[Q][A700] WiFi not working - Acer Iconia A700 and A510

Hi
I have Iconia A700 with originally stock ROM.
Yesterday after battery drain tablet switch off as usual. But after full charged - WiFi cant switch ON!
It just stack with: Turning Wi-Fi on...
And is for more then 10 hours! I switch off tablet many times, I reset them with paper clip, nothing...
Is any thing I could do before I heat "factory reset"? (I hope factory rest will help).
Thanks for any suggestion.

[Q] My phone keeps turning off.

My phone will randomly turn off out of nowhere. Earlier today I had 17% battery and it just turned off instantly. I turned it back on and had 87% battery. About 10 minutes later it instintly turned off again and when I turned it on I had 25% battery. It's getting really annoying. I never had this problem before, nor have I ever dropped it.
Is there something wrong with the pins on the back of the case or something?
Thanks in advanced for the replys.

nvm................
i had this same issue, for me it helped to move all my apps back to my SD card and reformat my sd card. Since then it happend once again and that was after i dropped my phone and my sd card unmouted. but besides that occasion havent had it for about a three week now.
might be related to moving apps to sd card, not sure do if this actually started the problems for me.
I m on stock ROM and i live in europe
I've got the same problem since about a week, phone randomly turning off. Though never when i'm using it, alsways when the phone is in standby mode, including the strange battery level jumps. I thought it was an app so i did a hard reset, but the turning off remained. I switched from Sense to Launcherpro, still no change.
My phone runs on stock rom, 2.3.4, Sense 3.0, Kernel 2.6.35.13
This weekend i'll backup my SD-card and reformat it, if this helps i'll let you know.

Been there, done that; problem still exists... I have tried a new battery new software (factory reset and hard reset in the repair centre), boardsap, other simcard, other sd card... The problem still is there, I am trying to get a new phone. The problem is the phone ... My question is is this only a normal sensation problem or is this also a problem on the Sensation XE?
My phone is starting to show the same symtons again. Overnight it also has shut down. So i guess the sd format did not get rid of the problem. But on my phone it definitively made it less frequent. As before the format i had it 5 times a day and now i have it once a 2 days. Probably will get worse overtime as the last time i had it.

Let me know if u succeed, i contacted HTC today and they told me to factory reset my phone. Not looking forward to that, do. Might do it next week.
forgot to ask, did HTC give u those out of warranty our did u buy them yourself?
Let me ask you a question. Have any of you polished your covers to chrome? I have had the same issue of my phone turning off in my holster, but only when I have my polished case on it. When I put my spare one that has not been touched, the phone works flawlessly. Not sure if there is some weird static buildup that is shorting the phone. Also, to get it to turn back on, I have to pull the battery first.
I had the same problem on my Sensation, turning off randomly (not reboot). And the battery would display wrong reading once it is back on. Initially I thought this was due to bad rooting or a custom ROM issue, I restored back to stock and right there on the language selection screen on first start and without the SD card, it went off. That made me sure it was a problem something else. I thought then it would be due to bad charges in the battery, used different charger to charge, didn't work, then I replaced the battery, somehow the problem stopped and when I insert back my old battery the problem still didn't come back. I don't have an explanation to this behavior. It works fine now.
That sounds weird, I didn't polish my back to chrome... And I also do not need to pull my battery to turn it back on. A few times I had that it turned of and it would directly turn of again after it was restarted (home screen loaded). The only way to get out of that was to hook it up to the charger.

It's really odd. I can't even use the phone any more.
When I turn it on, as long as the screen stays on it will not turn off.
Once I lock it and put it in my pocket, about 40 seconds later it shuts off. This isn't just powering down, it just instantaneously shuts down. I also can't turn the device back on no matter how many times I press power, I have to physically pull the battery and put it back in to turn it on.
One more thing to add: My girlfriend smacked my phone out of my hand once accidentally and the case doesn't click in. It stays in place but if you hold the case and attempt to take it off it falls off. I'm thinking it could possibly be a problem regarding the pins, but from what I know the pins only control the screen.
Edit: One last thing, when it's connected to my computer and being charged it never shuts down.

I had this same problem two days ago. Left work and my phone just shut off while in my pocket. I was running sense-o-maniac Desense 3.5. It continued this behavior for the next day. Also my battery was showing random charge percentages. There were two issues"
1. I was had used the battery calibrator app from the market to erase my bat stats - problem - it kept erasing my battery stats.
2. I was using set CPU and after reading many dev forums about such issues, I realized that setting the idle below 384 mhz, it causes the phone to random reboot.
Once I conducted a complete wipe and flashed MIUI I was good. no issues.
My Suggestion: Try a complete wipe, then Android Rev HD wipe, then reflash, Wipe cache, Davlick Cache, Fix permissions, then reboot. Drain the battery, then recharge to 100% and wipe bat stats

2nd factory reset and reformatting the microSD did not solve my problem...
@anari101: I'm a big fan of custom roms, but currently my sensation's still running a stock rom. I'd rather not void the guarantee at the moment by flashing it as the phone isn't functioning properly. If i can't fix this problem without flashing a custom rom, i can return it to HTC and hope for a repair or a new device/battery...
Anybody got any other ideas?
i also dont want to root a phone that might have problems.
I did not do any factory reset yet, but the problem is comming back now i have once a day it just shuts down. The last time when i picked it up and pressed the power butten the screen was white for a split second. However if i look at my history of battery monitor widget it stopped recording an houre earlier. clueless to why this happens.
If your phone is rooted, I agree with anari - use current widget and battery calibration to re-calibrate your battery. Let phone charge all the way and then some like another 2 hours. Use battery calibration to get rid of batterystats.bin. Let battery completely drain (Hopefully it doesnt shut off in the process). Definitely seems like something is wrong with your ROM's battery settings.
If you dont have your phone rooted. Have you received any updates lately? If a factory reset didnt help - go to your local Tmobile and just have them ship you a new phone. Not worth dealing with the issue and they can get you a new phone within a couple days.
EDIT: If you have NOT factory reset your phone. You can try to copy all data off your SD card, reformat it. Insert it, let the phone recognize and set it up then add everything back on. If that doesn't work, factory reset (after using Astro to backup all apps). If THAT doesnt work, go get a new phone.
I am having this same problem. Mine always happens when I take my phone out of my pocket after it's been sitting for a while. It also seems that my battery is always around 30-40 percent. It will unlock then just turn off. I turn it back on and after about 30 seconds it turns back off. The only way I can get it to stay on is plugging it in to the charger for a couple of minutes after turning it on and it won't do it again for a while. I don't know what it is but I'm thinking battery or SD card.

[Q] [I9020A] Problems: My Nexus S is acting up!

Since this morning my Nexus s has been acting up. I was tethering to my Transformer Prime because I was at work and we have no WIFI here. The phone was plugged. after a few minutes I realized that I had lost internet connection on my prime. Wifi link was still working. I checked my phone, I had no signal whatsoever when normally I have full bars here.
I shutdown the phone in hope a reboot would make the problem disappear. Press power. Nothing. Press power again, nothing. Pull battery, try all the possible button combinations, still nothing. Charger plugged in, did not rebooted my phone either. Bought a new battery. Phone rebooted again.
Since then, battery status is weird. The phone does not show when it is being charge. Battery level is moving up and down without reason. The phone is going into Airplane mode randomly.
I did a factory reset, Dalvik reset, Cache reset. still the same problems appears. Reflashed Stock firmware, still the same issues.
I don't know what to do anymore. Please help me!
Charge battery fully and do a battery stats wipe, then unplug it and let the phone die before recharging, will probably fix the battery if it's not a hardware issue.
Do you still get no signal?
It's hardware related, i can't charge, or don't know if it does. Tried to wipe battery stats earlier but nothing happened

