This is the wrong phone for you. Android is too finicky for many when they hit storage issues like you noted. Time to shop for either an Android with a lot more base memory (my LG G4 starts with 32GB of base memory so I avoid all the troubles you listed here.
In short, wrong phone.
Having lost my "simple" mobile phone, I was given a ZTE Blade L3 "smartphone." (I am not coping with it at all well!)
ZTE Blade L3
Android version: 5.0.2
Android Security patch level: 2016-01-01
Baseband Version: MOLY.WRB.W1449.MD.WG.MP.VI.P21,
Kernel Version: 3.10.54
Build Number: DIS_ES_B18DL_P182A20V1.0.4
It came with many apps already in it and after having assistance to download - Gmail, Yahoo, Notes, AVG Cleaner, Unit Converter and WhatsApp, there remained only 237MB out of a total of 2.13GB in the Internal Storage, which it seems is the mandatory location for any downloaded apps.
Being completely non-technical and also well past my sell-by date, I bought an SD card. I moved what apps that I was 'allowed' to move to the card and now there is 14.13GB available from a total of 14.83GB, hoping that I could use that - WRONG!!
I get the no available space notice and am not able to download anything any more.
I have a total ‘phone’ storage that is 2.75GB with 2.47GB available.
How can I either increase my Internal Storage to allow apps to be downloaded or how can I enable downloads to go to either my Phone Storage or my SD Card storage.
I would note here that the "Default Write Disk" options of Phone Storage and SD Card, make no difference when clicking the circle which produces a "dot" inside the circle alongside the name, downloads do not go to the chosen disk. So what does “Default Write Disk" really mean?
My second problem is - I don't know if I am allowed to include more than one question, please advise me if I should make these into a separate questions - is that if I open a newsletter from - for example, CNET - that has choices to click open an article, when I try to open the article my phone throws up a notice of -
"Security Warning - There are problems with the security certificate for this site." beneath are choices - "View Certificate" "Go Back" "Continue."
If I click "Continue" it repeatedly returns and blocks me from seeing the article.
How may I disable this from happening. For me, this is a trusted site which I have been going to for years on my pc.
Lastly, (Here, I imagine a sigh of relief!), could some kind soul explain in simple words what “Data Usage” really is.
As an example I shall use the figures that I gathered this morning.
Before I went to bed last night, Data Usage showed as 32.62MB and Battery Charge showed 95%. I cleared all the cache in every app, turned off the WiFi on the phone and put the phone to ‘sleep.’
This morning on opening the phone the Data Usage showed 32.66MB, Battery Charge showed 93%.
The following apps showed the following amounts in their cache –
AVG Cleaner 1.68KB: Google App 608B: Google Play Services 267KB: Google Play Store 17.3B.
I realise that KBs and Bs are infinitely small amounts, but how would they have accumulated even the smallest amount. Also, I clean the cache of the apps at sporadic times and often find there are some with many MBs showing. Many I do not even use like the Google Play Station and Play Store and Google maps, but they frequently show large amounts of MBs in their respective caches.
So basically, what is the cache and how do MBs enter it when it is not even used?
If the answer(s) are technical, please write the details in simple words!!
