Issue with the touch screen

[Guest fremar]

Think that the touchscreen is broken or something on my San Francisco. It behaves really strange and works for a while and then it starts to register touches all over the screen. Tried app, touch test and if I touch the screen and hold the finger there it suddenly pops up to spots that jumps around on the screen irraticly. When I lift my finger away from the screen the dots are still on the screen and wont go away before I shut the screen off and the on again. Dont now what to do now really :lol: Have tried to do a reset of userdata and cache but no change.

Sound's like you need to exchange it for another one ASAP.

[Guest Rem1x]

I've had that one or twice while playing PacMan Championship Edition. It's rather weird.

[Guest Simon O]

Does sound like you have a bad digitizer. Replace the phone.

[Guest fremar]

Yes going to send it back to uk to get it replaced

[Guest David Horvath]

I have the same "problem", i still have the screen protector, will remove that and test it. It would be really hard to replace it from Hungary :/ Hope it will be fine.

I have a similar problem, although its quite random. The touchscreen stops registering touches. I've found that removing the back of the case solves it everytime.

Yeah I get the same, goes completely unusable and I have to reset it by removing the battery

the weird thing is that i don't have to reset, when the back is removed the touchscreen starts working again.

[Guest R_A_V]

My San Francisco acts like this too. Don't know what to do. I've tried modaco r4 rom, froyo alfa rom, original one. Issue remains.

Could anybody help me and answer:

1. Is it possible to exchange SF if I havn't really bought it in Orange? I've bought it on eBay. Any warranty possible for me?

2. Does Orange admit international shipping? If I return a phone to them directly could they send an exchanged one back?

3. Maybe someone in UK could help me to exchange it?

Thanks in advance.

Looks like the same problem that my first SF had. Try to install "Multitouch Vis Test" then you can see whats going on, mine worked as it should if I just barely touched the screen. But if I pressed just a little bit harder it went crazy, turning the screen off and then on again made it work again until it was pressed to hard again. Sent it back to UK and the seller replaced it for me and then tested the new phone so all was good with it.

[Guest qylin]

Sorry to hear that, mine is on shipping, hope it doesn't have such issue, as it's pretty hard to exchange it in China.

It seems touch screen is the most vulernable device, my iTouch was repaired for the same reason - touch screen failure, that no matter how you try to register a touch, it doesn't.

Thanks for a hint. Installed "Multitouch Visual Test" and found that where is a "bad" area on the touch screen (about 1/5 of screen). If I press a bit harder in this area touch screen goes crazy. Now I know exactly that it's a hardware issue.

I'm not sure when it started acting like this. I mean I don't know if it came to me faulty or it's my fault (maybe I pressed it too hard and broke it).

You are right and Its true No wonder from Chinese Design and manufactorer plus cheapest price ever, what we can expect? look like they spend least time on Product Testing, more than 65% of user facing some kind of major hardware or performace related issue, look like Paul's review? and hotukdeals.com post help boost the SF sell otherwise no one even try to know even look. the great Indian said 'The person who buy cheap things cry everyday but quality buyer cry only once (at the time of paid money)' its really true in the case of SF

but before we go to buy for cheaper things 1st things not to expect great expectation of the things or device

how is your personal experience with the SF? is your main device?

my one main device is Iphone 3gs since last December and since than I used/buy Samsung omnia (sold), Nokia 5800(sold), LG Gt540 very impressive, not high resolutiuon as SF wuth no sensor but Decent Camera, Extremly fast graphics performance very stable unlike SF, I impress review by Paud and sell it and buy SF but I must say the graphics and overall speed and bettery life and build quality is outstanding on LG gt540

get it touch with u

No one had a gun at you to force you to buy a CHEAP device manufactured by Chinese, and the Chinese manufacture has been nortorious for its cheap price and low quality for a long time. You've made your own decision-to buy SF- you should have response for your own decision. Maybe you won't buy Chineses product, that's ok, but somebody out there might, because they are cheap enough. So if you just wanna to "Cry only for once" go and get a Jab brand.

Besides, I'm quite curious on where have you gotten the statistic 65%?

By the way, my apple gadget, iTouch, from Apple, well known for its solid quality, has failed just because the same reason-touch screen. And due to my occupation, I happen to experience some kinds of smart phones, they are not impeachable as well:

iPhone 4: signal loss when gripped a certain way

Motorola Milestone: main board failure, the usb connector had some issues

X10: with rom 1.6, poorly support opengl, all the graphics are jams

Nexus One: screen fatigue - some points of the display is color matched

Could you please clean you PM box. I have a message for you.

I've got the same problem if I pressed too hard in the area of the screen to the left of the volume buttons the screen goes crazy. If I press the power button twice (so the screen locks and comes back) the touchscreen works a little bit better - but multitouch visible test shows up some tracking issues. If I reboot the phone it all works fine again.

So did you just admit that chinese cheap devices = bad devices?

Also I didn't see anyone blaming China or Chinese for the faulty digitiser so why don't you relax?

[Guest d4m4n]

Looks like my Blade is FOA (Faulty On Arrival).

The touchscreen goes crazy after few minutes of use.

Sliding a picture or map makes it zoom in or out.

While typing letters I get extra letter from the opposite side of the keyboard. This effect is clearly visible with swype. I can see blue swipe lines even if I'm not touching the screen.

Icons and images may vibrate on the screen after I move them.

Looks like the same problem as others on this thread.

This phone is quite useless so I'll return it for repair/replacement tomorrow. The model is Saunalahti TFT.

[Guest Oyorf]

I have sometimes same problem. Sometimes display goes just crazy and it's like there is touches everywhere. And sometimes when I try to use google map and move on the map with one finger, phone thinks i'm zooming and so on. This does not happen very often and it goes away if i "twist" the phone little bit.

That's what I'm seeing. Interesting thread.

Squeezing the top right seems to cure it for me, and squeezing the top left sometimes breaks it again. Twisting the phone has a similar effect.

There seem to be a few modes depending on where it is twisted:

- not responding to any touch

- taking single touches as a multitouch with an invisible finger mirrored down the vertical axis

- jumping single touch around a bit

- working fine

Given this looks like a problem with a physical connection breaking continuity, it's very tempting to take it apart for a look. It's a shame one of the screws has tamper detection.

Curiously, I read a thread where a chap took his apart to repaint the case and claims he did this very carefully without damaging any connectors - but on reassembly the touchscreen didn't work. It would appear there is something particularly sensitive about a connector somewhere.

This problem only started manifesting on my phone yesterday after about a month of careful ownership.

The wife's San Fran (which she's had longer) is fine, however.

Can anyone see from this teardown/rebuild video of the ZTE Blade where the touchscreen connector is?

[Guest scoobydoo99]

Can anyone see from this teardown/rebuild video of the ZTE Blade where the touchscreen connector is?

I'd guess it the one at the top left, if you watch the video, at about 4 min 40 secs, when he's reassembling, he seems to have a problem getting it to fire up. He checks the battery connections a couple of times, that doesn't seem to work so he then fiddles with ribbon connector on the top left. I'm guessing the phone was starting when he was trying it, but the screen connector wasn't quite fully home?

[Guest tttonyyy]

Could be. Fixing the touchscreen issues might just be a case of wiggling or disconnecting and reconnecting that ribbon connector.
