How to solve the problem with password mismatch on android applications?

Question

Android

Such a problem. I install an application, for example, Instapaper, on a phone with the 5th android. I enter my email and password to login. The application constantly says that the password is incorrect. I specifically changed the application password on the computer, but on the android the same message. Until you do a password recovery from android, the application does not start there. This is not only with this application, but with a number of others.
What is it, an application bug or a trick by manufacturers to find out the user's mobile number?

Answer 1

Found the reason for such inadequate behavior of the application. After rearranging the system on the phone, I set my standard time, but the application did not "recognize" the password. As soon as I left the time 1 hour ahead, which the system determined, the application successfully accepted the password. So it's all about setting the time on your phone.

Manufacturers don't need your phone number. From the word at all.
But uncles who want to turn their affairs into a black one or steal data from you need it.
Android 5 version is already an old man and there will be many holes in it that can be used, especially if you install everything and don’t read anything the app requires access to. Or you install the APK from third-party sites (Play market is still a garbage dump with viruses, but at least it is relatively safe for the rest)
Make a full reset on the phone. If this continues then flash it. w3bsit3-dns.com + Xda-Develpoers here you will find firmware + guides on how to do it.
