Re: 4 buttons on the bottom keep pressing :(
This thread provided the information I needed to get Sprint (and Samsung) on board with a solution for the Galaxy S II 'Epic 4G Touch' model number SPH-D710.
I got verification that the problem with the Sprint S2 phones is also caused by RF interference. Here is the reply:
The hard part is convincing your repair center to actually perform the repair-- I got stonewalled, even though the fix information was attached to my repair ticket. Either print out the pertinent parts of the Sprint forums thread and take it into your local Sprint repair center, or contact Christy through the aforementioned Sprint help forums for a repair ticket.
When the radio turns up power to maintain connection with the towers it can cause Electronic Noise to leak over the connection between the capacitive buttons at the bottom of the handset and the main board, making the phone think that there was a key press. This is due to a piece of shielding tape on the device not being up to snuff. The tape can't be replaced on its own in store, the entire screen assembly needs to be replaced.
This issue took quite a bit of time to track down and determine a root cause by Sprint/Samsung because of the large number of devices in the field with varying parts since launch and the multitude of potential causes. It needed to be determined how widespread the issue was, and the different types of hardware affected by this versus other issues with potentially similar symptoms.
The MENU button being "pressed" on its own is considered a known issue and can be fixed in a Service and Repair store by replacing the screen assembly (The replacement parts from Samsung are a combined LCD/TSP assembly from the factory so they are both replaced at once). It does appear more apparent in low signal/roaming environments due to the nature of the issue. If a store does not have parts available or is unable to fix it, they can exchange the device for you. Exchanges will be for the same model refurbished device, just as if you went through Samsung to have it repaired/replaced. The refurbished devices should have the fixed part in place already from the warehouse. If you do not have TEP/ESRP from Sprint the $50 repair fee is waived for the repair/exchange for this issue. I do not know a specific date that this was posted in the internal device solutions portal, I just checked it today specifically for this issue.
Oh, and according to the tech I talked to at the store, Jellybean is supposed to roll out in this month... yeah, doesn't look like that's happening.
