Great

Thanks for posting your methode

But u dont need to use another swap apps to activate linuxswap part. U just need a2sd to run it.

Maybe use sparated post for swapper to post 2nd or third as alternatif

But thanks anyway

Just Kick Thanks Button...

@All

This Thread are Specially Made for S6102 Stock ROM Users who want to Activate A2SD, Link2Sd and Swap Function etc

but Sorry for Stock Kernel User it Wont Run Properly

You Must be Know that u can Install and Run easily in Custom ROMs

But not for Stock ROMs...

Just Follow the Usefull Guide that already Write by sgyd12

atleast its work on me...

Thanks
[Galaxy Y Duos S6102 Android Development] sgyd12:
Ya.. that right..

But... With Swapper we can add more of RAM and easy to change it..
[Galaxy Y Duos S6102 Android Development] MNgez:
Yup you were right

swapper is only for someone who were not already has any swap partition on sd card.

if u have already third partition as linuxswap you just need to activate it in a2sd using a2sdgui.

it's work on me well.

sorry cannot send any ss

i'm in slow net now.

alsi if u using some fat part for swapper... when u test in benchmark it will slowing down on read and write sdcard.
[Galaxy Y Duos S6102 Android Development] Tanrulz:
Noob

Can you explain the first step??How to make 3 partitions on SD Card??:confused::confused:
[Galaxy Y Duos S6102 Android Development] sgyd12:
U can use MiniTool Partition Wizard.. Or from CWM
[Galaxy Y Duos S6102 Android Development] kaorukail:
You can also link manually via root explorer with my guide :)

Anyway nice guide! Thanks :D
[Galaxy Y Duos S6102 Android Development] sgyd12:
Ya.. I'll Try ur guide..

Thanks.. :)
[Galaxy Y Duos S6102 Android Development] sgyd12:
Thanks for ur suggestion..

U will get the effect when playing games.. :eek:

*Sorry for my bad English bro.. :o
[Galaxy Y Duos S6102 Android Development] MNgez:
This is just like what i've told u before in your guide tread. But i am using a2sd only for app2sd, zipalign, also swap function. Data2sd and cache2sd i do it manually, to make sure i dont link wrong apps file. Thanks anyway both of you really help us.

Yup i know it... but i'm in good just only using swap by a2sd swap function. I'm also can play HD games with lag free. So i don't need swapper anymore since u get swap part activated by a2sd.

Anyway keep on rock...

May god bles u

[Galaxy Y Duos S6102 Android Development] Deadly:
You need to create second partition first.. use any partition managers like paragon partition manager.. or easus partition manager.. or minitool all windows softwates... or use cwm-->advanced.. but I have not tried cwm option.. remember keep backup of sdcard in system before doing above task... create 100 MB at Max.. more than that not needed...

Hi i did an update on the Google maps app a couple days ago and today I noticed that it has been draining quite a bit of battery. Does anybody know something that can fix this issue or do I just have to wait for an update?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
Turn off the GPS and exit maps....
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] xChris76:
Well it never happened before the update and it drains the battery when my phone is in sleep. Also the maps app is not opened.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
Just because it isn't currently on your screen doesn't mean it isn't open... It could still be holding a lock... About all you can do is turn off the GPS, and clear its data.... Either use TiBu to clear it's data, or press and hold the maps icon in your app drawer and drag it up to app info, hit clear data and clear cache... and only turn on the GPS if you're using it...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] xChris76:
Ok but is there a way to downgrade the version to the previous one?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
There's always a way... But it's not as simple as going to the play store and requesting an older version.... If you have the .apk you can replace the current one with an old one, or if you have an nandroid with an old one, you can unzip the nandroid, go to system/apps and get the maps.apk or just flash to an older backup and not update maps...

but that's not going to ultimately fix your issue... i really think it's just holding a lock all the time and it's the gps... which is why i suggessted turning off your gps, and clearing maps data... and if you keep gps on all the time that's pointless, unless you're navigating because apps can get your location pretty accurately based on the towers...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] xChris76:
The thing is I've had gps and everything on before the update and it's been getting great battery life. It's only happened since this update. But I will try having the gps off and let you know how it goes.

