Hi.
This thread is similar to the ones opened in Diamond and Raphael thread.
What is GPS lag?. It doesnt mean how much time take the device to fix the satellites but the arrow(of TomTom, IGO, etc) is stick to your real position. Symptoms:
1) When you start to drive the gps programs continues a 0 Km/h during some seconds (>= 3 seconds).
2) When you stop the car the gps programs shows the speed going down and reach zero 3 or more seconds after you stoped.
3) When you are driving and pass a bridge or a cross the cursor says you are 30 meters or more behind you. Lets say the gps arrow is a bodyguard driving 30 meters behind your real position.
The first day I didnt notice lag using latest Igo but yesterday I could notice it easily but much smaller than TouchPro lag. I ve checked that the gps drivers are the same than diamond's ones. For example, I ve checked that Samsung Omnia has ZERO lag for ever.

ive got the lag to, about 50-100 meter
I do too, after some tweaks to the gps settings in the registry I got the lag down to about 20 meters, still hard to navigate in innercity trafic tho
I've found this neat tool: http://www.nuerom.com/BlogEngine/page/nueDynamicClock.aspx
Has anyone used this on their X1 and did you notice any changes? I don't think you can use it for overclocking an X1. But I'm thinking about setting clock frequency to 19 MHz on Suspend, to get more out of my battery.
I've got this tool, not sure if it made much of a diff when I overclocked it to 528
( or just set it to the base clock speed since they have it underclocked @ 400 mhz ), wanna try the lower speeds, but not sure whether it will have a negative effect.
I uninstalled it..
found that any apps (such as gps cycle computer, audiomanager etc) that played with the screen on didn't work very well when the speed was lowered. Also had quite a lot of instances when the screen was corrupted after coming out of suspend..
I use it since yesterday, so i can't say anything about changed battery lifetime. But i got it working only after setting min-clock to 384MHz. With lower settings the phone got frozen in standby mode after a while. I'll try it for a few days for testing a (hopefully) enhanced standby time...
PS: i use 384MHz in suspend mode and after idle time of 5s, didn't change max clock or voltage settings (all to "auto"). Maybe setting idle time to 2s would care more battery life, but i don't know how the cpu will stand changing the clock so much often...
Been using it since v1.0. Seems to have some battery gain (10% over 8 hours better) - set to default 528MHz, down to 256MHz idle and 122.98MHz on suspend and screen off. Needed 123MHz for clean audio playback in standby.
Only screen corruption (inversion) issues I had was when set too low (19MHz) at standby. Now using these settings for a few days and no issues so recommended for use with TFlo3D2.
Unless you're running WM6.5 with WM7 titanium - makes it very slow to respond out of standby.
And it doesn't overclock - 528MHz is default clock speed.
I wanted to try this but my X1 says no, here is the screen shot, due to security, I press yes and my X1 does a soft reset, then I try the program again and get the same thing.

Has anyone with a standard Official Rom 2 got this to work, and how ?

I have a standard R2A ROM and it works for me. Can't tell you what's the problem with your installation, though.
Anyway, I found since I installed the tool my device is worse than before. It sometimes interrupts audio playback when display is off (ALthough frequency in that case is still at 3xx MHz!) and sometimes it takes very long (5 secs +) to suspend and to wake up again. So I think I'm gonna remove it.
I only turned down the voltage to 1.1 instead of 1.325 running on 528MHz.
Hi all
Today I was playing around with some new music players and it seems my hero can get very laggy when playing back music and doing other tasks at the same time (not always, but especially when the phone is just woken up).
I decided to have a gander at top to check cpu usage and load averages. The cpu usage was hovering only at 10-20% yet the load averages were always at a minimum of ~5.5, which sounds pretty nasty.
I decided to see what they where after the phone had been sleeping a while, so I checked using "uptime" several hours later instantly after bringing it out of sleep. I was shocked to see 164/131/66. These seem completely insane.
So:
Are load averages broken in the kernel, is my phone broken or am I missing something?
I suspect it may have something to do with the way it records uptime (system time awake only)?
21:30:30 up 8:49, load average: 131.45, 185.11, 161.56
would be interesting to know how this works. i'm gonna set up a script that pulls this all day and logs it to a file, just for fun.

lol sry, i know what the "uptime" command does, just want to know how the load avg thing works on the hero. afaik a load of > 100 would result in an totally unresponsive device. and having the phone idling for several hours should not produce a load avg of 131...

