I'm a student. I don't take good care of my phone. I was at Starbucks yesterday with my friend who has a HTC Inspire 4G (basically a Desire HD with a HSPA+ radio) and after seeing how I handle my phone at my home (throwing it on my bed when I Need to do something else, tossing it onto the ground when I need to pick something heavy up, etc.) he was amazed how his phone that he takes extreme care of is scratched and broken and mine is pristine.

Goes to show you how badly made these HTC phones are.

I use my phone as a Speedometer / GPS on my motorcycle. The camera is the only exposed part of the phone on the back. It's taken stones and bugs full force at 100kph+ with only minor scratches on the bezel. The phone is very tough. :laugh:

My phone fell out my pocket flat on its face onto tiles... No visible damage but the screen never came on again. Take care of your phones and dont drop them they are not nokia 3210s :P
[Galaxy S II General] rakeshishere:
Your phone fell and nothing happened? That's coz you're lucky.

It's nothing to do with Galaxy s2.

accidentally dropped my phone a couple of times even without any protected casings and so far just one small dent on the top left corner. While the phone is built very plasticky, I still think it's a strong protected phone overall. No scratch whatsoever on the screen either, well built!

I recently bought a Galaxy S II I was using my phone for navigation then suddenly it flew out of my hand and dropped on the concrete foot path and screen cracked but works flawlessly. It happened after two days I bought my phone. :(
[Galaxy S II General] King_Rat:
:doh: it was an accident :lmao:

:mmm: smoothies

I'm one lucky SOB :aight:

I've dropped every smart phone I've owned one time or another :yup: & not one of them has scratched/cracked/chipped etc.

-=or=- maybe... just maybe... they're actually designed to fall out of hands & take a bit of punishment...

Like saying if you drive an SUV and crash & come away w/o any injuries - it's got nothing to do with the SUV! You're just lucky? :sif:

PS - thanks to those sharing their stories both sad & happy :cool:
[Galaxy S II General] distilicious:
Mine took quite a few falls not long after buying it. the first was the worst. Slid right off my dresser. my heart stopped as i watched it go face down in slow mo. i was afraid to pick it up. When i finally did it was fine and not a mark. Bought a screen protector kit that day and walked a with a little more confidence knowing this thing is pretty damn tuff. win.
[Galaxy S II General] shd_66:
Dropped mine twice.

First time i was taking it out of my pocket to awnser a call while riding my bicycle(had forgotten my headphones that day) and it slipped out of my hand and hit the street at about 25km/h. Back and battery popped right of and when i picked it up it only had some minor scratches around the edges and booted straight up after putting the battery back.

Second time it slipped out of my trousers pocket while i was getting up from the sofa. Dropped about 40 cm onto the hard wood floor screen down. Destroyed the glass and screen completely. Locked liked somebody hit it with a hammer. Had to get the screen replaced. Just shows you how lucky one can be sometimes and sometimes not.

SO what is your recommended solutions to use the memory efficiently.

[Android General] stempox:
I can not answer, because to judge even approximate because it depends what kind of applications you have installed in your phone, however I think the tutorial explains well why and how to act on the applications in use ;)
[Android General] pakdaman:
When I go to the home screeen, it takes some time to reload my application icons and I thought it was related to a bunch of applications running background.. so I was always stopping services that I mostly not used, but according to what you said, I'm causing the system instability, yes?
[Android General] stempox:
is very likely
[Android General] jbctiong:

The most simplest option is to remove all bloatware. Those are really a mess which keeps restarting and eating up RAM even after they are killed.

Or just add ".bak" extension to the apk using RootExplorer incase if u will ever need it again. I did the same.

[Galaxy S II Q&A, Help & Troubleshooting] jamiejohnson:
Hey guys,

I currently have a Galaxy S2 and been looking to root it. although i want to save my current kernel which is stock to the phone just incase it goes wrong and i can put that back on.

I have read numerous posts on your forum but iv not entirely understood how this is done (maybe too many 'tech' words for me).

Also is this even possible to recover the original kernel from the phone in any way because i have looked for the original kernel on SamMobile and there is nothing there that is close to my kernel.

If it helps im in the UK and on T-mobile network.

Hi,

I'm new on this forum and hope I can get some help here.....

