GPS suddenly Not working, in any application,

hi, i have had an unusual issue in that the GPS on the device does not work any more, it did before around 2 weeks ago when i used google maps with the compass working as well.
i have tried soft resets and to check the com ports (i am unsure of the defaults for com port, is it 0?) and have tried to set them manually and also to allow the device to automatically set them. The digital compass has allways been working.
i have installed a fue gps applications recently, since i last used the gps successfully, and have noticed the gps not working in any of these and then not working in the pre-installed applications;
(installed in descending order)
-iGO 8
-GPS sport computer
-wifi fo fum 2
-GPS speedo
-hd speedo
-gps cycle computer
i have uninstalled these since and the GPS still is not being picked up in the digital compass application and google maps (both the preinstalled apps on the original ROM out the box, and were working with gps around 2 weeks back).
i have made sure i am always in clear sight of the sky, but no prevail their.
if some one could please help me on what to do to regain the functionality of the gps again, i would be great full.
p.s. has anyone else had this issue or a similar one?

Try downloading something with setelite tracker. GCZII is such application (good for geocaching btw).
Sometimes, the GPS has wrong satellite data. You will see (on the satellite tracker) it can receive some signal, but the satellites will not show above you, but let's say all to the north.
Go to start/tools and run QickGPS and download new data. That should help. It will download current data via internet. But it may help not. Sometimes bad data on these servers are the source of the problem.
So next thing you can try is use file explorer and go to Temp folder. There is file xtra.bin. That's where the data are stored. Try to remove it and soft reset. Try running your GPS without the file. It will take some time to fix (up to 5 minutes), but it should work.
If that does not help, QuickGPS will get the file back. I had problems like this on X1 .. usually something helped, either refreshing, or removing the file. On HD2 I needed it once, and refreshing the data using QuickGPS helped.

I'd suggest to try htc's own gpstool and see if you get anything at all on com4. search the forum for htc debug tools, the exe is in that package. And...disable quickgps and delete xtra.bin from \temp

Nice application .. I was looking for something like that ! Thanks !

thanks for the replies.
sofar i tried the qgps file removal with out success.
i have aso found something else out thats concerning, thats in igo 8 when i run a auto detect scan for gps device it come back saying their is no gps device.
it also seems to be the case when i ran gczll and the htc-gps-tool.
so i think that the gps driver? or device is the root of the issue?
hope this helps with the suggestions on how to resolve the issue?
Thanks for the helping again.

Aslo check settings/external gps.
First tab (programs) should be: COM4
Second tab (Hardware) should be: None, and 4800 (or anything I guess).
Third tab (Access) should be: Yes, manage GPS automatically

You're welcome ;-)
Have you installed any "tweakers" like BsB Tweaks, HD2Tweaks or similar? Have you messed around in the registry with drivers and such? I assume you didnt see any gpsdata at all on port com4 using the htcgpstool, what exactly happened when you opened com4?
Imho, if the above post by Sid doesn't do the trick, the easiest way out is probably a hardreset.
[edit]
what rom are you on, stock or custom, and have you never been able to use the gps or did this happen after a while, perhaps after you installed an app or something?

its stock rom, i havent ventured into cooked roms yet. (reading into it, getting a understanding of it all over last 2-3 days)
haven't messed around with the registy of bsb and dont have htctweaks (not sure on how to do that yet)
nothing happens when i run the htcgpstools, on com 4, same as it does nothing on any other application. it just continues to look (for a long time) or says no gps (like in igo 8).
im thinking that hard reset my be the best option as well.
could something have happened to the radio and broken down the communications of the gps device? (im not a expert, just a theory?)
and just on a cooked rom question.
i wanted a rom that has copilot removed and the full ram enabled, and just to include the performance update drivers (i have adk 1 runtime atm that improves the jitteriness) and other updates that hot fixes have done. but i want to keep stuff like animated weather etc.
from what i have seen it looks like dutty is the man for this type of rom?
could you recommend a cooked rom for a first timer/noobie?
Thanks.

I had a similer problem on my Touch Diamond.
Try switching off.... take the battery out for 1 hour, reinsert battery then turn on. I think that the GPS locked up.
Good luck

Hmm, you might be right. I still believe your best shot is a HR...

