[Q] Lenovo A7 (A3500) / A8 (A5500) digitizer issue? - Lenovo A3500 Questions & Answers

Sorry to hijack an A3000 sub-forum with what appears to be an issue on A3500/A5500 Lenovo tablets, but seeing that there is no other place to post this I decided to go ahead and do so here. If the admins chose so, please move to a more relevant sub-thread. Please bear with me as I describe the issue below...
So I bought this A5500 the other day and was immediately confronted with what -as found at a later stage- appears to be a widespread issue on Lenovo's A3500/A5500 tablets. The issue is quite easy to replicate and is clearly evident when scrolling through a page with the finger in direct and constant touch to the screen. In this case the flow is jumpy and non-continuous as shown in the video below.
Link inserted here, however since I'm a new member I'm not allowed to attach as an external link, hopefully pasting as text link is allowed, however functionality is obviously hindered somewhat...Sorry about that, nothing I can do on my front. Please remove respective spaces from the link below to view the video, thanks.

What strikes me most is that I couldn't find any mention of the issue anywhere on the internet, seeing that it has obvious knock-on effects even on sketching a simple vertical line as shown above. So this happens only on the vertical axis, on almost all of the Lenovo A3500/A5500 devices I could get my hands on, even on the display / demo units found on major retail stores in the vicinity of where I live (South Europe). And I say almost, since apparently A7500s (A10s - 10'') models DON'T exhibit said behavior, which is ALSO the case with most other branded tablets I managed to test, either LG, Asus etc...
So my question would be if this is a known-issue for these devices, or something's gone horribly wrong with the digitizer panel of specific batches of these and need to be replaced by the manufacturer...In either case if you happen to be the owner of one such tablet, please take some time to perform these tests and report back.
Thanks!

So drawing on the vertical axis appears like so...Is this normal?!

Screen Alignment and "Green Spot Issues"

Hi all. Has anyone experienced the issues sggested in the following article by the site administrator for Pocket PC Addict? It indicates that early produced units had screen alignment issues, and some had a green spot on the screen.
[http://www.pocketpcaddict.com/forum...4-current-issues-htc-tytn-aka-htc-hermes.html
Also can those that have purchased in the US also advise whether they have units with serial numbers above HT 631xxxxx. The article suggests that these problems are not evident in units above this serial number.
Thanks.
Supposedly some have. I haventh had any problems myself.
There are a few problems post on the general forums.
Very easy to find using the search function......
Thanks for the reply and I have seen those posts. I am really interested to find out whether serial numbers higher than 630xxxxx have made it to the USA yet. Naturally only members in the USA are likely to be able to answer that.
Have a great day.
Does anyone know what form these alignment issues take, in detail? I have a UK Vodafone v1605 which has the serial number HT626XXXXX and I can reproduce screen alignment issues by turning on clear type, and trying to scroll through the list using the scroll bar in the remove programs applet.

There was a video on youtube or on google or somewhere, I forget.
But on the video person demonstrated the aligment issue by tapping a letter on the virtual keyboard, every so often the keyboard showed the letter next to the letter he was pressing to be pressed. Confusing, but I hope you get the idea.
Video is here:

Not a green spot on the screen...
The "Green spot" means a newer series of devices that have a round green sticker on (i think the bottom of) the box. Supposedly screen alignment issues on these devices are rare.
i have the 628 and jusst started experienceing this problem in the last 2 days for some reason. within that time ive noticed the device freezing and locking up as well. wtf
Yep, that's exactly the issue I have been seeing, except mine is consistent. The guy on the video was getting the misalignment every 5/6 presses whereas mine was everytime. I've noticed in my case that it's much worse with clear type on as well.
All interesting comments. The reference to the "Green Spot" in the URL I posted to start this thread actually refers to "a splotch of green from the screen", so that to me does not sound like "a green sticker" as suggested by Stefan above. I might be wrong though.
Of three suppliers that I have called none have confirmed that they have any units with Serial numbers above HT 630xxxx, and some have gone so far as to state that HTC have not made any units with S/N above that number. Can anyone else comment on that?
The article suggests that these HT 630xxxx devices were supplied as replacements to the asian users with issues.

