I just purchased an A100 and was wondering if anyone else has the same problems I am having. Also any ideas would be appreciated.
I can't wake the tablet when it goes to standby> I press the power button and nothing happens. If I hold the power button long enough it will reboot. The other issue is with the wifi. At home it works ok, but at work it is another matter. It sees and can connect to the router just fine. When I try to go to the internet it tells me that there is no internet connection. I noticed that there was a little arrow in the wifi icon when this happens. I tried a reset to factory defaults, but no go. The sleep problem is unchanged, and now it will not connect to the work router at all.

I had the sleep problem wen I first got it but now its gone. But never had wifi issues. Just exchange for a new one.
I have the same standby problem. On top of that I noticed that there are some glitches.
When the unit is fully off and I try to turn it on by pressing the power button down for a couple seconds the blue light turns on but no vibration and nothing shows on the screen. I have hold the power button down til the blue light turns off then press it again and hold it down until it vibrates and thats when it turns on. I also tried grabbing the stock rom (made sure it was decrypted and put on both the root of the internal and external sd) and tried to recover it but all I get is a android exclamation mark no matter what I do.
Sometimes you just need to give it sometime to wake up... Because if you press the power button multiple times, it would not be responsive!

How long? Does your screen stay black while you are waiting?
yes. If it is unresponsive when pushing the power button (but you know the device is on), just wait for 30 seconds and try pushing the power button again.
On mine after i hit the power button the screen wont turn on for good 3 seconds. If I press the power again before that 3 seconds I essentially turn it back off so the screen never turns on. Till I press it again and wait 3 seconds for it to visually turn on.
Well, I took it back for an exchage and Microcenter was out of stock. I got a refund and headed over to Best Buy. Not much luck there, they are sold out in all stores, and online.
Have you tried fry's.com or gamestop.com?

I tried the Kindle Fire, and I did not care for it. The screen did not always respond to touches and I do not like the carousel. I also did like the lack of buttons on it, and it was heavy compared to other 7" tablets. I took it back and started looking for another tablet. I found the A100 in Walmart today and bought it. This one works a lot better than the first one, it wakes up from standby just fine. These Acer tabs(A100 and A500) are selling out everywhere it seems. I think they are priced right and are a very good value.

I agree... i have from few months and i'm very satisfied... but suro now you can find some better on the market...
In italy you can buy Huawei Mediapad and is a very good device, indeed... it cost something like 379 USD but have HD resolution, IPS screen and 3G...
Battery Indicator gets stuck...
Does anyone else have a problem with the Battery Indicator freezing while charging. It happens every time I plug in. Earlier today I plugged in at 11% an hour later the battery indicator (both on the lock screen and the settings popup) said 11%. As soon as I unplugged it changed to 76%. When I plugged in an let it charge again it stuck at 76%.
Anyone else have this issue? Any idea how to fix it?
The only things I changed system wise is: I froze Acer Content Folders, Acer Registration, AUPEO!, clear.fi, Facebook Web, and MusicA. And thats it!
I am having the same issue with my a100 not waking up. I sent it to Acer and they reloaded android, but the issue still exists...even after a factory reset with no apps installed other than stock.
The battery life was utter crap when I got this...but after 4 charge cycles...its much better.

Im not having the wake up issue but I am having a wifi issue. Wifi kinda works some of the time. The problem is it just cant stay connected for very long. It really sucks especially when im downloading a big file. Ivw tried wifi lock but it still loses signal. I usually just use the acer when im in my bedroom and our router is about 15 feet away. its very frustrating but dont know what else to do. also i cant believe how bad the battery life is! its not to big of a problem since i dont plan on taking it out of the house but man, why would acer make the battery smaller than most new cellphones?