OK well did a hard reset and that has done the trick.
The GPS works and locks with in 10seconds from my window so working brilliant again.
Thanks for all the suggestions and the time taken to help out.

[Q] HTC HD2 with NexusHD2-Froyo V1.9G Android, app Google navigator freezes phone.

Hello, this is my first post on XDA-Developers forum. Hope I placed in the correct section/forum.
I flashed my HTC HD2 with NexusHD2-Froyo V1.9G from Tytung which I will render thanks for making the ROM.
Everything works fine, except of Google navigator, this app freezes the phone. I need to remove the battery to shutdown the phone and boot again. First i have run Android from SD-card and also then Google navigator froze the phone. Thought this might have to do with running Android from Sd-card. Was happy with Adroid, so flashed the phone with the NAND version. Still the same problem with Navigator.
When running Navigator, can search location and location is also found, but when driving in my car, and the Navigator is following with the GPS it freezes. Screen doesn’t react and also the hardware buttons doesn’t react. At this moment the phone is really warm. So did install Setcpu and underclocked the CPU. Tried again and the same phone freezes. This time the phone wasn’t so warm, seems the underclocked did his work good.
Tried many other applications/games and no problem at all. Example the game Asphalt 5 HD works fine and the phone doesn’t seems to get very warm. (CPU at normal speed again)
Someone having the same issues or a solution?
Sorry for my bad English

I have exactly the same problem with my Leo - I tried several Android ROMs - same result. Bute I also had freezes as WM6.5 was installed so I think it`s a hardware problem as other Leo`s seem to work fine with Google Maps Navigation. On Monday I will get my new Leo - After flashing I will post any news as soon as possible.
CU!

My English is poor, but too XDA worship. So come learn, support.

Thanks for the reply. I had no problems when Windows Mobile 6.5 was still installed on my HTC HD. Also did not found a solution yet.
What the meaning of the last reply is??

I've the same problem on my HD2 on Android Rafpgina 4.2 Rom
It freez by about 5/10 mn using Navigation
Trying other Radios = same problem
Could you tell me if the change of your HD2 resolved the problem ?
It should suggest a gps chipset problem

Yeap, still the same problem and I can't figure out why.
I've tried more than 10 different apps, but allways the same. After some time the phone freezes. I remove the battery, start the app and after a while, the same.
I tried working with battery only or with car charger only, still the same.
I removed and brought back all my apps with titanium backup, still the same.
I have a suspicion that when it stacks and after rebooting, if I leave it in peace (I mean don't do anything with the phone, just keep it without running any app), for some time (10-20 minutes), then it starts and keeps the gps app more time, than the time of the initial freezing. Maybe this is a symptom that could ring a bell to an experienced guy...
Anybody, any ideas?
I use Leo with nand froyo 2.2

I do not ues google navigation, support.

There is also this thread, by gunjahman, with the same subject (more or less) so we can combine powers.
Check it out

If you are using gps navigation software on sd card, try format micro sd card with FAT32 and DEFAULT ALLOCATION SIZE option, do not choose allocation size such as 32,64 or any other except DEFAULT.
Try it and GL.

@gunjahman,
Thanks for the URL, I will follow that thread also.
The software isn't installed at the SD card.

Then free up your phone memory as much as you can, move everything you can on your sd card which is formated with FAT32 and DEFAULT ALLOCATION SIZE.

That was the exact issue I had with my phone.
iGO and Aura worked fine in the beginning but Google Navigation would freeze the phone at random times. Only solution was to pull out the batt.
Mine became worse when iGO and Aura also started loosing GPS lock and the only way to get it working again was to reboot.
In the end I sent my phone back to warranty and they replaced 'a board'
Working fine now.

Sorry, that I didn't replied earlyer. To busy with work and other things. I delivered the HD2 to Vodafone so they can hand over to repair, get a suggestion back, because they told this isn't within the guarantee. The printboard need to be replaced. I think they mention the motherboard and they told the battery gets to hot.(total costs €285,-) This isn't what my complain was, so answerred back that the phone freezes when enable the GPS module and not the battery gets to hot. Told the battery gets warm, because the phone get warm. Waiting now for an answer back.

Better late, then nothing. This is solved for me, found the same phone on marketplace a few months ago.
Thanks for helping me.

