You avoided the question (and, in fact, you avoided the topic).
 
Organizing a phone is no different than organizing a toolbox.
It's no different than organizing a closet.
No different than organizing a kitchen utensils drawer.
 
A place for everything, and everything in its place.
 
Given that, I'll repeat the two simple questions here:
1. How do *you* organize your phone?
2. What apps do you find are *best* for what you do?
 
Specifically:
1. How do *you* organize your phone?
(Please show a screenshot so that we can learn from you.)
 
2. What apps do you find are *best* for what you do?
(Please suggest a best-of-the-best Android app for what you do.)
 
Thank you for your kind advice.

Do you think anyone really gives a rats ass
about your phone? How fucking big headed of you.

Owner decided to power up on full 240V mains after being in an English
garage for many years. Worked perfectly before "storage" and well for a
few minutes and then arcing and sparking crackling noise so he switched off.
3 amp mains fuse ok but at half mains on a variac taking about 1 amp
with all valves removed. I'm assuming the excess current draw does not
disappear at 100% mains, I've not tried, but about 1.2 amp at 50% and
not distressing let alone blowing 3 amp at 100% before my powering,
curious? Unusual, for these days, winding pattern,? no magnetising buzz
heard at 50% mains or other any odd noises.
With variac "mains" of 34V ac, secondaries give, multiplying by 240/34,
465V, 6.3V, 5V, ie ballpark values . "HT" is ratioed 27 to 39 V ac wrt
ground, but 27+39 multiplies to 465V .
I've not desoldered the mains Tx primary or secondaries yet, but what
could be the failing in the Tx to give otherwise good scaled outputs.
There is a lot of tar leaked out of the Tx , but that was in antiquity
presumably and normal.
HT caps and o/p tx have been replaced at some time and a dummy load/sp
attenuator added for recording

Where are you geographically ? I don't know what that other dude is talking about with this "why are you treating him this way ?". It is a legitimate question.
 
Let me tell you some true shit. I am in Cleveland, Ohio and I fixed a stereo for a guy in Pittsburgh, Pennsylvania. It was a kinda heavy bulky thing and cost $300 round trip on UPS, AND THEY FUCKED IT UP. And in an insidious way that would be so hard to prove. So he gets ahold of me and we talk, he emails video of what its doing and pictures of a part that fell out and then we met, pretty much at the state line. Little bar off the pike and can whet your whistle a bit.
 
Bottom line, if you want to ship two betamaxes it is not likely to be cheap. And if you need belts, let's just say the days of the five buck belt kits are over.
 
If the Sanyo has the mech I think it has it will need a super small belt and probably idler. I would guess they are not that great of a deck, but if the heads are good they are worth fixing if you can get the parts. And of course now there are 3D printers if you peel off enough green. Actually you have to glue the thing together and they have to go in a program like Solidworks or something and fix it. THEN it gets sent to the 3D printer without the line in it from where the glue was. And you have to learn this software, it doesn't just do it automatically. Friend of mine does something similar and figures he should be able to do it with the software on his PC, which is Rhino, which is supposedly better than Solidworks.
 
But they got a specific file type for that. I forgot the extension but it is kinda standardised.
 
Now, this (SL)2700. That is a hifi deck correct ? By that time I do believe their mech used that much coveted reel motor assembly that allowed them to go into reverse immediately. If your reel drive runs off of your capstan motor you need a tape slack pickup routine every time the customer pushes reverse search. With a separate rell motor that is not a problem.
 
Problem is something started happening to those motors and they started pulling alot of current. And back then $70 for the motor itself, and the is net dealer price.
 
You knew by this one transistor failing time and time again. The only thing you could do now is to modify it to supply the current. But in time, how long will the motor take it and how long will the power supply supply it ?
 
No matter what this is not going to be cheap.

Do you mean the specs that are printed on parts - like relays - should
be respected?
 
What an odd idea!

I am old and have funny notions like that.
 
But I do have to admit to putting foil on the fuses in my amp so it could drive 2.3 ohm loads. One eight ohm and one four ohm per channel in parallel. Actually, never blew the outputs, it didn't even get that hot. Sansui 771.
