GPS module should be off if not being used to conserve battery. You can set this in the setting of power saving mode (Eg, GPS module will be off in 4 minutes if no being used). When you need it you simply turn it on again from the pull down menu.

GPS will lock in a few seconds if hot start (You don't need A-GPS to get fast lock). The problem is cold start. When you open a GPS application starting with GPS module was off. A-GPS will get a lot quicker fixed in cold start.

iPhone4 will get lock within 1 minute with A-GPS from cold start (means phone connected to internet with wifi or 3G). It will get lock in 1 to 2 sec with A-GPS from hot start. However, it need 2 to 4 minute to get locks with GPS cold start (lets try turn off wifi, and turn your phone off for 30 minute and take the sim card out from you phone. Then walk outdoor turn your phone on again and open TomTom to see how long it need to get lock. It should be about 2 to 5 minutes.

I agree that iPhone4 is more affective in using A-GPS than SGS2. iPhone 4 gets lock quicker than SGS2 with A-GPS (with mobile internet connected) in cold start.

In reality, cold start is most important as you usually turn the GPS module off to conserve battery. You can imaging when you get loss in driving. You pull over and start Tomtom plus turn on your GPS module, but you need to wait in your car for 2 to 5 minute before you get lock and you can drive again. Another issue is the sensitivity of the GPS. It will help you to plan your trip if you can get GPS lock inside your home or your office. The A-GPS in iPhone 4 works well. I can get lock quick and get signal in my office and home.

I got my SGS2 last week. It takes me 2 to 5 minute to get lock with cold GPS start, and A-GPS did not help much. I could not get signal inside my office or inside my house. Surprisingly, I accidentally found my SGS2 got GPS lock when I put it on my Kitchen bench top last weekend. There is a Kitchen Aluminum Foils under my phone! After some investigation, I found that the Kitchen Aluminum Foils enhances the GPS signal. Now I got signal inside my house and quicker cold start after stick a piece of Kitchen Aluminum Foils (about 6x9 cm) on to the interior surface of the battery cover.
[Galaxy S II General] zmchu:
What do you mean cold start? Do you mean start from the GPS module off for a few hours? Your GPS module may be on all the time. Check your pull down menu to see if you GPS is off or on. It is cold start only if your GPS module has been off for a few hours.

Cold start locking < 30 sec is very fast. I don't think even iPhone can do that!
[Galaxy S II General] tanwt:
you mean the aluminium foil is inside the phone? will that cause any problems to the phone on the long run?
[Galaxy S II General] tanwt:
cold start = gps icon on but i didn't execute any gps software (eg papago, gps test) and it didn't lock on that location for days

actually leaving the gps icon on is not a big issue. it didn't use any power. only when you execute the gps software to start locking, it drains the battery very fast

i will try to see if switching off the gps icon will affect the locking performance and report here my findings
[Galaxy S II General] skanj:
thanks worked for me!
[Galaxy S II General] tanwt:
nice to hear it works for you
[Galaxy S II General] zmchu:
You can check the pull down menu to see if the GPS module is on or off. If the GPS module is off, a pop up window will show: "GPS is disabled, Show location setting?" when you open Google Navigation. If no popup window showing "GPS is disabled, Show location setting?" when you open google navigation, your GPS must be already on. This is not a cold start.
[Galaxy S II General] zmchu:
cold start = gps icon off, Hot start=gps icon on, at the time of starting gps software.
[Galaxy S II General] zmchu:
Look at the tip of power saving mode. Leaving the gps icon on will use some power. but not as much as when you execute the gps software to start locking.
[Galaxy S II General] zmchu:
No, It should not. If it does, then how about aluminum body design phones like HTC or iphones ?
[Galaxy S II General] tosheeba:
You guys should install GPS Status. My experience is that it helps in maintaining the A-GPS list updates and results in faster locks.

Search GPS Status in android market.

It worked for me.
[Galaxy S II General] JJEgan:
1 of them is the "Data Network Mode". it need to stay activated

That means you may incur data charges .

SGS2 is hardware based GPS true test is with No WiFI and no Mobile Darta connection No sim card . That will test pure GPS .

[Galaxy S II General] tanwt:
well, i did a real cold start (gps button off, on when start navigation tool)

still < 30 sec
[Galaxy S II General] dosher:
Great tip about GPS Status - thanks. But I do have one issue with this app. To close GPS Status I hit the back button once however the GPS icon remains in the status bar at the top of the screen. I have to go to Task Manager > Ram and hit Clear memory to release the GPS sensor. Anyone else getting this?
[Galaxy S II General] tanwt:
if i want to disable gps, i just use the drop down menu and disable gps
[Galaxy S II General] dosher:
You shouldn't have to disable the GPS by using the toggle in the drop down menu. Navigation apps should release the GPS sensor when they close down.

I have discovered that if you run GPS Status inside a building where it can't get a lock, it doesn't subsequently release the GPS sensor when you close down the app. The GPS icon remains in the status bar at the top of the screen, flashing.

If you run GPS Status outside, once it achieves a GPS lock, it shuts down and releases the sensor straight away.
[Galaxy S II General] zmchu:
Well, if the GPS module still on it will consume small amount of electricity. If you want to conserve your battery and you don't use GPS often (eg only once a day or once a week) then there is no point to switch on your GPS module all the time. We can use pull down menu turn it off.

