Are we all Mad?

You know what, i look at this forum everday hoping to improve my phone. I don't know anyone else who does this, and those that know I do think i'm mad.
All i'm trying to do is get a good sigal on my phone. I've tried flashing every radio ROM and and its time to face up to it... we'll never get a decent signal on these things.
I get two bars in my house. Just put my sim into a nokia n82 and its constantly on full bars! 3.5g too constantly.
Have I got a duff phone? or are all these HTC TDs just crap at what their primary purpose is ... to connect to a mobile network properley?
Shame. i'm thinking of buying an i900 Omnia instead, Is this any better for signal strength? maybe i should use my old nokia 2110 from the 90s. prob has a better battery still than the HTC TD!

Just out of curiosity... Why are you posting this as a new thread in the rom development forum?
I'm also looking for better signal strength... Have been ever since getting my diamond. I've also flashed all available radio roms... But this is (at least in my experience) quite common with these phones... After a couple of month (and a couple of version updates to radio roms) for the most part resolved...

The diamond is the first phone which give me full bars at my home. Using .05 radio.
No probs at all.

I understand your beef with eh signal man but this is not the correct place to voice your issue as this part of the forum is for ROM development.
Have you tried other Radios too?

To see 2 or 5 bars - it is a question of programming. This does not mean, you will have a "better" signal on a different device.
On the other hand, your handset can be also defected.
BTW I think this is not the right forum to post this problem.

Because i've been trying all the radio ROMS here and they don't seem to make any difference to the RF. Maybe battery power is improved. I read that elsewhere that the poor signal was just down to the ROM.
Does a Radio ROM exist that actually improves reception?
Thanks,
Mark

Really? maybe I have duff hardware? Sorry if i posted this in the wrong area (hangs head)
Any advise would be great though. Just flashing ROM .5 again . I've been usign .7 and .11 also .8 but nothing spectacullar. Duttys ROM is great for all else though. These phones would be nothing without xda developers!
Thanks again

Ya YOU are mad posting this on the ROM section!

Please can someone move this thread into another section? I don't think i'm going to be able to sleep otherwise!

goodnite. now u can sleep.
ps: jus cudnt stand seein u get mad on ur own!

I have a complete opposite exprience. Before i had orange i had no reception in my house. Neither with the sim in my diamond. I changed to hi/kpn and got 2 bars inside and 2 outdoors (with radio .03). With radio .05 2 bars inside and 3 bars outdoors. With .07 the same as .05 only faster gps fix. Now with .08 i have 3 bars inside and 4 outdoors.

ill sacrifice a bar or two ANY day to have the coolest device in the world. im almost batman!

With duttys roms i always got gps issues, using swiftblades 6.0 lite now. I get a gps signal in my living room (near windows) which was not possible with older phones i used or with any of my girlfriends phones.
But i can tell you it was a hard way of trying roms and settings to get my diamond working nearly perfect.
I think its a good mix of a rom, radio and settings.
Only way is trying.
...its no advertise for the diamond. Its still a nice ppc but i prefer other devices.

I'm with you on this, if all we wanted was better reception we'ld never be buying these things. (Mine last almost a year at best) It's all about tweaking, playing & most of all coolness (My teenage kids will kill me)

[Q] Can the GPS issue be fixed in Firmware?

Hi,
the title actually says it all...
I'm planning on buying an Android phone in the next couple of weeks and the Galaxy S is my prime suspect. However, I don't want a GPS cripple since I plan on using the GPS a lot. The lagfix seems to be coming along nicely with lots of different implementations and Sammy also has plans to fix it, so I'm not worried about that, the GPS trouble on the other hand seems to be very hard to catch and might be hardware related. Has anyone found the cause for the strange behaviour yet? Are there hardware differences between the Galaxy S and the Epic 4G GPS (which apparently won't make it over the pond to Germany). And last and least, is there any real alternative to the Galaxy S coming out in the forseeable future? I'd go for the HTC Desire, but it's SOC just can't keep up with the Hummingbird performance, so it's not really an option...the Droid X is too well locked, so XDA Developers won't be able to provide such a wide vaiety of mods and updates (and that is the most important thing to me since all manufacturers seem to drop support for their "old" devices after about 6 months...)
Any information and advice is appreciated!
Thanks

GPS Problems are software related mate.
There is a "fix" under test, that uses Epic 4G files. Works quite nice, i got a lock at home, with 10meters.
Some people claim that the new OFFICIAL Sammy software JM1, improved the GPS as well, people started getting a Lock at home with 10-30meters.
So yeah.. it is Software related, nothing to worry about.

Thanks!
All the fixes I had read about so far were just augmenting the GPS with Wifi and 3G data to smooth things out and did not really fix the problem. I read about the Epic 4G firmware thingy but can't fin the thread anymore, I'll have to dig a bit deeper and see how things are going there. Let's hope it really is only software and not some defective chip or component interference...