Here's a picture of the Green Spot I thought it was all about....:
http://www.tytn.info/wiki/images/0/0d/Little_green_spot.jpg
I guess it all in the way one reads the article, and I suspect that the author's first language is not English. However it reads:
"And we also found devices with S/N after HT630XXXXX.... would be better. Since we believe they are the "real new ones", and S/N before that, just "rework" ones. The firs bunch of "guinea pigs" in Taiwan got S/N HT624 & HT625, which might have serious alignment problem. Then HTC started to release the "little green spot" version, which has S/N HT630, for changing."
The first sentence appears to indicate units with S/N "after" HT630 are recommended. It maybe that these were supplied as replacements, but I'm not sure it actually says that. The English is a little difficult to interpret on whether S/N 630 is considered fine.
I have read that HTC did actualy admit to problems with the originally released units, so I'm certainly leaning towards waiting to purchase until a supplier can confirm the S/N is above 630.
yep, but i've read some opinions about devices with sn 630xxxx that do have problems too. i have sn627xxxxx and have no problems so far.
there is a bit of luck involved when you buy one.
More than likely there's an issue with all the devices but it's only apparent with a certain cocktail of applications or uses.
The Vario II and M3100 have only been out for days, so I feel that this is clouding the issue and it is correct that this is likely a generic issue.
My TyTN has a serial starting with HT630XXX and I see the problem intermittently as well...
For what it's worth, I've had a 626 for 2 weeks and haven't had any screen alignment issues as yet...
[crosses fingers, touches wood, rubs a rabbit's paw etc]
Must admit since reducing my today plugins to the minimum and assigning the close button from Pocket Plus to the Voice Speed dial button, the device has been rock solid and very responsive! 8)
I'm now wondering if the issues are due to people not closing down their apps correctly. The reason I say this is when I installed O2 plus this morning the screen simply refused to align. I was on the screen alignment utility for four attempts prior to aligning.
Could anyone who has issues with alignment state if they use a proper close app like the one from SPB Pocket Plus or Magic button or just use the OK button?
Hi, I am experiencing the same screen alignement issues on my 4 day HTC TyTN. This seems to be a general bug.
My serial number is HT628....
The question is: is it hardware, or firmware problem?
BR,
Joe

The exaggerated, sluggish auto-brightness when recording video is an issue. Watch any of the sample videos on YouTube.
HTCsense.com issues not fixed
In Denmark, there are still problems with HTCsense.com - I mess with it to check stability and MANY times I can not connect to my phone to call it, and the SMS service takes a LONG time to react. Also, I have not yet succeeded in remotely locking the phone.
in the very first batch there was (there still is on mine) a problem where i can not use wifi it turns it self off automatically after saying "Unable to scan for networks"
ill try and grab you some debug logs so you guys are more familiar with the problem.
Internal noisereduction is too strong and it makes all photos look like they are waterpaintings, it should be a quick and easy fix for HTC to take care of.
Image sharpening is too strong set at default zero setting, you have to tune it down to get acceptable shots with less sharpening artifacts in them.
Display powerconsumption is ridicously high, it's somthing HTC have to tune in software if possible.
Possibly too strong antialiasing filter contributing to render soft photos.
/ Magnus
HTC Sense is still not working for me...the dashboard doesn't identify my phone's location, the phone does not ring, nor can it be locked or erased. Push messages from the Hub is also not working (HTC Hub via the phone allows me to browse and operate but continues to report that the server is down). The phone number I'm using and related passwords are all correct.
(I'm in Australia).
Im in denmark aswell and have no problems with htcsense.com - perfect sync and responsetime. I had a problem with the updated YouTube app, had the network error many people experienced - but got around it. But after playing a video the hd started lagging like hell.. needed reboot
Sent from my Desire HD using XDA App
I have one to add to the list:
Reduced or loss of GSM/3G/WiFi signal when your hand covers the SIM/MicroSD and/or battery cap.
P.S.
Let's make this list as complete as possible, so we can all point these issues to the HTC customer service.
Will keep an eye on this one!

I have to thank you for having the courage to do this thread, honestly im tired of the spam fest of doubled threads in this forum just because people dont use the damned search button, every damned time i come here theres 20 more threads with questions that people answered...
I suggest this for sticky!
An issue I am having is:
I will connect my phone to wifi it will connect fine and tell me I am connected.
I could then later on go into the market and try download something I will have wifi bars but the item will pause download. I then come back out to check if my wifi is still connected and it will say authenticating but doesnt change so I then turn the wifi off and back on. It connects again this time when I go back into the market to download something it works fine.
Anyone else have this issue?

