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.
I have relatively the same issue. At this point I’m guessing I bought a samsung ripoff

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!

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.

You must have phone paid off and sign a waiver releasing warranty
ok so now i know that with unlocking carriers are anything but willing to do so. but the other thing i know is you mine as well flush the darn thing down the tolilet cause that is way less of a dam headache then dealing with Sprint… wich boost is a branch from sprint. But little do most people know that back in like 2010 2011some wherein there Obmama passed a law that warrites phone compyies to allow 3 FREE UNLOCK A YEAR PER COMPANY, and when they dont hold up their end of it your spouse to report them (wich no one dose report them). 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.
And only install the required apps from google play store.
