Xperia Z3 :: Constant Reboot - NFC Turning Off / On And No Signal / Data
Oct 17, 2014
A few hours ago I noticed that I had no signal on my phone (which is strange because I usually have good signal at work), and on closer inspection I could see the NFC symbol appearing/disappearing constantly in quick succession. After a few mins my phone then rebooted itself, and since then its been booting up, the NFC symbol does its flashing on/off for a few mins, then the phone resets again and the cycle continues!

my x10i keeps dropping its wifi connection. it is in an "excellent" signal strength area. i can now see that is related to my poor mobile network coverage at home. when the mobile network signal drops, then the wifi turns off and the turns on again, scans and reconnects. when the mobile network connects again (after a minute or two) the wifi turns off, then on again, scans and reconnects. this cycling is happening every minute or two. which leads to lots of frustrating network errors. exact issue described below with Internet clip: [url]. things improve if i turn off 3g and set network to gsm only.

I purchased the n900 and really loved the phone, but had to send it back because of the constant reboot problem. I want to get the phone again, but only when the problem has been properly fixed by Nokia.Does anyone know if the latest firmware update (PR1.1) has fixed this problem? One other question. Is it possible to turn the phone completly silent and only have the vibrate function on? I turned the phone profile to silent and turned the volume down on everything, but it was still making noises when the screen was pressed.

My wife just a 9650 through VZW. This morning it starting doing the constant reboot thing. I know how to fix it (since her old Curve would crash all the time), but anybody have ideas on what would cause this? She doesn't have many 3rd party apps (Quickpull, Buzzme, Google Maps), so I can't imagine it would be related to low memory. Is daily scheduled quickpull perhaps overkill on this phone? I'd like to do to avoid it crashing again, since I'm the official "phone fixer/OS reinstaller guy".

The phone constantly resets when trying to connect to unknown networks that require a password. It took me ages to figure out what was causing it and it's a real pain. You could just be walking down the street and it'll try to connect to a WiFi network that will kick off this constant resetting. You have about a second to turn WiFi off, before the process starts again.
I mention EE as they have their own software variant that enables WiFi calling in the UK, not sure if that's relevant?

I can't seem to find this exact problem, so bear with me if I missed it. My problem is that when I did a bettery pull a couple of days ago, my 9700 went into constant reboot. I was able to correct this by connecting to DM and reloading the OS (.714). This was the same OS I was previously using. Now, when I do a BP, the progress bar goes all the way to the end and it just freezes. I have to pull the battery again, and reload the same 714 OS from DM. No help from TMO online help, so I thought I would ask here.

I upgraded my bold 9000 to os 5.0.0 last night and it is now in constant reboot cycle. I let it do all it needed to do whilst connected to pc blah blah blah and it now it just reboots all the time. Gets past the loading bar and then goes to the vodafone screen, then screen turns black, red light comes on, over and over and over again. However, when I plug it in to either my mains charger or the pc, it will boot up OK. Any help would be appreciated as it will soon be going out the window!! Or back to the shop.

Every so often, mobile data stops working (and no symbol for data on the phone)Signal strength is strong.Switching mobile data off and on again, re-selecting network, switching GPRS/3G does not fix it.The only way to fix it is to reboot the phone. I think it usually happens after I've been in an area with low/no signal for a while. (Obviously when I have the signal back, I expect the mobile data to also come back automatically).Neo 2.3.4 Operator Simyo (Spain)It also happens to my wife's phone (Neo 2.3.4 Simyo as well) Is this a known bug?

Wifi on Lollipop 5.0.2 takes to much time to connect. It used to connect fast in KK.
When connected to Wifi it shows connected whereas the the Mobile data sign does not disappear unless as quick. Only after the Mobile data signal is disabled after 10 secs the connection starts working.

I have a Z2 that got stuck in a reboot loop after attempting an update. I'd like to make sure I get a copy of my data before I hand it in to have it fixed.

Is there a way to disable APN without disabling data traffic? I have seen some different apps doing it, but how can I do it manually? I ask because I only use wifi and not 3G.

I got my Nexus 5 on the 2nd of this month. I'm on Android 4.4.4. Just today, I was out and about and I realized that, although I was going into settings and turning Wi-Fi off, it just kept turning it right back on! (I had been using the Wi-Fi at the mall, then later I went to a friend's house and connected to my friend's Wi-Fi, which did not work.) So, I turned on my data, only for it to turn off after I guess about 30 seconds. I turned it back on, went on WhatsApp, in the middle of replying to a text from my friend it goes off yet again! What the... So, I went into settings and turned data on, and Wi-Fi off. As I watched, the Wi-Fi switched itself back on, and, predictably, even though there were no wireless networks to connect to, my data turned off as well.
This is really inconvenient. What could be causing the problem? I don't think I've downloaded any apps recently, but they do sometimes update. It was working fine on Thursday, but I've had my data off since then. I also booted into Safe Mode, and the problem doesn't seem to persist.

