Main:

That could not be.

Here are questions which can help you to determine where problem is:

  1. Are you trying with default settings?
    If “yes” – pay attention that there is “Night” profile with silent alerts (only by turning screen on and LED)
    If “no” – check settings of profile in sections “Limits” and “Contact filter”
  2. Does the profile work correctly in test mode?
    Open profile, click on “ ⋮ > Try”
  3. Do alerts work for missed calls?
  4. Do alerts work for missed SMS?

The reason is in phone settings or installed third-party applications for “Optimization”.

  1. Disable power-saving modes in phone settings or add Prof Reminder to the whitelist (exclude list)
    For Sony Xperia users – it’s in STAMINA power-saving mode settings.
  2. In applications for “Optimization” (like Clean Master, Greenify) or Task Killers add Prof Reminder to the whitelist (exclude list).
  3. Allow to work application in background mode.
  1. Does the profile work correctly in test mode? (open profile, click on “ ⋮ > Try”)
    If yes – check settings of profile in section “Basic”
    If no – go to to the next step
  2. Check settings of profile in sections “Limits” and “Contact filter”.
    Those options – additional conditions for starting profile.
  3. Make sure that application have permission “Telephone”.
    This permission is needed for detection of missed calls. Application cannot perform calling.
  4. If you are using third-party dialer application then
    1. Turn off option for deleting (replacing) stock notifications:
      Application Where you can find settings
      Pixel Phone “ ⋮ > Preferences > General > Missed call notification”
      True Caller “ ≡ > Settings > General > Allow Notification access”
      Drupe “Settings > Missed calls > Call notification”
      2GIS Dialer “ ≡ > Settings > Notifications > Replace system notifications”
      ExDialer “ ⋮ > Preferences > Plugin” disable “xMissedCall”
      (FUG) Phone + Contacts and Calls Turn off access to the notifications for this application in phone settings
      DW Contacts & Phone & Dialer « ⋮ > Settings > Phone > Replace Missed call notification»
      Other applications Check all options

      Or add new profile “for applications” and add your dialer application into the list.

    2. Check work with stock (default) dialer application
  1. Does the profile work correctly in test mode? (open profile, click on “ ⋮ > Try”)
    If yes – check settings of profile in section “Basic”
    If no – go to to the next step
  2. Check settings of profile in sections “Limits” and “Contact filter”.
    Those options – additional conditions for starting profile.
  3. Make sure that application have permission “SMS”.
    This permission is needed for detection of unread text messages. Application cannot send text messages.
  4. If you are using third-party application for messages then check work with stock (default) application for messages. So, application Textra SMS earlier version 3.33 contains error.

 

Error in the application Textra SMS:

Older versions of Textra SMS contains error – all received messages were marked as read in internal database. Therefore, reminders for messages did not work.

In Textra SMS version 3.33, this bug is fixed.

  1. Does the profile work correctly in test mode? (open profile, click on “ ⋮ > Try”)
    • If yes – check settings of profile in section “Basic”
    • If no – go to to the next step
  2. Check settings of profile in sections “Limits” and “Contact filter”
    Those options – additional conditions for starting profile.
  3. If Android version on your device is less than 4.3,
    then pay attention that, by default, alerts for applications will stop after screen unlock.
  4. Make sure that application posts removable notification in the status bar
    Here is screenshot of removable notification. It can be deleted by swipe to the left or right, as well as by pressing button “Delete all” (marked by red circle).
    en_Removable_Notifications
    To check, you can use the test application 
    Test_Notification-1.2.0.apk

Paid version:

  1. Alerts for any other applications (WhatsApp, Viber, Line, Skype, Facebook, Twitter, Instagram, …).
    Alerts can work for any applications which can post removable notification in status bar (notification area).
  2. Contact filter. It allows to define:
    • White list – alerts will start only for defined contacts (for example for family members or colleagues)
    • Black list – alerts will start for all except defined contacts

Price may be different in different countries.

