  1. Can frequent factory reset damages or crashes the device? Because I used to factory reset my samsung galaxy s3 gt i 9300 since I had last february 2013. I actually did 9 reset already. Do you think it will be bad to my phone aside from considering that all the datas will be wiped out?

    1. Hi Allan Kennette Claveria,
      Thanks for coming here.
      I think it will not damages or crashes your phone as long as you do so in accordance with the procedures. Many peoples out there often doing factory reset with their phones when they have problems, and so far I have not found any reports the phones become crash or broken because too often doing factory reset. But, make sure before you do a factory reset, you should have a fully charged battery because if in the middle of a reset and your phone run out of the power then it could "brick" your phone.
      Hope this helps :)

    1. Hi Anoop Bhatia,
      Glad to see you again :)
      Since when you were realized that your phone often encountering freeze? Did you made any changes on your phone? Try to check available memory or move any files you save in the internal memory to SD card or another external storage, uninstall unused apps to free up the storage then see whether it helps. If not, you may need to do factory reset. But, before you do this, backup the data first and make sure the battery is fully charged to avoid run out power when the process is uncompleted.
      Hope this helps :)

      3. Try to restart your phone.

      Thanks for coming.
      To avoid your phone freezing, try to go to Settings-> Developer option-> change Window animation scale and Transition animation scale to 5X or you can turn it off. This will make your phone can work faster without having to load any animation.
      Hope this helps :)

      Did you phone is still slow even when you have not re-installed any apps on this? If so, try to clear RAM by holding down the Home button and select Task Manager, then tap Clear memory. If this still unable to solve the problem, then try see whether multi window is on or not on your phone, you can see it on the notification panel, see a "multi screen" option. If the multi window is on, then turn it off and see whether it helps :)

      AFAIK, the factory reset will only work to fix software issue. Due to your problem is related to the hardware problem, in this case is the battery or charger or the USB cable, then try to use another battery/charger/USB cable--lot of users encountering slow charging issue and some of them able to fix it by doing that thing-- then let see whether it helps :)

    3. Hi Bhagmattie Latchman,
      Thanks for coming.
      Try to turn off Window animation scale and Transition animation scale that you can find under Developer option under Settings menu then see whether it solve the problem. FYI, another thing that may cause the phone become slow is low internal memory, so it's important to the user to manage the phone's RAM well.

      Try to check whether the "Noise reduction" option is enabled or not on your phone. If this option is enabled, then disable it. Aside from reducing the noises in the background, activate this option can also cause a problem in the microphone signal, resulting the people who call you can't hear your voice well.

      Unfortunately, factory reset will delete all your data. That's why a user needs to backup their data first before doing factory reset. If you have installed Facebook on your phone, try to check your Facebook account from PC and see in the private album. It usually auto sync all photos taken by the phone's camera. Other, if you saved photos and videos on your SD card, take the card and hook it up to your PC and then copy all of them to your PC. However, do you remember what you have done in your phone before your phone unable to boot?

  14. HI.
    I turned off my mobile data 4g so that I could use wifi at home, but when I click on chrome or internet, it said that it is not connected even though the setting said that wifi is secured. What should I do to fix my wifi problem? Would factory reset help? How would that takes? and would it damage the phone if it stops halfway?

    1. Hi Buddy,
      Thanks for coming.
      You're right, when you're performing factory reset and stop it halfway, the process may be corrupted and it will damage your phone. Given the risk, I always put the factory reset as the last effort.
      Well, back to the case.
      Is this the first time you connect to the Wi-Fi network? If so, tap the Wi-Fi network profile and then enter the password correctly (it's case sensitive, A is different with a) then tap Connect button. If you've managed to connect, below the Wi-Fi network profile will be labelled with "Connected".

      CMIIW, theoretically factory reset will erase all your settings, files and third-party apps, but it won't revert your Android version to the default. So, your phone will remain in Android 4.3 after you did factory reset.