Thanks
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
Which is why I suggested turning off the GPS and clearing maps data... after that, turn it back on if you want, it's the only way to know if it fixes it... just have it off when you clear the data... any issue with a specific app, that's what you do first, clear all that data's memory of anything...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] TRusselo:
the latest maps update was soft rebooting my dads sensation...

but i know enough from using maps, that if it isnt on your screen (still in background) it DOES drop gps signal, and shouldnt be eating up battery in background.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] equlizer:
Try "Autostarts" or something similar and disable maps at startup.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dLo GSR:
none of these solutions addresses the problem. the update has something that is keeping the phone awake and consuming battery. if I start my phone from OFF and let it sit for an hour, I can look at my battery stats and 10% of it will have been consumed by google maps, without me having ever opened it and without a single GPS query.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
Then contact Google about the issue...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] artisticcheese:
Probably Google latitude
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Nitroturtle:
Try turning off location services also. I was having issues with my phone properly sleeping and that turned out to be the cause.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mikeruoc:
The location services was part of my issue. Lowered the batt usage a lot but maps still shows up as a large user of batt.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] drock212:
I went to the apps info and uninstalled the update simple as that.

Edit: TiBu can also uninstall updates
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tripintaz:
The latest Google Maps is doing the same thing to my phone. I have always had GPS and location services enabled and it never ate up battery like the new Google Maps version. Turning off the GPS and location services is not an option for me so I will have to wait and see if they have a new update soon that addresses the issue. A big problem is if it cannot get a GPS lock due to poor signal from the satellite it will consume a high battery amount trying to find the signal. For now I am able to charge my phone a little bit in the car to make up for the extra battery use.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
I'm really not having these issue and today is a day I'm actually using the maps and GPS... I'll keep looking at it and using and report my results... what ROM is everyone with issues running? Sammy or AOSP and which one?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] drock212:
Stock rooted. But I've reverted back to the older version of maps because of the battery drain
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
This didn't drain me at all today... I'll post a screenshot in a second... I used the maps for about 20 minutes, sat put for about 30, used for 20 more or so, and have left my phone alone since...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
maps

View attachment 1287038

i used that at about 7:45 in the morning on the way there, and just to use it, on the way back.... then left my phone alone until the time in the screenshot...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tripintaz:
I'm using Kyan Rom AOSP with stock kernel. After monitoring for a few days it appears that the only difference is the GPS stays awake longer than the previous version but that also means the GPS lock is usually immediate. The battery drain is not huge at all. I can still go a full 24 hours on my battery and still have life left.

So at this time it really isn't a big deal for me. If I know that I will need to have a really extended battery life I will just disable the GPS services for the day.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] AtoZ0to9:
So far the only people reporting this issue are on TW ROMs...
[Samsung Epic 4G Touch] Cipherblox:
I wiped and flashed the latest CM9 Nightly. While the first lock took a few minutes, all subsequent locks have been nearly instantaneous.

While JB vs ICS may make this weird, I'm going to look at the diffs over the relevant files. I'd be particularly interest to see the results of a bdiff (Binary Diff) of the GPS Driver across different ROMs.
[Samsung Epic 4G Touch] dohchp:
I used qualcomms qpst program and checked an extra setting under the gps tab and i get almost instant locks. You go through the steps like you are going to manually update a prl but stop at the click roam tab and scroll over to the gps tab. I will have to look in the morning at exactly what the box was that i checked. I did this about a month ago and i have faster locks than ive ever had with any phone.
[Samsung Epic 4G Touch] calisro:
Bump
[Samsung Epic 4G Touch] puch0021:
Please keep us updated with that program.

Another quick question for discussion. Are quick alterations to the gps.conf likely to make any significant changes, or is it all placebo?
[Samsung Epic 4G Touch] vinnythepooh:
After reading through the thread referenced in the OP I found the app mentioned on page 4. Even after i changed my build prop to GT-9100 the app GPS control SiRF refused to work. I emailed the developer to see what tweaks he is using underneath to enable the sleep mode on our SiRF IV gps chip. I'm awaiting feedback and will share any info the we might be able to apply into the Gps lib or through direct ways
[Samsung Epic 4G Touch] I'M NOT YELLING:
Where did you get this software from? I'm desperate to improve my GPS in anyway possible.
[Samsung Epic 4G Touch] mxmr:
Refer to this thread.
[Samsung Epic 4G Touch] Nannuq:
ok the information that Dohchp posted got me thinking so I started following what he did. However once to the GPS screen only the top box was selected and I had no clue what the rest meant so I searched and besides finding out what each thing means I found this site with a guide for blackberries. I decided what the heck I'll try before the hack it took 82 seconds to lock here in northern Idaho with mountains all around after the hack it took 17 seconds.