Well.. Currently, actually, there is no proof either way. By the end of September, it is likely that if problems still remain, they are hardware flaws.
I personally believe the main problems are software.

I'm on JM5 with Epic4G "fix". Not much improvement I'm afraid. I get stationary locks, but none while moving. Also, while stationary I seem to "jump" around. Not very optimistic about the whole thing. But let's wait for that september fix and see then what is going on.

And the strange thing is, the problem is not permament.
I get almost always a lock in 20 sec with 5m accuracy.
But if you primarely want a gps device with an android "add on", why not look at the garmin gps android phones?

Well, I'm not looking for GPS with a phone, I'm looking for the best Android Phone with good GPS...

Only samsung knows the answer. But since there seems to be such a range in severity and after all this time samsung has still not provided a real fix it could very well be that its hardware related. Well find out in september.

The saddest thing is that Samsung still has not really commented on this. They claim that there is no GPS problem on the Epic 4G which should mean that they know about the issue, but they never said a word about the cause or possible solution or whether all they can do is augment the GPS to make it seem more accurate and smooth.
Maybe some GPS chips were faulty/dodgy and that is why not everybody has these problems...if Samsung would fess up and admit where the problem is we could all rest in peace instead of all in pieces...

They've said they are optimising the GPS though.. The reason why developers generally don't explain patches in detail, is because there is no easy way to explain it. If they said "the GPS chip required GPS packets to be processed more consistantly, and change blah blah blah in GPS stack", only techies would understand whats going on.
Easiest way to understand, will be to diff the SGS source code when new code is released...

Well, I'm not waiting for technical mumbo-jumbo from them, but I'd like to know whether there is a fix (e.g. new GPS driver or something) or whether we'll have to send in our devices for new hardware.
The "optimizing" is what worries me really, because to my ears that sounds like improving, not fixing. Improvements have been suggested on these forums already, most augment the GPS signal with Wifi or cell data which is fine but does not solve the problem at all. If Samsung is planning to "optimize" by activating skyhook or something then the device will remain a no-go for me, if they mean "fix" by optimizing and will put int he correct parameters or drivers or whatever to make GPS work then I'll be happy. The word optimizing is just extremely dodgy and does not sound promising at all...
UPDATE:
I just found this in a swiss forum...:
If you hold the SGS in your hand or have it in your pocket the GPS reception is really bad. If you hold it with your fingers without covering the back with your hand or put it in a pouch on the outside of your backpack it wors flawlessly. Apparently covering the GPS antenna in any way badly affects the GPS signal.
I have no idea whether this is reproducibly, but if any SGS owner here wants to give it a try please let me know whether you can support these findings.

I honestly never had(serious) issues with the GPS. I'm using JM5 With Ndrive 10, locks in 30 seconds it's a little inaccurate by a 20 or 15 meters, and very rarely loose fix.
but i think it is for covering the antenna.
I still take my N96 to my work only because it has Garmin.

[Q] [REQUEST] Can anyone make a mod/fix for wi-fi dropping at -88dBM?

Hi All,
I originally posted a thread about this in the General forum, but no-one seems to know how to fix, so I'm hoping one of the super-smart developers can have a go here...
Basically, since the upgrade from Froyo to Gingerbread, the wi-fi now drops at -88dBM even when there is a perfectly useable signal/connection.
Previously I could pick up much weaker wi-fi signals as this cut-off wasn't in place. I now struggle with wi-fi at home (even with a router that's only some metres away downstairs) and in hotels, with the wi-fi dropping out if the phone's held in a certain way etc. Incredibly annoying!
Someone on the Desire HD forum found the code snippet where it mentions the -88 figure, and has managed to change/remove this. It is suggested that this code "error" is part of a Broadcom driver update.
Is anyone able to create a similar uploadable mod for the Incredible S? It doesn't seem to have been incorporated into any of the custom ROMs available, and won't be fixed by HTC either by the looks of things. It's a big problem which many users have encountered since the Gingerbread upgrade.
My original post here: http://forum.xda-developers.com/showthread.php?t=1132261
Desire HD thread here: http://forum.xda-developers.com/showthread.php?t=1058450
Code snippet: https://github.com/LeeDroid-/Ace-2.6.35/blob/master/drivers/net/wireless/bcm4329_204/dhd_cdc.c#L1288
Hope someone can come up with a solution.
Thanks.

Just noticed there is also a thread and fix for the Desire S, that offsets the threshold value.
Desire S thread: http://forum.xda-developers.com/showthread.php?t=1051674
Hope someone can implement a fix for this phone then...

What I have noted when I have tested different ROMs is that with MIUI this problem wasn't. WIFI Connection was more stable and never drops. Might the fix has already implemented there?