I have a link that you can add below the speaker problem:
http://forum.xda-developers.com/showthread.php?p=9119804
This thread contains a comparison video, comparing the N95 vs. Desire HD external speaker quality. Also, a few posts down there I explain my experiences about the comparison.
Also, THE SIM/MicroSD cover issue IS NOT RESOLVED!
Some people had covers that stuck out a bit, but could be solved by attaching the cover properly. However, some people like me have the following problem:
When the hardware got inserted into the aluminum body from the bottom-side, it wasn't inserted far enough, causing the following 3 additional symptoms:
-Gap between top of the screen and aluminum body.
-Gap between SIM/MicroSD cover and aluminum body.
-Camera misalignment - Camera is too low behind the lens.
All these symptoms are caused by the hardware installation process, as it is clear that both gaps are exactly the same (about 0.5-0.7mm). The same counts for the camera, it has the same misalignment in mm's.
To be clear: in my case, the SIM/MicroSD cover gap is caused because the hardware is not pushed far enough into the aluminum body, thus sticking outside too far out of the alu body, and making it impossible to get a proper fit simply because it's physically impossible. It also perfectly explains the gap between the top of the screen and the alu body.
The symptoms clearly all connect to the source of the problem: hardware not inserted far enough into the alu body.
I've made a video for showing the gaps, but it's not perfect. The camera misalignment is only visible if you look closely, because the shade covers the misalignment up.

I really don't know, I'm in contact with the HTC escalation team about this, but I do hope so.
I'd be interested in any reply you get because I'm noticing the gaps now I'm looking for them and know what to look for. It's irritating because I hate swapping things but if dust gets in it could cause a lot of problems.

no problem that's the purpose of the thread anyway. I am bored of seeing people asking for the same thing all the time too.
Not sur eif anyone else is getting this, i've got like 12 bookmarks on the bookmark widget and although it's not too bad, it is quite laggy compared to the rest of the phone when you scroll through them ?
Also i've noticed some small gaps around the phone, theres one around the screen i think where a little bit of dust has got into the cracks but nothing has gone through to the screen as of yet, i've only had it for a little over a week ! not happy with this.

Shaky/crazy touch sensitivity

Hi guys, first post.
Would first like to say that this forum has been really helpful for anything Android related as I always end up on it from googling.
Anyway, after having said that I google, I could not find anyone here with this similar problem I have. At least, I'm not sure how to describe it, but I've made a video.
My touch screen's sensitivity goes haywire sometimes. It's worse on the right side of the screen, and nearly non-existent on the left.
It is virtually eliminated by a simple screen off/screen on, but starts to happen randomly later.
Makes me wonder if it's software related? Though since no one else is experiencing it as far as I've googled, I'm thinking it's hardware but I really hope not.
Anyway, here's some youtube video (just add the youtube URL at the beginning; can't post links since I'm a new user). It's most evident when I'm trying to move large widgets. You'll see me try to either hold the widget still or drag it around, which result in erratic movement/touch-releases/home screen changes. The second one is worse:
/watch?v=blYGFpqmssw
/watch?v=riAbRBLLNOM
I really don't want the hassle of returning and playing a gamble considering all the fiasco there is with lifted screens and what not; everything is fine, no dead pixels, and this isn't that of a major problem. I bought this at a local Walmart and have until the 18th till my 14 days are over; after that it's ASUS warranty. I was thinking of just bearing with this since it's minor and arrange a warranty service once craziness ends later in the year but I'm not sure how that'll go either.
Also, if someone else has or knows of this kind of problem, can you kindly redirect me? Since this problem is hard to explain in words, it's also hard to google it.

I have the exact same issue. My first Nexus was fine but I had the issue of only one channel on the headphone jack. Didn't matter how hard I pushed in the plug. The replacement jumps all over the place a reboot seems to help for a bit so I don't know that it is hardware but a wipe of the device didn't help.
---------- Post added at 01:22 PM ---------- Previous post was at 12:46 PM ----------
For what it is worth, I just called Google and they are going to send me a new one. The lady that assisted me stated that she has had a few complaints with this issue and that they just replace it. N7 #3 should be on the way in a couple days. For some reason she said that the device wasn't set up properly in my profile so it will add a couple days to the process because of the long weekend.
Not a big deal. I have lived with it for a while now. At least they appear to be taking care of it and I wasn't transferred to Asus. At least yet.

