[Thunderbolt General] sdnick484:
Since the phone is just running a version of Linux, you can echo new values to the correct places in the /proc file system. Install a terminal program, su to root and have at it. For details on what to change, check here.

E.g.

# cat /proc/sys/net/core/rmem_max

262144

# echo 524288 > /proc/sys/net/core/rmem_max

# cat /proc/sys/net/core/rmem_max

524288

By default TCP Window Scaling is enabled, so setting a (reasonable) higher buffer may very well help for high latency links. TCP will automatically climb to the highest size that's beneficial (in theory). You should generally set it to slightly above your Bandwidth Delay Product (BDP). This will be somewhat arbitrary since it's our response times will vary significantly depending on where you're connecting and tons of other factors.

Anyways, I'm curious to see how this goes. I just doubled mine (my default was 256K using the default kernel in Liquid Sense 2.6). Keep in mind these changes are lost when you reboot. There's ways to make them persistent, but this is probably better for testing.
[Thunderbolt General] Andrew C:
I got all the way up to 10,000 MTU before fragmentation started to occur! I didn't change the build.prop, I was just curious to see what the command did.
[Thunderbolt General] milan03:
I've been trying 524288 for the past 5 days, didn't see any performance increase at all. Should I double that?!
[Thunderbolt General] silvrhand:
net.ipv4.tcp_rmem = 4096 87380 16777216

net.ipv4.tcp_wmem = 4096 65536 16777216

Try setting these?
[Thunderbolt General] milan03:
Not sure what cmd line to use for that one. Did it work for you? btw LTE devices run on ipv6 full on.
[Thunderbolt General] silvrhand:
What tool are you using to login to your phone with, just rooted my so now I have to play with getting ssh access I would guess?
[Thunderbolt General] milan03:
Just Terminal from market. Root Explorer as well.
[Thunderbolt General] silvrhand:
cool, have a ton of linux experience but finally started to root around on my phone. adb shell works a bit better as I have an easier time typing.
[Thunderbolt General] yareally:
Setting up ssh with dropbear or sshdroid in the market is even easier than adb shell :)
[Thunderbolt General] milan03:
Perfect! Please post the tutorial how to tweak the buffer size that actually works hehe :)
[Thunderbolt General] silvrhand:
Yah I don't believe that the tuning actually works, what we may see is the fact that the window size is getting munged once it hits the LTE network which will kill your performance.
[Thunderbolt General] chef2:
not sure what this means

i did this @ 1500 and 1492 and both times got 5 packets sent 0 recieved 100%loss

what is the number in perenthesis? it says 1500(1520) and 1492 (1500)?

thanks for the input

EDIT: Doing these tests I determined that my max packet size with no loss is 1400(1428)

My build is changed to 1500 as per the OP. I should change that to 1428 i suppose?

EDIT #2 I went into my build prop file and it was listed as 1428 lol i swear i changed it before...

EDIT #3 lol. so i changed the build to 1500 and now i get no loss until 1472 when checking. does this mean i can set over 1500 and keep testing to find out how high i go? i need to change the build and restart before every test. like my next test will be to set it to 1600 in the build and see if i get no loss up until 1572 right?

thanks
[Thunderbolt General] GMoGoody:
Just some advice. I would not put your MTU higher then 1500 unless you are certain every network device/network stack[ Radios, Routers, and modems] can handle jumbo frames. For wireless the max size is 2272, and wired it is 9000

If default truly is 1428 all you are really doing is adding 72 Bytes of payload to each packet sent. In the grand scheme of things that really is not that much, and would not think you would see a dramatic increase in speeds.

---------- Post added at 04:10 PM ---------- Previous post was at 03:57 PM ----------

One more thing MTU does not include the Ethernet header so in essence setting it to 1500 you will see packets of 1514.

