Time and Date keep resetting. - T-Mobile LG G2x

So, not rom specific, but the time and date keep resetting on the G2x after a reboot. I gave it to my fiancee as a wifi toy, but it's starting to get frustrating as it starts to create issues with certificate errors and the like as well. Doesn't matter whether it is set to auto or manual time/date set either. Is there some kind of internal battery / capacitator that has seen some better days that is causing this? Thanks for any help / suggestions in advance.

Is the phone still on an account. Usually the time and date is set by the towers when connected.

Nope. No longer use the phone I gave up on it because it had too many signal issues that were phone related - not service related. That's why it is a wifi toy now. However, that shouldn't matter because the time/date didn't have this trouble till the past month or 2 and other android devices like tablets, which generally don't have service, don't have this trouble either.

[Q] Syncronising time

Is there a way to syncronise the time on my HTC HD7. I notice it regularly loses a couple of minutes each day.

In Settings, Date & Time, make sure you've got "Set Automatically" switched on.
This should keep your phone's clock in sync with Internet Time servers.
If it doesn't work, then there's either a bug, or the time servers can't be contacted for some reason.
But AFAIK there is no other way to sync the time.
Thanks for the response. It is already set that way. perhaps an app will appear in due course.

I very much doubt it! For a start, as I understand it, apps can read the system time on the phone but they do not have the privilege to change it.
I may be wrong on that, but then you've got the fact that WP7 already does time synchronization, even if it doesn't seem to be working for you at the moment.
Looks like I shall just have to correct it manually periodically.
Still like the phone and wp 7 even with a few foibles.
Maybe a Microsoft update can fix it.. does Microsoft even know that their clock is faulty and needs manually fixing?
I don't have such a switch in date and time...
there is just a switch to make the time show 12 or 24 hour...
a selection field for time zone, selection field for time, selection field for date
No automatic update switch.
I have a HTC mozart, and I also noticed a slight delay (if I don't connect to the computer, but if I connect to computer then it seems OK...). BTW shouldn't work this automatic update also through Wlan?!?

Gold_C DFT Error reporting

Hey all;
I saw some DFT clutter on some other ROM threads. It was suggested to make a new thread. I have permission from Mwang to make an error reporting thread so... here it is. Also... for all those who don't have DFT's ROM for the Gold_C you can PM Mwang for download instructions. I am working on getting permission to put links and dl instructions on this thread as well so look for updates. Thank you.
Has a newer version of the DFT rom for GOLD_C been released? One major bug is that wifi mac address changes with every reboot.
Still a badass rom!

-Some programs you cant see well unless you have the theme on dark, I think I read somewhere that it was a common bug in his wp7 roms.
-Maybe not a bug but an issue (If Mwang used sprints rom as a base) the sms bug that limits you to 160 characters per text is present like in the sprint rom
It is soo much better than the the official sprint rom tho
I have been having data connection issues. I will have full service and my data connection on and apps will say I have no connection. I have tried to update my network connection and prl and this continues to be an issue. For whatever reason I can usually go into internet explorer and go to a website and that will work and then return to an app I was having issues with and then the connection works. Seems really strange to me. Anybody else else having similar problems? Any solutions out there?

I have had something similar, although I've found that the internet is working still but incredibly slow, even when connected to Wi-fi, it seems like even with Wi-fi on, the phone prefers to use the network connection. I've found that turning on airplane mode and then using Wi-fi makes the internet work fine and quick, but with both on it seems to go much slower (but not always). Other than that it seems to be working fine
HTC Arrive ROM ???/Issues
I love this ROM, much better then stock but when I am on a call and the computer voice says" press 1 for xxx press 2 for yyy" I press the buttons but the system doesn;t respond like I didn't press anything at all. Also the Speaker volume seems to be 1/2 as loud. Last but not least is there a GPS program I can d/l? I used navigator all the time but since this ROM doesn't come with it I don't know what to use.

you can search for "TeleNav" in the market, "Waze" in the Bazaar, or you can search online for "Nokia Drive" xap where you would have to deploy from your computer. I'm not going to link to the Nokia Drive as I don't know how legal it is to do so.