Hi everybody,
I was on twrp f2fs mode 2,7
Last time i used cromi-kk f2fs internal
I installed over cromi-kk a cromi-x 5.4 with hunds extreme tweaks data2sd
Tottaly forgot to reinstal normal twrp reformat internal memory.. So i had that screen encryption failed,
I restarted my tablet to fastboot, and it hang up, after like 5s turned off automaticly, and since then stopped working.
I plugged in to charge and went to sleep ( for about 6h). Battery indicator was green when i waked up. tried to turn on unplugged, no reaction, tried to keep it 5 - 10 - 30 - 60 - much more seconds, no reaction.
Then with volume button and power, no luck, tried reset still nothing. (no vibrations, no nothing, just dead)
I tried connect to a pc, pc doesnt find tablet
Any ideas, please help
So i was playing around some time with my tab again. Tried to do stuff, still no luck, possibly i bricekd or i fried the motherboard ? Before 6 hours i left to charge and still is red light (charging indicator).
May somebody help me ?
Should i try to discharge somehow ( i do not know how, maybe by pressing power button, and stuff)
Or should i try to charge like for day or two to wait, maybe it will turn back on in twrp or fastboot at least ?
Latest news so far, i charged the dock, then i connected with tab, and puted in charge with charger, so there was a while ( for about 16 hours) and the light on the tab is till red, no reactions still.. So what should i do, maybe somebody knows some tricks or anything at all. Charger works fine.
Have you tried a hard reset? Little hole near the SD card, insert a pin or small paperclip, there is a button inside that will force a reset when the external buttons don't work.

You said early that you fully charged the tab (green light); then you said it later went red. How did this happen when you couldn't turn the tab on? If either the battery or the charging circuit is dead, then the tab won't get any juice. But how did the battery discharge itself from full to nothing without anything drawing a current?
i have got no idea, what happend, but today, my tablet, after some i think "coma" state turned on. after some game with twrp, i am able to use cromi-x 5.4 again.
Before person asked, and i will reply yes i tried hard reset button, i tried every single holes and buttons, hdmi and so on.
It just came back to life. (plus charging is fine, because my dock charged up, but tablet didin't, and now i can see it, it charges up again)
I do not understand what happend. Point is , im able to use it again.
Thanks for help

[Q] TF700t dead??

OK.... unlocked and rooted my TF700t to try to improve performance. was running TWRP 2.6.3 and Cromi-X 5.04. Not too bad but battery always showed 100% and seemed to run out inside 2 hrs with dock attached.
Recently I decided to upgrade to TWRP 2.7 and Cromi-X 5.4 the _that kernel. Battery problem didn't change so switched over to Hunds and same issues.
Last night I didn't notice power had disconnected. I tried restarting but it would start and then shutdown a few seconds later. Dock light was showing green but tablet would not stay on. I then connected power straight to table. It would power up but as soon as I connected back to dock it would turn off. It would seem from that I have a dock and tablet not holding a charge? I powered back up and ran 5.4 back to stock ASUS to see if it made a difference.
Situation deteriorated to the point tablet was not coming on so I was able to hit the reset pin and power on. Now nothing is working at all. Hard reset, pin reset, power straight to the tablet.
Any suggestions or am I looking at the bin???
Thanks,
Nicho
Edit: After leaving just tablet component on power for a couple of hours the reset pin worked again....take off power it dies. Attach to dock again and it won't start up even with pin reset

Phone turns off on turning on Wi-Fi/Data

Since two days now, my Nexus 5 turns off on turning on data or Wi-Fi or even taking a photo. I can't turn it back on unless I connect the phone to the charger. There is no drop in battery charge either on turning it back on. To use data and Wi-Fi, I always have to use the phone in charging mode. I even tried clearing cache and factory reset from the recovery mode, still no luck. Please help.
How long does the battery last if not using data or wifi at all? Sounds like the phone may need a new battery.

Well, the battery would last an entire day. I got the battery replaced a while ago and it is all good now.
