run your quadrant test, i got 1793. enjoy.

ps: if you want make it permanent look at RyanZA playlogos1 trick. Also make sure your ext4 filesystem is available at boot time instead /sdcard/sddata

Note:

- due its nature ext4 keep data in RAM much more than ext3 before writing on disk, therefore if a powerloss happens before data got written this may results in lost of data. (see delayed allocation). On the other hand a temporary file wont be written to disk, but kept on RAM avoiding read/write cycles. Inode reservation can increase performance as well.

- barrier can be disabled but this may result in a corrupt journal
[Galaxy S I9000 Android Development] dark_sith:
explain please
[Galaxy S I9000 Android Development] husq510:
you may want to use ext4 without reflash, and at the same time keep your /data untouchable, just in case you need a recovery backup. eg: if /sdcard got corrupt, system will mount your original /data. (desynced)

I had to disable vold, and mv /etc/vold.conf /etc/vold.old, otherwise it coundnt find /sdcard/filesystem.ext4 so I mount it just before everything.

Do not forget to create /system/bin/playlogos1 as follow:

I got 1858

this is just proof do not use on your device if you dont know what you doing. Since vold does not mount partition some application may not recognize /sdcard mounted that way.

id like to find a way to start vold before playlogos1 and resolve this issue, buts vold seems check argv[0] before start.
[Galaxy S I9000 Android Development] Chainfire:
e2fsprogs recompiled as well ? In other words, will the e2fsprogs from cynogen work on ext4? These do use libs, btw.

I might build support for this into CFLagFix if I can freely use the files :)
[Galaxy S I9000 Android Development] husq510:
yeah static bin.
[Galaxy S I9000 Android Development] Tayutama:
Just want to ask if it's ok to implament this in my lagfix zips :)

Ofc ill credit you :)
[Galaxy S I9000 Android Development] husq510:
sure you can.
[Galaxy S I9000 Android Development] bub181:
Thanks for the statically linked e2fsck :)
[Galaxy S I9000 Android Development] Tayutama:
Nvm got it working on captivate also

i install this in my fresh htc hd2

but nth show out , and i go setting - today , i didnt found anything.

can somebody teach me how to let it works,its a cab files i already install it.
[HD2 General] khabat1:
I have same problem. my phone is experia x1 with wm6.5

I want to put some movies on my SDHC and the internal, but I can't copy files over larger than 4gb. Is there a workaround?
[Captivate Q&A, Help & Troubleshooting] max_warheads:
Convert your files to something more appropriate for a portable.

480p screeen resolution, so no need for 720+

http://Handbrake.fr
[Captivate Q&A, Help & Troubleshooting] asrrin29:
It's a limitation of the filesystem the SD card uses, fat32. You'd have to format the sd card to use a different filesystem AND flash the kernal so that it can read said filesystem.
[Captivate Q&A, Help & Troubleshooting] muthaflaco:
I know, but since I had them already encoded, and sitting on my hard drive, I'd just throw them on there. I'm all for a kernel that will read NTFS formatted volumes. Thanks for the replies.
[Captivate Q&A, Help & Troubleshooting] bwolmarans:
Why would you have bluray size movies on a hard drive when they won't look any better (because you're not playing them on a bluray player)
[Captivate Q&A, Help & Troubleshooting] asrrin29:
NTFS is not one of the current possibilities, plus even a desktop version of linux has compatability issues with it. I don't know file size restrictions, but current kernels you can flash will support ext2,3, and 4. I think someone is also trying to build a kernel for yaffs.
[Captivate Q&A, Help & Troubleshooting] muthaflaco:
I backed up all my Blu-Ray's to .mkv files in 720p. That way I can have them on my HTPC that's in the living room. Also, my kids have dirty little hands, and I don't want them ruining my originals. My desktop PC gets regular movie use too. 24" 1080p ASUS monitor. :))
[Captivate Q&A, Help & Troubleshooting] truelies1:
Galaxy Note also has this problem. How can I copy a video more than 4G. Note support 720p.
[Captivate Q&A, Help & Troubleshooting] xhozt:
EXfat would be a godsend if some one wrote a kernal supporting it ..
[Captivate Q&A, Help & Troubleshooting] Sword_of_a_1000_truths:
u guys can always split the files in smaller parts, i use mkvtoolnix(freeware) to split mkv files into multiple parts while leaving the original untouched and doesnt take a whole lotta time depending on file size
[EVO 4G General] Jsimon9633:
I bought my evo on July 31st, This means I get til August 29th to decide to return it or not.

