Hi
I bought a 128mb Secure Digital Card from Expansys but when I put it
into my device the Memory on Storage Card says 118.75mb so
where's 9.25mb gone!!!!!
TIA
Charles
The file allocation table (FAT) eats up the rest.
John
And something about..
Secure Digital - This requires space for the "secureness"
So a Multimedia Card may have given you a few megs back..
Its the old saying.
You just don't get what you pay for anymore!
MmF
Missing 10mb
Thanks for the responses.
9.25mb for the FAT, Jeeeez!
Why don't they build them 138mb, and give me what I've paid for!
Rgds
Charles
Actually the FAT does not eat up that much space, not even close. Here's the other part of the reason: A megabyte and a million bytes are NOT equal!
A kilobyte is 1024 bytes. A megabyte is 1000 of those.
The card and hard drive makers say that THEY measure a megabyte as being 1 million characters even. So your 256MB card can hold 256 million characters or bytes.
The computer and PPC however, measures in real megabytes and take that number, dividing it by 1024, to come up with its reported size. Therefore, your card has 256 million bytes, but not 256 megabytes.
They've redefined the word.
Ahh I see now. Thanks Carlos

So we all know the Thunderbolt was advertised in having 8gig Internal and 32 External (microSD)
So many posts have I seen with so many misleading and different responses to of which HTC is confused themselves. Some say it was a misprint and there is only 4GB Internal others say there is 8gb.
Id like to post this output via a df command.

So Im not sure how Flash Memory works if its like regular hard disk there "Could" be some available space not added to the Partition. But im not very knowledgeable in that area..
I work with AIX servers all day and just knew a couple of places to look for diskspace. And im siding on the fact that we indeed do not have 8GB eMMC We have a 4GB Internal eMMC.
Anyone else got something I Missed? Or hopefully a Correction to what ive found?
Scotty2 said it is indeed 8GB but it is formatted down to 4 so it is less likely to fail. He said something on his twitter @scotty2walker

Those folks there have some good points. Verizon for the longest time advertised it having 8GB internal and 32GB MicroSD
Makes a person to think they got 40gig of space.
Now granted Verizon worded everything "very" carefully and never said any of it was available to the end user lol.
Im just curious if for just my own sanity. if there is anyway I can prove for myself the size of the eMMC. Im a guy who has to see it for myself to believe it.
Yea same here, setting up and tonight. New to Droid but am quite comfortable in *nix land.

This is exactly like what happened with the G2. The actual chip is an 8GB chip. The part number from a tear down or from the command you can give a rooted device to tell you the part numbers, will likely return a part that is 8GB.
The formatting is done in such a way that the NAND is only left with 4GB of usable space, but it is much more robust and will last a lot longer.
It is a good thing I think, not a bad thing.
They can advertise it as having 8GB internal memory because the part number is an 8GB part. It could also be a miscommunication between Verizon and HTC.
When it happened with the G2 T-Mobile seemed clueless......

Has Verizon released a press release or anything identifying this yet? I know there are many people upset over that. Im not.. I rather it be formated SLC.. But It is something a customer would take into account when Purchasing something when they says it has 8GB been nice to say that only 2GB was usable lol
This clears up some of the confusion I had about all this.

^This, thanks OP and others. I was wondering if we got screwed or if there was just 5G's of crap preloaded... Either way we got screwed, and yes promotional material in the stores on launch DID say 8GB internal so....
according to verizon the phone takes 5.5gigs for android alone.
I asked this in another forum. Got the same in response. No bueno HTC.

Hi,
I am creating (*ehm, trying to) a networked game and I have just started to test it on my Samsung Galaxy SII. As it is a networked game, obviously, I needed one more handset (it's a HUAWEI U8510). The interesting thing is that the network latency greatly varies between the two handsets, albeit being on the same WIFI network. Both handsets have Android 2.3.3.
When I ping my Galaxy SII from my laptop, i get the following times:
Code:
PING 192.168.1.108 (192.168.1.108) 56(84) bytes of data.

