This unofficial app announces the start of the campaign, when mobile operator Kaktus doubles the top-up credit. So you will never miss it again 😀
You can find out more on the official website of Kaktus: https://www.mujkaktus.cz/chces-pridat
I don't get notifications, what should I do?
1. If you have Android 12 or later, make sure that the app is not in unused applications that have notifications blocked.
You can find it in Settings > Applications > Unused applications.
It is necessary to verify it immediately, as soon as you find out that you did not receive the notification, even before you try to open the app. Because when you open it, it will disappear from the list and will return there only after some time, when you do not open it.
2. Open the app and check that you can see the text "Receipt of notifications for the Kaktus charger is active" in the app. It appears just below the Recent Notifications tab and should appear there within a minute of first boot.
3. If you use a task killer, battery saver or something similar, enable Kaktus Charger in it so that it can run in the background and display notifications. You don't have to worry, the app is designed to consume a minimum of battery and memory.
Some manufacturers, such as Asus, Huawei, Xiaomi or Samsung, already include such applications in the base, so try looking in the battery settings or similar to see if there is any "consumption optimization" turned on for the charger.
Tutorials (in English) are available at https://dontkillmyapp.com/
3. If even that doesn't work, write to me. Either in the feedback for the application here on Google Play, or to the email zkkn.apps+kaktus@gmail.com and we will check it together.
This is not an official app. Kaktus (T-Mobile CZ a.s.) is not its author, nor does it manage it in any way, so the app may not always work correctly.
So use it only at your own risk! 😉
