Memory Card = SLOW Phone

Hi, I just want to see if this is a common problem or it's just my memory card. I bought a 16GB card from Newegg to hold all my music and whenever the card is actually in my phone, (Flashed to EnergyROM Geneis), it is SLOW. Lagging everywhere, almost useless and occassionaly after long hours will give me a "emergency low memory" error, and I will have to reset by taking the battery out. When I remove the card, after a few minutes the phone is MUCH faster, it still lags a bit, but definately useable, and it's just very smooth compared to the jaggy and stiff movements when the card is in.
Whats up? Thanks.

naa, i wouldnt say this is normal mate, prob a duff memory card, try another one and see how it goes.... i have noticed a slow-down on mine when i use my storage card to save all my emails , but apart from that, no difference card in / card out.

Come to think of it.... I may be having the same problem.
About a week ago I installed 3 new pieces of software. After a few days I noticed that my phone has been feeling laggy. So 1 by1 I unistalled the software... still the problem persists.
Reading your post made me think... hmm about a week ago I also installed a 4 gb memory card! The card works fine, I can access it, and store stuff on it.
Also, come to think of it. I was making panoramic photos last night and my phone kept freezing after the 2nd photos. And would crash- resetting itself. I had the phone set to save images to the card. Setting it to save them to the phone it stopped crashing... maybe my memory card is too slow. Perhaps, there is a setting in the phone which affects the through put from the phone to the card that can be tweaked. I seam to remember see settings for power saving features for the micro sd card.. Could this be the culprit?

my well-used card made my tp2 quirky so i reformatted fat32 in vista and all is good.

maybe there is so much songs in your card.
or your card speed is slowly.

on screen keys, usb otg, and some questions

im currently a gs2 user, very happy with it, but my father wants to grab it from me, plus i can buy a gnex from a frd of mine bnib for a very good price, so i think im gonna switch, a few questions:
1. since the gnex doesnt support external sd card, and i read forums here it wont support usb drive with otg cable, but if rooted, is it possible? what app should i use?
2. i dunno y only gnex doesnt have hardware home (and back and menu) keys, is it annoying that first, the on screen keys consumes some screen real estate (say more dev are writing apps for 1280x720 screen, but software keys consume 64x720 pixels?), and second, would it cause some problems using some full screen apps?
3. tried playing my frds gnex, compared side by side with my gs2, even with different screen resolution, gnex hd screen doesnt show more stuff than my gs2 screen except maybe browser, would dpi mod fix that?
4. is there such a folder called "sd_card" like in my gs2? if not then i lose everything everytime i flash new rom?
thanks in advance

1. its very much supports usb otg, with the cable and root. i got my cable from amazon for about $4. the app i use is stick mount. ive sucessfully connected a 32gb sd card, my kindle fire, and my professional digital camera, as well as a usb mouse and keyboard.
2. with the soft keys being on the actually screen, the usable screen size comes out to about 4.3 inches. the reason the sg2 looks like it can fit more is the width of the screen is slightly more than the gnex. apps do not hide the soft keys and i find that i personally have never hit them, however, videos such as netflix and youtube WILL go to full screen and hide the buttons. a simple tap of the screen will bring them back into view.
3. read number 2 and sorry but i dont know much about dpi resolution. i just know its brillantly beautiful either way.
4. there is a seperate partition on teh internal memory labeled as such when it is plugged into a computer as a media drive. as far as i know now method of flashing will wipe this partition clean minus one of the tools required to flash the android revolution hd rom. this is the only problem i have with this phone. it takes FOREVER to transfer anything to or from a computer.
i hope this helpshttp://media.xda-developers.com/images/icons/icon7.gif

You can attach any hard drive via USB as long as it has an external power source, like Mwinggg said you need an OTG cable and Chainfire's Stick Mount. Again, like Mwinggg said, you can also attach a mouse and keyboard.
I've not tried changing the DPI using something like LCD Density changer since I've had the Nexus, you really don't need to. But if you want to of course it will work.
The internal SD card, or 'virtual SD Card' won't be wiped when you flash a new ROM or hard reset the phone. It works exactly the same as the internal SD card does on the SGS II.

thank you both of you, that clears up all my questions
yea i have the otg cable, i love how i can plug in the usb drive from attached to my key chain when needed, i will need it more if i go for the nexus since i have a 32gb msd card in my gs2 which nexus doesnt support

Is my xperia play fixable?