Also so call hot start or cold start, it come from similarity to your car engine. This is a easy way to understand. Particularly in winter it is a lot easier to start a old truck's engine when the engine is hot, and difficult when the engine is cold (eg first in the morning). When the engine warns up it still be hot for a period of time after you turn the engine off. Re-start a hot engine is easier than a cold one. So, once your GPS get fixed, position data will stay in your phone for a period of time, eg up to a few hours (GPS still hot) even you turn off GPS. During this hot period GPS re-start faster. If you use A-GPS, then some position information will download from internet, which allow GPS get fix faster.

Yes you should use xrecovery

install the Rom and flash it with xrecovery , if the Rom file you downloaded is. Zip (not . Rar) go to xrecovry install custom zip and chose the file. Zip if the file. Rar unrar it and put it in backup file in xrecovery and then go to xrecovery menu select backup and restore choose restore, select the file you have put it there, when finish reboot the phone

[Acer Iconia A500] codeworks:
Hello, all.

I am having an issue with my Iconia A500. The screen will quickly shift screens back and forth on its own for a while and then it will freeze. I was hoping to reset, but since I cannot get it in to any of the menus, I am unable to do so.

Is there a way to hard reset without booting the device up using the reset hole or another way? Anyone ever seen this screen problem?

Thanks for your help.
[Acer Iconia A500] iCurmudgeon:
I found that holding the power button down for about 30 seconds will force a hard boot.

(This is specifically mentioned in the manual downloadable from Acer's site).

As for the "flickering" and refusal of the A500 to stay asleep, it seems to be related to background wifi activity. Disabling wifi before putting it to sleep will make it stay asleep. At least that happens with mine.

By the looks of things it seems like the music app is launching then quiting and launching and quiting... I don't see a screen issue but rather some kind of corruption or instability. Try a reset or uninstall/update that app.
[Acer Iconia A500] FredFrench:
i tried many reset but it doesn't worked. i tried to do the update.zip but unsuccessfully. i try to push the power button +30sec it doesn't worked too.

and i can't update or uninstall the app because i can't push on the tab because of the constantly launching/quiting.

:(
[Acer Iconia A500] gammaRascal:
Ya... I don't know man.

Is there anything you might have done to cause the behavior? SD card installed with music on it? rooted? Installed (bad) apps?

Maybe someone with more knowledge has some ideas.

You could always try to return it and get a new one...?
[Acer Iconia A500] FredFrench:
None of these.

Tab was down. Acer's warranty sent me a new one. I don't know what was the real issue because they don't said me any information.
[EVO 4G Q&A, Help & Troubleshooting] fldash:
Awesome. Was running CM7 just fine. Even with 4G access and the WiMAX Keys checker telling me my keys were fine. Decided to flash a Sense-based ROM to do the 3G/4G speed fix (remove Sprint proxy)

I flashed the ROM, dialed ##3283#, entered my MSL, went to Advanced, changed HTTP PD Proxy port from 8085 to 0 and HTTP PD Proxy address from pd.vog.sprintpcs.com to 0.0.0.0.

I hit back, went to Data Profile, hit Menu, then selected 'Restore'. My phone rebooted.

It hung forever on Contacting Network on the hands-free activation after reboot. I hit Home key when I heard a notification and 3G was activated. I tried to use 4G, won't start. WiMAX key checker now says my RSA keys are gone.

I did the steps again, and again it never completed hands-free activation. If I go to Settings, System Updates, and try to update my profile it hangs at 'Preparing your network services'...

And now my 3G is about 100kbits/s... super slow. YAH!

Flash s-on zip, then run an RUU. Delete any rooting, unrooting, roms, mods, etc off of your SD card and take it in. Just play dumb. I had my 4g fail on my very first brand new, never been rooted Evo... so it's possible. I originally took it in because the usb port broke, but mentioned the 4g and the guy looked at me funny.

Be sure to fully unroot, because they'll try to factory reset the phone, boot into the bootloader, etc. Just tell them it stopped working out of nowhere, if they can't prove otherwise you'll be fine.

How to disable stock sms?????

I downloaded GO SMS and need to disable my stock somehow so I stop getting double messages. Any tips?
[T-Mobile LG G2x] player911:
Well normally you won't. You CAN go in and disable SMS notifications via the Messaging app directly so you don't get double notifications.

You CAN delete the APK out of system/apps if you have root, but most SMS Apps piggyback off the stock Messaging program so it is ill-advised.

Just disable notification from stock and use GO SMS. Ignore the stock app (or Hide the icon if using Launcher Pro).

+1 for monoprice

I picked up a 3ft and 6ft lengths in black and "splurged" the extra few cents to get ferrite cores and the thicker gage power wiring (28/24 vs. 28/28 as they list it).

In comparison to the Samsung OEM cable, they have "chunkier" heads with harder and thicker plastic. They don't interfere with the phone housings in any way and are much more cat-proof. My cat made swiss cheese out of the ends of one of my Samsung cables.

The thicker gage wiring option is nice if you anticipate cable abuse (stepping on it, pinching the cable in doorways, etc) - great for vehicles and small kids. The thicker wiring does however results in a notably stiffer cable, so I can't easily wrap one tightly around my palm, for example.

For the prices they charge you could easily get many for the "price of one" in a brick and mortar store, so if you're one to deliberate to excess you could just order a few different options knowing you'll get something to your liking ;).
