    WHAT THE HELL NOW… i am currently only able to try a new pattern every 5mins it was 30seconds then became 3mins and currently at 5mins


    • The carrier has them Blocked whether you are paid off your phone or not. Those codes can damage your phone more than they can help so they block them. I asked my Carrier the same thing and flat out told me that. My phone is unlocked without root permission because samsung won’t allow it on some models, My phone is completely paid off and I don’t have a warranty left on it and he still wouldn’t do it. That is samsungs only fault if you ask me.

  2. I have a Samsung galaxy s21 that I had lost and found it yesterday but I don’t remember the 4 digit pass code too. I have tried every code I can think of so now I can only try different one every 30 seconds. I don’t want to do a factory reset or a data dump. It has my nephew that passed away on it and I don’t want to lose those pics. If there is anyone that can help please tell me how to do so and keep all of my info on the phone. My email address is [email protected], also i will check on here for any updates or reply’s. Thanks Heather

    • There are 10000 4 digit combinations of the numbers 0 to 9999. As long as your phone allows it, you could try 100 combinations each day. At worst you’ll crack it in a 100 days. Just start at 0000, 0001,0002 etc… Good luck.

  3. I need to unlock my Samsung Galaxy A 13 5g. I have the IMEI number. Boost mobile is refusing to help, even though I have had an account in good standing for 5 years. I just purchased this phone in the last 30 days and am being told I have to have this new phone activated for 12 months before they will unlock! I have to switch carriers as I have no signal where I have moved. Please help

  4. Dear
    auto signal is not working when we go some where signal is not there, then even though we come back to signal area, automatically phone is not catching signal Why

      • Not Boost Mobile. I fought with them for 2 weeks, including corporate office. They refused to unlock my phone because I had it less than a year, despite being a customer for 5 years. Had to go to BBB before I got anywhere.

    • If you think your Samsung phone is hacked, then factory reset your smartphone and change all of your account passwords, security pin in your phone, everything will be in control. Make sure to take a complete backup of your data in external storage media before doing factory reset.
      And only install the required apps from google play store.
