Unresponsive / laggy UI, some apps not working till cache wiped - Huawei P20 Pro Questions & Answers

I'm on stock 9.1.0.345 (no root, no twrp).
Since two or three system upgrades I've been experiencing very laggy / unresponsive system behaviour, returning every couple of days, sometimes more often. I then have to wipe system cache partition and phone is usable again for few hours / days.
Sorry if that's known issue but couldn't find related thread.
During the issue is happening I experience randomly:
* cannot receive calls
* cannot make calls
* internet browsing is extremely slow or not loading any sites
* apps like youtube opens and loading the initial screen but cannot select any video or settings or anything, it's like frozen but can for example scroll down / up - same issue for multiple apps
* cannot play media videos - they just loading infinitely
* wifi icon dissapears sometimes
* network coverage bar dissapears sometimes
and many more.
Wondering if that could be a hardware issue (memory? flash?) or is it known issue for that specific phone? I'm about to do factory reset to see if that helps but wanted to check with you guys first.

Backup your Phone and try to wipe system data partition. Your Phone Will ne erased and i advice you to restore your apps from Play store Instead of backup

Captivate boots slow, issues. How to troubleshoot?

So, a little history...
I'm on my 2nd Captivate (unrelated issue). The boot problems didn't arise until I restored my data onto it. The first time I tried restoring system data along with my apps (which I figured was safe since I was going from 2.1 stock to the same) but that had lots of issues. So I did a factory reset, and started over. This time I just restored apps and their data, and a few specific pieces of system data (contacts, wifi APs, etc). That worked better. But later I got too aggressive with what system apps I "froze" (using Titanium Backup), and it got into boot loops I couldn't break out of. So I did another factory reset.
This time, first I carefully froze only apps I was to confirm were safe to freeze. I didn't proceed restoring my apps until I was done freezing and ensured it was booting fine. I then restored all my apps (and their data). The problem is now that it takes forever to boot... in fact, it'll go into a boot loop if I just leave it be. It seems the only way I can gain access is to try and unlock it before it's done booting, clear any "Force close" errors (sometimes takes a few tries) and given enough attempts, I can get in. But the boot takes an unbelievable amount of time, and even with my original apps is many times longer than before on my previous Captivate. Once I fuss my way in, it seems mostly fine, but something is obviously wrong and I want to get it straightened out.
Aside from doing another factory reset, and reinstalling all my apps (which takes like a day without troubleshooting after each, since batch restores in TB don't seem to work well on the Captivate so I have to do them one by one), I'm hoping there's a way to troubleshoot it in its current state and try to fix the problem surgically versus erasing and starting over. I looked at the logcat logs but got in over my head... there are so many errors and warnings and I don't know what's normal and what isn't... too many to know where to begin with searching Google.
So... advice? What tools are available? Even the logcat doesn't seem to kick in until the boot is mostly done, so I'm not sure if it can catch the problem while it's happening. One frustrating thing about Android is that is seems to have no "safe mode" or other diagnostic boot or full logging where you can methodically look at what's happening and experiment with the config. If this was a Windows, Linux or FreeBSD box I'd be in my element and able to get to the bottom of this, but on Android I feel even more crippled, locked-out and helpless than even on Windows. Urgh.
There's got to be a better way to troubleshoot and fix than endless random factory resets. This is something us anti-Windows people scold PC makers for, with all their use of "Restore CDs" for every minor and trivial software issue.
Thanks!
I can't help but think you are still disabling some essential system apps. Either that or one of your apps is causing major problems. Please list what you have frozen in tibu. Btw, the batch function works fine and is what most people on here use.
Also, what is force closing after you restore your apps.

First of all, thanks for taking a stab at this.
My frozen apps are:
* AllShare
* AT&T FamilyMap
* AT&T Hot Spots
* AT&T Maps
* AT&T Music
* AT&T Navigator
* AT&T Radio
* Daily Briefing
* Days
* Instant Messaging
* Media Hub
* Mini Diary
* Mobile Banking
* Mobile Video
* MobiTV
* Where
* Write and Go
* YPmobile
I also tried removing my MicroSD card, as well as switching back to Touchwiz (from LauncherPro). Didn't help.
Yeah the batch problem in TB is very frustrating. I'm using the pay/donate version so I'm missing out on a feature I paid for. I've been exchanging emails with Joel (the author) and we haven't figured it out yet. Batch backups work fine. Batch uninstalls also work fine (update: phone just spontaneously rebooted after about 50 or so uninstalls in a batch). It's the batch restores that seem to choke it. It's not corrupt backup files... a verify runs fine, and I can individually restore the same handful of apps one by one that will choke and hang/reboot the Captivate if attempted to restore in a batch.
The FC error I get is on boot-up, as I try to unlock the screen prior to the boot finishing. I often see "Process system is not responding".
I have aLogcat installed, if that's any use. A few questions about that:
- What's the best logging level to view on? In other words, do I care about "Warnings"?
- What errors are common, harmless, and safe to ignore?
Currently I've tried uninstalling everything down to just a few core apps. Certainly boots fine now, but I get plenty of warnings and errors in logcat.
Are u restoring just the user installed apps+data, or system apps too? Or restoring system stuff like contacts data, accounts prefs, etc?

