I bought a brand new SGS II from The Warehouse, just to be used as a backup phone and as a test device for a couple of apps.

Everything appeared ok but 2 hours in...

I receive an occasional notice stating "battery disconnected" (3 times now) - the phone stays on and I can make the message go away by touching OK.

I have not installed anything yet but the screen feels really unresponsive intermittently. It's hard to reproduce but if I swipe or touch, it is like nothing registered at all.

Any thoughts? I've kept the phone completely stock for the moment. Removed all widgets and it's running the latest Android 4.0 that came with the phone.

I know the SGS2 isn't a top end device these days, but should I have these issues on a brand new device? Could touchwiz be causing the intermittent non-responsive feeling?

Cheers. Fair enough. Just thought I'd ask in case someone knew of a current bug / issue on the stock rom.

I'll pop back tomorrow morning and see what they say. Phone seems ok, just weird to have those very occasional battery warnings and interface lags massively (but again intermittent). Hope I can reproduce in store.

You could check if Samsung has released a update using Kies

Hmm, I think it's screwed. 5 swipes to push the notification bar up. Bummer.

Are you using the Samsung power supply? Some third-party power supplies can interfere with the touchscreen through high-frequency noise in the output.

Hi numfarr,

I am using the Samsung power supply. Although, now that you mention it, I only had the battery disconnected warnings while charging via USB (with a samsung usb cable).

So far, no warnings using the Samsung charger. Perhaps then it is related to power source as you mentioned.

Strangely enough... now testing further. The touch screen also is responsive when not plugged in.

So while charging there appears to be some issue.. not sure if I should be concerned if it only happens while charging.

I had the HF noise problem (dodgy touchscreen input) with my SGS2 and desktop PC at home before replacing the rubbish case-manufacturer power supply with a nice Enermax.

I think there is actually a mention in the manual that using the phone while charging reduces the sensitivity of the touchscreen (read: makes it pretty much unusable).

It's a fairly well known issue that the touch screen sensitivity is reduced when plugged into the charger. A number of custom firmware solutions have tweaks to the kernel to increase the sensitivity when on charger in order to work around this issue.

The battery disconnected error is most certainly not normal. I've not seen it once on my SGSII, and mine arrived in the country only a week or 2 after the original UK launch.

Thanks for the replies.

I went back to the store as the battery disconnected errors kept appearing, even with wall plug charger and any other charger I tried.

They didn't have any replacements available, so I had to take a refund.
