M4 Aqua screen have red blobs
Hi @Lazershot, sorry to hear about this. 
Do these red blobs always appear on the screen on your phone or are they only visible when you are using a certain application or service? If you have the time to take a screenshot and upload it here, that would be much appreciated!
I would recommend that you start with doing the screen test in your phone, which you can find in Settings > About phone > Diagnostics > Test > Display.
Let me know if they are visible in this test as well!
I done that you wanted and its still not gone i send my phone to service and it was gone servel days later the blobs are back
Hi again!
Oh, I'm so sorry to hear about that. 
Do you know if they repaired your device at the service centre, for example, changed the display or other parts in the phone? In the Nordic market where I'm situated you receive a note from the service centre where you can read about what was done to the phone when the phone was serviced.
Let me know what they did at the service centre!
