touchscreen unresponsive while dt2w/sweep2wake enabled - Lenovo A6000/Plus Questions & Answers

Hi. I come from a6020 forum. I write here because I've discovered we have a very common bug on ROMs with kernels that support dt2w/sweep2wake features.
The issue is as the title says: touchscreen won't respond after waking up from deep sleep, while having dt2w/sweep2wake features enabled.
Only the volume +/- and pwr buttons will work.
I just have to reboot the phone and the touchscreen will work again, but after a while the issue comes back.
The only way to get the phone working normal, is disabling those features from Kernel Adiutor.
I'm part of a telegram tester group for my device, but developers there can't find where the issue is.
my question here is:
Do you have a fix/workaround, other than just disabling? Or at least do you know why dt2w causes the touchscreen to bad working, specifically?
Surely, you know what I'm talking about, cause I've seen reports for this bug on some a6000 threads.
If you could response me, @dev_harsh1998, @ED300, @rohitsinha12, or @IvanHephaestus, I'll be grateful, for sure. thanks in advance.

I have same problem please help

This is seen to happen on the devices with non original vendor panel or on those panel which fail to pass the firmware check btw if that happens upload the kernel logs i will write an patch to fix the issue prolly we need a condition resched somewhere. I haven't much bothered upon fixing it on our device because its seen happening only for people with damaged or non original panels

Touch display serious problem!

Ho all,
I am having a serious problem with touch display alligning. It happened two times, on resuming it from stand by, touch screen lost its configuration. So that display becomes unusable becouse finger touch doesn't have a correct corrispondance. I had to restart device to have it working again.
Have you installed any custom ROMs? If not...
You'll want to contact HTC as this sounds like it may be a hardware issue. http://www.htc.com/www/support/nexusone/

No, I still haven't rooted it. It's with stock rom. HW problem? I wish in a SW issue..
I've seen this issue crop up on my rooted N1 as well. A reboot fixes it, as does waiting it out. For some reason I seem to notice it happening when I'm in the browser. There's a thread here about it (which evidently I can't link to since I'm new). Check the second page of the general section, the subject is "touch screen issues".
Seems like a software issue to me, but who knows.
The first thing to do if you have these types of obvious software issues is a hard reset (Settings>Privacy>Factory Reset). If that doesn't work, then it's time to call HTC.

Thank you all! I found the post where this is being discussed.
This is an issue many people are experiencing on google support forums, in fact it is the second longest thread after the 3g issues. It has also finally been pinned. Here is the link: http://www.google.com/support/forum/p/android/thread?tid=04134c63c784258e&hl=en#all
Anyone experiencing the same problem please post in that thread, the more people that post the more chance for google to acknowledge this and remedy.
BTW I also experince issues with the touch screen which happen quite randomly and can normally be cleared with a power on/off. When the screen goes bad the touch is no longer registered in the correct spot on the screen.

[REQUEST] Fix for screen-off-issue after call

Hi @ all,
i know my thread is in a wrong place but its time to give more attention to this issue which is concerning a lot of hd2-Android users.
As you all know the htc hd2 is a smartPHONE.
It's most important function is to let us make our phone calls without any trouble!
But there's a problem:
A lot of users complain about the screen staying off after having made a phone call. It doesn't turn on unless you hold the phone in a bright light. No chance for anybody who's in a darker environment at that time. Hardware keys also don't let the screen turn on again. So often the only way to solve this problem is taking out battery and reboot.
This is REALLY annoying and ashaming for all users, i mean we have one of the greatest phones for custom roms, but we can't make a proper phone call -.-
So to sum up: There are several threads already opened, with no solution and no real end.
My wish to all the great Chefs and developers out there: Thanks for your hard efforts so far.
But PLEASE try to fix this issue. Perhaps deactivating the proximity/light sensor, or just making the phone let its screen turned on during a call might be a solution?
So many roms out there with hundreds of versions but no one works for me and many others without this issue.
PERSONALLY, i don't care if my rom has ultra-spectacular-amazing quadrant score or the latest sense 3.0 shich has still bugs.
Just a stable rom for using our hd2 as a real phone, that's what so many want, so hard to understand?
Thanks, for reading.
BTW: the hint to make the proximity/light sensor clean doesn't work, and some users don't understand the scren-off issue, i know.
screen after call
I have the opposite problem - my screen remains unlocked after phone call which is a big problem when the phone is in my pocket and i'm answering with a BT device.
I usually find the phone is some strange settings screen or some app running.

