Fujitsu Arrowsx F02E GPS error

[wkh7777]

I bought Fujitsu Arrowsx F02E phone last week. Great Japan phone for low price. It works great(Fingerprint sensor exelent :fingers-crossed. But,

1. When I turn on GPS using 3G network it restarting again and again(GPS work fine with Wifi)

2. Antutu benchmark shows lower score for processor and GPU (Compared with HTC one X(Both has Nvidia tegra 3)) HTC one x has 1.5quad but this phone has 1.7quad :laugh: . So, why lower score?

3. Asphault 7 not working also(Game opened its Menu is slow and game not started).

Please help me ASAP.

And Can someone please tell me where Can I find custom rom for this?

i have exactly the same problem with gps on this phone...
have you found some solution by now, perhaps?

To OP:


1.

GPS will crash the phone to restart is normal for ALL NTT Docomo NEXT series Smartphones. I have confirmed with my F-02E, F-06E, SH-06D and an even older NEC MEDIAS.

To use the GPS on these devices, you will have to turn on the Airplane mode to work if you are outside of Japan and is using a foreign SIM card. (GPS will work fine with 3G or 4G LTE Xi with a Docomo USIM in Japan)

*****(Though I have read somewhere that a non-Docomo 128kb MicroSIM might do the trick, but I do not have one to test)*****

Also do not expect the GPS to be as fast and accurate as the Galaxy S3/S4 as the F-02E does NOT support GLONASS.
The GPS receiver is optimized for Japan region only (maybe can change satellite list after root).
A-GPS for faster GPS lock is DISABLED without a Docomo SIM.


2.

The reason for the lower score is because of the lack of optimization, as well as all the BLOATWAREz Docomo has preloaded on the phone. To uninstall these Docomo software (useless outside of Japan), you have to r00t.

Fujitsu kind of failed with the F-02E. Even after the V17 update, Android 4.1.2 is really unstable on the phone. I had the OS crashed in several occasions in different apps and some games.

To get the best performance out of the F-02E, you have to flash a cooked ROM.

Though the stock OS is much faster and stable on the F-06E, though in synthetic benchmark, the F-06E still scored lower than my Galaxy S4 -i337m


3.

Asphalt 7 works fine for me on my F-02E. Also gameplay is rather smooth offscreen at 1080p.
Asphalt 8 works good too, but some occasional frame drops on complex maps.
Shadowgun and DeadTrigger both plays buttery smooth.

Epic Citadel Unreal 3 Benchmark, the F-02E at 1080p on Best Quality setting gets around 30fps - 40fps (Tegra 3 works better on 720p screens, and again lack of optimization from Fujitsu on the software side)




Hope this helps.
Cheers

you're great, man! thanx a lot for your answer -
but where can i find that cooked rom for f02-e?

You will have to find some clues on Japanese BBS boards (2ch etc **NSFW)
Development for this phone in Japan is gathering more people as the average retail no contract price of a brand new F-02E in Japan costs around $160-$180 since around May-June of 2013

You can also find active development in some Chinese forums

I use F-06E with 3G operator and have no problems with GPS, no reboots, navigation apps work good.
Also, I had F-02E, it could not find any satellites at all.

You might have a 128k MicroSIM card with your F-06E.

My 64k Rogers Wireless MicroSIM make both my F-02E and F-06E reset when GSM and/or HSPA is turned on (mobile data on/off does not matter), and GPS is on and searching for satellite for location.

***NOTE*** If the GPS is just on and not searching for any satellites, the phone will not reset.


Regarding your F-02E does not find any Satellites in Moscow (Your Location).

The F-02E will find a GPS lock eventually, but it may be unstable and take quite long time to lock. The main problem is because the GPS receiver chip in the F-02E does not support GLONASS, and the GPS locale list is configured in Japan region. So outside of Japan region, GPS will be flaky without rooting and updating the GPS locale conf.

