[Q] Xperia Z3 - Extreme contacts and messages lag - Xperia Z3 Q&A, Help & Troubleshooting

My co-worker has a brand new Z3 with issues. After literally one day usage phone developed extreme lag when accessing contacts or text messages. All the UI seems to be working fine, no hiccups here, but the content...
And I mean it, i have seen it with my own eyes. You click open dialer or recent log, and it takes minutes for the phone to display contacts. No freezing, simply empty list opens, and then after some time it finally shows the calls. Contacts backup (~250 entries) lasted for about an hour. After factory reset everything was fine for another day, now the same problem appeared. Do you think it's hardware issue some memory problem, or faulty software? We are planning to claim warranty, but i'm affraid they will just reset the phone and say it's good as new (for another day or two)..

Multipule issues :-(

Hello XDA.
Ok. Got my x10 in September prior to the 2.1 "update"
Since the update I've had loads of issues.
-Occasionally (upto once a week) everything will vanish. All my apps, my menu is empty and my home screens are empty. I tried changing to pro Launcher but it didn't make any difference. While in this "mode" I can use the phone as normal as long as the app is already open in the background. To fix it - reboot the phone.
-the phone is generally slow. It hangs loading the phonebook, the menu and general UI is slow and lags when doing anything including making, receiving and ending phone calls - and sending texts.
- Occasionally (at least twice a week) my phone will not send a text, ie I have to "resend message".
- Daily (at least once a day, when I notice it) the phone will decide to drop all network communication for no reason. One second I have 4-5 bars then all of a sudden a X appears over the status. It only lasts about 5 seconds and has not actually bothered me because it dosn't seem to happen in call but it's strange.
The major issue is that it's generally slow and sluggish.
I have: Re-installed the OS twice to no help. It's even slow and sluggish with nothing installed apart from the default SE stuff.
So, firstly is this normal? Also, can I just install another android version (eg one from HTC or something) onto the phone - Android is all open and happy so I assume this can be done right?
Thanks

Does anyone else's Sensation crash periodically?

I did a quick search and didn't seem to find anything for 'crash'.
I've had my phone since the July 5th release date in Canada and since then it's probably crashed 6-7 times.
I can never tell what's crashing it (each time felt different).
once i specifically started noting what crashed it, one was in the middle of writing an email in the Gmail app when I hit backspace. Surely the Gmail app that came loaded with the phone isn't crashing it?
Another time I was just exiting an app via the back button and the screen turned black.
The other few times I don't recall.
Is anyone else experincing this? Is there any type of debugger or crash log for the phone? If no one else is experiencing this, it stands to reason one or two of my apps are crashing the thing.
I've got the Bell Sensation, too, and I'd have to say it's crashed about the same amount of times. Each time, I send the report to HTC. The app is called "Tell HTC", it comes up automatically in the notification bar.
One time it was the camera app that I was in when it restarted, another time I was viewing the calendar app. It's a phone that's only a few weeks old. Hopefully after the first OTA or two, the phone will be less buggy.
I came from a Motorola Atrix, and even after the updates, it would still periodically restart/crash. Boo.
This doesn't really help you, but just wanted to let you know it's not just your phone!
My phone has only the camera & screen issue, when battery is to low and I am capturing my sensation restarts. also sometimes I have some lines on screen. but my phone never crashed yet, I have it since 25 June...
Seems like it's mostly the T-Mobile and Bell variants that have the most issues.

[Q] Random Reboot

Hello,
last week my HTC Sensation started random rebooting. Sometimes it lasts longer alive (up to 15 minutes). Though what is interesting, is that my SMS Icon has (1) on it, while after opening the native SMS app it does not display anything, nor I am able to recieve any more SMS (aaand usually it crashes after I open the SMS app).
I do not ever delete my messages (well ... why should I?)
Could it be, that there is some SMS hack which causes the stock ROM to crash?
the phone is not rooted (except S-OFF, which I did just to see if it goes), no crappy apps installed, running only stock ROM. Since 2 months I am not able to install HTC Twitter client (it reboots and I get a blue Android with an exclamation mark and cannot do anything more) and on my SD Card I have ~160MB Free - could that an issue aswell?
Edit: the phone heats up like crazy
It's because the phone is overheating. I have the Xe and it's a nightmare: usually just take the back off, and take the battery out for ~10 minutes and put everything back in.

tried that, doesn't work
had the battery out for 4 days already, even the time settings had been reset.
Curious though: it started rebooting after first day I went skiing with this phone (wanted to do some Runkeeper stats). Outside temperatures never dropped below -10 celsius - could that cause the issue
Have a look to see what free memory you have on the phone and on the SD card, if the phone memory is getting low (below 40 mb ) or the sim memory is low (below 400 MB) then its time to do some hasrh house keeping
SD card is simple if you can replace it with a bigger (and faster version)
If its phone memory, a factory data reset is the simple way around it then use something like App2sd to keep the phone memory free
Lack of free memory is the number 1 problem for freezing and reboot issues into our call centre for android phones
Ooh if I were you, I'd delete those text messages. I save mine as well using SMS to Gmail Backup and have a limit of 70 SMS messages and 5 MMS messages. The rest of it gets backed up.
I don't know if I'm right or wrong but from experience.. saving ALL of those text messages up can slow it down. I saved up to about 20,000 with one person and it was pretty slow. (This was back then when I had an older phone though) However! Deleting it did help. I wouldn't suggest keeping all your messages... imagine if you had a million and the SMS app had to open up and load a million messages. that would take forever, and in your case, might not even work!
Seeing as how you save all those texts... I also doubt that you've wiped your phone. I suggest 1) delete your messages (or back them up) 2) factory reset if it's not yet working properly!