To see the price:

  1. Turn on Internet
  2. Click on “ ≡ > Update to Premium version > Buy ” in the application
  3. In confirmation window from Google Play you will see price

The entire payment process is completely controlled by Google.

If you are getting “Error: 3” then probably application Google Play Services isn’t installed.

Try following tips:

  1. Clear Cache for application “Google Play services”
    It can be done via stock application manager.
    en_ClearCache
  2. Clear Cache for applications “Google Play services” and “Google Play”
  3. Try later (problem can be on Google billing servers)
  4. Try to initiate payment in any other application
    Just to check that confirmation window for Google Play will open correctly. Real payments isn’t needed.
  5. Try to find answer in Google Play support
  6. Try to find answer here and here

No, it is possible only via Google Play.

If you already bought it then there is no need to purchase the app again.

To restore paid version:

  1. Turn on Internet
  2. If you add several Google accounts
    then, make sure that main (first) account is the same as before (when you bought it)
  3. Start Prof Reminder
    if it’s already started then close it by pressing Back button and start it again

 

If this does not help – clear Data for applications “Google Play services» and «Google Play» and try again.

Flash or LED:

Unfortunately, in Android flash controlling isn’t standardized. For most devices method “Standard” will work. For several phones is required to choose other suitable method.

Try to change flash controlling method. Click on “ ≡ > Settings > Flash”.

Pay attention that, on several devices flash will work only when screen is turned on. This is hardware restriction.

There are many factors which influence on correct work of LED.

First of all you should check work of LED in test mode of profile (open profile, click on “ ⋮ > Try”).

If LED does not work in test mode then:

  1. Make sure that LED is enabled in the profile.
  2. Turn screen off while testing.
    On many devices, the LED works only when the screen is off.
  3. Try different color.
    Some devices do not support all colors. Try with red, green or blue colors.
  4. Make sure that phone settings allow to use LED for notifications.
    For example: screenshot of such setting in Samsung Galaxy S4.
    en_LedNotifications
  5. Make sure that the device is not discharged, is not connected to the charger, there are no active LED notifications.

 

If LED still does not work while testing profile then:

  • Probably your device have no LED
  • Or LED used only for displaying charge status like on phone Lenovo Vibe Shot Z90a40

If LED works correctly while testing profile, but after missed call or SMS blinks by different color then:

Try to change LED controlling method “ ≡ > Settings > LED – Control method”.

If advice didn’t help then:

This is known problem for several phones. Currently there are no 100% working solution.

Let me explain:
Unfortunately Android applications can’t control LED directly, applications only can set request to system with desired color and frequency.
Everything works fine when only one application set such request (You can check it by testing profile – open profile, click on “ ⋮ > Try”).
But when several applications set request at same time – it can become a problem.
Most of devices will use color from last request, but several phones – from first request.

This is why you can see LED color from stock application.

PS: We are trying to find workaround for this problem …

Sound:

  1. Make sure that sound is enabled in the profile.
  2. Pay attention that (by default) sound will not play if sound mode of phone is “Silent” or “Vibration”. How to change it.
  3. Pay attention that there is “Night” profile with silent alerts (only by turning screen on and LED).
    For all missed call and SMS from 23:00 till 08:00 by default such profile will be used.
  4. Setup different sound file
    Also if you store sound files on external memory card, then it’s better to move them on internal memory card.

Pay attention that there is “Night” profile which is by default configured for silent alerts (only by turnings screen on and LED). For all missed call and SMS from 23:00 till 08:00 by default such profile will be used.

Options for volume control are available in “Extended view” of profile:

  1. Open profile
  2. Click on “⋮ > Extended view”
  3. Click on “Notification” item and you will find options for volume control.
    Pay attention that profile can contain several “Notification” items.
Video - how to set volume

If volume level is still low, then select another audio channel (click on “ ≡ > Settings > Advanced > Audio channel”).

