can a slow SD card + Apps2SD cause frequent lockups - G1 Q&A, Help & Troubleshooting

I have a phone I just did the apps2SD mod and I have no idea, what speed the card is.
Well the phone is locking up at random and that seems to be the most probable cause.
Does this sound right? Any other ideas?

NAND vs Heret, & You

I've got a few questions about installing to NAND vs running it from the SDcard with heret, I'll add the answers under the questions once they have been answered
-What's the difference in battery life?
-Does windows mobile unload completely?
-What's the performance difference
-Is there a difference in running memory size'
-Is it possible to switch the install to NAND from SD and viceversa without user data loss

1. It's about the same
2. Yes it's completely gone from your phone.
3. It's faster from nand
4. no
5. yes
I get much better battery life on nand. better than wm. maybe its just me.

Same here, except when i use a 2.1 build, they drain my battery like crazy. But MYN's donut gives me way better battery life than any wm rom.
that's cause they still haven't quite perfected 2.1 yet. but myns build is near perfect! and the speed on nand is amazing

more like definite battery improvement!
my phone actually lasts a whole day!
WITH heavy phone usage
but now that opera mini 5 is on the market.
the battery should last even longer now
no more having to load a whole page
just images of the sites! haha
The only thing that I would disagree with previous posters is on the speed issue. To me this is all dependent on the quality of your SD Card and your setup.
With a class 6 SD card (even without partitions) I saw little difference in speed when I flashed to the NAND, OTOH I'm sure people with slower cards saw vast improvements.
Getting ready to go to NAND...
I've been running from my SD card for several months and now getting ready to take the plunge by installing Android to NAND.
Questions...Once you install to NAND:
1) do all Apps get installed to NAND or can some get installed to SD?
2) I assume that you can still reference music and other files on the SD card?
3) Are there any drawbacks to going to NAND? Wiping windows from ROM is not a concern.
Looking forward to NAND.
Thank you for your advice!
i made the switch from sd to nand last week, and boy, what a difference!
battery life:
i used to get about ~12 hours with sd, with no data, no browsing, and limited texting
with nand, i have synchronization turned on for both gmail and work email, do tons of browsing, games, and making calls, and still have ~70% after 12 hours
stability:
my phone used to freeze up about once a day (sometimes up to 3 times) with sd install, since nand install, i haven't had one freeze up
definately worth the switch to nand!

Great! Getting ready to unlock my phone.
there should not be a significant battery difference nand vs haret IF you are using the same kernel. I suspect that people who note the difference changed from an older zimage kernel to a newer NAND kernel (.nbh), as there were significant battery improvements in the last 3 or so kernel updates. i agree with other posters that you probably won't see a significant difference in speed if you are running a fast sd card, maybe a small one.
i personally use nand, cause I have no use for win mo anymore.
I have to disagree with the others. I used the same date nbh as zimage and after flashing I get about 6 more hours of battery. and I have a good sdcard. on startup it even says [new high speed sdcard installed] my old 512mb card never said that. so I do have a really good sdcard and again, after flashing, its much!! faster!!!
has anyone had issues with loosing connection to their service provider with a flash? I'm on verizon and doing a hard reset on the phone has made me loose my information and have to call to get it reset up before. If that happens we have to flash back to winmo to fix it?

I'm on sprint I have that problem only if i flash to stock winmo then out to another rom without loading winmo, letting customizations run, then making a data connection, if i do that then flash then i have no problems. But i can flash from rom to rom with no provider data loss
Sorry to revive an ancient topic . I'm really thinking about making the switch from haret to NAND but I would really like to keep my data. The second post in this said that you could keep your data. Is that true? If so I'm flashing it tonight!

1. All apps do get installed to the NAND, and you can move some apps to sd in the applications settings
2. Yes, you can, altough i haven't had much luck with video (maybe because my sd is class 2? it plays for 1 second and then freezes, but sound still goes, and when i try to push something, it force closes)
3. NO DRAWBACKS WHATSOEVER please go with froyo

Install programs on storage card or device?