I would like this to be cracked by the developers here too, if they can find a way

at cyanogenmod it doesnt drop
but somehow i want to use android revolution hd, without the wifi drop issue

I've mentioned it to Mike1986 (creator of Android Revolution) a fair few times but he doesn't seem interested in fixing it which is a shame. Hence why I am appealing to the other developers on here to fix.
If it's been done on Desire S and Desire HD, why not this phone?

as far as i know it's a kernel issue
so the unity kernel must be changed

http://forum.xda-developers.com/showthread.php?t=1058450&page=7
read that thread, basically to be used it has to be made into the kernel

That's strange - some people say it needs to be built into the kernel, however if you look on the Desire S forum (link provided in first posts), they have a fix included in one of the ROMs, and the kernel is the same one the Inc S uses, from MDJ.

Ill make the edit to -108 from snq's tread and Ill post a test kerenl for you guys to test and let me know if it worked. Look for it this afternoon US time Id say about 4pm.

[Q] So... GPS Fix?

Does anyone have a reliable GPS on one of the newer roms? I've been using Serendipity (the last version), and have still been having problems.
It wouldn't be a big deal, except I would like to using a cycling app on the phone, and that requires a GPS that doesn't take 10 minutes to lock and looses signal every few minutes. Never mind that it can't even pin point me.
Maybe I'm just not up on todays roms, but my question is the GPS working well?
Thanks!

Using search would have supplied you with about 10,000 threads on how unreliable the GPS is even with fixes, newer roms, etc.
It all depends on your hardware and if you got lucky. If it's truly that bad, especially on any rom, then warranty it.

What cappy said. GPS in these devices is terribly unreliable and there seems to be no rock solid way to fix this. Some phones hardware seem to work better then others, if it really bothers you warranty it repeatedly until you can get a decent timed lock. My dad refused the leave the warranty center until he was able to get locks on his device in less then 10 seconds. Obviously took him a while with these crappy GPS's. He ended up with a much newer revision of the phone not sure what build number but his GPS is noticeably better then mine on the same firmware. I have a 1010 by the way and yes the GPS is aweful. I don't really use it too much other then to find general location sso it doesn't kill me but I understand the frustration with something that Samsung could of very well done a better job at.
At any rate this question has been answered all too many times. If it really kills you complain until you are satisfied. I personally don't think you will be regardless. My dad still moans and groans about his GPS even after all his complaining.

baseband flashing

hi guys, can't find answer
1. Saw the officials update there's different basebamd for 3g and 4g, can I flash 4g basebamd onto 3g devices?
2. If it is possible, will I am capable of 4g when travel to America? They also are implementing 4g network in Australia. Read that the basebamd chip integrated 3g and 4g
3. Ram is 512 mb? Only getting 256 in settings
I wrote short cause I know you don't like read long
Thanks

apparently too many people here asking many similar of what so called "noob" questions so that the experienced users don't bother to look at this sub section and let alone answer it.
i am an experienced users myself, and making a rom isn't a problem for me, just tweaking around with stuff and make a backup with CWM, then i can stand up and say "i'm a dev" like ppl on these forums. I mean do you really think you are a dev by just making a few tweaks copied from other sources and post it on the internet claiming it is your own rom? Android is such a popular and open platform that it hardly has an unified development process like such from proprietary software like M$ and Apple.
figure out the answer after a long search and reading on the internet, apparently those things are not addressed anywhere else thats why i have to post the questions in the first place.
1. flashing 4g or 3g does not ruin your baseband, you just cant downgrade it once you flash a newer baseband (same like Apple devices). 4g baseband give you 1 more frequency to use (only available in US)
2. still, it is not possible to use flash 4g baseband and have 4g if you have 3g modem.
only the Tmos DS7 have 4g modem (4g use a lot more power and your devices just cant ultilised all that speed anyway).
3. ram is 512mb but only 256mb available to system, (don't know why?)
one more issues for you to vote:
do you feel very drowsy, dizzy or tired after like 10 or 15 minutes of using the device on 3g mode? i feel really bad and like vomitting, fkuced up bad -_-".
i want to return the thing but given it is such a value for money device (only 200 AUD), i think maybe better to find the cause and fix it. I suspect either:
the screen is too dark and low resolution is the cause
the 3g modem signal too strong and causing headache (had this thing before when using iphone and turn on wifi tether using pdanet)
maybe something wrong with the software, it seems to feel better when i use the US fw versions, and really bad on EU fw -_-".
does any of you have this same problem? lets vote ^^

RAM is 512mb but some of it is reserved for GPU usage.

ppreVic1893
I don't understand why it set aside so many MB of ram for GPU, even though I'm not running any games and just using the launcher to look at the memory available?

Because it internally saves that amount.
