HTC EVO 4G :: Poor 4 G Performance?
Jul 13, 2010
Am I the only one, or is there a problem with the EVO and 4G speeds? In the Houston Area, I get anywhere from around 600 kb/s to 2600 kb/s speed. In most all cases, the 3G speed is faster than the 4G. At home, I average around 700 kb/s with 2-4 bars signal strength showing. Tech support is working on this with me and trying to determine if it's a phone problem, or tower problems. I had a chance today to journey around the area within about a 10 mile distance, thus insuring it changed towers. Service stinks on 4g, to say the least. Clearwire tells Sprint Tech Support that the tower for my home has low use, and good throughput. If the tower is good, and the software on the tower, then there may be a HTC EVO problem of some kind as this is the same on 3 different HTC EVO's purchased within 2 days of each other.

I have a map in my android application that shows many markers (~20-50). But the app performs very poor when i try to scroll/zoom (in Google Android Maps i did a sample search for pizza and there were also some 20-50 results found and i didn't notice any particular performance problems when zooming/scrolling through the map).
onCreate() {
....
drawable = this.getResources().getDrawable(R.drawable.marker1);
itemizedOverlay = new MyItemizedOverlay(drawable,mapView);
...
callWebServiceToRetrieveData();
createMarkers();
}..............................

So I'm doing some simple 2D stuff with OpenGL on Android and found the performance to be very, very poor. To give you an example, I made an app with a full screen LSurfaceView. I loaded a 512x1024 texture (containing a 480x854 image), set up an orthogonal 2D matrix, and set it to draw a 480x854 pixel quad with that texture, using vertex and texture arrays. Lighting, dither, blending, etc. is disabled.
I would expect this to run at 60fps without problem, but that simple operation already drags the frame drawing time to 19ms/frame. If I add some more small textured quads around the screen, the drawing time goes up to 22/24ms. If I enable blending it balloons to 28/30ms. This is testing on a Motorola Milestone, running 2.0.1. Is this normal? Am I doing something wrong or is it just a common problem in Android?

I just got an HTC Magic from Rogers a few days ago and I'm noticing that it's running REALLY slow. The lag is unreal when I text and the battery dies very quickly. I have TWO widgets open (calendar and Google search) and the transition from sliding screens is sluggish. I rooted my phone a few days ago. Could this be the problem? Has anyone else experienced this? I heard that Sense UI is supposed to cause problems, but I haven't heard anything regarding Cupcake.

I have no issues with GPS with my stock 1.5 ROM. The signal is picked up within a few seconds, even in my basement. Once I updated to Galaxo 1.6.3.2, the gps performance is extremely bad. Most of the time, my phone is only picking up 2 satellites, not enough for a lock. If I am lucky enough to get a lock, it doesn't last very long. I have managed to pick up 7 satellites once, but the reception on each was extremely poor, not enough for a fix. I tried flashing back to stock, which again, had very good GPS performance.
Does anyone have any ideas as to what underlying issue is causing the poor GPS performance? I understand that JC6 ROM (and Galaxo is built around it I believe) is from Russia. Does android have a cache of nearby satellites (similar to how QuickGPS works with windows mobile phones), and could it be that these satellite location are optimized for Russia? If not, is it an inherent problem with Android 1.6? As I use my gps quite often, hopefully someone can provide some insight, or I might just be driving an infinite loop of circles in the near future...

I have other non China android phones that records video pretty impressively under bad or average lighting conditions. According to MT6573's specification, it has support for advanced 3D graphics; multi-format video capture and playback up to FWVGA 30fps; high-resolution camera support to 8MP.
An irritating thing is that the camera is TOTALLY USELESS under average or poor lighting conditions when recording. I have tried with different apps and they all gave me disappointing video recordings (almost total darkness clips).

I have never had any problems at home with either my trusty unlocked N95 or Orange Sony Ericsson T610 (remember them?) so I had no qualms over ordering a nice shiny (dark brown) HTC Desire.
3G coverage is a bit iffy in the area as I'm right on the border of an excellent to good area so I never expected to have super fast data over the air, but I have wifi locally for that anyway.
So you can imagine my disappointment when the first call with the mobile from home cut off quite suddenly. A retry to reconnect failed with a no service message and no signal strength. I then spent the next hour playing around with the settings turning off wifi, data, setting the phone to 3G only (no chance) and then GSM only.
When the phone was working and making a call the audio was not clean and very digital. There was also a chance that mid call you would be cut off for no reason. When it wasn't playing ball at all the signal strength varied from three bars down to zero without moving the phone. Sometimes upon initiating the call it came back immediately with no signal and cutting the call off. Picking the phone up from sitting on the side in sleep mode you were usually presented with a no service message.
Orange were excellent and immediately replaced the phone, a courier arriving at 6:15pm upon reporting the problem at 8:30am that morning. Unfortunately the replacement was exactly the same.
Even worse, my place of work is in a designated poor reception area. There are a number of us on Orange as it is the only network that can at a pinch be picked up inside. My Desire...no signal at all. Moving to a window seat got me two bars but the phone refused to connect or hold a call. The only time it did calling 150 sounded like I was listening to a recording of a Darlek. A Nokia 5300 on Orange alongside was nice and clear, with very good tone by comparison.
By chance another member of staff also had recently signed up with Orange on a Desire (500mins, unlim texts, 500Mb, free phone, 20). In a back to back test both phones were the same. We even tried swapping SIMs. Luckily for him he has no problems with reception when at home so is quite happy with the Desire.
Contacting Orange again I did not get much further. Talking to technical support they were not much help and suggested that they did not warrant the phone to work inside the building and as I could make a continuous call outside then they did not class the phone at fault. This included my problems at home in what is termed an excellent coverage area! When I pointed out that two other phones I owned did work in the very same location I was told that mobile designs differ and positions of antennas vary considerably.
Frustrated I decided the only course of action was to use my right to cancel within 7 days as it was apparent that I was not going to be able to resolve the issue. Even last night it performed perfectly for a couple of calls and then failed miserably an hour later.
As a gadget I was smitten. Even as I handed the package over to the Post Master today I was inwardly screaming �GIVE IT BACK!� Unfortunately I need to be able to make calls on it when I want, not when it wants.
I have only seen a couple of other members note a similar problem on these forums but I have noticed a large number of Nexus problems that sound very similar. I would be interested to hear if anyone else has experienced this or do you all live in 5/5 coverage areas?

