[Galaxy Tab 8.9 General] jeremy89632:
I think we have to contact the dev of touchscreentune and get him on board of this since both devices is kinda similar.
[Galaxy Tab 8.9 General] pseudoheld:
i sent him a mail. here are the responses:

looks like we are unlucky :(
[Galaxy Tab 8.9 General] pseudoheld:
being very upset with this problem i started poking around the build.prop

it might be placebo but i feel that when this is added:

windowsmgr.max_events_per_sec=300

it gets a little more responsive. still not what i want it to be but better than before.
[Galaxy Tab 8.9 General] the_hatrix:
Try Touchscreen booster

It seems to have helped mine.
[Galaxy Tab 8.9 General] pseudoheld:
thanks. seems a little more responsive.

here is the apk if anybody else was wondering:

[Galaxy Tab 8.9 General] modestone:
My 8.9 LTE is super sensative, probbly the most I have seen on any android tab.

I can just barely graze my screen with rhe back of my fingernail and it even picks that up.

Compared to my roomates ASUS Transformer Prime, wo cant even use his fingernail unless he really jams it down.
[Galaxy Tab 8.9 General] pseudoheld:
iinteresting but im on the tegra version which aparently has completely different hardware :(
[Galaxy Tab 8.9 General] MatteAce:
hi everybody

I'd like to try to find some answer to the annoying problem of the touch filtering.

I've been searching around the internet for days, I've also asked the author of TST but with no luck till now.

Is there anybody that knows or can address me to how this problem can be solved? I don't think it's just a hardware problem, but a software one.

I'm also willingly to write to Samsung directly, so wish me good luck.

If I'm not gonna find a way to do this in a couple of weeks, I'm quite sure I'm gonna sell this beautiful black useless brick to an iPad.
[Galaxy Tab 8.9 General] the_hatrix:
Try TouchScreen Booster?
[Galaxy Tab 8.9 General] MatteAce:
that's been the first thing I did, but the improvements it brings are very light.
[Galaxy Tab 8.9 General] DBBGBA:
Does the tablet really have different hardware between the wifi and the LTE version? (at least regarding the screen digitizer)
[Galaxy Tab 8.9 General] trekker99:
Hmm, is it really a sensitivity issue? If I swipe first then wiggle like you mention, the screen will wiggle slightly. It sounds like there is a threshold to switch from holding the finger down motionless, to scrolling from left to right.

Perhaps a threshold setting (if available) is sufficient to overcome this?
[Galaxy Tab 8.9 General] Kasracer:
I'm noticing the samething. When I first saw this thread I thought everyone was crazy but after trying to type large amounts of text I've found it incredibly unresponsive in landscape mode (though portrait feels perfect!). I'm eagerly waiting for the official ICS update as in hoping it'll fix some of these issues.

It would be nice if they at least updated us to 3.2.
[Galaxy Tab 8.9 General] MatteAce:
I have Samsung 3.2 OTA update and it really changes nothing.

Btw no answer yet from Samsung, and yes, the problem is just about some sort of accidental touch filter
[Samsung Galaxy Nexus] neillh:
Has anyone noticed low wifi signal.

I tested standing next to my wifi router with my:

old HTC Desire: 100% wifi signal

new Galaxy Nexus: 70% wifi signal.

Walking a few steps back the Nexus drops to 50%, Desire stays at 100%.

Anyone else?
[Samsung Galaxy Nexus] NZtechfreak:
Same here, worst signal I've ever hand in a mobile for WiFi. Only really a problem when I'm quite far from the router with walls in between, still though, none of my other handsets had this problem.
[Samsung Galaxy Nexus] MaxDNet:
Same here. Was just searching for some update here from xda guys i'm sure i saw something in the past days.
[Samsung Galaxy Nexus] cjeremy:
me too, wonder if this is just a GN thing or affecting just some of the phones..... sigh.
[Samsung Galaxy Nexus] aimetti:
i think overall this is the worst reception I have ever had on a cell phone. Its really the first one thats ever given me a problem in my house. Constantly drops to 1 / 0 bars which is like -107 to -111 dbm but i pop in simcard into my 4s and its at -87 dbm. Same type of thing with wifi as well.

I have tried other radios and it seems that UGKK7 radio works best for me on ATT.

Ive tested the UGKL1 for just an hour or so and this one may be the best yet for me. TO early to tell though. I can say that im on full bars for both wifi and hspa for the first time at home with my GN. Just curious if it will hold though. Usually it ends up dropping and not recovering.

But wifi tether doesn't work for me at all.

