RH,
it doesn’t make any sense 🙂 the C1 and C2 computed in the phone for the two “strong” cells are much higher than the C1 & C2 of the far cell, isn’t it ?
Then there is no logical explanation about your issue… Just to be sure, check the C1 & C2 values for all the cells. The whole reselection process is based on the C1 and C2 values, and the CBQ.
They all work in the same frequency band ?
