Is your Android Head-Unit faking its hardware specifications?
I own a 2013 Chevrolet Sail. About a year back going with the trend, I upgraded the head unit on my car with a Android Head Unit. The unit was procured from Foxfire (Delhi based) and I was promised that I will be sent the 2GB RAM & 16GB Internal memory unit. The unit shows the same configuration under system settings along with Android version as 8.1Go. I opted for higher RAM since I knew that android slows down with version upgrades having experienced the same in case of android based mobile phone.
The unit is working well and honestly I don't have any issues with the unit until now except for the fact that at times the lag is too much and also I like the maps to be minimized instead of taking the whole screen space.