I did not do a "restore system data" or any batch/bulk option in TB that restored all system data. As I recall, the only system data I restored a-la-carte (by selecting the individual item from the TB list) were:
Accounts
Bluetooth pairints
Bookmarks
Calendar
Contacts
Wi-Fi Access Points
These were all items in green in TB. I don't believe I restored anything else. Possibilities I suppose are wallpaper settings, "Country, Launguage, Time Zone"... but I definitely would not have restored anything not green.
Are these items safe? Is there any system data definitely not safe to restore? I have to wonder though, if "system data" is unsafe to even restore to the same stock OS version... why back it up at all?
I'm not a long distance from doing yet another factory reset I suppose, if it must come to that. But I'd love a way a bit more analytical/exacting to try and troubleshoot this other than "reinstall one app, reboot, see what happens" as that will take me a week to get back to where I was. I also suspect it's not just one single app that would suddenly show a huge difference after installing, but instead might be the cumulative errors from several apps and knowing how to identify that and clean them up would be useful.
Using adb logcat you can view what is occurring while the phone is booting and possibly see where it is hanging or what is causing the slow boot times. I have seen problems from restoring data such as accounts and contacts with titanium backup but does not seem that it should be an issue when using the same system though I have very little experience with the stock firmware. I know it is not an answer to your question but it seems that you are wanting to remove all the att/Samsung BS so why not flash a rom that does this as well as much more?
Sent from my ADR6300 using XDA App
Thanks for the tip about adb. I've actually not needed adb for anything yet so I've never set it up or used it. I wasn't aware that the service would be active early enough on the phone's boot process to allow it to log boot logs... nor was I even aware it could do this. I'll definitely check out how to set this up... however, if you have a free second and can point me in the right direction (FAQ, instructions, etc) it'd certainly be appreciated otherwise I'll search around and try to find it.
I could probably find other ways to restore contacts and could set my accounts up again manually but I really doubt that's the cause and the other ways are sort of a pain and imperfect. Since neither of us is really convinced that'd be it I won't bother yet until/unless you really suspect it.
I wondered how long it'd take before someone would suggest a custom ROM, this being XDA and all. Short version is I'm not really sold on the concept, as they are all based on the buggy beta leaked ROM, or 2.2 ROMs from other devices that have been hacked up to sort of work as well as possible on the Captivate. All seem to have issues... enough that I'm not really left feeling confident about them. Seems every release unleashes new issues despite addressing old ones, and all seem to have at least a handful of gremlin items that just don't work quite right. Don't have a warm fuzzy feeling, and I still feel like Samsung is going to release an official 2.2 for the Captivate within the next month or so, so I'm interested to see what comes of that. If nothing else, it'll give a better baseline for custom 2.2 ROMs. Then there's the 2.3 being worked on... now that might be interesting.
I don't really think my issue here is related to me running 2.1.
On my phone so it is a pita to search and add a link for you but search for android sdk and you will find what you need to get adb up and running.
And as far as the rom issue goes..it is your phone and I respect your concerns I just had to ask
I would think its media hub that slows it down. It will search your SD cards on every boot. I would start there first.

That's one of the apps I've frozen though.
For me the longest process while booting is the stupid media scanner upon bootup. Takes FOREVER for the phone to finally "boot" all the way up.
Been looking for a way to disable it (not really lol) and only have it scan manually to see if the boot time will improve. I'd start searching there.
Also - from what I've read nothing you did should have affected the phone. BUT - if your using Google for your Calendar and Contacts.. and they all get synced up to Google? Why bother doing the restore for those? After you sign up with the Market they get pulled back down to your phone automagically
It's definitely more than just the media scanner. I watch that. When everything is loaded up, it actually reboots in a loop unless intercept the FC. The media scanner will rerun over and over each time... far more than the standard two times.
And I use Google Calendar for my events, but I keep my contacts locally on my phone.
So what is the FC again?
Yep.. my media scanner will run at least 3 times before it stops checking everything.
Very frustrating that the software does this EVERY time I boot back into my phone - you'd think a programmer would put a check to see if it had run before or make it user configurable to scan when you want it to.

