I bought the DOPO D7018 7" tablet a while back and have had problems ever since with programs closing on me. Games would freeze and then close the browser also closes alot and its just slow overall. I took the back off to see if something might be wrong inside but it looked fine. I noticed that its guts are allwinner A13, I have another 7" A13 tablet I bought from Allwinner before and it works great, way better than the DOPO D7018. I dont know much about rooting and firmware and stuff, but is there a way to get it to perform better? Also the DOPO is android 4.1.1 and my other tablet is 4.0.4