GPS Issues on Desire HD - Considerations, tools and tips

I'd like to make a unique single thread with all the issues related to gps on DHD and the procedures/tips to make it work better.
MY EXPERIENCE
I was ready to go to dinner to my girlfriend's uncle (50km far away). I bought my DHD two days before. Ok, let's try gps. Google navigator. Started driving and my phone didn't get a lock. After five minutes of driving, i needed some help from navigator. Nope, still no gps lock. I stopped the car, got out with DHD in hand and lock again in two minutes with the sky in sight. No problem until destination. At the end of the dinner, on the road again. For the first 3 minutes, gps lock. Then lock lost, gps icon blinking and nothing. Tried to reload the phone. Fast boot first time and complete reboot the second time. I didn't stop the car this time, tried while driving (my girlfriend handled telephone while i was driving ).
It took 45 minutes to get lock again. Thanks god, i learned the route on the journey there.
The same thing happened again three times in the next days.
I thought that some software installed corrupted my phone.....(sorry, i was used to the windows mobile whims!!!!).
Hard resetted, but the problem was always there. Without logic, sometimes i had gps lock, sometimes not. Sometimes my DHD was keeping the lock until destination, other times gps lock was lost while moving.
GENERAL CONSIDERATIONS
Not all the people complaints about gps on DHD. I don't know why but there are many people who have problems using it. I think that, except for the faulty devices with defective gps chip, the behaviour is the same for all devices. Only the people perception about the performances of gps are different, and their behaviours of use. I had different expectations about gps. I was used to start driving without gps lock, my HtcHD would have always found lock in one minute anyway. Even if moving, even if many clouds or raining.
People who arrived to Android coming from Windows Mobile do experience a general lack of speed in locking gps position and a very different way about gps is handled by the OS.
My DesireHD hardly locks gps where my previous HtcHD locked gps in few seconds.
The same difficulties I have now with DesireHD, I had them too when I installed Android on my HtcHD. But I thought it was the unstable Android SD ROM's fault.
Another issue is the speed of hot start: DHD seem to have a very very short term memory in fact of gps. Hot start is really hot only if you reconnect within short time.
My HtcHD was able to reconnect in few seconds even if hours passed from the previous lock, if not moved.
My new DHD needs more time to lock, even if the previous lock was 30 minutes before. It happens to take 45 seconds or more to lock again if the sky is not completely in sight.
Even if I get lock with GPS Status, shutdown the program and I reopen it few seconds after, gps lock is not immediate. It takes almost ten seconds to lock.
I think I have to forget the Winmo performances in fact of gps, on Android.
(I think it's the only thing i'm gonna be missing, anyway......)
I think i'll have to wait for the lock before start driving from now.
ISSUES EXPERIENCED BY USERS
- DHD locks gps but when moving it loses the lock and it stays for minutes (from 10 to 60) looking for it again. -
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock. Phone never ever locked gps, whether indoor or outdoor, with the whole sky in sight.
Try resetting AGPS data and let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
If you never ever succeed to get a lock, you should consider to have a faulty chip on your device. I think it's better to contact HTC Repair service.
- DHD behaves with no logic. Sometimes it finds a lock in seconds, sometimes it takes ages to find a lock.
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock if any data connection is available.
Try resetting AGPS data e let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
TIPS
Do all of these steps. And, except for the first, try to do them all the times you use gps. And evaluate the improvements, if there are.
One time procedure:
- Force the phone to lock gps without any data connection and check APN type (see below for the link to step-by-step procedure).
It is important to put the phone outdoor on a stable and straight surface in order to get a strong lock, with a complete view of the sky.
My advice is to empty a-gps data BEFORE doing this operation (this can be done with GPS Status - Menu => Tools => MAnage Agps state => Empty data - The program is free and doesn't need root permissions)
Before every use of gps:
- Use FasterFix (needs root permissions) to change NTP server zone. The system/etc/gps.conf file contains parameters for NTP server and AGPS data. In mine i find that the ntp server used is located in northamerica. I live in Rome so I use Fasterfix to change it, forcing to use european ntp server. I don't know why but Android changes by itself this file, putting again north america server, so i have to change it more than once in a day to keep it using european server.
NOTE: Fasterfix gives back an error the first time you open it, choose the seerver and try to apply it. Only the second or the third attempt, it returns an ok result. Don't mind error. Don't worry about it. Even if returned error, it did its job anyway.
- Synch Device clock with atomic time. I use ClockSynch (needs root permissions), but every program capable of doing the same thing can be used. This is intended to help device in calculating your position. More accurate time means less corrections by the software, faster position calculating and a more accurate position.
- Let the phone get a strong lock BEFORE starting to move with your car. A couple of minutes before, you should let your phone on a stable surface, with sky in sight. Outdoor, obviously. Better if outside the car.
This thing could seem stupid, i know. But let your DHD get the lock in a place where it has a good view to the satellites. Let it acquire precision (you can see it in the left middle part of the screen, using GPS Status). Start moving only when precision has reached a minimum value (expressed in meters/feets - lower value, more accurate). You will see that gps lock will be more and more stable than before.
- Use a task killer program to kill all the processes which may use gps. I noticed that if one or more program able to use gps have been left opened in background, sometimes, without logic, something goes wrong and Gps receiver is no longer reachable by software.
In this situation if I open GPS Status, I see gps icon blinking, but in fact no satellites are seen by the program. I mean that on the screen is not shown 0/3 or 0/5 satellites. On the screen i see nothing about the number of sats, neither 0/0, empty. And in some situations this thing cannot be true (i.e. if i am completely outdoor with a perfect sky view).

Just 1 possible solution for you, have you tried to upgrade your radio? This may sometimes help solve GPS problems.
Sent from my Desire HD using XDA App

No, I didn't upgrade my radio.
I'd like to do it but i'm very hesitant to mess around with my phone like this.
P.S. Let me know if you had some improvements.

Updated radio can make a MASSIVE difference. One of the best things you can do to your phone if you're having any kind of GPS / 3G / Wifi issues.
Go to:
Menu > Settings > About Phone > Software Info
Where it says Baseband Version, this is your radio version.

For me the most annoything that happens with GPS is that when playing a music and using at the same time an offline map gps program, when a voice or some ding dong sound happens, the music played stops and resumes after those gps sounds ends...
I think this is due to Android sys... even WinMobile it's better on this...

Thanks for the tips. My GPS is locking on very quickly now and even inside buildings. I used clocksync + GPS status + Fasterfix. Fixing to around 8 - 9 satellites indoors and 12/12 outdoors.

Done.
Great.
It Works!!!!
initially it would take me a good minute or two to acquire a precise location INDOORS, now it does it in 10-15 secs!!!!!!
i was already using GPS Status, this is with FasterFix.
Thanks.

so strange I never had problem with GPS, always fixes in less than 10 second and never loses as well.
I use iGO and it never let me down.

I had problem with gps-lock from the beginning.
Tried the link above "gps-lock without dataconnection"
Now it locks within seconds
Sent from my Desire HD using XDA App

Personally, I've had no problem with gps for apps such as Google navigation where the screen stays on.
It's a different story, however, for apps like cardio trainer where the phone loses gps lock when the screen is off. I understand this is a known issue with Android 2.2 and has been fixed for 2.3+. I don't know if anyone else has problems with this.

but mine desire didnt work? first when take out the sim card ,reset and download data ..it work like charm..lock around 10 sec..then put sim card back it took age cant find satelite to lock..
anyone know what wrong?

On my DHD, indoors, GPS sucks badly.. apps such as "aroundme" its pretty useless, just hangs finding a signal. but outdoors when I use navigation, etc it works okay. I dont use GPS that much anyway, so cant complain. It is a tad annoying when your indoors and cant find stuff though.

I've had really big problems with my GPS.
Could not get a lock so I rooted my phone and upgraded the radio. Changed the gps.conf file and reset A-GPS settings and tried GPS without a dataconnection. None of the suggested things above did work, so I downgraded the radio to stock and unrooted my phone and sent it to a repair center.
Hopefully they will fix it.
I have a Hero (root) and a Desire (stock) and they get a lock on within seconds and works flawless even indoors.
I guess HTC has a lot of faulty GPS modules in their Desire HD mobiles, but not all are using GPS so therefore we only hear about some of the problems.

Trying the Nexus one fix as in the first post, after taking SIM out, I do not get any GPS signals on GPS Status, if I put SIM back in I get fixes but GPS unusable as it keeps losing connection whilst in journey. The steps I have taken so far are as follows:
* Take your SIM out of the Nexus One
* Power on the device
* Turn WiFi on
* Turn GPS on
* Open application: GPS Status (ver 3.4)
* Go into its Settings menu
* Click on GPS and Sensors
* Click Manage A-GPS state
* Click Reset
* Click Manage A-GPS state again
* Click Download [You'll see a message telling you that a data connection is needed, ignore it]
* Now put your phone on a stable, straight surface in order to enable the phone to get a lock, within GPS Status. This time, you’ll see your phone get the lock way faster than before.
Any help will be appreciated.

quoting my self...
There's some developments about this issue...
Or one use the nice HTC Gps Software (at least the version that cames with gingerbread) or use the iGO Amigo.
I tried the iGO Amigo and I finally can listen to music at same time when the voice from iGo speaks!!! There's no interruptions at all like on the majority of GPS softwares that I tried on my DHD (don't know how it works on another devices)
I think that this issue is something that is only developers fault cause initially I thought it was due android design, maybe it was only possible to play something only from one app at a time. (ie. not play two things from two different apps simultaneous) but I figure that after all that is possible.
Bad developers!!!!

GPS Problems: finally the solution
Hi all,
Here I want to tell my experience with HD Desire GPS to help all those who were (like me) desperate.
The way to solve exists ! Read to the end to know how.
I bought my HD Desire in January 2011 (from Euronics in Rome - Italy) and after one week of use the problems began with the GPS.
It did not fix more ... but above all there were more than 1 or 2 visible satellites ... even in open sky, in good conditions, even outside for 30 minutes.
The phone was obviously still immaculate (without root and with the original ROM and RADIO) then I went back to the shop where I bought ... and using GPS-Status the seller has found that actually did not work.
Very kindly he changed my on the flight the phone ... I installed GPS-Status on the new phone just replaced and now everything works fine (fix in less than 10sec and 7 / 8 satellites visible).
I came at home and for 2/3 days it worked wonders but soon it began again with the same GPS problems.
No more fix and at maximum 2/3 satellites visible.
Building on the fact that the phone had been replaced and ... GPS Status actually had made a fix in less than 10 seconds ... (When I had replaced) ... I said, Sure ... is certainly a software problem and not an hardware one ... because the phone is a new one.
So I did a factory reset ... reset all settings as the original ... and retried. Nothing.
The GPS was dead for the second time in two weeks.
Then, I began a careful search on various forums (both Italian and international).
I've tried everything ... really everything ... but nothing. It does not work !
Tried GPS-Status (A-GPS Reset, Download), then fasterfix (it.pool.ntp.org) then I started to change ROM (root, S-Off and ENF S-Off), then I tried all possible Radio and RIL in all combinations. Sometimes happen that the fix was very fast and this gave me the illusion (temporary) of having finally found the solution. However, on time (sometimes even after a few minutes) the problem returns back!
I also tried to clean the contacts of the GPS as shown in this video on youTube(h**p:/*w*wdotyoutubedotcom/watch?v=7qm_z65LA8k).
At the end ... after 4 months of trying all... I sent back in warranty the phone to the HTC service (S-ON and leave to unroot because it was under warranty).
After 10 days of impatient waiting, HTC gave me back the phone and say that the GPS was faulty and had been replaced.
I redid a restore using Titanium Backup Pro ... restoring back all in the exact same conditions I had when the GPS was not working.
Now everything works wonderfully !!!
Im using the original ROM (RUU 2.36.405.8), original Radio (12.54.60.25U_26.09.04.11_M2) and the original Kernel (2.6.35.10-g0956377).
Fix in 10/20 sec (everytime), with at least 7 / 8 satellites (tested for several days now).
Moral of the story ... There are lots of HTC Desire HD phones (probably the first stock) that today are still in the form of stocks and inventories in some shopping malls / shops with the GPS module that is broken !!! (it works for a few days and then no longer works).
The only way is to send back your phone in warranty and ensure that GPS module is replaced (having first restored with all unroot and S-OFF as otherwise the warranty does not apply).
Believe me ... if you have tried everything ... this is the only way!
Now I'm an happy HTC Desire HD owner (with Gingerbread) with a GPS which is a splinter.
Im currently using Navigator, Google Maps, CoPilot and everything works great !
I hope this post may help and comfort those who are desperate and can not run the GPS on the Desire HD.
Greetings to all.
Andrea.

cannot connect to gps

i picked up a focus 1.3 for my wife for a replacement because she broke her phone. i cannot get the gps to work. would not work on 7720, i forced update to 8107, still would not work. just installed the clean rom 2.0 (8773) and still will not work with maps, nokia drive or garmin street pilot.
i can't figure out why it's not working, but my wife really needs gps. are there any fixes?