If you didn't yet, try a hard reset. That solved all my issues. I should have remembered that from the TP2 days...
I too am having issues with the internet speeds. My phone is constantly going into 1x. i can have full bars and it still goes 1x. even with Wifi on the phone still tries to use the cellular data and if that says 1x well its slow as hell. I have re flashed the rom and also done hard resets a few times, it didn't fix it for me, i mean it works great for a little while than the same problems persist.
According to what people are saying in ansar rom, it has the same problem with the connectivity. Hopefully there will be an update to fix this.
Another bug is that picture mail fails 95% of the time. i found that if you switch wifi off and than do a reset it usually works for a few times.
I wonder if we can fix our DATA issue if we input the APN settings into the rom. I used to run droid on my tp2 and we had to configure the APN for things to work as expected. I have searched around google and such and cannot find any working APN settings. Does anyone know of any that will work or have tried it?
Hey guys first off happy Easter to everyone! Secondly, I think I might have found a workaround for the WiFi cutting out on DFT sprint rom for the arrive. If you are on this rom and you have sprint well than you probably noticed the phone always going into 1x and than the WiFi taking forever to load. I had seen a post about shutting off cellular data and that was suppose to help. Well, I tried that and it worked for a little bit but than it stopped.
What I found is that if you change the network setting from automatic to home only that the WiFi no longer cuts out. The phone still says 1x but my WiFi hasn't cut one time and beforehand it was constantly working slow and or not working at all. Also, every picture mail that I have tried to send has went through without a single fail which it was a real pain in the butt to get one to send before. I haven't done too much testing as to whether the phone works better when not in WiFi but since I'm always in the office or at home, I'm always connected. But at least now it's working much much better!
Reg Settings for EVDO (3g is slow)
I have, like others, had similar issues. Also, after updating to the rom i noticed that the 3G speeds have dropped significantly (WIFI off).
I am clocking in at ~300k as opposed to 1.2Mb before even though the phone has 5 bars and EV.
I am not sure if this will provide any insight, or if I am even on the right track/know what i am talkin about, but if i browse the registry to
"HKLM\Comm\Cellular\DataSpeed"
There are settings for only 1xEVDO. Is this right?
What about EVDO rev A?
Thanks in advance for any input!

[Q] Data Connection Time-outs

I've been having data connection issues for as long as I've had an activated Straight Talk SIM in the phone (about a week). Here's what's happening:
When I open an app or program that needs an active data connection, more often than not, data takes a while to start flowing. Often more than long enough for my screen to time-out before it connects. I have moderate signal strength, generally 2-3 bars, and the little H+ icon is there, so I'm assuming it's not a signal issue. Once data actually kicks in, it generally works fine for whatever time I'm actively using it. However, once i stop using it, and let the phone go back to sleep, it's a crap-shoot as to whether or not it'll connect quickly next time I need it to.
It doesn't seem to be a ROM-specific occurance, although it did seem a bit less likely to time-out when running stock Froyo. I've tried several different costom ROMs, a handful of different modems, and it never seems to make any real difference. I've also tried slight variations in the APN settings, to no apparent avail. Toggling airplane mode and/or rebooting don't seem to have any definite effect either. Sometimes data will connect quickly after a toggle/reboot, sometimes it makes no difference. It's like the phone just doesn't seem to 'know' that it's supposed to be transferring data.
Im having the same issue.My first month with ST was great really fast of course I went well over 2 GB so it slowed me down towards the end of the first month.Well I paid my next bill and still slow.They seem to be clueless when I call them oh your using an Infuse well I ordered the correct sim from there site they still clueless.Ive have tried about every rom out there just to see whats up and still the same issue.Hopefully someone here has the fix.
Im having the same issue nothin seems to work.