So in your 1500 Byte packet, or whatever size you set it up to 1500

[IP Header] [TCP Header] [Application Header - HTTP etc] [Payload - aka data]
[Thunderbolt General] chef2:
yea i stopped at 1500. thanks
[Thunderbolt General] Zeuszoos:
Hi,

On mine, there is no "default" MTU line. Could you please tell me what it is on yours for 4G & WiFi and I'll create it on mine? It should be universal.

Thanks!
[Thunderbolt General] Zeuszoos:
Hi,

Using "yareally's" directions (#30), I tried a bunch of values!

Btw, what do I tap to bring a typed line out again in my terminal (like F3 on a PC)?

The best I could do without packet loss (always either 0% or 100%) was as follows on my phone:

WiFi = 1472

3G/4G = 1412

In the Build.Prop file, are there separate entries for 3G/4G and WiFi?

If yes, what lines do I need to find (or create) and which goes to which value?

If no, what line and which value should I use? The lowest number?

Lastly please, when I enter in a value (build.prop), should I add 28 to the number that worked for me and put that in? So that;

1412 + 28 = 1440 (enter 1440)

1472 + 28 = 1500 (enter 1500)

Thank You!!!

Hey guys, is there an gingerbread update for hutchinson 3 Austria??? If yes, where can i get it from?

Regards
[LG Optimus 2x] Tommy0815:
There is still no gingerbread-update at all. Not in Austria or somwhere else in Europe.
[LG Optimus 2x] MightyWarrior:
when do u think is it going to be released?
[LG Optimus 2x] huibuh0815:
Hi,

I can just tell you the information that has been spread through germany: gingerbread shall arrive in October 2011. An exact date wasn't told (as always)

I think austria will follow simultaniously as there is - technically - no difference between the devices - we do speak the same language and the band is -afaik- the same ;-)

Only provider-settings and branding-work or there will be the thing with "oh before we can rollout, we will have to get the ok from google"...

So I'll be waiting until end of october and then get on the nerves of the LG customer support... AGAIN :-D

Cheers,

[HTC EVO 3D] :
Previously on my ipod touch 3g, milestone, defy and blackberries i have always wanted to use an anti glare screen protector i get off amazon. But with the evo 3d i have noticed that the colour seems to be washed out with an anti glare screen protector.

So heres what i want to know:

1)Do you guys think the anti glare screen protectors for about £4 off amazon are really anti glare

2)Is it the anti glare screen protector washing out the evo 3d colours or is the problem apparent with all screen protectors

3)whats the best screen protector you guys have used?
[HTC EVO 3D] Sh0wNuF:
First thing I bought for this phone was an invisishield anti glare protector and it washed the colors out as well. I've also seen multiple posts in the accessories section saying the same thing. I've heard that the phantom skin normal works really well although I haven't tried it. I ended up just getting the 3 pack from Sprint and I'm still on my first one ant it works perfectly
[HTC EVO 3D] mozman:
I have the anti glare screens from bodyguardz. I really like them. I don't think the colors are washed out. Maybe a bit, but it really does cut down glare.

Be aware of the version you get from them. My first set had a halo effect. Which is where the very edges do not stick to the screen properly. But a quick call to them and they sent me a replacement free. This one was manufactured (I'm told) differently and works perfectly.

Sent from my EVO 3D
[HTC EVO 3D] :
interesting. the one I got off Amazon was

4 quid so it should be ok.

