please general mobile gm8 support
I also have General Mobile G510 (GM 21 Plus) and i am suffering from two things:
First, from google invasive apps and malware such ass
Second, form the crapware apps pushed by general mobile company such as
sahibinden. Also i do not have root access, so i cannot remove apps such as
GM Files etc. All i can do is disable these malware.
I do not think there will be support sooner for GM devices, since these devices are not common and only sold in Turkey i assume. I think the best option is to check a device that has the same hardware.