Try GPSInfo. I used to recommend GPS App (has Bing location), but now that is paid. GPSInfo gives you info about:
- GPS State
- Mode
- Accuracy (H/V)
- Course
If GPS State doesn't state "GPS Started", you have a HW problem.

it states started, but it's only using a-gps for location. which will not allow me to use on any navigation apps.

It should say "Full GPS mode, satellites data" when fully working.
Make sure you turn off ALL data connections, you waited at least 10 minutes under a clouded sky and you are not in (or very near to a building) You do need to see the sky to get satellites.
If after 10-15 minutes under a clear sky you still see "A-GPS Mode" your hw may be affected
LE: A possible cause I can think of would be wrong drivers/firmware issue. As a possible way to fix that you can try flashing a stock rom or a custom rom. Normally I caution people away from custom roms as I've seen several "stuck at boot/samsung logo" through out the forum, all tied to custom roms. A stock rom is the firmware meant for your phone and even if you start from scratch at least you know it's the right thing for your phone. If you want to try that, see the post in my signature.

even with the 7720 update through zune, i had this issue.
i did revert back to stock, turn location off, then did the updates. all the way to 8773, and the gps would lock after a few minutes outside.
however, while driving, with the garmin app, all of a sudden my "vehicle" went shooting about a 100 yards off the road, then it never was right the rest of the trip.
so the gps seems to just be working intermittently, or whenever it feels like it..

Considering 8773 (Tango) was not yet officially released/tested for Focus, I need to ask: is your phone a Focus (i917)? If so, it might explain some if the issues you're having. I would suggest staying with stock 8107 for the moment, but ultimately it is your choice. Also, make sure the phone's drivers are updated properly, 'cause if they don't, what you're going to get is issues...

like i said though, it was the same deal from 7720 on up with the updates from zune. i'm going to try to to revert back to 7720 and install the samsung drivers for mango cab that i have.

GPS
Had similar GPS problems on Focus 1.3, tried different ROMs, etc. Only decent fixes I've found are pulling the battery out for ~30 minutes and turning on find my phone in settings. Not sure why battery thing works, but have seen the same suggestion for a lot of other phones.
Problem is my fixes have been temporary; GPS works for a while, then gets flaky again in a few days, even after reflashing.
Other Samsung phones that came out around the same time as orig Focus w/ similar HW specs had people tearing their hair out with GPS problems (Captivate, Galaxy S). Unfortunately, general consensus in Captivate forum seems to be problem is 75% hardware. Those guys tried endless SW / OS tweaks; some helped a little. Unlocked mine to try to find similar tweaks, but haven't solved the problem yet

[Q] GPS Problem - Not Gingerbread

I have a gps problem with my hd2 t-mobile but it doesn't have anything to do with gingerbread. Specifically, if the phone get a little warm, gps stops responding. I don't get any errors like not finding the gps but no satellites. Problem exists in NexusHD2 4.0.4 which I'm running from native sd and in windows mobile. If I reboot the phone and go straight to wm and run a gps test no satellites. If I shut down the phone and turn it on immediately no satellites. If I shutdown and let it cool down or force it to cool down (lay in on an Icepack) It works (until it warms up again) than nothing. If I cool it down without restarting (lay it on the icepack) it doesn't come back. I already suspect the worst but still asking.
In any case I've got a globalsat external bluetooth gps which is far more accurate than the internal gps. I was just hoping on avoiding using it in inconvinient situations. I currently have two hd2's one of which is a new t-mobile with overheating problem and the GPS problem and the other an older hd2 non t-mobile with the funny color patches on the screen and I don't think I'm going to go in the HTC direction again. Samsung seems to be looking good.