The F-06E on the other hand does have GPS/aGPS and GLONASS support as part of the Qualcomm S600 platform SoC. GLONASS lock should not be a problem.

***NOTE*** The aGPS cellular assisted location service will not work without a Docomo USIM. Hence on phone with only GPS and no GLONASS, like the F-02E, initial lock from cold boot may take some time.

I am having the same issue with my F10D, GPS keeps trying to locate satellites. I'm considering rooting it to update the GPS Locale list but I need guidance on how to update such list. Any help will be much appreciated! Thanks.

Even if updating the GPS list, the performance is only bit improvement. The antenna/receiver used in these Fujitsu phones before the Snapdragon 600 ---- F-06E are not great to begin with

If you really want a faster phone GPS, then its time to find other phones

As for a flashable GPS locale config for other countries outside of Japan, it will be hard to find if it even exists

Thanks a lot for the explanation!
One more question - If I flash the phone and install a new ROM, do you think the GPS may work?

Thanks

Restarting problems. Need a solution. Please ...

Hello, I bought my unlocked F-02E mobile in Japan this summer and I brought it to Spain. I have disabled some docomo apps but the pone keeps restarting. I couldn't find the way to update or download the V17 firmware upgrade because I don't have any Docomo SIM in order to download it. I don't know if there's some cooked rom available to flash it and get a solution to avoid annoying restarting problems when calling or after calling or using 3G data ... (it happens randomly). I use GSM only here in Spain but when I call with data enabled it also reboots sometimes

Neither I don't know if buying a new 128K micro SIM could help to avoid rebooting issues.

I'll wait for your solution.

Thank you very much in advance.

Best Regards

I can understand your frustration and pain.. I have gone through the same for past few months. I had verified with 64k, 128k and 256k sims. None of them fixed the issue. It reboots with any kind of sim. so buying a 128k sim will not help. But, only sim I have not verified is 'LTE sim with 3g/2g support'. It might fix the issue.

However as a workaround, I have modified some android props to suit Indian network conditions and the phone is much stable with a 64k sim now ! Still there were two reboots in three days(found the cause, will fix it) and it never rebooted during call ! Earlier it used to reboot 5-6 times a day. It used to reboot during/after calls, when kept idle, when I am cooking, etc...

Fix is to disable LTE on this phone and set some 3g/2g parameters. Additionally you can set some default locale and gps config too.

Please do the following tweaks and let us know the result.

Steps: (search the forum for appropriate links)
1. root your phone and mount /system as read/write. (must)
2. Now disable LTE and configure 3g/2g parameters: Add the following lines to "/system/build.prop" file. (can directly copy paste the following at end of the file)

# system props for telephony modules
# Disable LTE/4G
ro.config.lte=false
# Set default network to be 3g/2g auto (wcdma preferred)
ro.telephony.default_network=0

# set hsdpa/hsupa categories
ro.ril.hep=0
# hsxpa=2 signifies hsdpa and hsupa. you can leave it as 2.
ro.ril.hsxpa=2
# gprsclass=12 is maximum value it can have. all modern networks should support this, else as a conservative setting try 10.
ro.ril.gprsclass=12
# hsdpa=8 and hsupa=6 signifies 7.2mbps dowenload/5.76mbps upload. If your network supports it, leave it as it is. else try 6/4 for these values
ro.ril.hsdpa.category=8
ro.ril.hsupa.category=6

# some signal strength, power tweaks
ro.ril.att.feature=1
ro.ril.disable.power.collapse=1
ro.ril.fast.dormancy.rule=1
ro.config.hw_fast_dormancy=1

# fixes connectivity issues, my phone used to loose network very often.
ro.ril.enable.dtm=0
ro.ril.enable.a53=0

# believed to be signal strength tweaks
ro.ril.enable.ncell.ind=1
ro.telephony.ril.v3=signalstrength,singlepdp,skipbrokendatacal