But do you guys think the glare reduction is worth the colour reduction?
[HTC EVO 3D] Sh0wNuF:
It wasn't for me
[HTC EVO 3D] mozman:
I think it's worth it. It doesn't bother me. I agree it is not the same and not screen protector or a clear one. The I don't get any glare or reflections. Since you already ordered one, you will have it soon and can let us know what you think.
[HTC EVO 3D] :
Ive already got one on my evo 3d and for £4 it's pretty impressive. yes it does help reduce glare a lot and it feels quite nice but it does wash out the colours a little :(
[HTC EVO 3D] stanglifemike:
I don't like the anti glare protectors at all! The 3D has such a beautiful screen and I refuse to take away from it with a screen protector. Zagg, horrible, don't even want to go there. Otterbox, makes nice protectors but i felt they degraded screen quality just very slightly. I am now using a FLSuperstore clear screen protector and absolutely love it. Fitment is 100% perfect, and you can't feel or see that it is even there. I was skeptical of them cause they were so cheap, but they have really proven to me that they are the best.
[HTC EVO 3D] :
I understand and agree with you. I compared my EVO 3s to my mate's desire s and the difference is astonishing. His one has a budget £2 clear screen protector which whilst has a lot of glare the colours look Amazing
[HTC EVO 3D] lchupacabras:
High-res screens are always CLEAR > Anti-Glare; why? Because the anti-glare make the screen look like a low-res screen... and then, what's the point?

I'm currently using the $1.50 cheapy and it's wonderful! Especially for the price.
[HTC EVO 3D] DarkManX4lf:
I think sprint sells a pack of three screen protectors and it includes two clear and one anti glare. I use the anti glare and its been fine for me. Yeah you notice the grain/specs but I can live with that.
[T-Mobile LG G2x] web_ninja:
i posted this in the G-Tablet thread and no one is helping there... Maybe a Dev can help me out on this...Is there any possibility of porting G2x or O2x roms over to the G Tablet? what are the differences? and are the partition mappings different? there are some awesome Roms I am running on my G2x right now, and was just wondering.... :D
[7 Mozart General] Jacobp100:
Hey,

My phone can often get into a state where the graphics become very messed up, like shown in this video of somebody who has the same problem. It can not happen for a week or so, or can happen multiple times in a day.

It was originally an Orange locked phone, which I unblocked, followed by getting an unbranded ROM, and finally installing the official Dev Preview of the Mango build. I have had this issue since the unbranded ROM, though it could have been before, as I put the ROM on after a week.

Is the problem with the hardware, or is it something I could fix with a new ROM or the official Mango update?

Thanks for your time.
[7 Mozart General] 7thSense:
Do you have the latest firmware for your phone?
[7 Mozart General] Jacobp100:
Think so. It says 7.10.7712.60 Mango Dev build.

But I had this before on NoDo and the one before that.

Thanks.
[7 Mozart General] 7thSense:
That is the OS version, not the firware.
[7 Mozart General] Jacobp100:
Sorry, it's: 2250.09.12306.401
[7 Mozart General] 7thSense:
You could try applying the Mango firmware from the developer forum. Then you will get 2250.21.40600.401. It may or may not solve your issue.
[7 Mozart General] Jacobp100:
Would I get this update with the official Mango update?
[7 Mozart General] 7thSense:
As far as I know: no.
[Vibrant Q&A, Help & Troubleshooting] Rat48:
I had Trigger 3.1 ono my phone and wanted to go with nero 3 beta. When I installed Nero 3 beta my phone froze and was stuck on the logo nonstop. I used odin and reloaded the stock vibrant T959 software. My question is can I install a rom on the phone after using odin and fixing it, or do I have to root it and so on.

I bought the phone rooted so I don't quiet know how it was done and what was done to it.

Thanks in advance.
[Vibrant Q&A, Help & Troubleshooting] roogerrisboredd:
No you don't have to root it if you can keep a copy of cwr on your sd card and move it back into your phone storage when you lose it. People who flash roms usually only root their phone when they need to redownload cwr through the root required app.
[Vibrant Q&A, Help & Troubleshooting] Rat48:
So all I have to do is get into the recovery mode and choose to install from SD card and load for example bionix v. 1.3.1? By the way is Bionix v 1.3.1 a good rom? I'm looking for something that will be the most stable and won't drop calls or have problems with searching for signal.

Thanks!
[Motorola Droid Bionic] SciFlyer:
I noticed that the powersupply (AC plug) for my HD dock is very sensitive. If it is not plugged in to an outlet just right, the phone does not go into "dock mode" and it doesn't charge. If you wiggle the transformer a bit, you can get it to work.