I own a ASUS TRANSFORMER TF300TG and what I'm asking is:

1. As the TF300TG has a Bluetooth is it possible to pair it with a phone and use it as a phone (somethin like a combination with phone and car audio)

2. As it has a sim card slot (used fot data transfer) is there any chance to use the TF300TG as a phone?

At least point 1 would be nice to make it work:confused:
[Eee Pad Transformer General] Novarto:
The same Question

Hey I've got the same Question about my TF300TG.

I already recognized that it is possible to send and recieve SMS, and what is maybe interesting: I also called the number of the inserted SIM-Card, but while ringing on the phone from which i called, nothing happend on the tablet... but when i hang up the tablet opened the lockscreen ?!

Is it maybe possible, on an easy way, to extract the phone.apk and other necessary data from another ICS image?

Thanks for your help!

[Asus Transformer TF700] tha_kreature:
I've been at it back and forth with Asus and SanDisk support now as I have yet to get my SanDisk Mobile Ultra 32GB UHS-1 card to work properly in the TF700T.

First card worked erratically and died completely, second card doesn't work at all.

The log of the tablet sais read errors but the card work perfectly in both PC and android mobile (x10 Mini).

Tablet sais it's DDR so I assume it uses DDR50 mode which is the most complicated mode to use due to the data timing.

Has anybody else got a UHS-1 card and had it work reliably in the TF700T ?

When mine was working I was getting sporadic read errors causing copy file from card to device to fail, and video to stutter.

(File copy was aborted by "paste files failed" message.)

These cards would offer much improved io performance vs a normal card and their improved latency should make em improve responsetime too.
[Asus Transformer TF700] tha_kreature:
I popped by a shop today and tested the UHS-1 card in a TF300 too. It got a hissyfit and went into a mount-loop.

Bought a SanDisk FCS-HS3 UHS-1 compatible USB3.0 reader to test the card on a pc and it performs great. (Well writes are within class 10 spec, and reads are fantastic.) See attached Atto run.

Also got a 32 GB Class 10 Lexar card to see how the TF700 likes it. No problems and everything seems smooth.
[Asus Transformer TF700] d14b0ll0s:
I have Sandisk Ultra Micro SD SDHC UHS-I 16GB Class 10 30MB/s and it's been working fine so far, it even rescued me when I needed a firmware update after bootloop, only with lower write speeds than SD, USB disk or internal memory (somehow I get somewhere near ~10/20 W/R on internal and ~20/10 on SD, pendrive, USB HDD etc., btw, seems a bit strange to me, as I would expect it the other way around).
[Asus Transformer TF700] tha_kreature:
That sounds like how my first card performed. Not fast.

I wish the SD test apps could show a graph like HD Tune on pc. To see how smoothly the card operates.

I know that any errors are masked by android and it resets card and continues thus making a card that hang all the time just appear slow.
[Asus Transformer TF700] d14b0ll0s:
It is not about UHS-1 though, I get the same with USB pendrive or HDD.
[Asus Transformer TF700] tha_kreature:
This is the same test on the same card in a NON UHS-1 reader.

As you can see the readings are drastically different.
[Asus Transformer TF700] d14b0ll0s:
Sorry if I'm missing something, but on your screenshot I see 19 MB/s read and 9,5 MB/s write on average on your PC, so how is that different from what we were discussing as the speeds we were getting on the tablet?

Edit: I see your earlier post showing 40+ MB/s read speeds, but this was USB 3.0, wasn't it.

Edit: I forgot we were discussing

micro

SD speeds. If you get 19/10 on your PC, this is in fact 50% more than I'm getting with microSD on the Infinity. It surely shows a major difference.
[Asus Transformer TF700] tha_kreature:
Yes, USB3.0 with a reader using UHS-1. The UHS-1 is the most important part as that increases the bandwidth between controller and card and also reduces some delays on completion etc.

On the tablet I was getting good speeds and then pauses/breaks getting the average very low on old card. Log showed errors. New card doesn't even mount.

Edit:

It does however show how the tablet is trying to moungt it and what speed it talks to it, also what capability it has.

Edit2:

USB 2.0 can do 40 MB/s too btw, but usually max 30-35. The UHS-1 makes the difference.
[Asus Transformer TF700] d14b0ll0s:
For bigger data transfers I'm actually relying more on full-size SD card in the dock or USB disk. Which is of course a possibility only if one is carrying a dock..

