Conducted an experiment on three phones (iPhone, Samsung and Umidigi).
All phones were in sleep mode and were connected to one wifi.
the sent letter to the email the first came to the iPhone after 3 seconds, the second to Samsung - 5 seconds and to umidigi after 4 minutes !!!
On samsung and umidigi built-in mail application gmail.
From electronic wallets applications, notifications come with even greater delay, the delay is from several minutes to a day, it is also noted that some notifications do not come at all.
My friend has the same model of umidigi bought a month earlier and he has exactly the same problem with delayed notifications on the phone.
When the screen is unlocked, then all notifications immediately appear, in the phone, sleep mode disables the full operation of the notification center, which is completely unacceptable and, as can be seen from my experiment, this is not on any other phone. |