Since it's a frustrating exercise in futility to actually call and hope to get one of their script-reading robots that can speak some semblance of comprehensible English, I emailed them on their FB support page and started a claim ticket. Got the usual runaround about removing the SIM card and battery, do a hard reset, clear cache and cookies from browser, blah blah blah. It's kinda funny how I linked the CS rep to that thread on HoFo, and she's still not acknowledging that there's any type of widespread issue. SSDD with Straight Talk.
I just registered over on HoFo and was looking around their Straight Talk forum. I think someone may have found the answer to some of our data connectivity woes. It may be as simple as having to make a DNS change to compensate for an overly-crowded network. I downloaded DNS Changer from the Play Store, and changed my DNS settings to OpenDNS. It's a bit too early to tell if it's just random coincidence, or a real fix, but I AM getting much better connectivity so far. For some reason, it seems to work a little better if you actually use the ST proxy in your APN settings.

[Q] GPS not locking with demo video

I have a new OnePlus One which I updated to 44S. The GPS will not lock on signal reliably since I received it.
Neither Google Maps and the GPS Status tool cannot lock onto to GPS or it can take up to ten minutes for a GPS lock or it will never lock. I have tried High Accuracy and Device Only Location settings, also updated Google Maps, and applied all stock OnePlusOne updates. Indoors, I can lock onto perhaps 0-1 satellites and outdoors about 2-5. Eventually, I can lock up to 11-12 if I let it sit for a while outside. GPS signal is always lost immediately while in High Accuracy mode after I start moving the vehicle.
I have emailed OnePlus support and got a reply back the next day asking me to create a video. Therefore, I created a video which is linked below on Youtube which shows what it does in Device Only mode.
youtube.com slash watch?v=kDcLk_IuKQ4
Sorry for the URL, I'm a new user here. My question is what can I expect from OnePlus support on this issue and does anyone else have this problem? Today I got an answer to my last reply with the video that I should just do a factory reset and update to 44S from a different tech, so it's not going too well now and I don't think they really try to resolve anything.
I have read lots of threads on the Internet regarding running various fix apps (such as Faster GPS) which means I need to root it but I saw limited success in those posts (I have not rooted yet). I personally think it's a hardware problem since GPS Status cannot lock onto anything unless I give it a lot of time and clear blue sky.
I apologize if this is a repeat post or I committed any other newbie offesnes, but I could not determine a real solution to this problem. Should I keep pursuing an exchange or refund or spend hours more rooting and dorking around with gps.conf settings?
Thanks!
Usually I leave my GPS turned off and when I read your post I went ahead and turned it on and set it for 'Device Only' and experienced the issue. rebooted the phone with the GPS turned on and now I get an almost instantaneous locking.
not sure if you leave your GPS off like me or if you have it on all the time but If it was off when you started the phone try turning it on and reboot the phone and see if you'll get better results.

I have done the reboots. Does not make a difference in getting a lock or not. The GPS has to be left ON for a while to find the necessary number of satellites needed to lock.
Same issue
Did you get a solution from one plus? I have the exact same issue. I use my GPS for driving 3 or 4 times per day since the 44s update I have had 2 GPS locks which I believe is a problem.
Hopefully the upcoming update fixes all!!

CM11 M7 Wifi dead? here's a potential fix

OK, so I know M7 isn't the latest CM build, but it's the latest one without issues with GPS, so that's what I'm on since I use GPS a lot.
So last week I replaced my home router. This of course means reconfiguring all the wifi devices around the house, including my wifi thermostat. The unique thing about the thermostat is that to configure it, you connect a laptop/phone/tablet to the thermostat's ad-hoc wifi network, tell it which infrastructure ssid to connect to, verify a pin from the thermostat's screen (so nobody can hijack your t-stat from outside the house), and that's it.
thing is, when you use Cyanogenmod (at least on the relay) to connect to an adhoc network, it breaks wifi. what happens is you can't connect to any other wifi networks, and can't even scan to see available networks till you reboot. sometimes it doesn't work even after a reboot. strangely, the tethering/hotspot still works fine. you just can't connect the phone to a hotspot whether it's at home or work or anywhere.
i'd been having other issues and general slowness with the phone, so i decided to backup a few apps with TiBu and do a factory reset. that worked... till i tried connecting to the thermostat again, and it broke wifi completely this time.
solution? go to /data/misc/wifi/ and rename wpa_supplicant.conf to wpa_supplicant.conf.old (or whatever, as long as it's a different name) and reboot. the system will automatically create a new conf file. boom - wifi fixed.
obviously this requires root, but that's not an issue in CM. I doubt it matters, but i used ES file explorer since it's got a good root filesystem browser and mounting / or system as RW is a simple matter of a checkbox in the settings.
when i compared the newly created wpa_supplicant.conf with the one i'd renamed (.old) the only real difference i could see was the saved networks at the bottom. so you might be able to get away with simply deleting the offending network={ blah blah } section instead of completely renaming the conf file. the advantage here would be if you have a bunch of saved networks that you don't want to get rid of, it will keep those saved networks. the conf file is a plaintext file so it's easy enough to understand what you're looking at, and modify appropriately.
MODS: I apologize if this is in the wrong forum. I figured since it probably only applies to CM, I should post it in the dev forum rather than the general one. If it needs to be moved, I don't be offended.

