I work in a profession where I have sensitive health info about patients sometimes stored on my device and want to cover myself legally.

I have. I'm thinking of doing it again just so that no one can plug into my phone and scan it (ie cops/tsa). If you reset your phone, which I did, all encryption is removed. I did not notice any slow downs or anything like that. Plus, my phones not rooted so I'm not really sure I want my sd card encrypted as I wouldn't be able to take it out and work with it. It's mostly the phone and its information that I would be worried about.

I'd second that. Here's why.
