  1. hi dears

    my brother and i have bought 2 samsung a14
    his cellphone is made by Vietnam but mine made by china both 4GB RAM..128GB both android 13
    the phone made by vietnam can dial *#0*# but mine does not

    have i bought a fake phone ?

    • If you are unable to dial a code in your phone it’s not mean that you have bought a fake phone. If your phone is taking regular One UI updates and security patches then you need not worry. Some codes are blocked in some countries due to the country specific restrictions. Or there might be some other issue with your phone.

  2. P.S. ON CHarles Hood. Samsung phone is AO2 Aand the SKU is SMA025V2KYZ. Device id. ef6168ffed3ad562. Product date 11/21 if that helps. Thank again.

  3. I bought my Samsung from walmart for Verizon use on my grandson`s account on 11/21. When I no longer needed it he had it removed it from his account. They say it is not locked, but it shows device status locked. It has been well past the 6 month time they say it should be unlocked. We have spoken to several different people and get the same answer: your phone is unlocked. Any idea? Thanks.

  4. Hi everyone

    so I have tried numerous patterns even searched google to see if i could find a pattern that looks similar or the same and so on BUT NO LUCK!!!

    I do NOT WANT TO HARD RESET – i have more than 9000 unbacked up images and documents that i cant afford 2 lose 🙁 🙁

    i tried with my Samsung account to access the phone but the remote access is apparently not activated !!!

    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.

    • How do I know if my Partner has secret apps on his phone?. It’s an A50 and if always says duel sim always on but he’s only got one sim card in upon checking and the font is faded where it says duel sim always on almost as if he must take a sim card out when home. He also uses things like Samsung dialer etc.. I can’t think off the top of my head but it shows in his goggle history. I do have sceenshots if that would help in helping someone solve my problem. Also, how do I get it back to one sim only as mine is duel aslo but because I’ve only ever used one sim (he swears he’s only ever had one too) mine doesn’t show up as duel sim always on.. I’m just baffled and want to ensure nothing is being hidden before we marry this year. It also always says on recent searches things like screenshots, downloads, secure files, secret mode etc.. please ???? any help I’d massively appreciate.

      • You should not marry, or even be with, somebody whom you do not trust. If you feel that it’s necessary to go through your partners phone all the time to see if they’re being honest with you then you have a big problem and it’s definitely not going to get solved on here!

  5. 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, 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.

  6. 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

By reporting them and complaining about them it gets noted in their commpany files and well if we all start doing our part them asshole will probly quit making it so dam hard cause lest face it no one wants a bunch of Tarnishes on their company name i mean isntthata sign of bad business have a whole shit ton of bad marks. point being file a complaint with the FCC THEY SUPOSEDLY CAN BE RECHED HERE FOR (FONE-1-888-225-5322) AND (ALSO THEY HAVE A VIDEOPHONE LINE- 1-844-432-2275) and well i cant say itll even fix your issue right awy but i do bet its easier and less of a headache thn trying to deal with boost (AKA SPRINT). Please know that its not going to be easy but i promise itll be wroth it cause its a law and they all really just do what they want and i really hate sprint.

      • 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.

        • I had this same problem. Well my husband has boost, had a phone but UPGRADED TO A MORE EXPENSIVE ONE. ONE THAT HE WAS STILL PAYING OFF, So how do they thank like a 15 year customer who bought a phone and liked a nicer one ? They wont unlock the old phone. Ok, it wasnt turned on a year … Because it was transferred to a new phone, so the actual device wasnt on a year but the service was and whats more important to the phone service Provider??? The phone? They arent the phones manufacturer…so the phone shouldn’t be the thing “active” for a year. But the service. Like how stupid.

    • 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.