[Q] Phone unusable since Lollipop

Hi
I updated my Nexus 5 to Lollipop via the autoupdater and while I initially disliked the look and how really counterintuitive everything suddenly was, it has now become practically unusable.
For starters, apps crash all the time. Simply using Chrome or UC browser results in a crash back to "desktop" every few seconds and when the browser is reopened it is back to the main page having lost any tabs etc.
This also happens with other apps such as the music player which closes and when reopened my audiobook is reset back a random amount.
When this crash happens, I find myself on the main page of the phone but it is totally blank for a few seconds until it jerks right, then left and some app icons appear and then freezes a few more and the rest appear, as if it has reset.
I have today discovered this 'crash' happens even when the phone is locked now as my wife tried to call me and got VMail so sent a few texts which I didn't get til I unlocked my phone and experienced the same blank screen and slow reappearance of apps and finally a missed call and 3 texts.
All in all my phone is pretty useless now. Any apps I run inevitably crash and unless my phone is unlocked I cannot receive calls or emails/texts.
Any ideas or plans for this shambles to be fixed?
Thanks
Easy to fix - wipe it and flash a factory image...

Samsung Interface Not Updating

All,
First time poster, frequent visitor of XDA Forums. I've come across an odd issue that I don't know how to solve and I'm hoping some of you smarter than me folks can get me squared away.
I have a Galaxy S8+ from AT&T running Android 7.0 and Samsung Experience 8.1.
Problem:
I've recently noticed a delay or completely non-updating interface on my phone. It updates on occasion, but I can't determine what triggers an update. For example, I will pick up my phone from the desk and when I press the power button it shows the accurate time. When I unlock the device, the sense flip clock I use on the main home screen shows an earlier time (could be 30 minutes... could be a few hours). I don't believe it's just the Sense app because I noticed this issue where I checked a facebook messenger app that came and and when I closed the app, it still showed I had 1 notification. I went back in thinking I had another new message, but I didn't. So it was still hanging on to the notification. It happened a couple times with a text message as well. Most importantly, my calendar doesn't alert me prior to an appointment either, even though it's showing in my calendar and an alert is active. If I save an event, and exit, I can normally see the event appear on the on widget immediately as well... but that hasn't been happening. I have to press the widget to open it and confirm it is there (which it always is). Eventually it refreshes and shows up. But that delay is likely the reason why I'm not getting my alerts.
All of this did seem to happen after a recent update Samsung/AT&T pushed out but I don't know for sure. I tried clearing the cache from the boot menu but it doesn't seem there is wide success with that.
And perhaps I'm just not a good enough user, but everything isn't all backed up in the cloud so doing the factory reset to me is always a fairly large task as I have many things to manually transfer out and then back in. Not sure if there are great tools that help with this on a stock phone.
BUMP
try disabling battery optimization for those apps.
It seems that you have several bugs and if they all start happening after you have installed the latest update, then expect a patch coming soon.

I have actually done that. Found very limited success. I'm also finding very few results on this topic. Surely it's not just me though.
And I'm dreading the idea of a hard reset as I have many things on my phones, not all of which is sync'd to the cloud so it's a task to back things up appropriate. Specifically regarding "encrypted" apps like my password keeper app etc.
It would be great if there was a software application that allowed you to backup whatever is necessary to not lose data, then wipe the phone and instead of just simply restoring the full phone (which is likely to create the same problem one had before the hard reset), you could simply dump back in app data as needed. It would also help diagnose if the problem lies in a specific app's data.
High level overview of issues...
I have the Ring Doorbell app. I get notifications after "live". Could be 5 minutes, could be 1 hour... or possibly not at all. I have the app setup on my wife's iPhone and she gets them immediately. If I restart the phone, I will get notified right away (it's like it runs the app again and then I get the notification). Keep in mind, this is AFTER i disabled the battery optimization feature for the Ring app.
I also notice it occasionally with texting. I won't have any text notification in the notification panel, nor will my messaging icon have a little red circle indicating a message is there. But if I open the app, a specification conversation will have a red circle indicating a new text is unread.
All of this is leading me to believe the Samsung UI itself is not updating and therefore notifications that actually have arrived (from whatever app), are not displaying because of the UI and not because of their own delay.
Because of this concern I have turned off battery optimization for "System UI", "Themes", and "TouchWiz Home". I have not seen any change however.
[Solved]
I was able to determine by various other threads around the web (thought for sure I'd find it here, but I didn't) that the culprit might be the Google app. Supposedly it was fixed in some prior release, but it's not on my Galaxy S8+ w/ AT&T.
Once I disabled the Google app all the odd issues with notifications and clock interfaces and app icons not updating went away. The downside to disabling it is that I lose the Google Assistant functionality which stinks but otherwise there is no impact to using the phone. I re-enabled it at a later date and it worked fine for a few days and then started acting up again. Once I disabled it, the problems all disappeared. Clearly Google app is to blame.