As does FatToad. However, I do know that the privacy bit in the GPS can be flipped with the drivers we're using in FT. There's an old thread with a post from nard about how to fix that.

Do you understand more about this "privacy bit", what call in the API flips it, or can give me any other pointers about it? The poster previous to you indicates that GPS works with M7. I thought I had it working with M8, but can't really guarantee that, any more. The post from nard was quite an onerous process, including what looked like reflashing the baseband.
It seems to me that if we really understood this problem, the fix would be quite simple, and could be done by a root-access app. I've done more digging, and see that it seems to be common to many models of Samsung Galaxy phones, and some of the fixes involve doing potentially horrible things to the NVRAM. (like clearing it completely - what could possibly go wrong?)
It seems that the GPS is done in the baseband processor, along with the other radio stuff, but so far I haven't been able to find it. The transceiver chip is just a transceiver, no baseband processor. It looks like the baseband processor might be on the Snapdragon main processor chip, though they don't enumerate it well. In addition they mention a "gpsOne engine" without describing exactly what it is.
I'm still relatively ignorant about Android, a year after getting one. (not enough time) I'm better versed on hardware, but this problem seems to be in the cracks between.
Come to think of it, a simple question... Is there documentation on the communications between Android and the baseband processor?

I just took my wife's phone outside and tested it. GPS works on M8 from last summer, as does wifi. AFAIK the only thing that doesn't work on M8 is the video camera. (Stills on the camera work.)
This was an older phone than mine, purchased after mine. With mine I didn't need the radio or bootloader updates, my wife's did. I bought the phone for her, used it briefly with my PureTalkUSA SIM card to make sure it was really unlocked. Then I put CM11 on it.

no idea how old mine actually is; i bought it "like new" from a tmobile reseller here in town and i actually use tmobile for service.
right now i'm on fattoad and once i stepped down my paranoia (i turned on privacy guard for everything including all system apps. hint: don't do that ) it seems good so far. nova launcher has an issue with flickering or disappearing icons, and everything is huge (i need to adjust the dpi) but so far no issues with gps or wifi (though i havent needed to connect to an adhoc network yet).
Do be careful with Privacy Guard. I didn't mention, but although Privacy Guard out of the box tends to make it so that most system apps are unable to be tuned, TeamApexQ likes the option of being able to tune everything in that regard, so we removed the safeguard. (For example, when PG was first ported to CM12, you could tune the settings of the 'Settings' app. Then at our next internal testing build, it was suddenly coming up empty, because CM made a change to exclude tuning for it. We restored full capability because we liked it. But that does mean you can more easily 'shoot yourself in the foot'.