[Q] Are Note 7 Touch-Screen Issues Hardware or Software?

Hi guys,
I recently purchased a used Tegra Note 7 on eBay. As I'm in the UK it's the Advent Vega variety, although I don't know if that is relevant as they all appear to be the same unit; can someone confirm?
Anyway, I have noticed that every so often I lose touch response along the left or bottom edge of the screen, where the nav-bar would be in either portrait or landscape modes. This sometimes results in me having difficulty pressing the back or home button, or having difficulty selecting the settings button in the bundled camera app (this sits at the top-left of the screen). Another annoyance I found in the YouTube app; when scrolling through videos to watch, it would load the first video my finger landed on, but then continue scrolling. It's like it registers my first touch as a 'click' then realises I actually want to perform a continuous movement.
Having read a few posts scattered across the net about various touch-screen issues and some apparent software fixes, I wonder if I should stick with the tablet and wait for Lollipop to fix everything(!), or send it back on the assumption that this is an inherent fault. Because I may end up sending the tablet back, I'm hesitant to try any software fixes that require unlocking the bootloader and installing a custom recovery.
So what is the general consensus? Is the hardware flaky on these devices, or is software to blame?
I wasn't pleased when I found out that the UK models are Advent Vega (I experienced many issues with their first budget device, which was pretty horrible), but hoped all Tegra Notes were built equally regardless of the market.
Thanks in advance.
Today I was watching YouTube in reverse-landscape mode (so that the hinge on the flip case was at the top), and I couldn't click the search button at the top right of the app. It just would not register. Five minutes later, it starts working.
What's the deal with these screens?
Well, it's going back to the seller. I had no confidence in the device being able to give me hassle-free use throughout its life.
Plus there doesn't seem to be much of a community. Weird how this tablet seems to have gone under the radar.
HELLO-O-O-o-o-? ECHO-O-O-o-o-.
I get the touch screen issues occasionally too. I find that just turning the screen off and then back on usually fixes the issue.
Still it is bloody irritating!
I am miffed at the lack of community support for this device too. I thought that given the price and the fact that unlocking the bootloader is so easy that the dev community would have been all over this tablet. Shame.
Yeah it's a strange one for sure. It's still one of the most powerful tablets around, runs almost pure Android, has front-facing speakers, a half-decent stylus, easy to unlock like you say, and is an absolute bargain.
The Shield Tablet looks absolutely awesome though, hopefully that ends up with more of a following.

[Q] Lenovo A10-70 (A7600-F) 'random click' issue

Hi,
I’ve created similar post also on the official Lenovo forum but from my point of view it is also worth-asking you guys here.
I would like to ask you for help / idea. We bought Lenovo A10-70 (A7600-F) ~ 6 months ago and after just few days we encountered quite ‘weird’ behavior – random clicks on the screen.
I was trying to solve the issue using just common things like: Android updates (official ones) and factory reset. Unfortunately the issue still persist.
We asked authorized service for fixing the tablet for the first time and we’ve received it back with following ‘repair method / information’:
“We made a new device settings (lead wire).”
Unfortunately the issue still persist..
The second try (in another authorized service – Arvato in Czech Republic) was declined as “not repro / sw issue”.
Basically, as you can see below the issue is about ‘random clicking’ on the screen.
It is happening on completely random basis (once a day, many times in a day), usually on the right / left corner of the touch screen. It is happening in many games and also in Android itself (visible on the second video).
All videos were captured in HayDay game only due to I lost my armies (in other games) several times before (you know, it makes not a such difference when some crops are harvested rather than all army is attacking e.g. right top corner – maybe there were some cool trees and rocks).
I cannot see similar issue on other devices (and the same games), e.g. Samsung tablet GT-N8010, Huawei cell phone Y550, Lenovo tablet Yoga 2.
Do you have please any idea how to fix it / what is the cause?

Any ideal pls?
Any idea please?

Thanks a lot for any feedback / opinion!