There is no "but", If its in wrong place its in wrong place.
If you have this issue its likely rom related as this isn't a wide spread general issue as I have personally never experienced it.
if you want to discuss this issue reply in the appropriate roms topic, You are not a dev and not posting dev work/reference.
uhuuhu...
NO, it's NOT rom related. I think testing about 10 of the most popular roms here is enough...
Just search for it. I said it before some people don't have this problem but there are also many others who have it.
BTW: askin in the roms section was intending to get attention as wehenever yopu aks for it in the thread of the rom no one cares.
Just sad that the most "Devs" think building a rom is just abaout making it looking cool full of unnecessary special addons and customisations...

["Somebody's" CM10 & "That" rom] Bug/fix reports & newest info (26-Oct-2012)

["Somebody's" CM10 & "That" rom] Bug/fix reports & newest info (26-Oct-2012)
Firstly, I would like to give a big Thanks to "somebody" as well as the dev team at the behind of these roms for their efforts to bring ISC & JB as great things to our device.
Recently, I've tried both the ICSROM (known as the tune of leaked Rom under CWM flashable zip - Let's click Thanks for Upndwn4par) and "somebody's" CM10 (let's click Thanks for ticiano_arraes) and saw that they both have identical issues as reported by people such as the battery life, the deep sleep, the camera flash... including working fixes. But the fixes spread over the pages of threads caused inconveniences for us to track or update info. So I would like to open new thread just for purpose of collecting bug reports and the fixes from and for both users and our devs to get latest info on these roms quickly.
Admins please feel free to delete if this thread is already opened or if it's just not neccessary.
Belows are lists of great things of ICS/JB given by these roms that you can taste right now, and also the list of bugs/issues along with the best possible solutions that you can try for workaraound while waiting for the perfect release. The lists will be updated upon report from you guys. So please provide any thing from your experiences on these roms.
* Great things:
** For both roms:
+ Touch sensitivity is a big improvement in speed and accuracy (this might be inherited from Butter Project)
+ HDMI mirror works fine.
+ Others (pls share your experiences...)
** Individually for each rom:
ICSROM:
+ Webtop 3.0: work like a charm!
+ New Camera/Camcoder by Motorola with various valued upgrades such as Auto continuous (live) focus mode even for camcoder, full HD capture...
+ FingerPrint scanner @first steps of working (worked but not yet supported by original ICS/JB).
+ New valued apps added, such as Smart Actions (similar to Tasker, Locale but more intuitive/friendly/efficient), MotoPrint (valued add not only for business man but even for home usage), Battery Tracer (for battery monitoring with rich info)...
"Sombody" CM10::
+ All great things from CM10 as you experienced with such as Epinter's rom...
+ Camera/camcoder: worked.
+ 2D hardware accelerator: worked.
+ Data/GPS/Wifi/Bluetooth...: worked fine.
* Bugs/issues and workarounds (Newest update info are sized in big text, this helps you guys to track info more quickly):
1. Camera flash doesn't work properly: (Fixing is in progress...)
- Temporary solution: Turn on the torch while capturing in dark (shouldn't keep the flash on continuously over 5 min for safety of the LED flash light)
2. Deep sleep problem (which causes your phone cannot wake up upon power key pressing): CM10 23-Oct build FIXED. But some users reported that the bug is still there on their Atrix. So, the best way is that you flash and experience yourself to check whether the fix works on your device
If this problem still persists on your Atrix, try one of solutions belows:
- Solution 1 (confirmed): Remove the external SD card.
- Solution 2 (Edited: seems not worked): Turn off any screen unlocker (Choose None in Screen Unlock Options)
- Solution 3 (needs more confirmation): Just reboot your phone once or serveral times after rom installation
- Solution 4 (provided by Pont91-unconfirmed):
+put all media files on internal SD;
+deleted all files created by any app on the external SD;
+set internal storage as main one for all the apps data (downloads, photo, rec, backups, etc.).
- Solution 5 (worked with many users): Set Never for Screen Timeout in Settings/Display, remember to press Power button to turn off the screen instead
3. Randomly reboot issue: (the phone suddenly reboots for unknown reason):
- Solution 1: (need more confirmations): Remove the SD card.
- Solution 2 ("Somebody's" CM10) : (need more confirmations): Turn off Wifi :cyclops: There are two guys who provided that:
+ Either turning off Wifi
+ Or set Wifi to NEVER SLEEP (Always on) by: Settings/Wireless & Networks/Wifi Settings/Advanced/Wifi sleep policy
can help stopping reboots. Not only for this problem, but even the issues of heat and deep sleep can also be improved. From their reports, it seems that there is some problem related to the Wifi driver with "those libs". So, try this solution at your own case and help our devs by confirming this way again. Tks.
4. The heat issue (the phone seems to keep hot all the time): The issue seems to walk along with the deep sleep problem, so the issue may be cleared when the fix for deep sleep is applied.
5. The battery life: So bad
Both ICSROM (known as the leaked ICS) and CM10 with "those libs" have an identical problem of battery life. As shown on my phone, the battery drains from 100% downto 50% just after a couple of hours in usual use, even if your phone is in idle state.
No fix yet for this issue But you can apply some of following improvements:
- Lock (freeze) unnecessary AT&T apps and services (ICSROM only)
- Turn off Auto Syn (Manually mode instead)
- Turn off or lock all tracking/reporting sevices you doubt
- Use static wallpaper instead of live one
6. Ram low or several other suggestions only for ICSROM: clike here
7. The I/O performance is a characteristic weakness of both roms which are using "those" libs. You can see this on the results report of Quadrant. Essentially, you can see that the data processing speed is significantly slower than the CM7.2 by using, for e.g, Call Log Backup & Restore, etc...
No yet improvement for this disadvantage of both roms
8. Blackscreen issue after a lock/unlock: CM10 23-Oct build FIXED. But some users reported that the bug is now still there on their Atrix. So, the best way is that you flash and experience yourself to check whether the fix works on your device
9. Black incoming call screen and blackscreen issue after a call: CM10 23-Oct build FIXED. But some users reported that the bug is now still there on their Atrix. So, the best way is that you flash and experience yourself to check whether the fix works on your device
...Other issues (please share and provide your own solution...)
Thanks for continuous reports from you guys!

