I'm having a problem with my application, it's an application to have several accounts whatsaApp, Viber, Facebook ..on the same smartphone.
it does not work properly, for the opening of an additional account WhatsApp for example, the user does not receive validation SMS and sometimes he receives it but too late (about 10 minutes)
The goal is to receive the SMS instantly or less than 1 minute.
1) it is necessary to repair the application to receive SMS validation of account WhatsApp, Facebook, Viber ... (reception of the SMS in less than a minute)
2) if it's repaired, you send me an Apk to test
3) If the test is good, you publish it on Google Play Stor
4) you send me the source code and the complete file
