LG G2 review half a year later - massive memory issues

It was the Phone of the year when released and indeed LG G2 sports some fabulous stats. It looks good, feels good, operates good and overall was a great mobile phone vastly superior to my favourite line of Samsungs I've been using before.

One thing I have overlooked was the lack of memory card slot. But with 32GB storage and 2GB RAM this seemed not to be a problem. Wrong!

A several months of using it and I run into such massive problems that only a full factory reset and following careful application grooming helped me regain control over the device.
It must have been a more common problem, because newer LG G3 already has a memory slot.

What were the symptoms?

1. Tapping stopped waking up display. - I thought... oh well this is nouvelle, maybe it wasn't tested for that many taps and it died... I can survive it. Yes I am that lazy when it comes to call service desks :D
2. Phone started getting very slow, then gave me a message that it has full memory. - I have promptly removed almost all of my photos (quite a lot of them), all videos, all downloads and documents. And it started working, but still quite slow. I kept checking for syncs, missed data. Old applications storage... Nothing helped.
3. Waking up the phone took a trial and error approach, it would sometimes wake up after pressing the buttons at the back, but most of the times it would not. When it would it would tell me I have no connection, while on WiFi and full bars, or would just display completely unresponsive screen and then time it out and die.

After a lot of tries I have decided to connect it to my computer (while it still sort of worked) and in a painfully long process (it kept hanging and disconnecting) back up all my stuff (yes LG backup stopped working) and perform a factory reset. My reasoning was: If the phone is broken the problem will manifest itself with only a handful basic apps within the first week. If not, then it must have been one of the applications.

I was wrong. After gradually adding applications I noticed that LG G2 can't gracefully handle a lot of installed applications. Many processes running in background, a lot of cached data will pretty much brick it.

At this point it seems like the only solution is to keep number of the installed applications managed. And to be honest for me, who uses a lot of applications on daily basis this is a no go. I need to be able to keep more than 40 apps on my device. And currently this seems to be the level my mobile handles OK. It may be different for other users, because not all applications are the same, some don't run processes, some store less data.

Another option is to regularly delete application cache. Also not perfect. I like some apps to keep my data, it makes it quicker to work with them.

With no option to expand memory I am now just waiting until my contract is finished so I can replace this phone.
