RE: T28 + 2 EXP39 (gray screnn and EXP lights turn off)
HI condor,

Sorry for the delay.
You connect two EXP39 with T28 and phone randomly turns the screen gray, it maybe because the power is not enough to support to EXP39.
So please plug in a standard power supply which is DC 5V/1.2A to the EXP39 and try again.

If the issue still exist, In order to do more troubleshootings, please describe your scenario and supply syslog level 6, config.bin and pcap and send to
