Tab 2 7" screen flicker - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hey all
My tab 2 7" came by mail today. I booted it up and set it up. Used it for a while. And my screen began flickering very lightly. I hope i domt have to send it back.
The tablet is NOT rooted and on Jb 4.1.1
What to do now. Because it is very annoying.
Kind regards.

I recently noticed something else aswell. The tablet stays warm even when the screen is not in use.
I hope this is just software related.
The flickering seems to be gone btw.

This seems to be a problem with all the galaxy tab 2 7" mine also gets hot so I am underclocking and set my cpu to ondemand instead of interactive and that seemed to solve the issue.

But what about the screen flickering? Temprature related aswell?

up!

It's hardware related. Like ketut once said every tab is like a snowflake. They are different. I don't have this problem.

I have overclocked my cpu to 1.2 ghz and using hotplug governor... i have never experienced this issue even after long hours of gaming and watching movies... it does get pretty hot but no screen flicker...
What i think is that this issue is caused by auto brightness... try disabling it and check for a few hours... hope it helps

[Q] XDA app issue with long posts?

Does anyone else have issues with the XDA app when using the transformer?
Everytime I open a thread to read that has a really long post (usually the first one) the words all get smeared and garbled looking while scrolling. Short posts are fine though.
Sent from my Transformer TF101 using XDA Premium App
I have four Android tablets, which includes my ASUS Transformer. The others run Froyo. Not one of them can successfully use the XDA app - it crashes quite repeatedly. I've only tried the free one. It's possible the pay-for version might work better. I'm not willing to try.
Bye.

I see the same thing and I find it quite annoying.
I had this happen, but then i bought the paid version of the xda app and the problem stopped. Might just be lucky though

What display setting are you using within. The information get the issue with the "basic", white on black, and but the "premium", black on white with orange headers, seems to be fine.
Had the same problem. Display style premium and basic solved the issue.
The XDA free version does FC often.
Sent from my HTC Glacier using XDA Premium App
Ihave the paid app, no FC issues. But does anyone notice it uses data unnecessarily while closed? Is there an update for this? I usually just kill the app or turn off bg data. But I don't want it to happen anymore

Have you dropped the scaling down. And shut off the higher oc values? Typically that kind of thing is result of pushing the phone too high.

I agree with eollie, only time I've seen what you described is when I tried overclocking to 2ghz!

i used tegrak OC back when it didn't have the run for a minute and see whether stable option. And I had set on boot, OC to 1.65 just to see what happened. It turned on and then blurry freeze. Had to clear cache, and dalvik. Surprisingly, it worked.

I'm using CM10, and so far it's been great. I've had no problems. One feature I like the most is that you can respond to texts when you're not even on the MMS app.
Almost 3 full days. Not a single sleep of death. Battery life is on par with cm9. My only issue is a slight lag when unlocking the screen (about a quarter of a second)
It's a daily driver.

I find battery usage the biggest problem, can't even manage to make a half day with 3G data connection ON.
Web usage may be limited to max of 2hours. CM9 was better for battery for me could get a day with moderate usage.
Any body facing similar problem to me ? :banghead:

CM9 did not have Google Now, turn that off and you will see a huge difference.

Weird screen bug after unlocking?

So I've noticed this strange bug ever since I've had the phone. Sometimes after turning the screen on, my screen won't register touch input properly - ill try to do my pattern unlock and it'll just jitter around and not work. After turning the screen off and on again its fixed. Anyone else have the same problem? It's happened on stock and every other rom I've used.

Never had the home screen bug happen even once on my device... Its a bit irritating but not that bad. It never happens after the screen has been on, only right when you turn it on
Ah oke. We better pray for the jelly bean update then! Haha

In all seriousness, I'm not sure what time we're supposed to looking at to help. I see some wake locks happening for a few seconds.
I guess I didn't explain myself well... It's a picture of my phone off charging for a few hours.... But if you look at the line above it says statistics 0s (even though the statistics themselves have some seconds) and the detailed statistics are totally off - Google calendar had 24 wake locks for 2 sec while Tasker is over 1000 but under 1 second... All my setting are constantly skewed and totally off...
Sent from my Nexus 5 using xda app-developers app
Is it a one time event or did this ashtrays happen. I use betterbatterystats and I have seen something similar, but it's always a time event and goes away next time i boot or plug the charger in.
It's been like this for almost a week. I've rebooted multiple times and deleted cache.

Sorry about the spell correction, lol. Damn ashtrays. I guess the only thing I would suggest would be to uninstall and then reinstall the app. I would have suggested clearing the cache but you're already done that.
Here's a screenshot of betterbatterystats with a few minutes of usage... It's totally empty and it definitely shouldn't be...

Hmm, both are for 4.4 KitKat? 4.4 made it more difficult to get the statistics and bbs wasn't working for awhile. The new version does work. Maybe Rom related?
It's neither... I've had this ROM for 2 weeks now without any real changes and it just stopped randomly...
Sent from my Nexus 5 using xda app-developers app
There must be something wrong with the phone or corrupt on the ROM... better battery stats is only showing one wake lock (nlpwakelock)... Grrr

Thanks for all the help... In the end it's a ROM problem that a module in xposed can fix (except I'm on ART so I'm screwed).
Thanks for the help guys!
