Hi,
I'm considering an SII but want to know something first:
I currently have a Desire and is has a very annoying bug (many people are affected but only a few know about this). It's an official Android bug and has the number #2207.
This is how the bug affects me:
1. Device is connected to 3G.
2. Connect device to WiFi. 3G data connection closes as usual.
3. Connect device to charger (Policies: WiFi always on/WiFi always on while charging).
4. Charge it for more than 3 hours (most likely over night).
5. In the morning, disconnect the device from the charger & put it in your pocket (WiFi still on).
6. Leave the WiFi-radius.
7. Now the problem is: 3G data won't turn on. If you switch the display on (e.g. 15 minutes after leaving the WiFi-radius) there's still the WiFi-icon on the screen. A few seconds after that, it vanishes but the 3G-icon does not show up. In fact, the whole time between leaving the WiFi and now, there was no data connection anymore.
Solution: Reboot or Airplanemode On/Off
This is so annoying!
BTW: It is important that you have to charge it (without waking the display) for more than 3 hours for the bug to appear.
I don't know exactly why I have this bug but several other people (having other devices an ROMs) have it too. There's even a fix on the Android Market (WifiFixerFree) that kinda works... but it's very sad that Android has such a critical bug until now.
My question: Does the SII have this bug? Maybe someone with an identical WiFi-charging-behaviour as me can answer this?
Thanks!
Nobody? 10chars
Never heard that one before on SGS 1 nor 2 .

I can confirm that at least my sgs2 turns the mobile data properly on when i leave my wifi-range in the morning.
Sent from my GT-I9100 using XDA App
I can confirm that there is a bug with the wifi after you plug in the phone to charge.
Okay... contradicting opinions. Anyone else?
Switches fine for me when driving away in the morning and it did on my HTC Desire too.
After a very few days I have this amazing phone,
I managed to install on it Cognition v1.5 & Speedmod T27 kernel.
Im very satisfied with the results, but I have some questions left open which I hope you can help me with:
1. There's a 1sec delay when turning the screen on. Is it because the CPU is set to 200MHz while the device is sleeping? Is there a (safe) way to deal with it?
2. I still have my old Capdase usb charger from my old iphone, it has 2USB exits and its "works with iphone" crap. It outputs 1A. Can I safely use it? *Worth to mention that my (original) home charger outputs 0.7A
3. While taking a photo there's a delay from the second I press the button till the time it finishes saving and allows me to take the next photo. is it normal? I shoot 8MP photos.
4. What is the fastest protocol to copy to/from the device files from my computer? Which protocols do I need Kies installed and which I dont?
To upload photos/songs/movies do I have to use Kies?
5. Can I add to the standard lockscreen more details? Like new emails?
6. Is there a good car application? One that will recognize Im in the car once a BT connection was made, and replace the lockscreen for one with few icons of my choice? I guess a profile application is needed seperately, will it consume high power from the battery?
7. I use Hackers keyboard, its great but when Im in landscape mode, there's too many rows, causing the buttons to be very small. I wish to know if there's a good settings you know to make it have bigger buttons on landscape (even removing numbers row, which I dont know if possible)
8. I just woke up and found that the device was awake for a long time. even so, It lost only 4-5% during the night..which is ok, as bt,3g was on.
I had also a few applications left open: kies air (just waiting to start, not working with server on!), my orange, gmail..
But it doesnt matters anyway, as they consume only ram (right..?) so...What do I do next, in order to find the cause? or maybe I shouldnt be worried at all? the battery drain was normal for the night.
Its pretty long..I know. I appreciate it if you can help me out.
Thanks
Ok, I'll bite.
4. I just use usb mass storage mode. Just plug in via USB, and select the option on your phone to enable mass storage mode. I didn't install any of the Samsung crapware. You can copy any files you like to the device this way.
5. No, the stock lockscreen only shows new SMS messages. If you want more information, you could try WidgetLocker. Keep in mind it could impact battery performance though. It's either that, or you flash a custom rom like cm7.
7. Try a different keyboard. I like swiftkey.
8. Assuming you sleep 6 hours + over night, losing 4 - 5% is not something to complain about. That's excellent battery drain for idle.
Thanks for the quick response.
I tried another keyboard and it works better now.
though, I do have some other questions left open which I hope to get a reply from you guys.
Thanks

Thank you. The app idea seems great.
I'll try it out tonight.
What about the charger? is it safe to use it even tough it outputs 1A (instead of the 0.7A of my home charger)
Im looking for a Android powered GSM phone that will automatically turn itself back on if the battery is dead and power is reconnected.
I want to stash this in my vintage automobile and use tracking software to locate the vehicle in the unfortunate event its stolen. The only issue I need to solve is if the battery dies and the phone turns off how to turn it back on automatically. I plan to put the device in the door panels so access will be difficult.
Does anyone know of a phone that does this?
Not sure where to post a question like this so I figured I'd start here.

