How to change my security code if i forgot my old security code lg gw300?
Is it asking for a PUK? If it is, call your service provider...they will give it to you. If it's not asking for that code, try your phone number last 4 digits. Good luck.
How can I lock my photos in a file where no one else can view it? My phone is an Android.
Use the following apps :ABCDEFXYZBlahNo need of all these crap.Follow these steps :Make a new folder.Place all the required files in it.Make an archive i.e. make a .zip or .rar file with the folder inside it. If you want added security use password. Let it be androidlibjin.rar .Take any other useless image or file other than the file extension (.zip or .rar). It should be in the same folder as the archive. Let it be poorjoke.jpg .Open terminal emulator (or download it if you don't have, it is a must for me).Go to your folder using ls and cd. Or follow this (enter only the things in the line starting with $, without using $) :$ cd storage$ ls(00790 or something like that)emulatedselfIf you want to go in internal$ cd emulated$ cd 0$ ls your all folders show here for eg.Boss $ cd bossTo go to external, go to the other place (shown here as 00790). Don't go to self. And find your folder and go to it.Execute the following:$ cat poorjoke.jpg androidlibjin.rar > joke.jpgNow your rar file is hidden in the file joke.jpg. This (joke.jpg) would be same as poorjoke.jpg as both are .jpg. Hence, you would see the same image. So if someone opens it, he would see the image, not the rar file.To see your hidden photos,Change the extension of joke.jpg to joke.rarOpen it.Use password if you did it during initial steps.Get access to your files.After your work is done, change the extension of the file back to .jpg .You can delete poorjoke.jpg and androidlibjin.rar. But don't delete joke.jpg.If you are rooted, it is good to place that file in the file system's root so that no one who doesn't know much about Android would find it in SD card or internal.Why this and not the app? Because someone can sense something's fishy if they see the app name in your phone.This method is known as Steganography.You can do the same on Linux systems (as Android is basically a system based on Linux) using the same commands and on Windows (using copy /b file1+file2 file3 in cmd).Thanks for reading my answer!