Please help me straighten it out if it can be and thanks in advanced.
[EVO 4G Q&A, Help & Troubleshooting] swagstr:
Try flashing a new kernel.

Don't work... wipe/re-flash.
[EVO 4G Q&A, Help & Troubleshooting] polar2792:
What all should I wipe when I flashed I wiped user/factory reset, system,boot, dalvik, and Android secure. Anything I shouldn't have wiped?
[EVO 4G Q&A, Help & Troubleshooting] swagstr:
You should be good, would be ideal to do each about 3 times.

So, I would just re-flash a kernel.

Oh, and (the built-in) WiFi tether does not work with 4G (or if it is not unlocked).

[T-Mobile LG G2x] mojorisin7178:
Hey guys I use an app called cpu master pro it is made by AnTuTu I actually use a few apps made by them and in the power saver app they advertise a program for root. At the bottom it just says root tool. It is new because I have been using it for a while since my g2x and so I checked it out. It is called "unlock root” You can find it at unlockroot.com. You can root and unroot with it on multiple devices all you need is the drivers for that phone and make sure you have usb debugging checked. It is obviously a computer app and it is truly a one click thing. Now I have tested it out on my g2x and can confirm that it will unroot and root it. I am running whitehawks weapon 3.0 ROM with dragon kernel overclocked to 1.5 ghz and when I hooked up my phone to the pc it found it right away and I hit unroot and it took all of 4 seconds then it rebooted the phone and it was done!! I tested it I was able to watch movies from the Google market on the phone and titanium did not receive root permissions. Then I tried to root it and did the same procedure expect I hit root this time and same results 4 seconds done!! This is different than superoneclick I think someone else told me it is just a clone but correct me if I am wrong but last I heard superoneclick does not work to root the g2x with gingerbread right?

I am going to test it with my SGS2 in a few minutes but it is listed as one of the devices that it works with. So far it looks like it works on 4 HTC phones 4 Samsung galaxy series phones and 4 LG phones. On closer look I notices that the SGS2 listed is the 9100 not any of the others but I also only lists the optimus 2x and the g2x worked so I am going to give it a try.

So try it out and let me know. And of course I am not in any way shape or form a dev and I am not responsible if this program makes your phone grow a brain and masterminds a plan and leads a robot army to take over the human race!!

[AT&T Samsung Galaxy S II SGH-I777] honghsien5:
My galaxy s2 would sometimes get disconnected from wifi.

When i check the wifi setting, it says that the network is disabled.

i have to wait a while before wifi is reconnected.

Wifi connection seems really unstable for me.

running un named 1.3.1 ICScrewed 1.11 and entropy 12/01 kernel
[AT&T Samsung Galaxy S II SGH-I777] Shammyh:
Actually have had similar problems. Sometimes one of my two access points at home acts up, and will bug out during the 4-way handshake (to initiate an WPA2 session). If that happens over and over a certain number of times, Android will "disable" the access point in the configuration list....
[AT&T Samsung Galaxy S II SGH-I777] honghsien5:
so is there a way to fix that?

since i'm living on the college campus , there's probably a lot of routers in my area. maybe this is why i kept on getting disconnected from the wifi
[HTC Desire S] DSoul:
can this rom use mobile data?

[General Questions and Answers] harwooc:
I am getting ready to put this rom onto my phone and before doing so just wanted to make sure I have the process right. I transferred the .zip file onto my microsd card and now i just simply boot my phone and it will open a menu where i can make a backup and then continue correcrt? i have not done anything to my phone to prep it for this and just wanted to make sure there wasn't any preemptive steps to take before beginning. Any help is greatly appreciated.

my main concern was just reading a lot about needing s-off and downgrading to 2.3.3 on devices before installing roms. i have not done either of these and wasn't sure if it was required for this particular one
[EVO 4G Q&A, Help & Troubleshooting] shinesthru:
When I browse my sd card, and try to open a specific folder using Root Explorer or the "Root Browser" tool in Rom Toolbox, the folder appears empty. However when I browse my sd card on my PC while connected to USB in disk mode, or with the Script Manager app, or while in recovery, the folder contains all the files I have placed there previously that I would expect to see. Permissions for the folder are set to "--xrwxr-x" just as all my other folders on the sd card are set to. I am rooted (obviously), running Deck's 1.3d with Tiamat 3.3.7, and using DarkTremors a2sd.

Any ideas why the files are not visible in certain apps?

You can always backup the contents, format the card, then move what you need back.