Please check NoMoarPowah! app from Chainfire - https://play.google.com/store/apps/details?id=eu.chainfire.nomoarpowah&hl=en
NoMoarPowah! can automatically reboot into Android when charging is done. Either when fully charged, or when the battery level reaches 15% and Android has enough juice to run.
The app is known to work on the following devices -
Tested on the following devices:
- Samsung Galaxy S (I9000) and family
- Samsung Galaxy S2 (I9100) and family
- Samsung Galaxy Tab 7" (P1000) and family
- Samsung Droid Charge
- Samsung/T-Mobile Sidekick 4G
- Samsung Continuum (ticker overlaps)
Awesome thank you!!
Kind of a useless app, since you have to select your option each use. May as well just plug in and power up.

you should try with Tasker (but that's not a free app, unfortunately)
Car Charging
Intelligent Approach,
I have also did the same thing but with some alteration and continue improvements to it for my vehicle security, i also did the same but putted the phone in dashboard and connected it to car cigarette lighter socket internally,(simple wiring), whenever car starts, it will start charging and Battery Booster apps Prevents Overcharge.
But currently i have hidden my Phone Near Speakers at the Back, and integrated it with Car Key less entry Remote (Car Security), so when ever some Opens my Car Doors, Car security Sends 12v Current to Siren as well as Car Charger that is connected to Mobile.
My Mobile is Programmed using an simple App that Call my Phone Number whenever It detects "Car Charger Connected" Event.
In short I get informed by my car in case of Un Authorize Access simple.
Keep it Up.
Anjum
how do you detect car charger connected event programmatically?
hi greatanjum,
thanks for your interesting post.
how do you detect car charger connected event programmatically?
could you please post a source code snippet about this?
Thank you
silvio
P.S. : I think I've gotted myself ... Using BatteryManager and its BATTERY_PLUGGED_* and EXTRA PLUGGED ...
Am I right?

if you flash TWRP and turn your phone off soon as it is connected to a charger it will boot into recovery, with that being said you easily the partition it boots into from recovery to system
i know this is a tad old post but it was near the top of google search so others may still find this thread useful
but samsung galaxy europa (its quite old and cheap £/$20 or less unlocked and locked) phone seem to work well for me only modification you have to make to the phone is the power button needs to be held down (at the start i used a clamp or large paperclip), so soon as power is received it turns on even after full power drain as when the charger is powered up it starts the auto charge which then checks the keys and sees the power/hangup button is pressed (power button is ignored as long as its left constantly held down so it not turn off) o and make sure sound is set to silent or the low battery warning will blaring away when it is running low (i do believe there is a extended battery you can get for the phone as well)
i use FollowMee for tracking and wheresmydroid as backup (has sms keyword triggering) FollowMee me never failed me) only issue is you need lots of account with wheresmydroid if you have more then 2 devices (assuming you want to use it to track via website if not the SMS keyword GPS one off tracking can be useful and it will use google WiFi Geolocation if GPS fails to work and a wifi access point is in range and you have mobile data) FollowMee does have a one off $3 or $6 payment for full 15-30 day history unlock (but works fine as free as well but will only show one current location at a time no history)
and disabled all automatic updates on google play (make sure you open google play a number of times with 5 minute delay between each open so it installs the newer version and let it update or it might get stuck in a loop and eat all mobile data) on the phone and push updates so only the app uses data (you could probably get away with a M2M sim as well), also set the phone to 2G only as 3G is bit flaky on samsung phones and 2G uses nearly no power as well
I'm running on stock 4.1.2 and mobile data is always turned off. "Keep Wi-Fi on during sleep" is set to "Only when plugged in" so the phone should only connect to Wi-Fi when it's in use. It seems that the phone periodically connects to Wi-Fi even though it's been idle for extended periods (e.g. an hour) because it's able to deliver notifications (e.g. gmail and hangouts). Other Android devices that I have, including Nexus devices with the same settings don't deliver notifications until they are "awoken".
This might also explain where a lot of battery goes. Does anyone else experience this and does anyone know if other phones/brands/models behave like this?
I presume you got an app that keeps waking the phone up every so often. Which then enables Wi-Fi to activate. Or an app stopping your device from sleeping properly. If phone is on charge then Wi-Fi on all time.
Wrong forum by the way Q&A forum.

Thanks for the reply and sorry for posting in the wrong place.
I installed Wakelock Detector and I can seen numerous "CPU wakelocks" and "wakeup triggers" but no "screen wakelocks", so I didn't expect a Wi-Fi connection to be made unless I turned the screen on and started using the phone? Perhaps I misunderstand the meaning of "Keep Wi-Fi on during sleep", especially the meaning of "sleep"? And, it still doesn't explain why other devices with the same apps installed don't behave this way. That's why I wondered if it was something to do with mods that Samsung have made to the software?