http://bbsoftware.weebly.com/uploads/1/7/9/3/1793039/gps_limitations_pdf.pdf

I take no credit for this since all I did was a little research. I have only had this on my phone for about 5 minutes now and will continue to test it out. if you screw up your phone that is your fault for not reading enough before doing stuff to it. If you are afraid to screw up your phone then don't mess with it.

Update: disabled GPS waited a few minutes turned it back on locked in 16s got 9 sats was only getting 4 sats before the modification

Not sure that is matters but I am using Calk's 3.0 GB rom and like Bigt2003's post below me I have been using Faster Fix from the market. However even with that I was getting the times I posted here in the valley.

update: 45 minutes after the mod. While standing in the yard I enabled the gps and had a lock in 24s. I then walked into my apartment to it's closest to center location and ,not surprising, Imidiately lost all satilites gaining them back with in 16s of moving back outside. Probably to much info but better to have too much than not enough.

Update: after just a few hours with the GPS left on but not mapping software running my lock is taking just as long as it did before 81s to lock all locks after that are sub 20s but that is after it's initial lock. So this method is a bust unless a slight variation of the settings changes something. There were no ill effects to doing this that I noticed.
[Samsung Epic 4G Touch] Bigt2003:
Don't know if it will help but I'm just reporting what worked for me. I'm using phantom's alpha 4.3 (jb) and I couldn't get a lock for over an hour. I had no satellites showing in GPS Status. I used Faster Fix from the market and set the location North America. I rebooted and locked on to 7/8 in 12 seconds. It may not be a technical repair, but it worked for me.
[Samsung Epic 4G Touch] calisro:
All you did was enable all the gps features?
[Samsung Epic 4G Touch] Nannuq:
Enabled and the info to the right as well the Ip address and such. I made it so that when I read from the phone It matched the screen from the guide exactly.

I must point out that once written to the phone, the phone will reboot. As is generally the case the GPS locks very fast right after a reboot, at least for me, so all this could just be that and not actually doing a thing to resolve the issue of getting a lock hours or days later.
[Samsung Epic 4G Touch] rocket321:
I had read the sirf gps chip was removed in the sph-D710 to save money and only uses the built in exynos chip for gps.
[Samsung Epic 4G Touch] Nannuq:
you are possibly correct about the chip since we don't have the sirfgps.conf in /etc that is in the international S2. Guess I'll start looking for a link showing it was in fact removed or not.

Update: It appears that Rocket321 may be correct after just a few hours my locks are taking just as long as before to get the initial lock. 81s so this possible solution is in fact not a solution.
[Samsung Epic 4G Touch] I'M NOT YELLING:
Good news on my end. I wasn't even getting a lock in CM10, at all, before this method. Mobile Odin'd back to EL29 and with that Blackberry guide I checked all the boxes in the gpsOne box, but I didn't enter in the IP or PDE port number. Flashed back to CM10 and had a lock in what I believe was the fastest I've had with this phone, ever (under 30 seconds). Accuracy was only up to 30-100 meters, though. I'll update this post again tomorrow with how goes the next lock.
[Samsung Epic 4G Touch] puch0021:
I think we need to distinguish between the "GPS problems"we have.

Problem A is a GPS that doesn't lock at all.

Problem B is GPS that locks after a reboot but after idling for a long time, GPS becomes non functional. A reboot however typically fixes this.

I have problem B for example. However, after lashing Dark_Knight's_GPS_Fix, I've had really good luck with GPS. I even get locks after extended periods and even indoors at time. Accuracy is typically around 4-6M with 8+ satellites.

Anyone else run that fix? Thoughts?

[Samsung Epic 4G Touch] I'M NOT YELLING:
Eh, woke up, went outside for a lock and didn't get anything at all. Just like it was before. Sigh.
[Samsung Epic 4G Touch] wotan2525:
I have the exact same issues. I've tried fasterfix and both gps fixes that have been posted on these boards. Have not had any success. I can get a GPS fix after maybe 5 minutes OUSTIDE with NO trees or buildings nearby. Once it locks in, if I move, I lose the signal again.