I bought my BB Curve 9360 last Friday. Today, I installed an app, which turned out to be not-working, so I deleted it right away. Then, the device asked for a reboot - until now it is rebooting.What I see is the Blackberry logo, and the loading bar, accompanied by the red LED in the right upper corner flickering. There is no getting past that screen - once it loads completely, the screen goes dark, and it starts all over again.So inspired by similar problems posted here&in other tech support websites, I decided to download the Desktop Manager and try to update the OS. This is where I got hit by a second time - although it is connected via USB cable,the desktop manager won't recognize the phone as connected, the phone won't show up a selection screen as to what I want to do (storage/sync... etc.) Yet it asked for my device password, which I entered correctly, and could choose the Update option. But while downloading the update, it suddenly stops and tells me to either check my internet connection - which is UP - or try it again later.

I understand lots of people have had the same problem, but I just cannot find a solution which works for my Blackberry 8520!It has a white screen showing nothing, it boots once you put the battery in, and the only way to power it off is to take out the battery, I think it also keeps rebooting.I have replaced the screen - still white screen.I have re-installed the OS - still white screen

In central jersey. The 3G data fr few users has been a hit or miss especially in nj at least that's what I been reading on the forum. Anyway my point is if edge is working fine and fast (for edge speeds that is). Then it can't be the antenna. Att must be updating 3G somehow.

I frequently lose signal in my work place because of bad coverage. When this happens, my phone is unable to retrieve any signal until I reboot it.Â
I have tried activating and de-activating Airplane Mode to get the phone searching for a signal again, but this no longer works.Â

I've had my phone since April and has recently started to experience a lot of problems with the handset. I'm best mentioning that my technical know-how is very limited in terms of phones, but I've accepted the fact I'm going to have to run a factory reset on my phone. So the problems I'm experiencing:- All of a sudden, apps start crashing one after the other. So much so that I can't even turn the phone off properly and just have to hold the power button down until it goes off itself.- Sometimes it just freezes, and when it does, it rapidly drains the battery.- Other times it just randomly decides to turn itself off (this has happened during the night resulting in me sleeping in for work because my alarm has failed to go off!)- When apps have crashed and I've had to turn it on and off again, all information stored (ie. texts, photos, Twitter feed) after the 16th October is gone!I've even went on Kies Air to start transferring photos, videos, etc. to my laptop, but even that keeps crashing, meaning it constantly disconnects from the laptop. I cleared out a lot of old apps I don't use anymore, but they reappear when I turn it back on, resetting back to pre-16th October like I mentioned.

If anyone is still having problems with the signal strength, try turning off 3G and Location via Settings section. I constantly had only 1-2 bars, but once turning them off my signal has improved massively; now getting 5 bars 90% of the time. I reckon it is more 3G affecting the signal, but try with both off just to be sure. If it works, then turn on 3G only when needed.

My M8 isn't receiving signal, everything else works fine, I checked the sim card in another phone and it works.
I did notice that airplane mode is stuck tuning off.
I rooted the phone (very new to rooting) but didn't go so far as to flash a mod. I unrooted the phone back to stock. It was fine for a couple of weeks, then one day randomly lost signal.
I've tried factory resetting but no luck.

I turn the WiFi off in the notification panel, but it keeps turning on and connecting to a WiFi signal I don't want it to. Even if I tell it to forget that network, it pops up again and connects to it.

The WiFi and celluar signal icons will occasionally turn grey for a minute, and then go back to blue.I thought that this meant there was a loss of connectivity, however when the icons turn grey I can still connect to the Internet and the signal bars always indicate a strong signal when this happens. I suppose it's possible that connectivity was actually lost for a moment, and it may take the icons a few seconds to update back to the blue color again, hard to say.

Every so often, my Nexus 5 (stock, unrooted and un-rommed) will freeze (normally when playing either Castle Clash or Asphalt 8) and i'll have to force reboot. This is not a problem. It happens.
My issue is when it powers back on, Wi-Fi will be on, even though it wasnt on before the force reboot. This has only been happening since 4.4.3. While it's not a major issue, it is a minor annoyance. Ive checked my Wi-Fi settings and everything is normal. Is there anything i can do to sort this?

Bought the phone on the day the phone was released. Everything was perfect until today. Endless reboot. The signal indicator is crossed out (red crossed out circle). Makes me think the radio is somehow fried. Tried factory reset.. Same thing. Endless reboot.

The wifi antenna regularly turning itself on to check for signal is a cool feature, but it opens over running applications causing the background application to freeze (most notable with my flashlight app) or run without me and not accept any input (many games). Set this to only request to connect to a network if no other apps are running.

Is it possible to disable all the telephony functions of the Xperia Ray and still be able to listen to FM radio ? (to improve battery life)
"Plane mode" is unfortunately not an option as it doesn't allow listening to the radio... (whereas it allows you to connect yourself to a Wi-fi network or to receive GPS signals, for instance) Would be great if there was a widget "Enable/Disable GSM networks" or something like that, as there is for other functions... but I couldn't find such a thing.
