Charging = awful touch screen experience?

25 posts in this topic

Posted (edited) · Report post

Hi there!

I've purchased the ZTE Blade III a couple of days ago. So far it seems to be running very well, speed isn't really much of an issue.

What bothers me though, is that the touch-screen gets VERY sluggish/unresponsive when I connect a charger to the phone.

Every time I charge it, I have to restart the phone, in order to get the touchscreen to work normally again.

Any help would be appreciated!

Greetings,

M. Angelov

EDIT:Turns out I don't have to reboot the phone in order to get the screen working normally again. I tried unplugging the charger right now and the problem seems to disappear.

I guess the main question is: faulty software, or faulty hardware?

Are you by any chance running a custom ROM?

I'm on stock 4.0.4 and I wonder if people with custom ROMs also experience the same problem.

Guess it's time for me to flash it, eh?

I'll look up some builds and post up here if my problem is solved.

Meanwhile; can anyone else w/ a custom ROM (other than the Aurora build) confirm the problem doesn't persist on their Blade 3s?

Uh, that sounds bad.

I hope no damages are done to the hardware over time.

Probable cause, anyone?

A small addition; problem doesn't seem to be persisting, while charging the cellphone off a USB port

I've had this issue with various phones when using cheap 3rd party chargers. Sometimes the screen stops responding completely while plugged in. From what I've gathered if the charger is badly made the current it supplies can be "dirty" and cause interference with the touchscreen. Try a different/official charger,

The problem is persisting only on the official charger as far as I'm aware.

Yeah, I wonder if we can get our chargers replaced if we notify the company they're shipping bad ones.

If not - what charger does your brother use? I'm up for buying one too, if ZTE don't make a 2nd, working rev. of the current ones.

The problem is not in the cable its in the charger.The phone works fine when charging with pc or other charger but with the official not,or at least for some.I think that this is the same as the rebooting problem some of the other blade 3's have,just not as big as it.

Im still using my cable for charging btw.

Another issue; When you're on a white/gray page you can clearly see rows of vertical pixels on the screen.

The rows are equally spaced at about 0,3cm from each other.

It's very notable when you're using the green wallpaper the phone comes with (last one from the selection).

You have to be close-ish to the screen and tilt it a little bit in order to notice it.

Am I alone on this one, or do you guys have it too?

A small clarification edit; they're dot-alike.

Charger provided with blade gives only 0,7A output, chargers giveing 1A output solve the problem.

Why doesn't the problem persist, while the phone is being charged via an USB port then?

USB outputs 500mA, which is even less than the charger's amperage, thus this doesn't make sense.

So I'm not the only one?

Charger outputs "dirty " current that causes interference with touch screen.

Yes matrix can be seen on all devices, something similar can be seen on SE phones when turned off or on black background against sunlight.

Thanks for shining some light on the "issue", I really appreciate it!

Looks like I'll need a new charger, which kinda bums me out, but other than that, the Blade III is a pretty solid phone so far.

Oh yes, and I have the same problem with the Blade III when using the original charger it's been shipped with. But no problem when charging with the old one left from the Blade I, despite both chargers looking essentially the same.

Guess I should look around for a Blade I charger then. The battery recharges twice as long when connected to a PC, so yeah, having a charger is a must.

Btw, my good charger says "Made in China by Dokocom" just beneath the barcode on the label. The newer and bad one is "Made in China by Ruide".
