Slowdown Touch in AC Charge

I noticed when i put to charge my RAZR I with its AC power supply, there is a strange effect on the touch screen. My phone dont responds well, the problem in touchscreen when i roll up the menus, the programs nd browser is ok but the menus dont work fluid. The problem only happens when i charge in AC. In Usb(PC) doesnt have problem.
Is it normal? am i having a problem?
Thx

anybody?

yes, I also noticed that. But its not always. This may be caused by the cahrger or the socket itself, if there are other devices plugged in as well. Touchscreens do react very fast on any kind of unnormal powersupply. I have 3 of those original Motorola wall chargers. but i noticed that only on one of those. maybe its the socket where it is plugged in or the charger itself. i will test is later while recharging my phone.

I noticed this for the first time today. Very strange. And annoying.

I change my charge for another but LG. Same problem. My city is 220v is not 110v.

I know if was more of a common issue on older phones..... perhaps this lovely problem is back with the Intel chips.

Speaking from older Samsung phones. But I assume it was common. Some of my old HTC phones had the same problem.

What firmware version have you ?
I upgraded mine with latest EU firmware here:
http://forum.xda-developers.com/showthread.php?t=1936512
My Razr was not up to date.
Not a big update but I noticed some improvement: No more lag when zooming out/in the home page, NFC notification get an icon near the clock, before it was a " standard app notification".
I never notice the sluggish touchscreen, maybe this issue is solved on this firmware.

The last version. I update in the last week. FW: Brazilian version 87111012012.XT890

I've had this problem on a number of Motorola phones (and others) and believe it's something to do with earthing/grounding. That could be why it varies from one charger to another, or even perhaps how much current is flowing through the charger.
I'm not an electrical expert, so I might be talking nonsense - but I don't think it will be firmware related.

there are problem with charger or is my house? Here is 220 volts.

So finally i got my battery empty after 2,5 Days
Just tested it with my old charger from a Mielstone 2 and the new one.
There is no lag or slowdown with the new one, but with my old charger the phone reacts very bad especially to light touch gestures. So i guess its a problem with the AC charger. I have 230V here in Germany. Or the Touchscreen (digitizer) is just too cheap and can't handle a non perfect Current/Voltage.

I tested with diferent charger and same problem. I pick up a Samsung SII and some problem with my chargr and I use anothers charge with Samsung II same problem too. I have a LG P500 and dont have problem. Whats happens? Samsung SII and Razr I there are delay in touch but LG P500 I dont have this problem USB never problem.

[Q] LT30p not charging or connectin using old HTC microUSB cables

Hello all,
so, this is driving me nuts. I have two HTC microUSB cables that I've been using with my old phone that for some reason don't seem to work at all with the new xperia T. I can only charge it and connect it using the stock sony cable or the (very long) cable that came with my Kindle. I tried with 3 different wall chargers (Sony, LG and generic wall outlet splitter with USB): all of them charge the phone using Sony and Kindle cable, none using the HTC cables. Anyone has any idea WTF is happening?
Thanks!

Based on my friend's experience, HTC tends to make cables that work only for their device. I'm not 100% sure.
Humans have evolved to be smarter, but there's one thing we can't get rid off. It's human stupidity.

I think there are different versions of the cable, if you take a close look at the end which goes into your phone you may be able to count a different number of connections....
Someone correct me if I am wrong

I'm charging my lt30p atm with the cable that came with my HTC desire S. Also connecting with pc is not a problem hetr

Well, both cables used to charge also my LG p500 without any issue. I'd be more inclined to say that the fault is on Sony's side as of now.

Slightly different shape of the inner part of the connector, but same exact number of connections.

I envy you very much indeed.
So, to sum it up, it can't be anything to do with the phone itself, but it seems to be some kind of incompatibility between the USB plug and socket. This is kinda crappy. Last thing I want is to buy yet another cable. Haven't they decided to use the same standard to avoid this kind of crap???
Thnaks to all of you btw!

Just use the cable that came with the phone for PC connection and the other ones for charging...

They don't work either way. It's like they don't even connect. Point is I don't understand why. It's just a cable. Anyway, thanks for all the input.

Some cables are manufactured not to work with most phones. Just like how we can't use our plug (for the wall socket) to charge an Apple device.

My previous experience doesn't seem to comply with what you just said. I've been exchanging chargers and cables between 1 LG phone, 1 HTC phone and an iPhone 4, and all the combinations work. The problem has arisen with the new Xperia T. I'll go to a Sony center and see what they have to say about it.
Cheers!

The t/x/v have faster higher rated chargers so some old ones don't work, I can't use old 2011 Line charger or moto charger but can use an earlier v8 charger...
If you look closely at the cable there are parts that click into place, if the cable your trying hasn't got these it won't work

As I said, no matter how weak the charger is, I always get power with the sony and Amazon cable, and none with htc ones. It is really annoying. The cables don't seem to have any major physical differences.

Help! My phone isn't charging.

