I have the same trouble with my Ulefone Gemini
It keeps flashing that message every few seconds, non-stop. I attempted, under settings, to force stop the program from running. That only works for about a minute. But after a minute the same redundant message keeps appearing!
Unfortunately, the phone software prevents, or blocks, me from uninstalling the culprit: the offending "Bingo Launcher".
From my understanding, I can only remove the offending program if I "root" my phone via some custom ROM. However, I am unable to find any modified ROMs online. Despite a thorough search online, the only available custom ROMS are only available for other models like the Ulefone Metal, or others.
Rebooting does not stop the offending program, Bingo Launcher, from redundantly sending the message, "Bingo failed to launch..."
When I hold down the "on/off" button, I am not offered an option for a "so-called" safe mode". But therein it offers a, "Super Saver" mode.... Whatever that is. I tried it - This mode only gives me a phone dialing pad. While in it, I did not see the offending message.
Does anyone know how to stop the offending message? How to get rid of the offending program? Or best yet - where I can get a custom ROM for the Ulefone Gemini?
Big thanks out to anyone that can help!!!