To do it:

  1. Open profile
  2. Click on “ ⋮ > Extended view”
  3. Open “Notification” and turn on desired modes in the item “Sound”

Copy sound files into folder ” / Internal_Memory_Card / media / audio / alarms” or ” / Internal_Memory_Card / media / audio / notifications”.
(Path to the memory card on different phones may vary, usually it’s “sdcard”).

If new sound is still not available then reboot phone.

Work of application:

  • All profiles are independent.
    ‘Day’ and ‘Night’ profiles – are just names. So, changing time limit in first profile will not change time limit in second profile.
  • Number of profiles is not limited.
    You can modify them, delete, or create your own.
  • Different profiles can work at the same time.
  • New event can start only one profile.
    I.e. after stopping/ending profile new profile not will started this event.
  • New event received during current notification will cause restart notifications.

Search is starting from the top.

Profile is selected if:

  • It’s enabled
  • Event type (missed call / message / …) matched
  • Event passes restriction from section “Limits”:
    • Current time is within the time limit
    • Battery level is not less than defined value
  • Event passes contact filter
  • Time is over (alerts schedule is over)
  • When all events related to the profile viewed
    Messages – in stock message client, call logs – in stock dialer.
  • On manual stop (for example by clicking on widget)
  • On screen unlocking (if such option is enabled)
  • On service disabling
  • On changing settings of profile
  • Alerts can start only if event occurred during specified period (Time from <= Current time < Time to)
  • “Time to” does not affect on interruption of notifications
  1. Duplicate profile “Day”
    In the list of profiles click on “ ⋮ > Duplicate”
  2. In first profile set alerts only for missed calls, in seconds profile set alerts only for SMS.
  3. Adjust these profiles as you wish

Other:

Correct work of options “Basic > Stop by – Screen unlock” and “Limits > Locked screen” are guaranteed only when default lock-screen is used.

Such options can work incorrectly:

  • On several deveices if stock (default) lock-screen is turned off:
    It’s recommended to disable those options or enable stock lock-screen (for example “Unlock by swipe”).
  • If installed third-party lock-screen application:
    It’s recommended to disable those options or try to specify that application in Prof Reminder settings (“ ≡ > Settings > Advanced > Lockscreen application”).

First of all – application is safe for your privacy because it:

  • Has no Internet permission
  • Has no permission for sending SMS or MMS
  • No Root access

Application have no one Unnecessary permission.

  • Run at startup
For correct work of alerts (about other applications) after startup
  • Prevent phone from sleeping
For correct work of application

No. Because for applications that use services in their work it’s not recommended.

Also size of the application is small.

This is known bug of Samsung firmwares. This bug can occurs after enabling any Accessibility service in phone settings.

You can fix it:

  • Disable all apps for Text-To-Speech
    Open system settings, point “Application manager”, tab “All”, disable “Samsung TTS” and “Google Text-to-speech engine” by clicking on them and then click on “Disable”.
  • Install other launcher from Google Play.
    For example: Nova Launcher or Go Launcher.

Make sure that you are using latest version of application.

Send your current settings by ( “ ≡ > Send feedback” ).

Prepare detailed description of a problem and answer on following questions:

  1. What exactly not working? (alerts do not start / do not stop / alerts stops earlier than expected / …)
  2. Is problem related only to one type of event? (missed call / SMS / MMS / flash on call / alerts for other applications)
  3. How often it happens? (sometimes / often / permanent / …)
  4. How it works in test mode? (open profile, click on “ ⋮ > Try”)
  5. Did you install such applications (if “yes”, then which?):
    • Third-party dialers (phones)?
    • Third-party contact managers?
    • Third-party applications for messages (for SMS)?
    • Applications for call or message blocking?
    • Applications for “optimization” or process managers? (like Clean Master, Greenify)
    • Other reminder applications?
  6. Is firmware on the phone official (standard) or modified?