I am considering the Epic 4g but with so much Dev love for the Evo. I am having a hard time really committing to the switch.

I am currently running cyanogen nightly and its pretty damn awesome, getting great performance both synthetic (quadrant 1500+, fps2d 53 frames, 31 neocore, 38 linpack)

Is anyone having the same dilemma? I like the allure of the better processor/graphics on the Epic. I dont care about the physical keyboard. The Amoled screen is somewhat tempting except for the pentile matrix display and the fact that its smaller.

The real stopping points for me are:

1. will it receive anywhere near the support from devs as the evo?

2. The performance both real life and synthetic that I get on the Evo seems to outpace any stock version the Epic could see.

3. Gaming is probably better but in reality android platform doesnt have many games and I have an ipad to play those anyway.

Just trying to gauge current Evo owners thoughts on this.
[EVO 4G General] mcbrided:
Not a chance.

I like my 4.3" screen and can input faster with Swype than I ever could with a physical keyboard.

Feels like a downgrade to me. I will replace my Evo as soon as I have no question as to whether it would actually be an upgrade.
[EVO 4G General] sling:
Na Epics not in my future.
[EVO 4G General] Aridon:
I'll probably be picking one up. The hacking community should be just fine its being released on just about every carrier world wide and once the keyboard parts ate isolated it will be trivial to support.
[EVO 4G General] TheBiles:
I was interested in it originally for the Super AMOLED and Hummingbird, but the phone itself is just ugly as hell, and I will probably never use the keyboard.
[EVO 4G General] h3nG:
I wish it didn't have a keyboard.

But it has a few neat features that appeals me:

Screen Size: The 4" screen seems like the "perfect" size for me.

CPU: Hummingbird process supposedly the fastest thing out right now.

Battery: Early reviews I've read indicates its last 50-100% longer than the EVO.

Two things about the EVO I prefer is:

No physical keyboard - therefore 1mm smaller.

Better front facing camera.

Better DEV support.

I'll probably stick with the EVO since it's a bit of a hassle to sell it and buy the Epic. Tempting though. Playing the sit and watch for now.
[EVO 4G General] engagedtosmile:
I love my Evo but if I was given the option to get an Epic instead, I would have a very hard time staying true to the Evo.

Either way, I am happy with the Evo for 1-2 years until the next big Android phone drops.
[EVO 4G General] Jsimon9633:
Mmmmm I can return my evo and get the epic so def. Makes me tempted.

If the Dev support was going to be near what it is for the evo and it had no kb I'd probably 100% get it
[EVO 4G General] dglowe343:
Nope. IMO nobody has made a better Android phone than HTC yet. Android development started with HTC phones. Plus, I hate physical keyboards.
[EVO 4G General] Joshonekenobi:
Hands down the Evo is better....... regardless of the Hummingbird Vs Snapdragon.

