How do i turn off the 3g on the samsung s galaxy gt-19000 and conserve battery?

1. With the Samsung Galaxy TAB turned off, press and hold the VOLUME Down button, and then briefly press the POWER button.

Note: If you see "Downloading" on the screen with an Android shoveling you pressed the wrong Volume key. Remove and reinsert the battery and try again.



It should hard reset any of these tablets:
Reset GT-P6210 Galaxy Tab Plus 7.0 WIFI
Reset GT-P6200 Galaxy Tab Plus 7.0 WIFI + 3G
Reset GT-P6810 Galaxy Tab 7.7 WIFI
Reset GT-P6800 Galaxy Tab 7.7 WIFI + 3G
Reset GT-P7310 Galaxy Tab 8.9 WIFI
Reset GT-P7300 Galaxy Tab 8.9 WIFI + 3G
Reset GT-P7510 Galaxy Tab 10.1 WIFI
Reset GT-P7500 Galaxy Tab 10.1 WIFI + 3G

Settings > More Setting > Network Settings > Mobile Networks > Network Mode > WCDMA Only or WCDMA/GSM (auto connect)

WCDMA Only is is you only want to use 3G.
If you want that your phone should switch between 2G and 3G mode automatically, use auto connect option.

For this, your SIM Must support 3G services.

From official website of Samsung

To change language on Samsung Galaxy S GT-19000:

1. Go to SETTINGS ( gear wheel/cog icon )
2. Then select "Locale and text" (it's the tenth item down)
3. Then "Select locale" and select English.

Before you can attach a photo to a contact, you should first ensure that the number is saved on your phone and not sim card.
Then, you scroll to the number, select options, then add image to the contact.

Or, from the image location, select the image you want to add to the contact, then 'use image', select the option to use as contact image, under the condition that the contact in question is saved on your phone.

If the contact is saved on the simcard, simply select options, then move it to phone memory.

Hope that helped?
Success.

call your service provider.. if MMS is active, they will send you the settings on your device free...

Settings > Language and Keyboard > Select Locale
Then choose your language