The HUAWEI, on the other hand gives much better values:

Any ideas, what could cause the high latency on the Galaxy SII? The Phone was as much idle, as possible at the time of the ping. Is it some kind of WIFI sleep mode, or bad network driver?
Update: the previous measurements were done on KF1 (Frankenstein) firmware.f
IN there I managed to lower the latency significantly using the WIFI State Lock in android (using the "PERFORMANCE MODE"). If you do this, you receive:
DEBUG/WifiStateTracker(2707): high performance mode: true
Two days ago I updated to KF2. While you can still enable the high-performance mode (you see it in LogCat), the latency is not reflecting this change when you ping the station. KF2 delivers the majority of the pings under 5ms of latency, which is great. There are still some pings over 50ms though (and some over 100ms), but nos as much as before.
However, I am wondering - isn't such well-performing WIFI eat more battery?
Slightly separate however having migrated from the HD2 running android and internet speed seems slower on the SGS2.
The initial connect seems slow. 15 secs latency. The HD2 was almost instantaneous. Eg side by side with an iphone it was way quicker.
The SGSII is a lot slower than the iPhone 2

Hey there guys!
i got a new tv which supports miracast.now is my problem,as the title already tells,that my s2 isnt supporting it.
is there a way to port it to the s2?or is there a app to make it possible?
Thanks a lot
Really no answer? Cant anybody tell me if its possible???
i don't know correct answer, so i told my works.
S2 on 4.2.2 and miracast didn't working.
when miracast process start on S2, then S2 occurred eternal reboot loop!
i think exynos4 couldn't miracast, exynos5 such as Nexus 10 can miracast.

From what I have read is not the procesor that is important, it's about wifi direct. So I what I meant was that both phone have the same wifi module that support wifi direct.
Sent from my GT-I9100 using xda app-developers app
yes, s2 supported wifi direct.
IMO also important hardware h.264 video encorder for miracast.
i don't know s2's encorder satisfied miracast specification.
Sent from my N-03E using xda app-developers app
GS2 is usig Broadcom BCM4330 wifi chip, the same as i9250.
And if you take a look on Wikipedia on i9100 you will find that ..."For H.264 playback, the device natively supports 8-bit encodes along with up to 1080p HD video playback."
So, teoreticly it shoud work. Maybe you have to modify the encoding rate, but I think there is a chance that it will work.
@s107ken Do you have the miracast patch installed on i9250? I see that you have a GS2 too, have you tried implementing the miracast patch to it? Do you think that the screenrecording patch will work on i9100?
I'm actualy trying to use my phone for watching movies, and I really don't like the fact that you have to connect your charger to a MHL cable. And I was thinking, if it's possible to reduce the brightness to 0 (off) when the phone is on miracast connection and to turn it back on primery state once you exit the app/option. This way you can save the battery. Do you think it's possibile to do that?
Thank you.

I have a nexus 6 and a galaxy s3 here which have variable ping times. Tried with several routers and ping times are quite high, at times they are so high that some games are unplayable or the phone drops packets once in a while. Below is the information I posted to google product forums and well, I got a canned response unfortunately. Also it was suggested that the problem may be hardware related, but I saw this problem also in 2 samsung phones and my nexus 6, at least 3 different wifi routers and I am not sure if I am ready to call it a hardware failure. I ran the tests just after flashing MMB29Q firmware so the phone was mostly stock at that point. (I setup few google apps and store only). I would be happy to know if somebody knows the reason for this.
I am trying to figure out why my nexus 6 (MMB29Q firmware) is behaving so badly on network. When I play games which require realtime data, sometimes games freeze for a second or two.
I have 2 phones next to each other Nexus6 and chinese Otium S5. From inside my wireless router (OpenWRT) I ping both of them, here is how it looks like (sometimes nexus 6 loses packets also)

I tried
* factory reset and reset network settings in nexus 6 and it does not help.
* I found in some forums the location settings may caused problems in previous rom so I tried to enable things like keep wifi always on, use wifi etc. for location and some other combinations but it does not help.
* I tried another access point. (tp-link with tp-link firmware) and it does the same problem.
* I tried to go next to the access point, (1-2 meters away line of sight) and still it did not help.
* I tried disabling WMM mode in the access point and it made the Otium pings go down to 1.5ms to 2.5ms (about 2ms faster than before. I tried this twice because I couldn't believe that it made a difference)
* On tp-link, I tried 802.11b, bg, bgn, n only etc. Also on OpenWRT the legacy mode which I believe uses 802.11 bg.
Interestingly if I ping from nexus 6 to the router it works rather fine while still slower than the chinese phone.

RIght now when I ran the tests, in chinese phone the wifi strength is -69 to -73 DBM and in nexus 6 it changes between -67 to -72 DBM
In the router I see varying numbers between -65 to -75 DBM on both phones.
I am not sure what other information I can provide right now. If you think you would need more, please let me know how to obtain it and I will obtain and provide it.
Thanks!