One day I was away from home and my battery was low. So I had to use a Sony Xperia charger. But now my phone has problems charge.
problems such as:
-it won't charge
-it only charges to 50%
-the charge cuts in and out
-I have to leave it still or it won't charge.
Has anyone had these problems occur. This is really annoying and I would like to find a solution ASAP
*and the only charger that doesn't cause this problem is ny nexus 7 charger. But I don't want to use it. Because when I tried it, it said it's not compatible and will damage my device.

Unfortunately it sounds like the micro USB connector port may be partially broken. Did you try a different USB cable with the stock charger?

If your phone is charging half way through then It should not be the connector. Try charging through the use if laptop. Try clearing the battery stats if rooted else back up your phone and try restoring it to factory settings.

HI
greetings,
I think its a hardware problem
might be the micro usb port of the cable has to do something
try any of your friends htc cable and plug and see if the problem exist then its not the cable but the phone ....
best way is to take your phone to htc service centre

[Q] Moto G 2nd Gen Touchscreen Issues while charging.

Hello everyone.
I had purchased moto g 2014 a couple a months back.Initially the device used to work flawlessly but from the past 2 weeks I have been experiencing issues with the touchscreen which dosent respond correctly while charging.It goes crazy when I hold the touch.Its been really difficult to work with the phone while charging.At around 80-90 percent is stabilizes a bit.Its dosent have any issue while off charger(ie once I unplug the wire it is still crazy but comes back to normal in a while),
I have tried to charging it with my moto charger which came along with my phone and have also tried charging with a Samsung,Sony and Nokia charger (all lower rated) but that too dosent fix the issue.I have even tried usb charging.Now those who would say the my apartments power outlets are noisy,well 4 different phones charge just fine without any issue.
I have even tried fixing this by upgrading to lollipop and then also a hard reset but both were useless.
So I really need to find a fix.Pls help.

Don't know what you are using for a charger as moto g doesn't come with a charger just a usb cable. You could always take the phone back to your supplier.

I have had bad USB cables cause this issue with other phones. Even chargers as well.
Try to use a good quality charger or if you're using a computer, a different port or computer.
I have an Anker cable with a Samsung USB wall charger I'm using and haven't had any issues, even takes a lot less time than the stock Moto G 2 charger (1200 ma vs 550ma).

It did come with a charger(atleast the Indian version did).Its a standard white charger for all variants.Its does look a bit low quality and easily gets heated while charging so that might be the source for my problem.

Same here,I have been using a Nokia charger for a couple of days now,and I have found that the screen is a lot better than while charging on my moto charger(Earlier I used to start charging with my moto charger and then switch to other charger just to check if the problem gets solved but now I tried charging it right from zero with Nokia charger).Even the phone charges faster than that on the higher rated moto charger.So i guess the problems with the charger and not my digitizer or the battery.But still I am facing the screen issue(though on a much less scale).

So, have you tried to calibrate your touchscreen when charging?

That's a common problem with many touch-screen devices while loading.
The charger and/or cable is emitting a low electrical field which interferes with the digitizer and your body's electrical field. Not much you can do about. To find a proper shielded charger and cable is pure luck.

Well shouldn't that affect all the phones?My friend moto 2014 doesn't have any of these issue even on a normal charger .Should that imply that my phone has manufacturing defect?

I don't think so. I have different devices from different Manufacturers ( 2 Motorolas, Asus, Samsung),all with different chargers. They all do misbehave while charging. Maybe it's a problem with the electrical system in the building. But I highly doubt a manufacturers error.

[Q] Scosche - Revolt 2-port USB car charger - 2 12W ports

Hi everyone,
I just bought this car charger, hoping that I could get a faster charging inside my car, as it says at Amazon (and also in the pack of the product) that it works with android phones (Motorola’s ones as well).
Unfortunately, it seems it does not work with our Nexus 6.
Has anyone own the same charger and have similar troubles?
Regards.

For our phones you need a Qualcomm certified charger that charges at 2amps 18w or higher.

Thanks,
But, despite not being a certified quick charger (Qualcomm technology) any charger should work anyhow whith the phone, right? I have myself plenty of old ones that works fine with the Nexus, but this one.

I looked the product up. And it seems some people received the 10w model. And they are having issues with charging phones that require 2.0A or higher. Maybe you should look into it. They might of sent you an older model.

I have the charger and it works fine to charge the phone. The post that states you need a Qualcomm Quick Charge certified charger is also completely false. You only need that if you want to take advantage of the fastest charging rates possible, but other chargers certainly work just fine, and I RARELY use the charger that came with my phone to charge it.

How about a bit of clarifications... does not charge AT ALL? Or charges, but slow?
If it does not charge at all, then you need to make sure that it is actually making contact with the cig lighter plug. Does the charger have a light? If so, does the light turn on? Have you tried a different USB wire? If you've tried a different wire, and can confirm that it is getting power from your cig lighter plug, and it still doesn't charge AT ALL, then your unit is defective. End of story.
If it charges, but slow, then its working as expected.

It doesn't charge at all.
Tested again with an iPad and with a blackberry and it works normally with both. It just does not works with my Nexus 6...
BTW, my Nexus 6 works with other car charges that I have (an old Samsung one and a belkin too).