I've recently begun to wonder if Privacy Guard might be partially responsible for reduced battery life. I'm under the impression that it lies to apps, providing false information when they have insufficient authority for the real information. Some of those permissions in Privacy Guard are to turn radios on and off. If an app thinks it's turned a radio on, and is trying to communicate based on faked (Really, it's going to look like a failure, at this point.) returns, it may spend more time continuing to try instead of just staying asleep. My battery life comes an goes, but I've noticed that on a "bad day" there are quite a few wakeups in the middle of nowhen, when the phone was sitting there in airplane mode with all radios off.
Of course I may be all wet on this - radio control may be one area where it can say, "You're in Airplane Mode, no program can turn the radio on."
good theory, and like you said, it depends on the app and how pg implements each block.
personally i'm having great battery life in L. i have a 5000mah battery, but usually by this point in the day i'm at about 60%. right now i'm still at 83%. i like how it projects your estimated remaining battery time. first time i looked at the battery chart, i lol'd - it was projecting 4.5 days before it died. i can probably get 2 no sweat even with regular usage, but i'd have to turn off sync and really cut back to make it 4 days.
I've had very good results with some simple rules with Privacy Guard. Generally the only thing I've turned off is the ability for Google Play Services and the Google App (Google Now) to wake up my device and to keep it awake. With those turned off, my battery life has gotten to be pretty damned nice... Though it makes Google Play Services FC once maybe every 24 hours. It restarts just fine, no harm no foul.
My battery life seems to be "bimodal". It either barely makes it 24 hours - basically needs recharging every night, or it lasts on the order of three or four days on a charge.
It seems to be somehow wifi-related, if I were guessing, and in an odd way. If wifi is largely off, but occasionally on, the battery life seems shorter. After wifi has been left off for "a while" (quantity not yet determined) it seems to go into long-battery-life mode. If I keep wifi largely on, and occasionally off (basically between known/trusted wifi places) the battery life comes out somewhere in between, consistent with wifi itself taking some power.
It's been really tough to detect any sort of pattern, but this is the best I've been able to come up with so far. I haven't done rigorous testing, or at least attempts at rigor so far have yielded inconsistent results. I've looked at what the Settings->Battery has available for power diagnostics, and one thing I noted was a lot of spurious wakeups when all radios were turned off. That's what led me to tentatively finger Privacy Guard.
I just saw the setting to show "built-in" apps on PG. I see two different entries for google.services and google.services.framework. The former has scads of wakeups - thanks for the tip. The latter has many, but a much smaller number. Did you block wakeups for both? I presume "built-in" are also "system" that others have said shouldn't be bulk-denied in PG. Are there guidelines anywhere about which are OK, which are useful, etc? (Like this case, and perhaps battery life.)

It's difficult to give tips for this, because everyones' usage is different. Get 'WakeLock Detector' and keep an eye on that when your power drain seems more intense. Disable things that make sense to disable based on that.
I know this isn't really the topic, but just because you get a new router doesn't mean you have to reconfigure everything. Why couldn't you just configure the new router with the SSID and password from the old one?

believe me, i tried that. it's stupidly tedious to enter a long keyphrase via the remote control on our tivos and only slightly less tedious on the roku (its remote is much more responsive). laptops and phones aren't as bad since they have keyboards. apparently the devices are smart enough to notice a different MAC behind the BSSID. which if you think about it, is actually a GOOD thing in terms of security, since it makes spoofing a little more difficult. granted, you'd also have to know the wpa key to successfully spoof, but it's a simple check to implement for security's sake, and i'm glad they did.
by the way, do you like fjords?

"Wakelock Detector" has certainly been enlightening. "Google Fit", which makes sense, once you think about it. But the other aspect that was even more important, I just happened to see when one of the other forums popped up on some sort of search result or other.
You have to boot your Android device on battery. If the kernel starts up on charger, it never gets into the deepest power-saving states. When I first started using Wakelock Detector, my phone showed up as being awake something like 97% of the time. Google Fit was the biggest user, but not that big. After seeing that advice I've been careful to boot on battery, and now most of the time is spent asleep. Google Fit still uses wakes as much, but when it's not, the phone is really sleeping. My normal battery life has moved out to two or three days, sometimes into a fourth. As long as I consider Google Fit worth having around, this battery life is good enough for me - there is always a decent window to recharge.

So much for that theory. A day or two back, after good battery life since this post, I noticed it draining faster. Today I looked, and sure enough, it's not going into deep sleep. I tried rebooting with all four states of wifi and cell service, and nothing has gotten deep sleep back. I think I'm going to try charging tonight, booting while charging, then rebooting after disconnecting. It would be good to have an exact and repeatable set of circumstances that cause both good and bad battery life.