Alright everyone... future development for the Epic will start moving quickly, and I ask that everyone PLEASE watches this and pays attention to eliminate future questions. This video explains MTD. Please keep discussion going, as I'd like to see this on the first page for everyone.

[Epic 4G General] k0nane:
Thanks for this, users are going to be quite confused, and this will help a lot.

For those who might be a bit more interested in the differences:

BML and MTD's main difference is how they access the flash memory. Flash file systems, like YAFFS2, are designed to access the raw memory, without anything particularly fancy sitting in between, while block file systems, like RFS, EXT4, and others, operate on block-level storage devices. This is why your hard drives and SSDs use file systems like EXT4 - they have controllers that expose the block layer. The same applies to your OneNAND device in your Epic.

Samsung's OneNAND product in this device uses what they call XSR - "XSR is a layer between filesystems and NAND devices that uses logical sector relocation to prevent too many overwrites of the same block and to relocate bad blocks." There are two layers to that: "BML (Block Management Layer) are the devices on bottom of XSR exatly on top on NAND low level drivers.", and "STL (Sector Translation Layer) are the logical devices on top of XSR" (for data partitions). In using MTD, XSR is essentially eliminated completely. That's not to say the tech is gone, as Odining back to stock (as QB points out) is plenty possible, but it's no longer in use.

MTD stands for Memory Technology Device, and is "a new type of device file in Linux for interacting with flash memory". It "was created to provide an abstraction layer between the hardware-specific device drivers and higher-level applications". Its purpose is, was to put an end to the translation - flash memory devices like the OneNAND device in our Epics are not block-level devices, so why try to shoehorn them? In combination with the more 'direct', so to speak, access to the memory device that MTD provides, flash file systems like YAFFS2 handle all the optimization required for proper data handling. In a way, they combine the functions of something like Samsung's XSR and a traditional file system.

YAFFS "is a robust log-structured file system that holds data integrity as a high priority", and a "secondary YAFFS goal is high performance". I'm sure some of you will be wondering what read/write performance will look like after the transition - I am too. But that will come.

Don't be afraid of change, folks. :)

[Epic 4G General] xTmDarren:
Great video as always qbking77.. This actually gives me a reason to hold off a little longer on getting a new device..
[Epic 4G General] ddrbeastappv1:
this is incredibly good news so the question is if its possible to run cwm and change the file system like how we already do between rfs and ext4 but now to yaff s? qb king mentioned odin but I would assume it what I mentioned could be possible.
[Epic 4G General] o0oXDAo0o:
I'm sure the awesome devs we have will figure out a way, hell I'd like to contribute if I get some time as well. We might have to start with odin, but we are already able to change file structure by simply flashing a rom. Definitely going to have to do some research.:)
[Epic 4G General] AproSamurai:
Semi Nerd Rage! Lol not really :) (Told you gameboyking24)

Guys, the conversion from RFS to EXT4(vice versa) is not the same way you'd go about getting to YAFFS2. Take it as this way, BML is a race track where only rfs and ext4 can race(in theory) while MTD is a track umpteen miles away where yaffs2 resides racing alone(in theory). BML and MTD both the same as they serve the same purpose but handle it in a different means. They are exactly what they've been explained as but in simpler terms they are partition maps. Not a filesystem. Our filesystems reside on the mapping of a BML or MTD as of recent partition map which allows us to customly resize partitions where we see fit. If and when you decide to make the move to MTD all things BML are restricted to you until you odin and repartition back to BML. So it's at the moment not the matter of a dev making an RFS to YAFFS2 zip, unfortunately there is a lot more involved and put into this whole process.

[Epic 4G General] ddrbeastappv1:
Thank you Apro. I understand a little better now but I am unfortunately fearful of Odin since i've swapped at least 7 epics at the sprint store because I either fail at the odin process or fail at installing drivers ><
[Epic 4G General] AproSamurai:
Oh it's no problem at all man. :) I would for the meantime stay away from MTD for a bit until there is a lot more going on, so you've a stable failsafe rom over on that format.
[Epic 4G General] noobnl:
It gets 2100 in quadrant.
[Epic 4G General] counterfeit187:
So when the roms that work on MTD tables come out, will we first have to use Odin to repartition/ flash the roms in odin as opposed to clockwork. I saw mentioned that it would be possible to flash back to stock in odin to get BML back. My question more simply phrased, how will we convert from BML to MTD?
[Epic 4G General] noobnl:
flash using an update.zip
[Epic 4G General] ÜBER™:
And I thought odining back to stock was hard enough XD

Looks like I chose the right phone was very tempted to get the evo ^^

[Epic 4G General] Mushmaster:
I like the part at the beginning where you touch your phone obsessively.
[Epic 4G General] KennyG123:
Does a ROM have to support MTD and is it only in the kernel for that? Will the ROM be able to be used on either BML or MTD at that point?
[Epic 4G General] Neckberg:
This is some really exciting stuff. I am planning on keeping the epic until the new LTE phone roll out, and this has given me some hope for ICS and CM9.