---------- Post added at 05:56 PM ---------- Previous post was at 05:54 PM ----------

Yes, there is no question we have the lags to blame. My microSD writing speeds start with 30-35 MB/s for a few seconds (which is a lot more than I'm getting on my laptop with this card), then the lags make it drop even to 6 MB/s. So these are all the I/O issues we were discussing in so many threads here. Not much will come out of further benchmarks until we get an update (JB / kernel / smaller firmware fixes / hopefully anything)
[Asus Transformer TF700] tha_kreature:
Untill the 17'th I won't have access to any docs...

Attached is a shot of the dmesg output from where it detects the card.

Notice it registers it as a ultra high speed DDR SDHC. DDR must mean it is considering using the UHS mode DDR50 which is a complicated mode requiring calibration. It also seems to assume/try NTFS first.

I can't see any attempts of uing card in normal SDHC mode after the UHS failing, nor any normal non DDR UHS modes.
[Asus Transformer TF700] tha_kreature:
I'd like you to scour your dmesg log after one of those glitches, and also after inserting the card to see if there is any significant difference.

My card dipped in speed but usually did not log errors. I think the first retry is not logged if successfull.
[Asus Transformer TF700] d14b0ll0s:
I don't get any errors after (re)inserting the card apart from those from tntfs saying the boot sector is invalid, so it's quitting after finding out this is not NTFS (because it is FAT32 ;>).

Tell me what errors do you get specifically, so I could grep my logs looking for them.
[Asus Transformer TF700] tha_kreature:
See my attached pic.

See how it identifys card ans ultra high speed ddr.
[Asus Transformer TF700] d14b0ll0s:
Sorry, I missed the last post on the previous page.

Doesn't look good, I don't get any of these in my logs apart from the NTFS assumption, which might be the normal thing (a late attempt to solve the NTFS compatibility issues).

I would try sio if I were you.

Mine doesn't say anything about ultra speed DDR SDHC however, it only gives the "new high speed SDHC card" output..

I'm not sure what you mean by saying that it doesn't treat it as SDHC afterwards - where would you want to have it reported?
[Asus Transformer TF700] tha_kreature:
Your card works as it does not infact support UHS-1. It's probably one of the "Ultra" cards not "Ultra UHS-1".

The difference is a small U on the card with a 1 in it. (See attached.)

Sandisk has the same card in identical packaging, except for the UHS-1 support. The difference is drastic on PC, and apparantly catastrophic on TF700T and TF300.
[Asus Transformer TF700] d14b0ll0s:
See my logs attached.
[Asus Transformer TF700] d14b0ll0s:
In fact, mine is not UHS-I, but regular SDHC, sorry about misinforming you, I was initially thinking about getting the one you got yourself and then misclicked on the auction, LOL, I can see it now, bummer! I think it's even class 4, not class 10 (how much slower can it be because of it?). My full-size SD in the dock is UHS-1 and it's been performing well (Sandisk Extreme 32 GB 45 MB/s class 10).
[Asus Transformer TF700] tha_kreature:
Thanks. Definately a non UHS card.

So far I've found or read about Sandisk Ultra in these flavour:

- Sandisk Ultra XXGB Class 6

- Sandisk Ultra XXGB Class 10

- Sandisk Ultra XXGB Class 10 UHS-1

- Sandisk Mobile Ultra XXGB Class 6

- Sandisk Mobile Ultra XXGB Class 10

- Sandisk Mobile Ultra XXGB Class 10 UHS-1

The packaging on my card sais SanDisk Mobile Ultra but the card sais only SanDisk Ultra. (First card said Mobile Ultra.)

It's really odd how there is always differences on pics I find.
[Asus Transformer TF700] d14b0ll0s:
Yeah, mine is not ultra, terrible miss-click. I will use it in the phone probably and will order UHS-I class 10, unless others report same problems as yours.
[Asus Transformer TF700] tha_kreature:
Could you insert it and check the log?

See if it does anything different on it vs the other?

Unless it has any U on it it will probably only do standard SD speed of 50 MHz givingv 25 MB/s max datarate.
[Asus Transformer TF700] d14b0ll0s:
It seems the SD cards in the dock are handled differently. Log attached.
[Asus Transformer TF700] tha_kreature:
Very interesting!

It appears it uses a USB card reader. Wonder if it's USB 2.0 or 3.0 ?