Oh Sorry for my misunderstanding!! English isn't my first language,, just want to help!
no problem, this was actually my fault, i should have stated it correctly. i watched the uptime over night, but before that i did a reboot, load avg didn't leave the range of 4 to 6... no real information there i guess, looks like android has f*cked up the load avg "system"...
Seems lot of people is having GPS issues. Difficulty to get a FIX, poor precision.
So i'm starting poll to see if it's general or only some are having problems.
Here is the test protocol :
- Download 'GPS Status' from the market
- Go outside
- Wait for GPS Status to get a fix (it can take 5 to 10 minutes)
- After the fix, count how many satellites the GPS detects, the number may increase slowly until it stabilise.
- Note the précision range you get.
If you have multiples android phones, repeat this test with the others ones to compare. Better to do them at the same place, same time.
Post your results : Phone model, Rom version, time to get the fix, number of satellite, précision, cloudy or clear sky.
Here are my results I did two days ago with 4 phones, cloudy sky :
- htc hero with cyanogen 6.1 => less than 1 minute fix, 9 satellites, precision 6 to 9 meters
- htc desire with stock sense => less than 1 minute fix, 9 satellites, precision 3 to 5 meters
- htc desire HD stock sense => 5 minute fix, 5 to 6 satelites, constantly loosing the fix. precision between 15 to 30 meters
- htc desire HD, cyano 7 RC2 (my phone) => 5 minute fix, 5 to 6 satelites, constantly loosing the fix. precision between 15 and 40 meters
Today, sunny day :
- Samsung galaxy S official froyo rom : 1 minute fix : 6 to 7 satellites, precision 10 to 15 meters.
- htc desire HD, cyano 7 RC2 (my phone) => 1 minute fix, 6 to 8 satelites, precision between 13 to 20 meters
Things are better than on a cloudy sky, but still far behind the hero or desire.
HTC desire HD
7 satalites,, error or 6m, but here the annoying thing!!!
in locations and google maps it places me about 1.4k away from where I actually am and the placement that it reads in those are the exact same that it's reading in GPS Status... so it's not an error of 6m it's an error of 1.4km!
i've restarted the phone and redone the factory settings tried with wifi/data/gps/ all it just doesn't seem to get a proper fix on me
DHD Running CM7 RC 2
Cloudy day: 10 satelites and error of 6m
Will try now and post it later.
Took about 20secs to get a fix:
-Sunny weather with some clouds
-Found 7 satelites
-error 9m
Position in google maps is perfect.
Using DesireHD, Android Revolution HD 3.1 with radio Radio_12.35d.60.140f_26.06.03.24_M2
Radio could be important to GPS fix i think.

Yes, maybe.
Mine is the recommanded one in the radio thread : 12.28e.60.140fP_26.04.02.17_M2
My phone is radio S-OFF, can i upgrade it without loosing root ?
To upgrade the Radio you need ENG S-OFF.
you wont loose root when you upgrade the Radio.
but changing Radio doesnt necessarily mean that you'll get better results. It could also be worse afterwards and the process can brick your phone, although unlikely!
did it again and got the same error only this time had 6 satellites and after leaving it there for 3 min it finally locked onto where I actually am...then lost it a minute later and there are now clouds... any radio pack I can download? and how to do it? i probably fall into a middle east Africa radio pack as I'm South Africa

Well, i'm wondering if GPS technology is not a little bit random. depending on the satellites position and other things. Sunday, i was on a park, clear sunny sky, light wind, no buildings, some trees. Couldn't get a proper fix.
2 days ago, i was getting a fix after waiting 5 minutes, then repeatedly loosing it for a short time. never more than 6 satellites and very poor précision.
Then this morning, sunny sky again, fix after 1 minute, 7 satellites, 15m precision, but not loosing the fix.
Now i upgraded the radio, but sky is cloudy again. 2 minutes to get a fix. precision 20m. 6 or 7 satelites. But when i let the phone alone on a table, it magically went to 9 satellites and 9m precision. Took the phone back in hands. the precision droped again to 15-20m and 7 satelites. Looks like the iphone antenna bug. Started to move the phone around me, the number of satellites droped again to 5. and so the précision. Seems very sensitive ! And doesn't seems any better with the new radio.
What is strange is that the Hero and the original desire have a much better precsion ! 9 satellite and 5m holding them in hand under a cloudy sky.
The good thing, is since i switched from my nexus one to the desire HD, i run 20% faster during my workouts

ah that is a plus side and yeah I can't understand while previous phones are stable but not the DHD, even tho as far as I know the antenna in the DHD is the same as the desire...how do you mess up that :/
Sitting in my truck I get a fix in about 10 seconds. I get between 6 and 10 satellites with 2-4m precision.

I had cm7 rc2 on here the other day and it was taking like five minutes to fix and google navigation lost fix in mid route about three times. Didn't take me long to restore my sense based nandroid.
Sent from my Desire HD pocket rocket.
I get a fix in some 15 seconds. It sees 9 satellites and gives an error of 6 metres.

I got a fix in 14 sec (warm fix, i missed it the first time)
with about 6 sats (was 9 at one point)
Cloudy day.
Error of about 14m. (was as low as 5 and as high as 30)
My Case-Mate Pop case is interfering with the GPS performance. Satellite locks take a significantly longer time to occur and the spread fluctuates from 10-40 meters. Satellite lock time and accuracy are much better without the case.
Anyone else having problems, try using your GPS without your case to see if it makes a difference.

Time to get a fix and accuracy is one problem I often get, which is annoying, but what I really don't understand is the way the phone looses the signal once it has a fix.
I've had various HTC devices over the years, all on WM until the DHD. ON my last phone for example (Touch Diamond 2) once you had a fix, it was rock solid. You could change apps or even have 2 different programs using the GPS and it wouldn't miss a beat. With the DHD it couldn't be more different.
For example, say I am in "Maps" and have a good fix and accurate position. I then search for a destination and select "Driving Directions". Google Navigator opens, and then starts searching for a GPS signal!!! It takes a while before it locks on and then works out the directions. Why does it do this!!?? If I then switch to another program, it does the same. So annoying! It's the same if I use GPS status to download AGPS info. I get a fix with GPS Status, but when I switch to another application the GPS signal is dropped and it takes a while to fix again.
STOCK ROM
ARHD 3.1 and reccommended radio.
Fix in less than 5 seconds.
8-11 satelites.
around 5m accuracy.
Couldnt get a GPS lock at all when roaming on my holidays.
LeeDrOiD v2.2.2 + Cingular radio (see sig for build number).
Fix in less than 5 seconds, accurate to around 20m then closes in to around 5m after a few seconds more. First time using GPS since moving from ARHD to LeeDrOiD so I'm quite impressed. Tested outside of course.