Never had that problem but i had a hard brick. i like the tablet but if you just bought it get an extended warranty. there is an issue with the main board
I just got this tablet (to replace the garbage SGH-I467) a few days ago (Thu., May 15th). For the first couple of days it worked like a dream. However, the last 4 nights/3 days, I have been encountering some strange issues. What I will do here is describe the issues I've been having, what I have done in attempts to fix them, list some of the things I think may have caused it, and include any additional info/questions.
Before all that though, I would like to mention that I am not a developer, but I am a bit 'tech savvy' and am more familiar with/knowledgeable of technology than the average user. Also, I have spoken with Samsung tech support and even had the support guy access my Tab Pro 12.2 remotely (I will explain what I learned from that below). So, without further ado (I apologize in advance for the long winded nature of this post, but I want detailed):
The Issues:
1) Screen "flickering"—By flickering I mean that it is shutting off and turning on rather rapidly and sporadically, though inconsistently.
I first encountered the problem 3 days ago (the 18th).
Four nights ago (the 17th), before going to bed, I plugged the device into the same outlet I have used for all my mobile devices, when I woke up (on the 18th) the screen was doing exactly what I described. I hit the home button a few times and it stopped.
That night (the 18th) I plugged it back in to the usual spot before going to bed. The next morning (yesterday, the 19th), the screen was "flickering" again. I tried to press the home key a few times, as well as both the soft keys, nothing. In between "flickers" you can see the lock screen, where I have to enter a pin, but even while visible I can't type anything. So this time, to try to solve the problem, I held the power button + volume up to get to recovery and wiped the cache partition, rebooted the device, and viola, it worked again. Thinking that I may have to factory reset the device if the problem persists, I used Kies to backup all my data. I used the tablet the rest of the day, even plugged it in (in a different outlet than the one next to my bed) for a while and had no issues.
Last night (the 19th) I did pretty much the same thing, but this time, thinking that it might be an issue with the device getting too much power (the Quick Start Guide says: "Note: Connecting the travel adapter improperly may cause serious damage to the device."), I used a travel adapter from one of my other, USB 2.0 devices (the only difference between the adapters is the output: 2.0 = 5.0V—2.0A vs. 3.0 = 5.3V—2.0A, and output was specifically what I was concerned with). This morning (the 20th) the problem has returned, but now includes my second issue: the hard home button and both soft keys, back and recent apps, no longer function. So I immediately tried to wipe the cache partition and reboot, but this time it didn't work. Thankfully I had anticipated this yesterday and had that Kies backup, so I wiped the entire device back to factory settings. But alas, it was unsuccessful and the problem persists, including the loss of button functionality, with the exception of the power and volume buttons.
It is important to note that when I first got the Tab Pro 12.2 and set up the lock screen, I used the option that delays the actual locking of the device 10 minutes after screen timeout, but set it so that if I lock the screen with the power button it ISN'T delayed and immediately locks. That being said, a couple of times when the "flickering" stopped long enough to momentarily use the device, I was able to enter my pin and unlock. But when the screen starts flickering again, it locks the device, so the power button must be affected as well. Though since the first factory reset of the device, I haven't set up a pin. I have done several factory resets and none of them have worked. The best result has simply been limited (no back, recent apps or home key) and momentary functionality. I tried using Kies to do emergency firmware recovery, but every time I click the option it disconnects the device.
When Samsung tech support remotely accessed by device (I used one of the momentary functionality windows to download the required application) the agent was able to utilized soft and home key functionality, even though I couldn't. This tells me that it was hardware related, not related to UI/software.
So there are a couple of things I think may have caused/contributed to the problem:
The first, which I vaguely touched on above, is the power issue. Perhaps I have shorted the device out somehow. The outlet I use to charge things while I'm sleeping is on the wall behind my bed, so I have to use a common extension cord, one that has 3 outlets at the end. I have a light plugged into that and in the past have charged both my SGH-I467 (AT&T Note 8.0) and my SGH-I747 (AT&T S4 Active) with that cord and outlet. That is the only place I have charged the SM-T900 overnight, but none of the other power sources I have used have caused these issues.
The second possibility is a virus some sort. I have never used the Samsung app store on any of my other devices, but in order to update the Hancom Office suite I had to. Since I had an enjoyable time using it to that end, I decided to see what else I could find on Samsung's store. I downloaded a couple of things (the "Official Captain America game" and a couple wallpaper/theme apps) and was looking around the store to see if there was anything else I wanted to download. I found several apps that had reviews claiming they were trojans, so I immediately checked the reviews for the apps I had downloaded, but none of them had similar reviews. However, that does not mean they didn't have viruses.
So, what do the resident Android gurus of XDA think about these issues?
I tried searching all over the forums and elsewhere online for people having the same issues, but couldn't find anything. Have any of you ever encountered something similar to this?
Until recently, I hadn't ever heard of anyone getting a virus on an Android device. Are they common? What is the nature of Android viruses?
If these issues do have something to do with overcharging/shorting the device, how can I mitigate that problem? Tonight when I charge the tablet, instead of using the USB 3.0 charging cable, I am going to try just using the 2.0 cable. As I understand it, that can be done by simply plugging it into the right side of the port. Hopefully that will stop exacerbating the problem.
Again, I apologize for such a long winded post. I would like to thank you all in advance. If ever I have problems with an Android, you guys are the ones to ask!
*UPDATE* Before I started typing this I was attempting to run the Kies 'Firmware Upgrade and Initialization', as opposed to 'Emergency Firmware Recovery', to see if that too would disconnect the device. Unfortunately it said that my device needed to be charged first. So I shut it down and plugged it into a surge protected strip and began typing this post. Occasionally I would go over an check the charge. While it was shut down and charging I was able to use the home key to bring up the green battery. Once the charge looked like it was about 75% complete I turned it back on and lo and behold, the "flickering" issue looks resolved and so does the button issue. I can go back, enter the recent apps and task manager, and use the home key functions. For how long this will last, however, is unknown. I guess we'll see in the morning. I'll post what happens tomorrow.
What kind of case are you using? Some users have seen issues with some cases that use magnets for auto-sleep-wake. When the front of the cover is flipped back behind the tablet, the magnets seem to activate the auto-sleep feature