Stuck on Stock HTC 2.2
[EVO 4G General] rockethot:
I have an evo and it's given me so many issues that I think I'll probably switch to the Epic. The only thing holding me back is that Sprint gave me the Evo for only $100 and I'm not sure if I want to spend an extra $150 for the Epic.
[EVO 4G General] ekokinex:
OP I've been going through the same decision process. I got my Evo on July 25th, and of course they release the date for the Epic. I've reserved one but I'm not sure if I'll return my Evo for the Epic. The battery issues, FPS cap and lack 802.11n on the stock Evo w/ Froyo (2.2) is what makes the Epic so much more intriguing. Also it has that Super AMOLED display and Hummingbird CPU. Its a tough choice.
[EVO 4G General] Andy S:
I thought one of the first updates after release turned on n support? (still waiting for my phone, so can't test myself)
[EVO 4G General] ekokinex:
That was the rumor, but it would seem the only way to enable it requires the user to change some code on the phone itself.
[EVO 4G General] nicholaaaas:
the better processor is the only thing that might tempt me... but i still have my upgrade and think i'll wait till gingerbread is closer and something miles above either is out
[EVO 4G General] Maxy6:
A big question is whether it will have GPS, or at least a working GPS.
[EVO 4G General] ritzbrie:
The grass is always greener. You know what you have, you don't know what you'd get.
[EVO 4G General] SouthernEvo:
I have to agree with this statment . In relative terms the EVO is still fairly new to the market . Granted its been out for two months but overall that isnt very long (But I have been known to get dates screwed up LOL) . This phone looks ok but the keyboard is not something I would jump all over . Also battery life for this thing would be another thing I would be cautious of . Yeah the evo isnt record breaking for its battery life (this seems to vary from one owner to the next) but whos to say the epic isnt gonna be any better off . Just from my own standpoint I know how I am with phones with moving parts I tend to break them and people look at me going "how the hell did you do that?" LOL I honestly dont know . So I usually stick with the single piece phones . My advice would be to let others jump on that boat first and before long you will hear of what downfalls it might have THEN jump if you still want to at that point . Its nice to have the coolest baddest thing out at the moment but sometimes if it doesnt work worth a damn it isnt worth it .
[EVO 4G General] LordLugard:
Before the Evo came out we were all salivating at the raw specs and bla bla and when it was released and we all became privy to its faults we all calmed down. I'm in the not pleased camp on the Evo, just too many issues to deal with.

My take is to reserve judgement on the Epic until it is out for us all to play with and handle before dissing or going all out with praises on it. On paper, it blows out everything and their grandma but I've been had before.
[EVO 4G General] sfox8:
Every new phone is going to blow everything out of the water on paper. That's the whole point of leaks and media hype.

If you're always trying to wait for the "next best device" then you are NEVER going to get a new phone because trust me: Once the Epic is released, there will be a new phone leaked that "blows all the Galaxy S phones out of the water". Then once that phone is released, we'll repeat the process.

There is never going to be a perfect device and the Epic/Galaxy S phones are no exception. They have some better specs but what are the trade-offs? By being early adopters (most of us) for the EVO, we took the risk of not knowing the faults and we are either accepting those faults and enjoying the device for what it is, or we're jumping on the "next best thing". Personally, I'm sticking with the EVO. For all its faults, there has never been anything that has frustrated me enough to say it's a crappy phone or want to return it. The EVO is the best device I've ever owned hands down, no competition. The Epic looks really nice but I can do without.

There are doubts that I have about the Epic even before it's released that are making my decision to keep my EVO even easier.

1. Samsung has yet to prove to me that they can be trusted with support and updates. Yeah, we keep hearing the excuse that its on every network but as I said, I haven't seen any proof yet so once Sammy can PROVE to me that they've changed their non-supportive ways, I won't be investing any money on a phone from them.

2. Community/Developer support. With 3 out of 5 Galaxy S phones released (Vibrant, Captivate, EU Galaxy S), I still haven't seen the same amount of developer support for the Galaxy S line as I have for the Evo itself. Customization is important to me. Also, when I have a problem, I like to know that there is a large community of people I can ask that increase my chances of getting it solved asap. Again, this is something that only time will be able to tell.

TLDR: Despite its minor faults, I'm more satisfied with my Evo than I have ever been with any phone I've ever owned. The Epic looks like a GREAT device, but there is nothing about it that makes it good enough to switch for me. If the Galaxy S line goes well, then I may buy the next generation of Galaxy S phone, but as for right now, no.