The meaning of "Sleep" in Android is when the CPU is in a mode called deep sleep, the device is set to a really low power setting so it will just run, apps can wake the device up ie take it out of deep sleep if they need to sync with a server, etc and this is what a wake lock up, an app waking the device up, and as the device is out of deep sleep for those few seconds it can switch wifi on, I personally keep wifi and mobile data on all the time so I don't know much about it.
Thanks, it looks like I have misunderstood the meaning of "sleep". I do have apps that would run periodically.
For example I use SugarSync, which I have set to only backup while on Wi-Fi and when the device is plugged in. I assume that it will have a timer set (or cron job in the old speak) so that the app can run and check for the required conditions before attempting to backup? I guess when this happens, Wi-Fi might connect and any other app that wants Wi-Fi (like Gmail or Hangouts) would take advantage of the connection? I suppose that my older devices (that run Android 2.3) might not have time to connect and so don't get the notifications that the Galaxy S3 does?
Hi all,
this is my very first post here on xda, so please forgive me if this is not the proper section for my thread. I searched for other thread about similar issues, but I didn't find anyone. I'm Italian, so I even hope to not being wrong in English writing.
I recently bought (on November 2014) an Huawei Ascend Y550-L01 (Android 4.4.4, EMUI 2.3, ROM B137), coming from a (Portuguese) Samsung Galaxy Y Pro GT-B5512. Soon I experienced a very strange GPS behaviour: GPS turns itself off. No problem in signal fixing, nor in quality or precision. It simply deactivates.
First I noticed this using the OruxMaps app (which works fine on many phones, even my old one), simply recording the track. Indeed, at the beginning the app was being killed (because of the integrated task-killer) when screen was off, but after setting it as a "protected" app, when I record a track, GPS works while screen is on and, if screen turns off, then most of the times (not always) GPS is deactivated from within Android settings.
I even received (from the purchasing time) some GPS errors while in the home screen... I don't remember exactly that error, but in a fast Internet search it was told being caused from the weather widget, precisely from the "actual position" setting. I deactivated it and added manually my town and those errors were gone.
Then I noted another strange behaviour: GPS turns off even in standby, during night. It is on "extreme precision" on evening and it's off at morning. Sometimes I notice these deactivation (in the notification menu or into the energy saving widget) while I'm using the phone (but always when screens is off), without any error or message popping out... It simply gets deactivated.
Any other experiencing this strange issue? What could be the cause? I sent a mail to official support, but they asked me to take the phone in a service point... I can't stay without phone, so I would like to avoid this if it's not strictly needed.
I think it's a ROM issue (said that even in the mail), but unfortunately still there is no alternative one (or at least I found none). I think also that (almost) every app that uses GPS suffers for the same behaviour I faced using OruxMaps.
PS: phone IS rooted by a couple of week, but I'm facing this issue from the first day.
What the hell is going on? Any help, idea or trying suggestion is appreciated...
Many thanks!
Up?
I also see strange problems on the Y550-L01 connected to GPS.
In my case the GPS does not disconnect completely, but during car navigation the signal gets lost from time to time (tested with different navigation apps).
This is only the case when the Y550 is NOT connected to the charger. If I connect it to the power supply, GPS works quite reliable and accurate!
For me this sounds like a software problem (maybe connected to a power saving mode?). I hope a firmware update will fix this soon.
Even to me this is a firmware issue. Before of your answer, I was really beginning to think it's a fault of my phone. Now that I'm not the only one, I went back to think of a bug.
If it is a power save problem, then try to use this app to stop the power save mode :
https://play.google.com/store/apps/details?id=eu.thedarken.wl
(ultra light : 35K, free/no adds)
"Wake Lock gives you control over the Android Power- and WifiManager.
For example, you can force the PowerManager to keep the screen on or have the CPU still running in standby mode or make sure the Wifi connection keeps running at full performance.
You can use it on any android phone or tablet.
Use it to keep the screen on in full brightness or dimmed mode during movies or slideshows.
To make sure the CPU is still running in the background doing your tasks when you press the standby button."
Thank you for the report.
It seems that the new huaweï G620S has the same GPS problem :

Any news of an Huaweï update ? Hope yes...

Hi! Better post your question in our small Huawei Ascend Y550 thread. Maybe there someone of us can help.
If you understand German:
http://www.android-hilfe.de/huawei-...gation-unzuverlaessig-nur-im-akkubetrieb.html
These folks have the same proplem, but no solution.
Try it while a charger is attached.