Hey guys,
Just a general question here. I always installed my programs on the storage card and never the device whenever I had the option but then I wondered is there a difference in terms of speed or anything? Are there certain programs I should be installing on the device and not storage card?
I did a search and didnt find anything.
Thanks
I dont think speed is the problem. I have never encountered any noticeable difference in speed. But I certainly had some stability problems with apps installed onto storage card.

Most of the time the read/write speed from storage card is sufficient to make the app run well from the storage card.
But because the storage card is controlled by a driver the stability can be a problem. I've heard from several sources that an on the storage card installed program running in the background can cause SoD's.
storage card is better for "storage" as applications use the main board memory better...
hmm ok, ill keep that in mind.
My xperia is randomly shutting down by itself for no reason, so Im wondering if thats a problem.
Ill just have it in my pocket and when I press the power button, instead of coming out of standby, it actually starts up.
Sometimes too when it starts up and it shows the sony ericsson screen it will just shut off there too.
Generally I recommend you the following: Don't install system relevant programs onto your storage card. By system relevant I mean all programs that are autostarted or otherwise associated with the os. For example today plugins, programs that replace certain native applictations like messaging etc, task managers...
By following those rules I have no problems at all with unstable applications.
when in suspended mode sd interface is turned off so programs running from there will not run

Swap on a class 2 card worth it?

I've noticed that my G1 (Running CM6) tends to run out of RAM fairly often, I was thinking maybe having swap space might help me a bit with this, however I only have a Class 2 SDHC Card (16GB), would I see any performance increment or should I just wait until I can afford a much faster one? (eg. The Kingston Class 10 one)
I would suggest to use no swap at all ... if RAM is too low, try to enable compcache it will help you probably a bit. I noticed a massive performance drop when enabling swap on CM6.
Sent from my Htcclay's Superfly G1 using XDA App
Swap and CM5/6 don't get along. The memory killer in the kernel thinks that swap is actually free RAM and keeps more things open, stopping tasks from being killed at all. If you want to use swap, I recommend you use a donut/cupcake/hero rom that uses a different kernel so that things don't get down to a screeching halt. And anyways, the fastest speed I have ever seen my phone write something from my computer to the phone via USB is 2.7mb/s, compared with 6-12mb/s I get from an sdcard reader. That means that even when your phone is writing at top speed, it is just barely far from the 2mb/s write speed guaranteed by a class 2. You will definately see better performance with swap on a class 4, but anything higher won't benefit your phone much at all, unless you regularly transfer large amounts of files to your memery card via a card reader.

Compcache didn't improve performance at all, for me at least.

What if I have a task killer app? Because running out of RAM is just as bad as having too much running...I don't have many apps as I only keep what I actually use as well.
I have to ask, what are you seeing as the symptom of "running out of ram" the system will always use all ram so it will always have nearly none free.
By this I of course mean what is taking forever from you the end users perspective.. from there we can tweek in the right direction or work on making the phone prioritize what is needed to be useful.
Many times people put tons of swap only to find the the problem application is still removed from ram/swap due to configuration and the system is even slower with swap.
Also before enabling swap try the settings -> adw -> system -> system persistent is enabled. (Or equivalent on other launchers)
If you really want to try swap, it wont be fast but in very little amounts

Well, if I have MSN Talk open, the home screen tends to fall out of memory (Yeah, I have System persistent enabled) and Messaging is extremely slow (To the point where a letter appears a good second after I press the key), it's that kind of thing when I run certain programs, it makes it hard to have stuff like JuiceDefender running because I always run out of RAM even just running the Speedtest app then.

