If the microphone on the headphone work, then the built in microphone near the base of the phone could be bad. If you don;t want to have the phone fixed yet, keep using the headphone or get a Bluetooth headphone set. The Galaxy S3 is quite old, in smartphone lifetime, so I suggest upgrading to a S6 or better.

Hi Cement, Sorry to hear about your Galaxy S3! Depending on the damage (if you can see the the video underneath and the touch feature works), some repair shops can fix your device for much less than the cost of a new phone. There is a company called Phone Doctors (www.PhoneDoctors.com) that offers a lens-only replacement for $150 via their mail-in repair service. These guys are AWESOME and fixed my friend's phone in no time at all. If for some reason your video is not displaying or your touch is not working, the worst-case scenario would be about $240 for a new screen (which is the LCD and Digitizer + Lens as a combined part). I do not recommend trying the "glass only" fix as you run the risk of really messing stuff up unless you have the correct equipment, which Phone Doctors has. However, this repair can most likely extend the life of your device! :)

you have to update the firmware or downgrade it depending which one is giving you problems. i had the same problem with mine. i upgrade os and facebook ran smooth hope it helps

It appears that your OS is not compatible with your phone and therefore your computer will not recognize the phone.

Do a battery spin test. Take the battery out and put it on a flat surface. Spin it like a top. If it moves, the battery is bulged in the middle and must be replaced.

To get rid of annoying virus sometimes you need to download a good antivirus or format your phone, but the virus is not the only problem. Snoopers can be a huge problem against you, so I recommend you to download a good applock to prevent your data getting lost. Protect your private photos, videos and more.

Here is another way to unlock pattern lock for Samsung Galaxy phones, and no data loss http://www.youtube.com/watch?v=lw4ueft-t_I

go to settings => lock screen => click on the 'shortcuts' or lock screen widget shortcut (forgot the name). There you can change or remove it

Now, the first thing I would advise you to do is uninstall any app you don't really need. However, many apps come with the phone, so they can not be removed. For these, and any app you do not want to remove, you can clear the cache. To do that, hit settings -> Application manager -> Slide til you see a list called "all". Now all you have to do is hit each app you want to clear the cache off, and choose "Clear data" and "Clear cache". Beware that the "clear data" option will likely delete any saved password or settings the app uses, and thus you might need to redo those settings. It may also delete some information attached to the app, so use the "clear data" option at your own risk. Tho for apps like Facebook and twitter, the option should do no harm. You can also choose to move some apps to the SD card. While I have not tried that out myself, it should push some of the stuff from internal to "external" memory. You may also want to download Clean Master. It's an app somewhat similar to CCleaner, if you are familiar with that (deletes cache and junk files). I use it myself, and it helps a bit. It's free and you can download it here: Clean Master Boost AppLock Android Apps on Google Play If you need further help, I’m available over the phone at https://www.6ya.com/expert/jason_70466cb634a57543
