April Security Update Ready

Updates often had an "optimising apps" stage on other phones which would happen after the reboot (and could be slow). I think the Pixels, with their A/B system partitions, do all of that stuff before the reboot.

It was never that fast on my Pixel 2, but as you could carry on using the phone while it was all happening that wasn't a big issue.

Thanks for the info, Hadron. Its the same with the Pixel 6 Pro. You can use the phone while it's optimizing.

Help Lose mobile data when leaving wifi signal.

Odd that using Reset Network settings didn't help. If you take a look at the selected APN entry buried in your Settings menu, does it resemble these Tesco parameters?

Do both your phone's APN options and Tesco's posted APN options match exactly?
The Tesco APN should be automatically added when you insert its SIM card but as is but if not, perhaps there's just some glitch that involves some kind of discrepancy. Try creating a new APN entry using those posted parameters, select that new entry, and restart your phone. Hopefully that helps fix your mobile data problem but if not, you can always just select the original APN entry.

Thank you for your reply, I have used different sim cards and the same problem occurs, it is a problem with the phone.. When I use the simcard(s) in another phone, there is no issue.

Given you've sent this phone in to be serviced elsewhere and if you're certain the SIM card is OK, after all the the other things you've tried it might be time to just set this particular phone aside and get a new one to replace it. Hopefully it's still new enough that there's still warranty coverage so you can use that money to help cover the costs.

Help Outbound calls immediately ending / Inbound calls going to voicemail

This might not necessarily be a problem with your S8 but rather with your carrier on their end. If you have access to another phone (friend or relative?) try putting your SIM card in that phone and see if the call problem is still so quirky.This test might help determine if the problem is with your phone or your carrier.

Looking up Red Pocket online, it isn't just a MVNO tied to one cellular carrier, it's a MVNO that's contracted to use AT&T, along with T-Mobile and Verizon. If you do contact them about a new SIM card (which might be good to do anyway) you might also want to have them send you a replacement SIM for a different carrier. Depending on where you live, you might want to switch. Try installing this OpenSignal app:
https://play.google.com/store/apps/details?id=com.staircase3.opensignal&hl=en_US&gl=US
It's primarily a bandwidth speed test utility but includes a handy map feature that shows local cell towers for the major carriers, and crowd=sourced data on approximate speed numbers. it might help determine which carrier has better or worse coverage where you reside.

Custom ROM installation assistance

I have rooted a few phones in my day, but I've never installed a custom ROM, so here's my situation. I have a Galaxy S4mini (SPH-L520) variant. It is currently rooted, but it still has the old KitKat Android version, which I think is 4.4.2. That version is proving outdated to the point of being ostensibly useless. Play store crashes. YouTube won't update to a version that works. The list goes on. I use this phone as a universal remote, because Samsung only had the IR blasters in the Galaxy 4, 5, and 6 series. I'll never understand why they discontinued this excellent feature. If I want to continue using this phone for my purpose, it's time for me to bite the bullet, and force an Android update, and I've been working on it for hours now, to no avail. Again, the phone is rooted. I have Odin. All of the sources I've found keep steering me to mediafire to acquire the ROM, but all of their downloads contain file types that are not what Odin requires, such as .tar, .md5, .smd, .tz, and .tgz. Google searches keep directing me to flash the stock firmware, which is obviously not my desired result. The videos I'm seeing aren't helping either. Obviously, I'm doing something wrong, or overlooking some key detail. Can anyone point me in the right direction, please? My email is [Removed] if that makes communicating easier. I look forward to any help here.

I'm pretty sure with an S4 Mini, there is no ROM version higher than Kitkat 4.4.4 made for that phone, either custom or original Samsung. Think you can just keep it as an IR remote control, and not much else. I have a Huawei Mate10 I keep around, and I often use that as a remote control for TV, Android box, and A/C, as it has an IR blaster.

Autofill service not shown in settings autofill service list

I don't expect functionality to work, but shouldn't this be listed in service? Please suggest if I am missing anything.

I have added Service tag in AndroidManifest.xml

Code:
<service
           android:name=".MyAutofillService"
           android:label="My Autofill Service"
           android:permission="android.permission.BIND_AUTOFILL_SERVICE"
           android:exported="true">
           <intent-filter>
               <action android:name="android.service.autofill.AutofillService" />
           </intent-filter>

</service>

MyAutofillService class looks like this,

Code:
package com.example.myapplication

import android.os.CancellationSignal
import android.service.autofill.*

class MyAutofillService : AutofillService() {
   override fun onFillRequest(p0: FillRequest, p1: CancellationSignal, p2: FillCallback) {
       TODO("Not yet implemented")
   }

   override fun onSaveRequest(p0: SaveRequest, p1: SaveCallback) {
       TODO("Not yet implemented")
   }
}
Added code to start service, I can see it's started.

Code:
startService(Intent(applicationContext, MyAutofillService::class.java))

Only thing that is not happening is it's not listed in Autofill service list.