Declining internal SD performance

Anyone else experiencing declining performance as uptime grows?
Mine is up for over 154 hours and SD performance has gone to hell.
This is noticeable with music beginning to stutter and Dungeon Defenders (a very demanding game) becoming unplayable. General web browsing also feels less responsive.
I've just rebooted the device and it's fine.
I'm now using MCR Fr17, but I've experienced the same on stock V10D. I wonder if the 0622 update is any better in this regard?
I have never experienced this. What sd-card do you have? I have a class-10 card and it works perfect. And also I don't see how the baseband would change anything for the sd-card but that could be beyond my knowledge. Music stuttering have previously been common in CM7 but is gone in later builds but then it was from start, not after 154 hours of running.
I am referring to the internal SD which is where I store my music and pretty much everything else. I only have a 1GB external SD for flashing ROMs.
Anyway I went ahead and updated to Fr19. Fingers crossed this won't happen again.
I don't think it's the sdcard performance degrading. It may be that your system is not efficiently cleaning up RAM. Thus you're having alot of apps that you've already closed still sitting in live memory. You can use various process managers to check it. (My personal fave is osmonitor.)

Concerning MIUI and a 32gb SDCard

Hi all,
Here's a odd little issue I was wondering whether anyone else was experiencing. I'm running MIUI 1.12.30 and I recently bought a new Micro SDCard for my IncS. Thing is, since installing the SDCard, the phone has been slow to wake from standby - you press the power button to switch the screen on and it takes a few seconds (sometimes up to ten) for the phone to return to its normal responsiveness. Until that point, the phone lags noticeably. This can vary, sometimes you can leave the phone for 1/2 hour and it's fine, other times you leave it for a few minutes and it's laggy.
Anyone else have this issue?

I had no problems with the ROM prior to installing the new SDCard, and I've been using it for a while now.
What class sd card is it? If it has a low read write speed that would be your culprit as certain apps installed to sd card might be lagging you out.

Class 4. Not sure how fast that is, really...?
Out of curiosity why would installing an app to the SDCard cause the phone to lag when unlocked? Wouldn't it lag all the time, or is that not how it works?
Well class 4 and 6 have a read write at about 4mbs while the class 10 that came with your phone is running at approx 10mbs. Roms use system folders undr the android directory on your sd card to log information and most of your google apps are located there as well. I'm not exactly sure all that is stored on your sd card all I know is it effects Rom speed.

I don't have it to hand to check, but I'm pretty sure that the sdcard that came with my phone was a class four or six. I'm pretty certain it wasn't a class 10.

I have miui 1.12.30 and 32g class 4 sandisk card, with no problem. It sounds like your SD card is not working as fast/stable as it should be. What brand is your card and where you bought it? It may not be a genuine class 4 I guess.
By the way, regarding class 10 SD card, I would not recommend it cos most of the class 10 card is built based on the sacrifice of random read/write speed to achieve fasting large file access rate. In other words, while you may find copying music, photos to/from SD card becomes faster, but loading game will be much slower which determined by random read/write speed.

It's a SanDisk, I brought it from Amazon Marketplace. To be honest, a dodgy SDCard was going through my head to. Damn.
I've head that about Class 10 cards, actually. Was probably going to stick with the Class 4.

Yeah I dunno dude thought mine was but I could be wrong, I can guarantee you anything higher than a 4 will perform better than a 4.
If your really concerned weather or not its your SD card you could duplicate them and see what happens with each.
Read this thread http://forum.xda-developers.com/showthread.php?t=1150369
You might change your mind. Basically depends on what you store on your card you might need to choose lower class card. Bigger does not always mean better.
I can't comment on amazon, but I had a lot of trouble with counterfeit 32gb microsd cards off ebay.
The cards would appear the right brand and speed, and would be formatted to appear as 32gb, even though the actual size would be far less (512mb etc). Cards would "work" as expected, until you start writing data to the part that doesn't exist.
Try formatting the card and/or speed testing it on a pc to know for sure.

as said, just make sure none of the apps that you run in the background are on SD card, maybe youve moved your lockscreen or home app to SD card by mistake if you arent using the stock MIUI one?
i never put anything on SD card that i use on a regular basis or want access to quickly
Well, incase anyone is remotely interested I bought another SDCard from Amazon, but this time from Amazon.co.uk, rather than from a seller. Not only does it look more legit, but the issue with the lag upon wake seems to have gone.
Looks like the issue was the SDCard being a dodgey one.
