    Reply
    • Hi, the problems sometime happen because the Wifi router station is not compatible with our phone, therefore your Samsung Galaxy S Duos can not connect to that Wifi. Please try to use other different Wifi connection to make sure your phone Wifi is ok or not. We recommended to use some free Wifi (without security protection just for make sure).

      Reply
    • Hi, please try again to do hard reset or reformat your Samsung Galaxy GT S7562, after hard reset finish, please do not login to any Google or Samsung account. Without any account, you can try to use your phone just for testing. Sometime if we already have or install bad applications, Google or Samsung account will keep backup to cloud for that applications and setting, therefore we should try to hard reset and not login first to ignore automatic restore to your phone if the freeze problem comes from applications.

    • Hi, please try to do hard reset or master format to factory default, but do not forget to backup important data if you can. If you can not access Setting menu, then you have to hard reset using hardware button combination key like steps at #Option 2 above.

    • Hi, please find some installed applications at your Samsung Galaxy S Duos that maybe make your wifi automatically turn off, like battery saver or something like that. If you still can not find that kind of applications, then you have to do hard reset or master format to reset all setting back to factory default, but of course all important data and installed applications will be remove or wipe from your Samsung Galaxy S Duos, therefore we suggest to do backup before performing hard reset.

    • Hi, usually MMI CODE use when we want to check balance or top-up our balance in GSM number with special code start with * [some number] #. There are some possibilities, but mostly this problem happen related to your network provider. You can first try to ask network provider to make sure your code is right. Then they also can try with different simcard. If you have some friends with different provider service, then you also can try to access they special code at your Samsung Galaxy S Duos. We are not sure weather this problems can solved using hard reset, but you can consider to do that.

    • Hi, if you forgot pin code for Samsung Galaxy S Duos, then you can try to unlock or bypass using Google account. Please give several time wrong answer continuously until your Samsung Galaxy S Duos become freeze or locked, you can find Forgot Password button, press this button and unlock forgotten security pin with your Google account username and password that you have signed in before. If you still can not access Google account, then you have to do hard reset using hardware button combination key.

    • Hi, doing hard reset or reformat will reset all setting of your Samsung Galaxy S Duos back to factory default. Usually your problems will solved if that situations happen because applications problems. Please try again to hard reset with software menu, then after hard reset, do not sign-in with any account to ignore the auto restore that might happen before. At this situations your phone already reset back to factory default and everything will work like new again, please test weather your problems already solved or not at your Samsung Galaxy S Duos.