I think it is all because of the fact that the plugs fold into the transformer which makes them sensitive.

I am bringing it back to verizon for a replacement.

Does anyone else have this problem with their HD dock?
[Motorola Droid Bionic] spongers:
I have this dock and I do not have that problem since I bought it.
[Motorola Droid Bionic] SciFlyer:
Update: I exchanged the dock at the Verizon store and this one works fine

I have the evo 3d and also the optimus 3d and trying to decide which to keep and which goes ...... now ive taken pictures on both , the evo 3d is brighter on the screen when viewing the picture but im wondering is there a filter on the optimus 3d ?? reason i ask is when i view the pictures on my pc the pictures appear lighter ..... im really at a loss as to which one to keep ... can anyone help me decide please ..

i like the 3d software on the lg but i also like the sense on the evo ??

thanks
[LG Optimus 3D] ananth010:
Hi,

Yes, Lg optimus 3d does have a darker screen. But I gave up my HTC EVO 3D for LG optimus 3d coz HTC has not bothered to do anything with 3D! Surely you have noticed LG has better 3D, altough HTC is faster.

mind you it isnt straight from china, but its exactly the same, and has evolved since cm7 came out
[HTC Sensation] geoffcorey:
The have, many time, but it's been deleted because the devs was banned from xda and has requested his work not be linked on xda.

Also, wait until CM7 source branch is opened, then we will more than likely get a direct miui build and not just some port (all current miui builds for sensation are technically frankenbuilds because only the few working on CM7 for sensation have working rom source for it).

I'm having an issue on my GS2. The alarms work fine, except i can't snooze them. I slide snooze and the alarm turns off as though i had dismissed it. I have no issues with installing an alternate clock, i just wanted to make sure it's not just me being unable to figure out my phone.

[Samsung Epic 4G Touch] daneurysm:
It's been working fine for me. Though I wish you could pick other ringer sounds. That stupid alarm sound is downright relaxing. I need my alarms to be a little more upsetting....though I do find the SmartAlarm with debriefing pretty cool.

That reminds me how much I love this speaker.

EDIT: nvrmnd. I only looked at 'alarm type' not even 'alarm tone' which is where the file selector is.
[Samsung Epic 4G Touch] franco523:
Fixed?

Hey, hey, Good news!

So, apparently this was one of those issues that you merely need to bring up in conversation for it to get fixed. This morning i snoozed and it went off 5 minutes later. Interesting. I'll monitor this behavior.

Hi all,

Great forum. Good folks here :)

BIONIC XT875

I'll get right to it. I'm trying to make sure that adb will be working from the command line, but I'm a little stalled on creating a rule for udev.

lsusb in "normal" and "debug" modes produce different results from my pc... and a third differing ATTRS{idProduct} from the Bionic directly.

Would someone be kind enough to clear this up for as to exactly what will need to appear in my udev rule OR post a working example of theirs?

Many thanks,

[Android Q&A, Help & Troubleshooting] bearmonsta:
I use a small free program on my desktop called 'Connectify' compatible with any WiFi device. It works by creating a WiFi hotspot from my wireless usb card to allow me to share my internet connection from desktop to devices. It is the most simple program to install even my not so tech savvy family members can understand it.

I have no knowledge on how to set up WiFi on your phone though, but a quick search on google on how to set up wifi on the wildfire s will net you many answers to that.

You can also install Connectify on your phones and laptops (optional) in order to share their internet connection. If this program isnt suitable I could help set up your WiFi if you have a wireless modem you could tell me the name of.
[Android Q&A, Help & Troubleshooting] febycv:
To share your mobile connection with your PC, you need to use an app called EasyTether. You can download the app here.

EasyTether shares your Android smartphone connection with your PC. This app allows you to tether your Android to a desktop or a notebook computer.

Ok, I'm rooted my Eris, and I've installed a few different roms over the last 14 months, with success each time, but with each new rom I end up having to reconnect my phone to my car's bluetooth.