I'm encountering very poor roaming performance. When my device switch from 3G to Wifi and vice versa, my application can't connect to the INTERNET for about 10 minutes. The given error is connection timeout: socket is not connected. I've already posted a similar problem here: http://groups.google.com/group/android-developers/browse_thread/threa... But I've noticed that it's not related to HttpUrlConnection. I've tried Apache Api to make my connections and the result is the same. Am I the only one facing this problem ? Could it be a platform bug?

I see some people in the forums bragging about how great their batteries are and i am jealous I took mine of the charger at 7:00 this morning and at 3:00 my phone was already down to 40 percent. My question for the users that also seem to have poor battery life is, once your phone reaches 40% does a reboot give you more battery life? Every time my phone reaches 40% a reboot brings mine back up to 60%. This happens every time so it is not a coincidence or a onetime thing. I am curios if the reporting is off because it is almost 5:00 and i just did a reboot and now I have 60% left. I can live with 40% usage from 7:00 to 5:00 but I can't live with 60% usage from 7:00 to 3:00

What's up with Yahoo mail on the Moment? Its performance is absolutely dismal! I followed the steps in manual set up instructions I found in a thread here:
INCOMING
Imap server - imap.mail.yahoo.com
port - 143
security type - TLS (if available)
OUTGOING
SMTP Server- smtp.mobile.mail.yahoo.com
port - 25
security type - TLS (if available)
* check Require sign-in
I was able to establish a link with my Yahoo mail account, but is reliabilty and performance is poor at best (I had much better performance accessing Yahoo mail on my old Samsung Instinct). Most the time when I try to check my Inbox, I get a "Username or password incorrect" notice. (Believe me, they are not incorrect). If I press "Menu" and then the "Refresh" button, I then get a "Connection error" notice! If anyone has any fix or any info for resolving this issue, then please post it here. I can access my Yahoo e-mail okay through the browser, but this is really not the way I prefer to do this.

I just got my Motorola Droid and installed my little accelerometer app right away. All it does is registering a SensorEventListener if the user clicks the start button. It also takes the current time in millis. Every time onSensorChanged() is called, a counter gets bumped. After the user presses the stop button, the listener is unregistered and the time taken again. Using the values from above, I get a samplerate of 9 samples/sec which is WAY too low for what I want to do. The delay of the listener is set to SENSOR_DELAY_FASTEST. The Listener is registered within the main activity and is executed on the main thread of the process (I guess).
The G1 we used before was getting samplerates from around 35 samples/ second, which is way better, but still bad. Any suggestions on why the SensorEventListener performs poorly? The system is Android 2.0. App is compiled using API-Level 5.

I am trying to display one png (drawable) on a map in about 300 points. I am retrieving the coordinates from a Sqlite table, dumping them in a cursor. When I try to display them by parsing through the cursor, it takes for ever for the images to be drawn, about .5 second per image. I find that to be suspiciously slow, so some insight on how I can increase performance would help. Here is the snippet of my code that does the rendering:
while (!mFlavorsCursor.isAfterLast())
{
Log.d("cursor",""+(i++));
point = new GeoPoint(
(int)(mFlavorsCursor.getFloat(mFlavorsCursor.getColumnIndex(DataBaseHelper.KEY_LATITUDE))*1000000),
(int)(mFlavorsCursor.getFloat(mFlavorsCursor.getColumnIndex(DataBaseHelper.KEY_LONGITUDE))*1000000));
overlayitem = new OverlayItem(point, "", "");
itemizedoverlay.addOverlay(overlayitem);
itemizedoverlay.doPopulate();
mFlavorsCursor.moveToNext();
}
mapOverlays.add(itemizedoverlay);
I tried to isolate all the steps and it looks like the slow one is this: itemizedoverlay.doPopulate(); This is a public method in my class that extends ItemizedOverlay that runs the private populate() method.