If I stand still the sats will slowly drop off and I'll be lost again. I took it to sprint and then wouldn't look at it until it's back to unrooted stock. That's my next move.
[Samsung Epic 4G Touch] Cipherblox:
Well there is next to nothing that Sprint can do for you. The problem lies in the software, not the hardware.

We have all proven that, at some point, we are able to get a GPS lock.

-------------------

Very interesting about the SurfStarIV not being included on our phones - great find. I suppose it is fine that the Exynos is handling those duties outside of the fact that it will be a huge battery drain.

Given that none of the above techniques have actually fixed the GPS, I think the RIL or GPS Driver seems to be creeping up as the culprit. Are the GPS Drivers (and Daemon) pre-compiled even with the source release? If so, we'll have to spend some time in IDA disassembling them and figuring out whats going on. If we have source for the driver, we can likely start looking at the functionality right away.

The RIL on the other hand will vary between kernels depending on how the developer has tweaked it. I think a majority of us are running CM9, CM10, AOSP JB Alpha 5. Sbrissen, PhantomPhreak, and one of the TeamEpic developers might be best to comment on their respective RIL implementations. No sense in us reinventing the wheel here.

-------------------

Thanks to those who did the testing with Qualcomm's tool. Interesting results!

For the record... My build does use agps. The error you put in OP is a permissions error or something else. Very few phones lack agps now.
[Samsung Epic 4G Touch] Cipherblox:
Thanks for the input, Chris.

It is a permissions error, but like you said it is because our phone doesn't use that file (The XTRA.bin is associated with AGPS data). Just in case I did a 'chmod 777' and it still said the same thing :)

Is there any chance you might be able to comment on the drivers for the GPS? If we feel like it may be the cause, is it something I'll have to disassemble or do we have source for drivers as well? (<-Thanks for all the work and any help you can provide!)

-GP
[Samsung Epic 4G Touch] wotan2525:
Actually, I think it is a hardware issue. Plenty of people report no issues with these phones and the GPS works great. My first Epic 4g Touch that I had worked perfectly. It was when sprint gave me a replacement that it stopped working correctly. I'm leaning towards hardware.
[Samsung Epic 4G Touch] chris41g:
what im saying is, my build of cm9 for your phone does use the xtra.bin.. there are a lot of different parts to the gps, some open source and some proprietary.. gpsd (the daemon) is a vendor blob we dont have the source for.
[Samsung Epic 4G Touch] Cipherblox:
Oh jeez - I completely misread your post - I'm so sorry.

Part of me is interested in disassembling GPSD and seeing if we can't improve/fix it in some way. Though there is likely a lot of different avenues to explore before I dive into ARM/THUMB code :)

-GP
[Samsung Epic 4G Touch] EllGuapo:
Agreed...

I've had poor results with the GPS since I got this phone a few months ago, which was quite a disappointment as I have the "shiny new" white model, but the GPS won't even lock indoors. In comparing with a couple other friends who have the same phone (older black models) they get locks indoors within seconds, where mine will never even see 1 satellite indoors. I can get occasional locks outdoors but am ready to call Sprint for a replacement to see if that helps.
[Samsung Epic 4G Touch] wotan2525:
I flashed back to OTA FF18 STOCK and have not had any more GPS problems. Locks fairly fast (although never indoors) but seems to work fine for Waze and gMaps.

This means that there is certainly a software issue here. Why exactly do we need a lock before we flash a new ROM? What can we do to simulate that? Is there some kind of hardware cache that the 3rd party roms are not correctly updating?
[Samsung Epic 4G Touch] scubabear1:
I discovered that my Stock case and holster from sprint was thecause of me slow/no GPS lock the second I removed it from the phone I get a 5-1 second lock even indoors
[Samsung Epic 4G Touch] cuezaireekaa:
yea i have a body glove case that has the kickstand and no GPS while its on. but as soon as i take it off, i get instant lock. found this out while i was on GB early on. phew. ever since, ive not had any issues on any rom, ever... as long as the case is off. craazy i know.