Thanks to all the devs that put in some serious time on this.
[Epic 4G General] AproSamurai:
As far as I know not necessarily. However it's likely there will be Roms which are more catered for MTD in the separation of sizes. So if it requires more space in /System for essentials to run, it'll likely be an MTD only thing. But if the size of the System partition isn't needed to change then you can run it on either of the two ,as long as the kernel you're using on BML has what the rom needs to properly boot. If that makes sense?

I was going back and forth a bit lol.
[Epic 4G General] Specialksg1:
So current ROMs would likely work on MTD with the right kernel, but ROMs designed on MTD might not work on BML?
[Epic 4G General] xboxfanj:
Kind of. For MTD, ROMs need more than just a new kernel: they need a different updater-script and other mtd scripts (like updater.sh and blm_over_mtd.sh). For example, on my MIUI builds, I port from NS4G and Fascinate which use MTD, but if I delete the MTD files and add our kernel and updater-script, it is now bml. Also, most MTD ROMs will work on BML except for ICS or anything that has too big of a /system folder. And with the right modifications, any BML ROM can work on MTD. Hopefully that answers your questions and other peoples'.
[Epic 4G General] Specialksg1:
That clears everything up ... leave it to you guys ;) lol Exciting times, good luck and god speed!

Welcome to the Epic forums! (Even if you've been lurking for a while. ;) ) It can be a rowdy place with dumb questions being asked, flamers flaming, tempers flaring, and trolls attempting to snatch unsuspecting Topics, but you can learn a hell of a lot about the Epic and phone/Android hacking in general.

Back on topic: thanks a lot to everyone who provided info about MTD and YAFFS2, I think I thanked all of you!
[Epic 4G General] flastnoles11:
This is very promising news for all epic owners. Everyone who knows someone with an epic should direct them to this video/thread as it will make conversion much easier for everybody in the (hopefully) near future!
[Epic 4G General] 49ml:
Wow, thanks for another great video, cant wait to see what they plan to do.
[Epic 4G General] KennyG123:
That was informative but what about the actual procedure for putting MTD on the phone? How difficult will it be? Just Odin with a partition map? Will there have to be a new CWM to work with it? Qb, you said it was on your phone already running CM7. This was more like a movie trailer...lol.
[Epic 4G General] xboxfanj:
Flash the cm7 zip and it does it for you. Same goes for the new miui zips too. But to get back to bml, you must odin.
[Epic 4G General] KennyG123:
Ah, that must have been the ??? step...lol. Thanks. So we can expect some future ROMs to also do the reformat for us. So is there a working backup on BML and restore on MTD yet? I thought CWM 5.0.2.7 is not MTD ready.
[Epic 4G General] xboxfanj:
The roms with it included (miui.us and cm7) flash a new cwm recovery that is compatible with mtd
[Epic 4G General] KennyG123:
Ah, does it preserve data between conversion? Or is it only for flashing between MTD ROMs? I see a lot of users asking the ROM makers to make an MTD version. Is it an easily doable thing?
[Epic 4G General] xboxfanj:
No it doesn't. U can't restore previous cwm backups either. Backup using titanium. Idk how easy it is for the mtd thing, since I just copy the cm7 mtd stuff to miui.us and it works. Its definitely possible and we will see it soon.
[Epic 4G General] KennyG123:
Thank you so much for answering all of these questions. I am trying to get an idea as to how far away this is for EI22 ROMs.
[Epic 4G General] MДЯCЦSДИT:
You can't have mtd on tw roms. They don't have stage 2. It boots but then rebooted after a little bit (short bit).
[Epic 4G General] KennyG123:
So users should stop asking for MTD versions?

I have been an android user and still am

But I feel the HD7 is not the best of phones now if you really want to try wp7. I would have suggested the Titan or Nokia Lumia.

not that specs matter with regards to wp7 but I am sure you would have loved the extra battery power.

Hd7 dosent last much long... and I love the android customisations, but keep coming back to wp7 now and then.

I feel wp7 will be the best with Appolo. Mango has done a good job but its still not upto the level, also by next year with the release of appollo, wp7 market would have caught up a bit as well.