# better voice quality
ro.ril.enable.amr.wideband=1


3. Now set gps settings in build.prop. Add the following lines to "/system/build.prop" file. (can directly copy paste to the file)
# AGPS mode set
ro.ril.def.agps.mode=2
ro.ril.def.agps.feature=1

4. Now change locale settings. (So that when you do a factory reset, it does not show you japanese text) Find out following props and change it. (in "/system/build.prop" )
ro.product.locale.language=en
ro.product.locale.region=US

5. Now lets fix gps settings: (replace contents of "/system/etc/gps.conf" with the following). you should set NTP_SERVERS for your region. rest of the things should be fine for your region.

NTP_SERVER=asia.pool.ntp.org
NTP_SERVER=0.asia.pool.ntp.org
NTP_SERVER=1.asia.pool.ntp.org
NTP_SERVER=2.asia.pool.ntp.org
NTP_SERVER=3.asia.pool.ntp.org
NTP_SERVER=0.vn.pool.ntp.org
NTP_SERVER=1.asia.pool.ntp.org
NTP_SERVER=0.asia.pool.ntp.org

XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin

# Accuracy threshold for intermediate positions

# Report supl ref location as position, 1=enable, 0=disable

# TRUE for "User Plane", FALSE for "Control Plane"
DEFAULT_USER_PLANE=TRUE



6. Change some parameters in "/system/etc/gps/config/pathconfigfile.txt". Replace the file with following content.

#
# Config file
GPSC_CONFIG_FILE /system/etc/gps/config/GPSCConfigFile.cfg

# Patch file
PATCH_FILE /system/etc/gps/patch/patch-X.0.ce

#Logger NVM setting, when LOGGER_CONTROL = 2, else ignored
LOGGER_NVM_FILE /cache/gps/logs/

#Logger - maximum lines in log per file in NVM
MAX_LOG_LINES 100000

#Logger - maximum log files in NVM
MAX_NVM_FILES 10

#To/From Sensor Control
#0->Dont write:

#Sensor log NVM setting

#Session log Control
#0->Dont write
#1->Write to NVM
SESSION_LOG_CONTROL 0

#Session log NVM setting
SESSION_LOG_NVM_PATH /cache/gps/logs/


6. Now, DO A FACTORY RESET. AND PLS DO NOT DISABLE ANY DOCOMO APPS. Use the phone for couple of days and if it's stable, start disabling docomo apps.
Please do let me know if it helped.

Note: still you might see a reboot, as I had seen two reboots in last three days. Found the cause, fixed it and device is under test again Let's hope no more reboots on this device.

PS: I hate this device so much, if it reboots again I will throw it out of the window.
How can some one release a device without proper verification ? a docomo user might face same issues while in international roaming !

 

[diamoncito]

Thank you

Thank you very much!. I will try these steps you explain but I guess I'm going to buy another mobile because it's not very useful to have a phone which cannot get Android updates and cannot use 3G data without rebooting.

I'm planning to buy a Moto G which is made by Google and they say that Android 4.4 update is sure at the beginning of 2014. And it's cheap and has good specifications

 

[biswaranjan]

I also had problems of not being able to use 3g data without rebooting. These steps would solve it too don't disable any DoCoMo apps.

But software update is a real prob..

I quit. No further wasting of time n energy.

Rebooted many times today, reboot happens while searching for network.

Am selling the phone now. Will go for Google device.

New Software Update V19R50D?

Hello,

I've seen there's a new nttdocomo software update compilation (V19R50D) and I've read somewhere this update solves rebooting (I read it on a japanese page translated thanks to Microsoft Bing Translator ).

Do you know if there's any way to update software without nttdocomo SIM and outside of Japan?. I've searched but I haven't find any way :crying:

Anyway, I'll buy a new Google device too because my F-02E, although there's a nice device with great specs, it's unuseful if you cannot call without restarting or surfe the web with at least 3G data.

Thanks!