Thanks For your report!
My phone is an US AT&T. Installed ICSROM yesterday (WOW!!!) and confirm what you posted.
Biggest bug is the battery. It seems to consume 1% every minute! In an hour I was down to 40% after full charge and using Play Store on wifi. Webtop/Mirror mode works awesome! Watched some HD videos and listened to some music... all good. After using the HDMI connection, I confirm that you will not get black screen until you reboot the phone. Turning off any screen unlocker does not fix the deep sleep bug. 1 reboot. Overall, it is very good.
Keep up the great work and thank you for your efforts! :highfive:

I think I saw some workaround suggested by somebody to turn on the torch before using the camera. This way, you've a constant camera flash
Not sure whether it works as advertised, I've not used this ROM yet.

It works
Anyway, it seems i've stopped deep sleep reboot, with external SD inserted, in this way:
-put all media files on internal SD;
-deleted all files created by any app on the external SD;
-set internal storage as main one for all the apps data (downloads, photo, rec, backups, etc.).
Hope this can help you in some way

Really this fixes the deep sleep bug? Have you made tests for a long time of usual use? Pls confirm.
Can anyone else confirm this fix again?
First of all, thanks for the report.
Regarding the FP reader - what's really working and what isn't? Could someone enlighten me there?
As I'm back to cm7 right now, I would like that if you find any bug/fix, PM me. I will put it on the OP in the dev section.
Oh, btw, the flash workaround was my idea
I heard removing the SD card fixes the reboots.
Sounds like this might be similar to what pont 91 talking about.
Is there any fix for the upside down front camera in "somebody's" cm10?

Not sure if this is a bug with the roms (Somebody's 10/19), but I'm not longer able to track total data usage on my phone. Some apps will show the amount used by individual apps, but none will actually total it up (They all say 0 total data usage).
Woah where you getting October 22 from???
Fixed

D801 Wifi Shutting down after Bluetooth enabled bug question

Is there any reason this bug has not been fixed yet? I"m generally curious, not trying to come off as a prick. Is it something major or the devs just ignoring the problem, or maybe not really aware?

Also i noticed most of the time vibrator stops working while typing fast on keyboard or using one button navigation
Many users with same issue have reported on Lenovo's official forum thread, but they haven't provided any working solution
i can't post the link due to forum rules,new to xda?
Any Solutions to this issue?

I had the same problem, except my device was a warranty swap because the first device had a defective speaker. I called customer service and had them swap out the vibration defective device. My opinion is someone at the manufacturing factory had a bad day and devices weren't put together properly. I would call customer service

How much did they charge ?? I dont have the warranty anymore!
i seem to have found a fix, just use ex kernel manager and reduce the vibration intensity. it worked for me, might work for others as well