same issues here
Sounds exactly as the same issue I have had the last week. I have done several factory resets triad to avoid installing as many applications as I had prior the factory reset (to see If it was an app causing the issue). No solution yet but I will try your way with kies described above. I have a tab pro 8.4.

I am no guru, but it sounds like a loose connection. Maybe it is affected by temperature. Try it on a (not too) hot water bottle or on freezer packs.

It's not overheating. It can get warm, but it's never gotten hot. And I've had other devices that have seriously overheated and still functioned, albeit slowly.
**UPDATE**
After I got it working the night I originally posted I let it fully charge (it's important to note that I got it up to about 75% while it was off; green battery the only thing on the screen, and I had home button functionality), then disconnected it and disabled all the radios, put it in power saving and left it over night without power. Doing that I was able to use it all day yesterday. But while I was full-charging it, after it reached 100%, I noticed that it started acting up almost immediately. The sound was on and kept making the lock screen sound (that's how I noticed it from across the room). So it is tied to the power/lock key. But disconnecting it before it could get out of control mitigated the problem. Last night I was going to try to charge it over night with USB 2.0, but I fell asleep before changing the cable out, so it charged on 3.0 all night and is back in poor repair. I'm currently trying to full charge it while off to see if that gives me functionality again.
Either way, each time I fix it the solution becomes more difficult/timely than the previous one. It's clearly not getting better, so I'm going to have to send it in to repairs.

Sorta sounds like a screen grounding problem. I had a nexus seven with this issue and the charger seemed to really make it act up. Needless to say I gave that to my wife and bought this. If the digitizer is not grounded properly it will act up.
Turning on developer settings and set it to show touches on screen. See if when charging the screen registers more touches than you are doing.

Damn! That's an outstanding idea! The only downside is that last night I sent the tablet to Samsung's repair department, so I can't test that out. But once I get it back, if the problem persists I will definitely be doing that first. Thanks for the advice dottat.

Hey dude, check out dottat's reply. He's got a really good idea that may shed some light on the source of the problem. Unfortunately, I can't try it out. If you do it, let me know how it goes. Maybe you can take some screenshots? Either way, hopefully you can get something out of it.
I was looking and looking for a thread with a similar issue before posting but I had no luck.
My issue is that when I turn off my Note 3 I have a really hard time getting it to boot back up. This happens every time every single time I shut it off. I hold the power button for about a minute with the battery removed to supposedly drain any power as I've read around but that doesn't help. I'm pretty tech savvy and internally the phone looks perfectly fine. The weird thing is that I don't actually have any issues once the phone is up and running to make me think it's a hardware issue. It charges fine, I get data, S pen is fine, no other issues what so ever. I haven't been able to pin point what I'm doing to bring it back but eventually it does end up booting like normal. I try to pull the battery multiple times with no success. I eventually get frustrated and just leave it alone with the battery removed. When I return it boots up just fine.
Anybody else having this issue or heard of it?
Forgot to mention that the phone is stock. I don't have it rooted or a custom rom installed.
Thats weird. Have you tried reseating the SD card. Sometimes it might bethe memory card.
Why turn it off?
Just let it sleep. I can't remember when I ever turned my phone off.

I noticed you also have a thread which states the same thing and I'm not sure if you figured it out yet, but just out of curiosity did you happen to ground yourself while you were working on your Note 3? This goes for any device in general but it's pretty amazing how much damage the static electricity from just your clothes can cause if you're not grounded while working with an exposed main board. If you weren't grounded while working on it though it also doesn't mean that something automatically happened, I'm just saying it's always a possibility at least. One thing I would try if you're having problems powering it up even just in general, is to make sure it's plugged in and charging first and then hold the volume up and power buttons down together at the same time (and keep them held down) until you feel a vibration and then let go. It will take at least 10 - 15 full seconds (and sometimes even longer) to happen, but that should usually get it to power it up whenever it's being stubborn. Another thing I'd definitely check, especially if it was working fine before disassembling the phone, is the alignment of the power button itself (the button you press with your finger) and the actual power button which is located behind it on a data ribbon that connects to the main board. It's actually kind of a flimsy setup so whenever you reinstall the back frame plate you have to make sure the power button data ribbon doesn't shift, or it can cause all kinds of weird problems when trying to power on or off the phone. Anyway good luck and hopefully this helps [emoji106] [emoji106]

I just mentioned this in my response to someone else in this thread, but it actually sounds like yours has the same kind of alignment issue with power button that I was talking about. I'm not sure if you've ever disassembled yours for any reason or not, but even if you haven't it's still totally possible that it could've happened from the factory and especially if you got a refurbished phone for whatever reason. It's a pretty poor design choice in my opinion because it's such a "fragile" setup, and even the slightest misalignment of the power button itself and the button on the data ribbon can cause the exact same problems your having. Anyway if if you haven't messed with it and it's still under warranty I'd say just get a new one, but if you have taken it apart I'd say first thing to check would be the alignment of those buttons (once you take the back off). I've even had to make a tiny little "shim" and wedge it behind the power button on the data ribbon in order to get it to line up right with the button itself a couple of times, so I'd say it's a fairly common problem with these phones. Anyway good luck and hope it helps! [emoji106] [emoji106]

I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.
i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...
You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again
i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!
hmm. i'll have to give it a try. you think this may be something to do with condensation?
Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.
Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!
My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!
I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.
Hello,
I had been having great time with my Zenfone 2 ZE550ML but then suddenly a severe problem started. It started shutting down and switching on itself. Once the problem starts, it goes on for long. When the phone switches off itself while I am using it or its sitting idle in my pocket, and I hold power button to switch it back one, it shuts down again at asus logo. Only way I can make it work is my connecting the charger, and that too only for reaching the home screen where I also get prompted for the menu which you get when you are holding power button (the Power Off, Airplane Mode, etc). I removed the back plate to check the power button and its still tacky and intact, no signs of it being pressed. I don't know what is causing this problem. The power button menu (The power off, airplane mode menu which you get on holding the power button) keeps appearing at random times. Sometimes, it won't relax and go completely mad.
I have tried :
1) Wiping cache partition
2) Doing a factory reset.
3) Using phone in safe mode (problem still exists).
Will try downgrading to 2.18 firmware tomorrow and will let you know. So, for now, let me know if any of you have any solution for this problem. That would be appreciated. Need more info? Ask me
Recently : The phone had been fine for a few days and the shut down problem has started again.
My firmware version : 2.19.40.23 (it's the latest)
Thanks
I had random shutdowns and reboots as well (with the 551), albeit not as advanced as the issues you have, but they all went away after flashing SuperZen (I realize this isn't really an option for your phone).
But then again, because of how advanced it is (turning on by itself), it sounds like a hardware issue (like the power button - in spite of it looking okay).
This sounds like it may be a hardware related issue. If the problem still exists after downgrading, it may require sending in for warranty service. If you are within the USA or Canada and would like RMA assistance please feel free to contact me direct at [email protected]

I am getting occasional shutdowns when playing from Spotify over bluetooth when connected to my car (AUDI) and bluetooth receiver at the same time.
Flashing CM12.1 also didn't help...

What kind of shut downs did you have on your phone before flashing SuperZen? Was it on firmware version 2.19? Also, I think I forgot to mention, my phone sometimes switches down itself while at the ASUS logo (in search of incredible subline). I really don't know what to do until I downgrade the system version. Will let you know.

Hello, I am sorry, I am not in USA but India. I still appreciate your offer and help, thank you so much
I have a better idea. If possible, can any of you send me a picture of power button with the case removed. As well as the power button on internal side of case. I hope I made my words clear. I want the pictures so that I can see if my piece is defectrd. Can't send mine as I don't have a secondary phone/camera with me atm.
Thanks

Don't know what you mean regarding kind of shutdowns - sometimes I would come back to my phone, and (early on) it would be completely off - I turn it on, and there's plenty of battery life left. Later on, I would pull the phone out of my pocket, and the external storage mounted message would be waiting for me (theat, and once I actually felt the phone vibrate in my pocket only to mind that message later on).
Lack of logs (e.g last_kmsg) left me high and dry as to what the issue was. By the way, I was on 2.19.40.20 at the time (with BL unlocked earlier that week).

Don't know how good it will be to you - image quality is terrible - but please see attached.
Looks like mine has a little wear and tear on the button already.

Hello, thanks for reply and images. My buttons look exactly the same apart from the first image. The cloth like thing on my power button is not flat like yours. I fixed it and the problem still prevails.
Anyway, I am now in process of downgrading the firmware. Will update ASAP.
Okay, so the problem still exists after downgrading

Very possible that even though the power button looks okay, it could still be malfunctioning. And since there is no easy way to check the leads to it on the mainboard, seems as though you are down to two choices (and you cannot do both since the latter will void any warranty left):
Get it serviced (as in, send it away for such)
Do the tear-down yourself (and all the risks that come with it)
I will go to a service center next week.

Okay guys, its been a while now. My phone got fixed itself after the previous post by ASUS_USA. It got fixed itself so I decided not to take it to service center for now. But now, it again started the problem. Much worse this time. Phone got shut down with it reached 90% (happened twice). 90% exactly while charging. Today it got shut down again at 90% while charging, I tried to boot it up but it won't boot up at all . I shows asus logo at random times and goes off by itself. Taking it to service center now
I think I should've listened to my friend about not getting an ASUS phone in the first place

Guys at service center said that my phone's motherboard is defective so I sent it away for 5-6 days. But my question is, how is this even possible? The phone had been working fine for the first month. Are there any chances that motherboard will get defective once again after repair?

Hi, Ashish here.
I'm experiencing similar issues with my ZenFone 2 Laser. Can you tell why it's happening? Did u got your phone serviced?
Hello.
My phone is also having this problem. I was on Lineage, did factory reset, got back to stock but none of these worked.
Now my phone only works when pluged to the charger. If I disconect to the charger it only lasts about 5 minutes.
I will try to take my phone to Asus service this week, but please inform about yours as well.

How frequently is it happening?
Looks like that it is a hardware issue particularlly battery. The battery can't handle the load of the phone that is why it shutting down it only stop shutting down when charging. Need to replace the battery