See my second post (reply #3):
"Process system is not responding"
LOL sorry not enough coffee and a lil' guy that decided to wake up at 4a.m. = not a good mix.
Well.. did the ol' wise search of Google and came up with:
Might be a permissions issue. Easiest way to fix it is to run ROM Manager and have it fix permisions.
Run the command yourself in ADB:
Code:
Open terminal and
>su
$mount -a
$fix_permissions -r
The -r is optional, but necessary if you find orphaned apps (the app not found please reinstall message)
And reboot. That may help.
And it was also stated that you might have an errant widget/application causing the issue as well. That will be fun trying to figure out what it is.
And.. from my non-dev/non-professional experience - I have checked the logs on my phone and do see a large number of warnings on the phone - but never hindered performance.
So.. 99% of the time you can probably ignore them.
But back to the FC issue - I would try doing a restore of your apps/data again (I read where you have it back down to the "core) and then run the permission script or have ROM Manager do it for you and see if it returns.
Just an update that I think the "fix permissions" thing solved most (but perhaps not all) of my issues. Thanks so much for the tip. I've been reinstalling apps in batches and it's much better, although I see it getting bogged-down bit by bit and I can't pin down what or why.
Thing is, the apps I'm installing in these later rounds/batches shouldn't be resident all the time, shouldn't be auto-loading, and don't come up in things like Startup Cleaner or Advanced Task Killer. Nor do the various process monitors I've tried seem to have the granularity/ability to catch them while they're happening.
So things are better, but I still have some issues without a suitable means to diagnose. I don't get why just having more apps installed, but not running, should affect boot time so much. Hmm...
An inability to troubleshoot certainly rains on my love-affair with Android... not that I'm jumping to another platform anytime soon, but I really want this to work well (as well as be a good salesman to friends and family who often turn to me to show off quality technology).

[Q] Severe Lag issues with stock GB ROM - how to diagnose?

Hello!
Recently I am having a problem, which started with only the calls being "lagging" - meaning, that I press the green button to dial (or swipe the finger left to right) and the phone would wait anywhere between 3-10 seconds before it starts to actually dial the number.
Later, the problem worsened - now sometimes it would take even 30 seconds, and in addition - when exiting applications (even light such as EZ PDF reader), I would stare at an empty desktop for around 10-20 seconds, BEFORE the icons start loading
This is not funny anymore.
Any suggestions as to how to go about diagnosing the cause?
You could try using an app like Watchdog to monitor which apps you have installed that are using too much CPU, Then uninstall / disable it
Or you could try a full wipe from recovery (Need a safe kernel) and see how things go that way, If you have a lot of added mods & tweaks installed they can eventually start to conflict with each other, So thats also something to look into

Can you please link to the app you are talking about? Market has a lot of apps called Watchdog.
And waht do you mean do a full wipe needing a safe kernel?
As I said, I am still on the stock GB 2.3.6 ROM - if I am to do a full wipe, might as well stop waiting for Samsung update for my ROM and just install one myself, no?
My point is - how to debug and resolve this problem without resorting to "warranty voiding" actions? There has to be a way, no?

Fix for most problems without full factory reset.

Fix for most problems WITHOUT Full factory reset.
This should help fix problems on most phones with the following bugs:-
App crashes
Force close
Wifi problems
Data Problems
Menu slowdowns
Sluggish behaviour (especially after rom upgrades / downlgrades.
Battery drain
Call problems
Mail problems (sms / email)
Brightness not increasing due to heat
Poor overall performance
Poor Gps fix
Reboots
Many more improvements and fixes not listed.
Go to system settings / app settings/ all apps/ then clear data and cache on each and every app apart from contacts, But including all default android and system apps as well as all installed apps.
I know you may have a long list of apps to go through but this should and has fixed many problems for a lot of people I suggest this to.
Especially for people who like swapping roms. The only real problem is your home screens will more than likely reset to default.
Go on give it a try. Good luck!

[Q] Internet Problem, having to Stop App and Clear Cache Daily!

As the title suggests, the included internet browser app on my HTC One is frequently having to be stopped and then the cache cleared to make it work.
It'll be fine for a while then will decide to just not load anything, even if I close other tabs, the signal is full etc but the loading bar moves slowly then gets to the centre and stops. Even when opening links from emails it can happen too.
Has anyone come across this?

Question Slow downloads in Playstore (speeds up after deleting data of playstore)

Hey Everyone,
my problem is - very often the downloads from Google Play are very slow. (About 300kbit/s)
When I stop the download and go to Apps --> Google Play and then delete the Data, then open the playstore again and download the same file, it will be much faster. (at least one magnitude, about 3-8mb/s)
Any ideas?
My Wifi is the same as before and my internet-provider does provide 100mbit/s, which is being realistic about 50-90mbit/s in real life.
Regards,
Maeffjus
it seems that latest ROM updates (I think I have this on all AUB* ones) is weirdly strict on background activities and cuts every one of them. my whole device acts strangely - apps not showing notification or showing them late (hours later than they were supposed to show), my apps are not updating: I have to repeatedly FC play store, then clear its cache so that currently installing app changes state from downloading to installing, than do it again to change state fomr installing to installed etc. worked fine on AUA* ones. it is really annoying. btw I tried to clear cache and dalvik/art cache from recovery, but that did not help. I have not tried factory seset yet...
I cannot download apps or update apps. Turns out its Virgin Media (UK) blocking traffic. They're sending me a brand new shiny SuperHub 4.
It seems that it was data corruption during regular OTA. Factory reset seems to fix problems for me.