If it's 2.0 then it will be a bottleneck for the new UHS cards. In fact, it will be a source of a lot more latency for normal SDHC cards as well.
[Asus Transformer TF700] d14b0ll0s:
Not sure how to check it. Writing speeds in the benchmarks start with 45MB/s, but deteriorate very fast because of the lags.

Edit: Actually it started with 70MB/s, but after writing 500MB/s it is somewhere between 25 and 20, so I'm not sure how much should we take this values for real (in the second test it was 30-25 for a few seconds, these may be misreads).

Edit 2: I think I'm getting punished for saying it's been performing well, I just got a forced reboot while doing the benchmark ;> Twice. Never happened before.
[Asus Transformer TF700] tha_kreature:
Buffering probably...

If your tab is rooted you may be able to use the usb subsystem or some other part to query the USB chain. The ID's will tell you by a google search what they are and if they're usb 2 or 3.
[Asus Transformer TF700] n-j-f:
Yes. Just seen this thread. I responded here.
[Asus Transformer TF700] tha_kreature:
Ar you sure the card is UHS-1 and not just class 10?

They are two different things.

Also, using "Android Terminal Emulator" by Jack Palevich you can run the dmesg command to see the system log data.

It will tell you what the card is mounted as, and also show you if the TF700 identifies it as a ultra high speed card or just a high speed one.
[Asus Transformer TF700] d14b0ll0s:
Reboot could be due to the card being formatted as NTFS I believe.
[Asus Transformer TF700] tha_kreature:
Default format on SDXC is ExFat isn't it?
[Asus Transformer TF700] n-j-f:
The retail packaging certainly says UHS Speed class 1 (and I bought them from Amazon.de so I don't think they're fakes!).

Downloaded ATE and typed dmesg. It looks like 1000s of lines of info. Sorry but I'm new to all this. How do I find the bit I should be looking at?
[Asus Transformer TF700] tha_kreature:
You will need to scroll up quite a bit I expect. In the internal µSD slot there will be a lot of messages from MMC.

The interesting line will be one that sais "mmc2: new ......." and will be start with a <6> as it's a level 6 message I think.

I think the time on the left is time since startup in seconds so you can use that to identify right area assuming you know when you inserted card after booting tablet.
[Asus Transformer TF700] d14b0ll0s:
Don't know, never had one.

I was referring to getting a reboot on mine (see "edit 2" above).
[Asus Transformer TF700] n-j-f:
OK. I rebooted and inserted the card as soon as it finished booting. I emailed the dmesg result to myself and copied it into a Word doc where it was easier to search. I found this -

[Asus Transformer TF700] tha_kreature:
It is definately a UHS card!

And it looks a lot like my first card untill it broke, no signs of error.

Mine gave errors when trying to copy large files off the card and onto internal memory.

Notice your fat is dirty. That could mean that it has had a disconnect/reset earlier.

Could you try copying some data from the card onto for example movies folder on the tablet and then have a new look at dmesg?
[Asus Transformer TF700] n-j-f:
So far I've only got the one file about 580Mb on the card. Copied it to internal storage and it went through without any error messages. The progress bar seemed to stick 2 or 3 times but it carried on. I did a new dmesg but it is also very long. Anything particular I should be looking for?

I see what you say about the fat being dirty. Could that be because on the previous boot I had quite a job getting the card into the slot. It's quite pernickity.It kept popping out until I used a finger nail to push it in.

Wondering if I should unmount and format the card in the tablet. I can't find out if it will keep the exFAT format or change it to NTFS of FAT32.
[Asus Transformer TF700] tommedema:
Do we have a list of confirmed working 32GB and 64GB MicroSD cards? Preferably class 10 (is that the same as UHS-1)?
[Asus Transformer TF700] tha_kreature:
Not yet tommedema.

And a UHS-1 card can be any class although they will most likely be very high as it' snot much point in high interface speed if flash is slow.

So far I know the Lexar cards (non UHS-1) work nicely.

I've tried two Sandisk cards both UHS-1 and one failed, other doesn't work.

Only norm2002 seems to have a UHS-1 card that works in his tablet, not sure why but I still think the calibration or variances have something to do with it.
[Asus Transformer TF700] tha_kreature:
Hmm, you could look for any retry messages.

There could be one or two every time it stuck.
