Neither model is recommended. 860 has many problems and is highly repairable. Many models have the problem of data loss. You can Baidu it. Many machine friends have this problem, and the data of the model suddenly disappeared. One more thing, 860 brush machine is very risky, and the probability of brick formation is very high. Several ROM machines in the forum are all bricks, so the playability of this machine is not high.

LG's P990 uses the CPU of Tegra 2. Due to official design reasons, many machines fell asleep and could not wake up. You can also look at Baidu. There are many situations. This is also the design reason of CPU, and there is no way to deal with it when it appears. So it is not recommended to buy these two machines. If you want to buy dual core, you can consider HTC G 14 or Samsung i9 100.
