strange behavior while plugged in

[cirko]

Hi,

my X1 compact shows a strange behavior since yesterday:

I plugged it in via the USB port for charging, and it started doing crazy things. Screen brightness went flashing from low to high and back, the touchscreen showed slow or no response to pushing buttons, everything got laggy as if some kind of process was running in the background with no end. When I unplug it, it basically works normally. But - from this time on, I couldn't charge it anymore, as the charge went down instead of up when plugged in! I tried a factory reset several times (power + volume up for 3 seconds), and although it did reset, the charging problem remained. I left it turned off for one night while plugged in, and in the morning, it was just charged to 25% with the charge going down rapidly in the first couple of minutes (after 5 minutes to 11%). Now it's at 1%, but I can use it for quite a while, indicating that the displayed charge certainly isn't correct.

When I plug it in, the same things happen again and again. When plugged in, I can't even enter the PIN correctly, because touchscreen input is somehow recognized falsely.

What could that be, what could I do??

I also noticed that there seems to be a slack joint when plugging in the USB charger, although I haven't noticed that before. Anyway, I now sent it to service and hope for better times.

Thanks,

According to the report I already received from the service center, several parts have been replaced:

-mainboard

-part of the case

-"small parts"

-wifi-antenna

Hmm, seems pretty much to me that they gutted the phone and replaced everything in there. Is it worth it? Well, anyway, I hope it's going to work when I get it back.

It should be worth it but it is better to wait and see.

OK, now that the testing is through, I can say that it now works as it should, no more strange behaviour. Well where should it come from anyway, the whole mainboard is new!

But - the first time I tried to charge it via the sony docking station, it again lost charge instead of gaining! I feared that it's the same issue again, and did a hard reset and charged via USB again. As it charged normally, i tried it again in the dock in a later cycle and since then it works like it should. Let's hope there's not going to be charging issues anymore. Seems like teething troubles of the z1 compact anyway.

So long,

Aleks

I am kind of happy for you but test it for a couple of days and see.