With Advanced Task Killer, which apps should I exclude to avoid poor app performance. For example, I realized after reading another thread today that I should exclude the Weather Channel widget. I could not figure out why the weather conditions did not update automatically. Excluded the widget and now it updates. Any other apps that are similar?

I use to own a palm pre before I switched to HTC EVO. I think the evo is a great phone but the two things I missed so much about my palm pre is the camera and the sound qualities.
The EVO is said to use 8MP for its camera but honestly the camera quality is nothing compare to the palm pre. Simply put, the camera and the sound output on the evo sucks.
You can clearly notice the difference between the pictures I took using the pre and the evo. The pre gives far better picture quality and also better sound output. I always enjoy plays my sounds or using pandora on my pre, but with the evo the different is the case. The sound quality with the evo is horrible even when plugged to good speakers.
I bearly take picture with the evo because I am used to good picture quality with my pre.
I have had the evo for less than two weeks and i am seriously thinking of returning it because of these two issues.
I really want to know, is this poor picture and poor sound qualities a thing with the evo in general or is it just with the particular evo that I got.

I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks.This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here.This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

I (like hundreds of others) have had a call quality problem with the two Droid Incredibles I purchased for my wife and myself when they were released on April 30th. Verizon recognized that there was a problem and replaced both devices with ones manufactured about a month later (5/02) and the same issue with poor voice quality continued.
We love the device EXCEPT for the lack of ability to understand callers. So, I asked Verizon to extend our 30-day opt out to give them an opportunity to work out the issues with this device. I just received a call from Verizon customer service (which I could barely understand) and was told they would not extend the 30 day period and my option was to live with the poor sound quality or switch to another device. Verizon has no other devices that were interested in at this time so well be canceling these two lines (and one other) and returning to T-Mobile. T-Mobile may not have the best coverage, but they do have great customer service, unlike Verizon.

Does the Inc inherently have poor signal strength? or do i have a dud?

I don't know if this is because of Sprint or the EVO but in my house I barely get 1 bar of signal and people can barely hear me on the other end of the call. This is my first Sprint phone so I don't know if it is the service or not. I came from ATT and never had these issues with my iPhone before. I am a little concerned about whether I exchange phone or am I going to just have to give up on Sprint.

Is anyone else experiencing poor Bluetooth reception? Have my wireless bluetooth headset that I love so much. On my Samsung I could walk two rooms away and it would be fine. On my EVO I get constant reception problems. If I step more than 5 feet from the phone its awful. Even walking around with the phone in my pocket its just awful. What the hell is the deal with the EVO and its reception problems?

When i m indoors, if I switch to GSM only mode, the reception is excellent. But when I m on WCDMA mode, then the reception drops alarmingly to near zero. At the same spot, a Nokia E51 shows near full strength signal. If I move towards the door, the reception improves. Does the desire have issues with indoor reception? Or is it just my handset?

I went for a drive today and put the Evo on the mount I built for my car, plugged it in to the radio and also in to the car charger. I have Slacker Radio set to leave the screen on as long as it is connected to power. My battery was probably about 95% and during the drive, it was charging and, while listening to Slacker, the screen stayed on. However, not long before I reached my destination, my battery got to 100%, the green LED was on, and the screen would follow the 30 second shut off that my phone is set to. I could no longer get Slacker to recognize when the phone was connected to power. Anyone have a similar experience? I'm hoping this was isolated to that one instance (some perfect storm of other settings, use, etc), but I have a feeling it isn't.

I'm having a weird problem with GPS accuracy. Basically, I check the GPS accuracy in a background thread after the user clicks a report button, and show the accuracy in a progress dialog, changing second by second. (Code is below.) The following strange thing happens:
1. If the user clicks more or less immediately on the button after taking the phone out, accuracy is unsurprisingly pretty poor to start off with, say more than 100m. But the accuracy never really improves very much while the user is running the background thread. There is some improvement, but it's slow and it never gets very accurate. 2. However, if the user gets the phone out and then waits for several seconds *without* clicking on the button and running the background thread, and *then* clicks on the button, the accuracy quickly improves and becomes very good. When they click on the button, the accuracy shows up as fine - within the same length of time............

I have just got hold of a Tattoo on the Vodafone network and i am finding that at times the signal strength is very poor.
I am finding that in places i used my previous phone and had a good signal that the signal is dropping out or there is no signal at all.
This is very frustrating as whats the point in having a decent phone and not being able to use it?
Normally the Vodafone network signal is very good.

poor signal reception been fixed yet? I'm interested in buying either a new sim free desire, x10, or a blackberry bold 9700. Leaning more towards the desire, but the only thing holding me back is the poor reception problems people have been experiencing. I'm on orange, and based in the east midlands, UK. Not had bad reception in my area with other phones in the past, so if got the desire and did have problems, it would annoy me to say the least

Since having the HTC desire I have noticed that my Vodafone reception is very poor. I am sure it has something to do with the phone because I never had the problem with Sonyerikson. Now overtime I have no network I have to turn off HTC desire completly and turn it back on to have network, which works.
