Check your Lumia 620 screen.

I agree it does seem more like a grounding issue which would probably rule out a firmware update to fix? I can imagine they are either all like this and no one has noticed or there is a large batch that have this issue.

I have posted on the Nokia forums too see if Nokia reply or not although I imagine not. lol

I've contacted Nokia Care twitter account about multitouch problem of my Lumia 620.
They first suggested me to do a soft reset, and then a hard reset. But problem didn't solve.
Finally, they said: "Given the scenario, it's best to have the device checked at the repair facility or check with your retailer for return policy ^EP"
...

Update: Today, two fingers are also working correctly on my phone. But it fails with 3 or more fingers.

I checked the multi touch on my phone before I sent it back for another issue. It could register 4 points and could briefly register 5 before it flicked to zero. Even with two points it was slightly shaky.

That being said, I wouldn't have known about the issue if I hadn't checked. I had no issues with zooming on webpages/ photos or gaming etc. with general phone usage.

Exactly, but only some time where my phone is completely useless when it affect the functionality of the screen. When it does, I have to lock and unlock the screen. Solved it for a couple of minutes, but it happened again. Strangely, it only happen on Tuesday and since today is Tuesday, I'm pretty much prepared to face it

I get 4 points. Some juddering on our 620 when pinching and zooming but I assume that is the processor struggling to render. Doesn't seem to affect functionality or usability.

Interesting. I've got ten on my Nokia Lumia 920, only five on my HTC titan. This is very interesting.

This occurred 2 or 3 times on mine, and I hadn't this issue after hard resetting my phone. (from settings menu)

I have been chatting to Nokia Care on Twitter and they say they have pushed out an update for all WP8 devices and that I should wait for that however they cant confirm when it will available or if it will fix the multitouch issue.

I am going to contact O2 and arrange a replacement unless the update gets here first and resolves it as they are out of stock at the moment.

Are you able to test it outside of these diagnostic apps? Is there any way to test it in real-world usage?

Mine is having issue even with two point multi-touch, so games (e.g. Gun Bros, Toy Solider) will show you the "effect".

 

[pengfoong]

Wow, I had very few replies back then when I started the topic. Didn't know that many people are experiencing the same problem.

I've sent my 620 to the Nokia Care. They are taking their own sweet time to fix the problem.

Yes. I noticed strange behaviors while playing games. After that I downloaded the test to verify my suspicion.

It happens to me even when it is two points. This means I could not even pinch and zoom. LOL

Hopefully they'll provide you with a report detailing steps taken to resolve the problem.

Don't think that is going to happen. They initially said I need to wait for two weeks. It's the fifth week now. This is even after I've escalated the case. Nokia has very horrible customer service here.

 

[John Bourne]

It seems the new firmware (1030.5603.1304.0002) does not resolve the multitouch issue.

Nokia Care have suggested I take it in for repair or return it to point of purchase, I imagine a replacment may possibly have the same issue but worth a shot.

 

[pengfoong]

Because different people from different geographical areas are affected by this issue, I think this affects quite a number of units. I've tipped wpcentral about this issue. If they post about this issue, maybe more people would be able to check their units. Potential buyers can check their units too before paying and going home with it.

There seems to be another possible "Hardware" issue with 620's. Check your speaker:

Me too, they also said two to three weeks, but the engineer obviously didn't know the issue. After around two weeks, they told me the problem was fixed. but it did not. They then told me to wait again for their investigation.

Me too, they also said two to three weeks, but the engineer obviously didn't know the issue. After around two weeks, they told me the software was updated and the screen was tuned. So I went to verified but the problem is still there. And then they replaced the touch panel with a new one, but it did not work out either. They told me to wait again for their investigation.

Where are you from? The technicians in my country (Malaysia) said the same thing after weeks. They told me the problem was fixed after the software was upgraded. I went there and the problem was still there. They are waiting for a new touch panel now. LOL

 

[pengfoong]

jack00, this is almost certainly a hardware issue. If you plug in the charging cable and hold the other end with your fingers, multi touch works. in both cases, it is not charging. I hope that wpcentral write an article about this issue. Many people would have missed this problem.

How did you get that update? Mine is 1030.5603.1250.0002 , and settings menu says that my phone is up do date :eck:
