Browser - max 4 pages open

My browser will only let me open 4 pages. Why is this, any ideas? To prevent excessive memory usage?

I remember reading somewhere that it has something to do with how thumbnails are displayed.
The only way around it is installing an alternative browser like Opera Mini, Dolphin, Steel, etc.
Though I don't see why would you need more that a couple of tabs open on a phone.

Well I do seem to need more than 4 tabs open, just habit I suppose...
I have used Steel and Dolphin before, but I'm really liking the built-in browser, apart from a couple of niggles - the second one being that when long-pressing a link (to bring up the "open in new window" menu), half the time it launches the text highlighting tool :-(
Any idea what I'm doing wrong?

Might want to calibrate the screen?

I'm also finding that after browsing for a while, the browser will refuse to open a new page at all, it seems to start loading the new page, then stops loading part-way through.

This problem is now starting to really bug me.
I'm browsing for half an hour or so, and then the browser will just freeze up, and refuse to completely load the current page, links won't work, bookmarks won't open. Clearing the cache doesn't fix the problem, and since there's no way to exit the browser then I'm having to reboot the phone.
Anyone else suffering this way?

Hi
I have the similar issue, but it appears only when I switch from Wifi to mobile connection. The only solution I've found is kill browser. Can you please check if it's the same at your side ? if yes it's propably bug in web browser app, because market and everything else is working fine.

No, it's happening to me whether I'm on wifi or 3G (and not switching between the two). I don't have a task manager installed to kill the browser, so I'm having to reboot. Very annoying.
Also another persistent problem is that sometimes the browser will just quit with no warning, when clicking links. It's happened about 6 or 7 times, during (estimated) 4 or 5hrs browsing. When you restart the browser any open windows you had are gone.
I'm not at all impressed with the lack of stability of this browser. I know I could use Steel or Dolphin (with no Flash) instead.
I'm getting a replacement tomorrow, due to the "pink screen" issue, so I'm hoping this handset I have now is just a lemon.
Sadly, I'm thinking maybe they will all be the same. These issues, along with the poor calibration/recognition of where my finger is on the touchscreen sometimes, and the lack of a physical keyboard, are starting to make me re-think my decision about getting this phone.
Even more sadly, my friend's iPhones are looking increasingly more and more attractive :-(

If you don't mind for not having Flash (like iPhone), then you can download "Opera Mini 5" from the Market.
It is much faster and probably will give you better browsing experience.
I am using it for my WM device for years and cannot live without it.
The speed is just so damn fast!

[Q] phone downloading 80+ megs every night

About a week ago my phone started downloading 'something', about 80 megs of something, every night. It must happen in the middle of the night, I've never been awake to witness it happen. When I look at my phone in the morning I have no system messages, nothing indicated in download manager, basically no hint that anything had happened. I would not have noticed had I not been checked my data usage with my provider.
3G Watchdog attributes it to "Downloads / Media Storage / DRM Protected Content Storage / Download Manager". I have no idea what is afoot here. I don't remember much changing in the last week except for the Market update that was pushed out. No ROM changes or anything radical like that.
Look for advice how to isolate this and make it stop.
HTC Desire Z running Gingervillain 1.5
Thanks in advance.

There's nothing like a podcatcher that runs at night? Or maybe updates? Hmm...

Not that I am aware of. And I hoped that 3G Watchdog would tell if that was the case (I only installed it last week, to try and sort out this problem.)
I have my market updates set to manual. I'm not subscribed to any media services as far as I know. And this is the same amount of data every night. Is there any possibility I'm received an OTA Android update or something that my phone doesn't know what to do with?
I tried *#*#4636#*#* but could not figure out how to get any bandwidth usage stats out of it, so for now this is all the detail I have.

If you don't have any podcast apps installed and set up to run, or anything obvious like that) you could always mount your media card on your computer and sort by date to see what's new.

Thanks, good idea. I just did a complete search via USB connection (I assume this only checks the SDCARD and not the phone's internal memory?) and I can't find anything new from the last few days. There were no new media files except for a few photos I had taken, and no large system files or anything I couldn't explain.
It definitely doesn't seem like I'm lost 80 megs of storage every day, I probably would have noticed that (maybe.)

Only thing I can think then is to check your sync settings and make sure all the apps you've installed since this has happened are from trusted sources (a few botnets have shown up in Android recently); that and go through your list of installed apps to see if there's anything there that you didn't install (note: there is a rogue app that is listed as 'System' but doesn't have the default Android system icon out there).
Does the app that caught this distinguish (damn, how do you spell that word?) between something actually being downloaded and just general network traffic? Your device may just be hammering the towers for a better signal or something like that.

Actually, there's a means to do this in Spare Parts
Dial *#*#4636#*#* (or launch Spare Parts if you have it installed)
Click Usage Statistics
Click Battery history
Click the Other usage dropdown
Click network usage
Since this is happening at night, you'll need to reboot before bed and then select "since boot" to see what happened overnight.

I just eyeballed all of my applications and I don't see anything I don't recognize. Nothing called System. A few system-ish things where I don't know what they do, but they all have Android icons.
I did have all untrusted applications selected because I installed the Amazon app store a while ago.
The Watchdog app seems to indicate the downloaded data is happening all at once, it's not cumulative data from the day, I can update it real time and see what's happening. Moreover, nothing has changed with my location or phone usage, and I normally would have 1-2 megs of data usage a day tops.
Tonight I will shut of 3G data when I go to bed and I'll see if it generates any kind of warning overnight. Good thing I have a big data plan...

twelvebit, I ran into the same problem you had as my phone was also downloading 80-90 megs data every night for about three days before I noticed it. I also narrowed it down to Download Manager. Another problem I had with it is that it uses a constant data connection at every phone bootup. I had to manually force stop Download Manager at every bootup so that it'll free up the data connection again. I pretty much went through my phone and SD card and there was no new files of any type. I don't use any podcast apps. I also didn't install any new apps before this started. After a couple of days of trouble shooting, I gave up and just did a complete wipe. The phantom data stopped after I reinstalled a new rom and hasn't pop back up since. I was running CM 6.1. Sorry I couldn't be of much help.

I just turn my data off at night because for some reason my phone would do the same. I even got rid of my weather widgets because I couldn't figure the problem out. For weird reason android does that mystery downloading.

So I left data off overnight, and as soon as I turned it back on this AM it immediately did performed the phantom 77 meg download. There was no indication on the phone anywhere that it was downloading anything, it's only because I looked a my usage stats that I saw it happened.
Guess my next step is to wipe...?

I flashed to the nightly cyanogenmod this AM, and in doing so I guess I lost my stats. I've never really used spare parts before. It doesn't look like "the" download has been attempted since I reflashed, but that's typical since it happens once per night.
Right now my biggest network using item is called "0", the others are dialer and android system. What is 0? When I try and select it, spare parts crashes.
Is there a way to get hard numbers out of spare parts, or just the graphs? (it's showing blue and pink bars for each.)

Not sure what '0' is.
Spare Parts just gives you the bar graph but I did another search and found 'Stats' and 'Onavo' in the Market, both should help you find the problemed app. Again, Spare Parts should show it if you reboot before bed and then check it in the morning and narrowing it down by "since boot".
EDIT: I take that back, hit the bar graph in Spare Parts and it gives you the actual data.

Guys, I'm having the exact same problem and I am puzzled why it's happening. I came across something from the droid forum:
In brief, to quote the poster:
I found a thread on the Cyanogenmod forums that supports the idea that while my oldish CM kernel was effectively blocking an OTA from installing, it wasn't preventing it from repeatedly downloading and attempting install. There is an app to fake the fingerprint so an OTA is not even downloaded since it appears to have already been applied. Just installed it so no confirmation of the fix yet, but I should know in a day or so. I'd pretty much concluded that the issue was an OTA since it was always coming via 3G even when I was at home with Wifi on. If it had been a misbehaving app, it would have originated on the phone and would have used Wifi. An OTA originates from the carrier so always comes via 3G. IMHO.
Any comment?

It's a little too early to declare victory, but last night was the first night on the new ROM and the phone did not do any inexplicable downloading.
If I learn anything else I will post it here for those others who are suffering the same issue.

Get traffic counter. It'll tell you what's using those megabytes. I used almost 1GB on my phone and it was the friend stream app on HTC Sense & Sensation.

Rooting issue

OK so I rooted my Note2 yesterday. Fairly straight forward and fairly quick folowing details on http://galaxynote2root.com.
Just came across it on a video on youtube and it seemed quick and easy.
Anyway It worked a treat and I have superuser rights, I installed Network spoof and wifikill and both programs run as stated.
I have just noticed that my battery seems to be on a constant drain since either (A) I done the Root (B) I installed either of the two programs.
My memory usage is also always tipping over the 1G mark.. I usually always close apps when I remember and clear the memory
I just cleared the memory and it closed 51 applications and reduced the memory to 650, And by the time I finished typing the memory usage is back up to 750 and nothing has happend! the screen had not even turned off.
Is there something happening?
Thanks

OTA Updates
Also noticed that the OTA updates doesn't work. Can updates still be applied via kies?

No pal. You won't be able to receive Kies or OTA updates. At first Kies wil download the new firmware if available but later just before flashing it will stop by saying you have modified your device or something like that. So in case of an update just download the ROM from sammobile.com or elsewhere, and flash it via Odin, pretty easy.
And I don't think rooting is hampering your battery backup, it might be those two apps, or other apps. Install BetterBatteryStats and monitor. You have NO idea how much juice could be drained by hidden ads in a free app.

In BBS the stats you should be looking at are Kernel Wakelocks and Partial Wakelocks, more so the latter. Set the time to Since Boot or Since Unplugged.
This tells you what is preventing the phone from going into deep sleep when screen is off.

The Dreaded "android.process.acore has stopped" Error: Is there a Master List of....

The Dreaded "android.process.acore has stopped" Error: Is there a Master List of....
So I got this error withing hours of first turning on my new Galaxy Note last night, and I just figured it was because I disabled an app I shouldn't have. So I reset to factory settings, and everything was fine. Fortunately, I'd saved most of my big media to the SD card.
Today, I got the error again. This time, after wandering the Internet for a while, I was (very haltingly) able to get rid of it by clearing the "Contacts Storage" cache.
Looking online, there are apparently three apps people suggest clearing the cache for to get rid of this error. So, the logical thing to do would be to disable all three apps to prevent the error from ever popping up in the future? The three apps are:
Contacts
Contacts Storage
Downloads
I don't believe I ever make use of any of them, except maybe the Downloads app, depending on how it works. When I download something from Chrome, for example, I always use the ES Downloader w/ ES File Explorer.
So--my question is this: are these three apps safe to disable? And a related question: is there a master list somewhere of the various pre-installed apps Samsung put onto the Note 2014 that are safe to disable? With no app windows active, my note idles with 47% RAM usage which seems excessive to me, and I'd also like to minimize the chance of future errors like the android.process.acore thing.
Of course, I'm also an idiot, so it's entirely possible that the best course of action for me is to just stop talking, stop messing with apps, and just leave everything as-is.

Yes, why not? And I will not say that you or someone else here is an idiot but I never understand this cleaning and killing. I mean like you see, your tablet becomes only instable. And there is really no lag of memory. The note has mostly 3GB which is more then most high-end phones have today and enough. And when the note use this memory then be happy because then the resources are perfectly used.
So, why removing stuff when you can't use the free space?
PS. I never got this exception and I use all 3 apps.

My understanding is that the error is caused not by the app per second, but the update process. Like the data gets corrupted somehow.
Anyway, as for why I want to do this, my understanding is that all of these pre-installed programs are constantly running in the background... which means they're consuming battery power. By disabling some , if I can, I hope to maximize battery charge.

I had that error on boot when installed gravitybox xposed module, just ignore it.

I was able to get rid of the error after several resets, but I'd still like to disable some of these background apps to improve battery and free up some ram.
I thought for sure I saw a master list thing here, somewhere, but the thread must have had some weird title or something because I haven't been able to find it again.

6.0 Makes N7 Feel Like a New Device!

Am I alone on this thought? I was really thinking about selling this tablet a month ago and decided to wait for the update, because I knew how terrible Lollipop was/is. I really am glad I waited, this tablet feels like a brand new device! No lag, approximately 650MB being used on average!, battery life is amazing, WiFi connection doesn't drop anymore, so far I can't find a flaw! If I did, there are so many pros to this update it couldn't take away the happiness I feel about what is better!
What do you think? Am I alone on this thought?

I think it's great too. Much more polished. The only problem is that I can't access my microsd using user apps that don't require root.

Really? I thought that was one of the major changes to 6.0? Very strange... I don't use an external SD though, but still, strange nonetheless. I wonder how the Moto X Pure will do hearing this, considering that's a big selling factor for it.

Micro SD is accessible via system app. Once you insert your portable storage, go to Settings/Storage & USB and there you will see your portable storage drive. Click on it and you will be able to access your files. No problem watching movies stored on my micro SD. :good:

Unfortunately wifi option doesn't work properly and you can quickly drain the battery if you don't turn off wifi when you haven't access. Keep wifi on during sleep option is broken.

The catch is you can't access your files if you're not using a system app or a user app with root access. Since most multimedia apps don't actively ask root permission, they won't have rights to access the microsd folder created under "/mnt/media_rw". You can't change the permissions to the microsd folder either. Perhaps if you set up your microsd as "internal storage" (see adoptable storage feature) instead of "portable storage" all multimedia apps can access it (since these apps have permission for it, of course), but Android M didn't implement that feature yet, at least as far as Flo is concerned.
Luckly Chainfire's Stickmount app uses its root rights to mount the microsd inside the internal storage (under sdcard), where all apps have access.
I was quite shocked to find out that a feature like adoptable storage, which has been announced by the media as Google finally playing along fairly with external storage, seems to be actually quite the opposite.

in this light YES it feels like a "new" device ... coming directly from a backyard in china with cloned firmware not belonging to this hw ,-)
would be interesting what TO understands as "battery life is amazing" when standby lasts max 2days.
Having to en-/disable WiFi everytime I want to use my tab is anything but amazing.
To add another one to the list: access from PC via USB doesn't work either.
One has to enable developer settings to switch USB to MTM allthough it is allready selected, charge only seems to be default with no possibility to change for standard users.
This seems to be the most untested and buginfested "upgrade" I encountered in my Android history.
I doubt even M$ could do worse ...

I have that usb problem too thats some bull****.
Battery life is pretty damn good I got over seven hours screen on time over 3 days with not light usage (no games). I don't have any wifi problems but even a bad signal shouldn't drain it since Doze should shut it down so I'm not sure what would be draining your battery. I lose 1-2% overnight.
My biggest problem with 6.0 is Doze. Turns off everything for good standby time, works great for that but now I don't get lots of notifications like email or calendar when it's dozing and excluding them from battery "optimization" does not work. They gotta fix that ****.

looks like I'm not alone with WiFi battery drain.
Maybe it is related to the LTE version?
Today I lost 20% overnight ... on a freshly flashed system w/o any installed apps, not even google account.
Just WiFi credentials and set keep WiFi on to never ...
Good time to test the CM12.1 ....
Edit: somehow 6.0 fails to recognize my 16GB Lexar 3.0 USB-drive. It says it's defective and offers to format but fails with a runtime error. The same USB-drive works w/o problem on my lenovo.

Has anyone have issues downloading files using Chrome? I use CF Lumen, and Chrome prompted me to disable that, which I did. Tapping links for downloads has no effect; I tried multiple sites to be sure. Weird!
[EDIT] Delete please - I posted my question in the Lumen thread.

hmmm, mysterious.
yesterday I left it as is at my office and it lost only 5% in 16 hours ... allthough WiFi was allways on according to batt graph

Is this WiFi behavior normal for marshmallow? I don't think so... Any solution for this?
Unlocked bootloader and rooted

Hi,
at least yours doesn't lie to you. Mine pretends to have not been using wifi ... but if I shut it off, I can see the difference.
It is interesting that the periods where wifi is shown as off were situations where no wifi was available or couldn't connect.
Due to the graph and stats, wifi was on but didn't consume (allmost) any energy. But if I totally disable Wifi I can see the difference (battery life prediction: 15 days)!
If I sum up all consumption infos I get 258mAh used in about 9.5h. 258mAh are approx 5.9% of the battery (not 19%) and recalculated the predicted life should be approx. 16 times 9.5h ... so something is very flawed in this region.

Mine is exceptional, like 1-2% overnight battery usage. My only observation is when I set the tablet down and use it the touchscreen rarely registers a touch. When it is held in my hands and I use my thumbs it works fine.... It has a rubber tpu style case stretched over it, doesn't make a difference. It also has a tempered glass screen protector. Is there a way to turn up touch sensitivity? I know some Samsung builds actually had that option.