That won't stop me from geeking out over any of my friends who get one though! SuperAMOLED is beautiful!
[EVO 4G General] scl23enn4m3:
I'm happy to say I got lucky enough to avoid any problems with my Evo. (Except my battery door not fitting properly. But I've been lazy in trying to get a new cover, since it doesn't bother me much.) But there is no way I'd be able to use a phone with a smaller screen. 4.3" has set the bar for me.
[EVO 4G General] TheBiles:
Try folding a sticky note in half 3 times and placing it between your battery and the battery cover. It did the trick for me.
[EVO 4G General] mmegalodon:
Never been a fan of Samsung devices, but it does look like a more than decent offering. I don't game though, not watching movies a lot and when I do they look fine on my Evo. For me it would come down to the keyboard, something I was nervous leaving for a touchscreen only device but I don't see myself ever going back.
[EVO 4G General] dmora01:
I remember when the I had the hero and the samsung moment was realesed with faster procesor and amoled screen, I returned the hero for the moment, worst mistake, no agps working and used to take 3 minutes to lock position, no way, bad bad battery and likes to reboot all the time. My wife still using the moment and with the 2.1 update still so so. I never going back to samsung.
[EVO 4G General] Success100:
The only thing that entices me about the epic is the super amoled display.

the hummingbird core looks better on paper, but the reviews on it have shown that it exhibits a lot of choppiness during scrolling and pinching/zooming in and out of things. The EVO to me is an almost perfect device, I mean sure it has flaws (my major one is the fps thing, I shouldn't have to get a custom Rom to have a clean scrolling experience, even tho I've always ran custom roms, and even still, there limited to about 53-55 fps), and the crappy video encoding. Other than that I would sell my truck before giving this thing up. I work in a corporate sprint store and I'm anxiously waiting for the epic seed device to come in. I saw a lady who had an at&t galaxy phone, and I got to see the screen up close, and I was blown away by it, so I think its gonna be a tough one for me, but ultimately, I think ill be sticking with the EVO...

Sent from my Damn EVO!!
[EVO 4G General] goodelyfe:
lol if it isnt broke, why fix it?

all this hummingbird and super amoled screen talk is hogwash

i have to agree with the rest that infact the evo is almost a damn near perfect phone/device (sure has a few kinks, but what doesnt). one of the (few) king of the androids imo

however i wont front, that display may be a tad bit just a tad nicer however that .3" of a loss is very noticeable.. you wouldnt think so, but it is
[EVO 4G General] Jsimon9633:
Well the epic reviews are out from gizmodo and engadget

Giz claims it's much better than evo but for some reasons that don't apply if you have a rooted evo

Engadget has it a near tie but gives the nod to evo unless you really want a hw keyboard.

Looks like evo is staying in my pocket

Especially with the latest rims/kernels I've been using giving me great performance and battery life
[EVO 4G General] Last-Chance:
I will never buy another samsung phone in the future. Had the samsung instinct, aka the iphone killer. took them ~5-6months to add keyboards to java apps. And a lot longer to update issues with the browser.

They are horrible when it comes to supporting their phones. After the java update and the browser update, they haven't fixed nor updated any other problems with the phone.
[EVO 4G General] 063_XOBX:
I played around with a friend's captivate (just another one of the Galaxy S phones) and found it to be extremely choppy when it came to scrolling which was a surprise since the Hummingbird processor is touted as the best
[EVO 4G General] goodelyfe:
those where my same thoughts

