Reading every message in the threads in the forum I understand that there is no combo receiver with Android operating system working properly. I have the Viark 4K but I want to buy an Android - Combo receiver with Mars or Forever software but it works without the basic bugs such as inability to move the motor, inaccessible favorites list, screen freezes, inability to switch from Android mode to Enigma 2 and other bugs that you have mentioned. Thank you for this because you are helping all forum readers not to buy a receiver that will not be able to do what they ask. So I want you to help me choose a receiver with the fewest bugs up to 100€.