I bought a used xperia play and it works and looks decently nice, however the speaker doesn't give out sound, I tested it using the service code on the phone (*#*#7378423#*#*), nether the speaker or stereo speaker (in the service test mode) give out sound, whats weird tho is that yesterday i was playing the installed tetris game and it had sound but today i tried it again and no sound, also the phone does give out sound when i go in the sound settings and adjust the volume of ringtone and alarm. this issue looks like it can be easy to fix (but i dont know for sure).
Now on to my main concern, the xperia play wont recognize the micro sd card i bought new (32gb c4), i have researched this issue extensively because without the micro sd i can't really do anything with the phone (gaming wise) and i know the back cover has to be properly placed because there is a little white switch that needs to be pressed by the cover. the cover is placed correctly but the phone wont do anything, its like there ins't anything inside the sd slot, it gives me no massage at all and I fear the sd module is damaged. i looked inside the sd slot and i can't really see anything strange about it. I now the sd card is not the problem because today i tested it on my friend's xperia ray and it work perfectly (it also works on laptop, in fact i formatted the memory to FAT32 with the allocation to 32 bits, stander stuff here), i'm really hoping this is a software related problem, i say this because when i wanted to restore the phone using the update service program from sony. had to press the back button while connecting the usb and then update service gave me the message "the phone has a modified firmware and can not do restored" or something along those lines.
the person whom i bought the phones says he was restoring to factory when in the middle of the process the battery fell out and then when he turned it on he would only get the sony logo, that sounds like total BS but i went with it anyways, so we went to a place that fixes phones and they got it fixed in an hour and they said someone tried to install a custom firmware but failed and got it in that state (im guessing they just downgraded the phone) but in the end i got a good deal, he paid for the repair. so here i am in the xda forums, my last resort, i already asked in the sony foums, sony's twitter support team, and no one has answered me.
So, to make things short, i need help installing the original firmware and bestially restore the phone to its legit state in hopes of getting this fixed, and if that doesn't work, can anyone point me in the right direction for repairing the speaker(s) and the micro sd slot module?
like i said, everything else about the phone works great, wifi, bluetooth, touchscreen, vibration, buttons, everything but those two things work, also im new to android but i am not a noob, ive jailbroken iphones before, tweak the system files, unlocked it, etc.
P.S: i turned the phone off and then on and tried tetris again and now the sound works, can someone explain this to me?

OTG / Stickmount sleep mode question.

I have been using an OTG cable (which was not specifically purchased for the N7 - I had one from another device) and Stickmount to mount an SD card reader w/ SD card loaded with videos to view. This, generally, has been working fine, but yesterday I encountered a situation where, while trying to watch something, I was continually interrupted for several minutes at a time. Of course the N7 went into sleep. When I woke it up, I noticed that the SD reader (which has a power./activity light on it) did not get repowered. To restore it I had to unmount it, pull the OTG cable, then reconnect it.
While not THAT big of a hassle, since I was continually getting interrupted yesterday, I was wondering if this is normal behavior for N7/OTG/Stickmout.

Ok, this is a bit strange. I replaced all the hardware components (excepting the N7 itself, of course) -- new OTG cable, new portable SDHX/SDHX Micro reader and the card and it is doing the same thing. The reader has a power light on it, that remains on when it is in use. When the N7 times out (I have it set for 2 minutes), the light on the reader extinguishes as well. When I wake up the N7, the power light on the reader does NOT come back on. Stickmount reports it is still mounted and I can traverse the tree to get to it with a file manager. However, when I try to access anything on the card, it errors out.
I repeated the test with a standard USB drive (a rather small one that would not do for what I am trying to accomplish -- media storage/play to save on space on the internal "SD" card). When the N7 timed out, the light on this unit remained on. I was able to wake the unit and continue on accessing the flash drive without issue.
What the heck is the difference between a portable reader with an SD card in it and a flash drive. And, is there anyway to get the reader to behave like the flash drive.
If anyone has any insights into this, I would appreciate it!

At the point where the light does not come on, I would test removing and replacing the media in the reader. Curious if it then works.

Nope, light doesn't come on, card is not readable. Thanks for the suggestion, though...

Interesting. This sounds like the software loading the drivers for the reader are not working. Each version (over the years) of Linux has different ways to mount USB. I am not sure which method Android uses, so I am not much help. Probably someone on XDA knows the details if they will contribute. Or, you might get support from one of the popular Android OTG media sharing app makers to help explain it.
Have you tried a powered (and/or) non powered USB hub in the middle? Curious if your results would be the same.

Unfortunately I don't have one. I NEED to get one, but not yet.

Yea, I noticed the same problem when I was using android vlc to play videos from OTG mounted stick. If I paused and went away for a while, it couldn't resume when I came back. MXPlayer works better, but only because you can start playing the same video again and it will ask if it should resume where it left off, so at least there is a way to get back to where you were after remounting the stick.
If I copy the video file to the local /sdcard storage, none of these problem with sleep crop up, so it is definitely OTG that goes funny in the head.

[Q] How to know if SD card is the cause of random reboots?

Well it has been asked many times in this phone's section why it reboots. Somewhere I've read that it might be the SD card. I got Kingmax 16gb class 6 Micro SD hc card, and I've noticed after I install some ICS or the "official" 4.1.2 jelly bean it works fine at the beggining. After I put the music and pictures on SD card which take about 4gb space it continues to do well for first few hours (once even a whole day) and then it suddenly restarts. After that first restart the phone starts restarting more frequently like 3-4 times a day, and it annoys me. Is it maybe the SD card problem? And is there any way to check it?

remove the sd card and use the phone without it, if it still restarting on its own . The rom you're using is the problem

Thing is I often need the phone, and it has low memory on its own, that is why I didn't use that method

The method is for troubleshooting lol (-_-") , if you didnt try to remove the presumably and have a go you wouldnt know what is actually faulting

Well I did remove, but I didn't use it for more than 2 hours like that, not a whole day.

Try another memory card with different class
And play song on third party apps like google play music or poweramp etc..
Try memory card on different phone & check memory card is damaged or not
Dump the memory card on water (do it your self i am not resposible for any damage) dry with clean soft cloth
If not working this method
Reset your mobile
Flash your mobile or goto service center