and lmao @ the iphone killer, i guess you too remember how much they hyped it up and to miserably fail on its face...lol
[EVO 4G General] bharris25:
Samsung has a questionable past of updating from what I've heard. If not for the gaming or hardware keyboard I don't really see any reason to switch, I have an anti glare screen protector on my Evo from sprint and have no problems seeing it just fine in daylight, battery life is just fine for me too. I was thinking about switching but I like my Evo just fine.
[EVO 4G General] LCfromNY:
I will NEVER EVER EVER purchase a samsung phone again! I was a part of that instinct debacle! iPhone killer.. HA! My next phone was the Hero, my gf purchased the Moment, and hands down (IMO) the Hero was a MUCH better phone. We both have EVOs now and neither are interested in the EPIC.
[EVO 4G General] luiggipr:
I agree, I remember when I bought the instinct and promises of upgrades were many and none came
[EVO 4G General] Itchiee:
It would be more tempting if it didn't have a keyboard.

Enough with the thick ass phones....

I'm still sitting on my upgrade and will see what comes out next year.
[EVO 4G General] racemepls:
After having to try to fix 2 moments today with the "airplane mode issue", 1 instinct with no screen sensitivity, and two intercepts that were droping calls left and right it just reminds me how bad Samsung is at making pda's. This is every day I have customers bringing me their Samsung phones with the same problems that never have a fix. It's a huge headach for the customer, Sprint, and myself. I would strongly suggest reconsidering getting one.

HTC does have their issues as well but usually they are easy fixes except hardware problems aren't too common.
[EVO 4G General] Success100:
i played with our demo epic all day today, and honestly, im not that impressed. It is a VERY nice screen, but as stated all over, colors look highly over saturated, and text is grainy because of it. I am envious of the 60fps when scrolling through menus, but thats ALL. Touchwiz is a JOKE. The capacitive android buttons work when they want to, cameras are much lower quality, and the screen is smaller. MY unbiased opinion? I think the epic is better for the GENERAL public out of the box vs the evo. That being said, For us XDA people, The evo is still the clear winner. Ill take my over clocked custom rom'd up ass evo ANYDAY over the epic. GO HTC!
[EVO 4G General] davebu:
HTC makes much higher quality products than anyone first off. the hummingbird is supposed to be better, but since the galaxy s are all on 2.1 we cant really see their full potential yet. also, all the galaxy s phones are having major issues with gps/network location fyi, should be fixed by the froyo update though, it is software only. im going to be carrying both when we stock them at clear, since i have an evo now and i dont wanna carry 2 evos, but i think the evo is the better choice. the sdx devs will have some decent support for it though. they had an amazing online rom/kernel kitchen for the moment.
[EVO 4G General] ConceptVBS:
Its only a matter of time before the source code is released from Samsung. Both the Captivate and Vibrant's source code was released by Samsung as soon as it was launched.

With the considerable development done on the Vibrant and Captivate, and seeing how similar these phones are to each other, there are already bits and pieces being ported from Epic to Vibrant/Captivate and vice versa. The files from the Epic 4G has already been dumped and it looks like there are only minor differences.

Internationally, the Galaxy S is already well developed. A Ubuntu port is in the works.
[EVO 4G General] EtherealRemnant:
Honestly, I think the Galaxy S line is going to set the bar for Android devices considering that Samsung will have just about every carrier in the world with a variant (even US Cellular is getting a variant) and they all have pretty similar hardware (other than Sprint's stupid decision with the Epic's internal storage - HUGE WTF move Sprint...) I imagine that devs will develop for the devices that end up with the most penetration - obviously the Galaxy S is going to wind up with the most penetration - and the Adreno can't even come close to the SGX 540...

It will be interesting to see what happens with Qualcomm releasing 1.2 and 1.5GHz dualcores this year.
[EVO 4G General] fallendusk:
If it was a HTC phone, then I would of considered it. I just don't trust Samsung.

As much as I love my EVO, I really wish I had a hardware keyboard for using ssh. Not that I really have any choice since its been past 30 days, and I can't afford the retail price.
[EVO 4G General] EtherealRemnant:
I think its hilarious how many people seem to forget about HTC's blunders over the years...
[EVO 4G General] Beejis:
Well said!
