Hi nice folks
Does this mean anything to anyone?
I have a slightly aging Samsung Tab 3 10.1 inch.
Runs Android 4.4.2 - Samsung won't update it beyond that but no matter - that is not an issue.
Battery has of course declined in power over time but the unit is far from exhausted and fine for in house use (I have a smaller tab for out of house use) and delivers over 4 hours of use before it needs to be recharged.
BUT
recently had serious problems. It very often won't start up even though I know it has plenty of charge.
When in this state plugging it in doesn't produce the on screen charging symbol either.
It can take 20 to 30 goes to get it to start - usually by pressing the power key and the UP volume key, which presents me with this list of recovery options.
Reboot system now
Apply update from ADB
Apply update from external storage
Wipe data/factory reset
Wipe cache partition
Apply update from cache
I choose the first and it boots up and all is fine.
And I can use it for hours - no sudden shut-downs or apparent power problems.
Until after closing it down it will then refuse to start next time or the time after that or the time after that.
Am mystified.
I charge it using the original charger and lead or a quality Anker smart charger and anker lead.
It doesn't seem to be a power problem as such - surely if it were, a loose connection or something, it would quite often just shut down in use?
This appears, from googling, to be quite a common issue.
Anyone got any clues?
Can android become corrupted in some way?
Will a factory reset solve this?
I have at least, during one of its brief functioning periods, managed to get all the important stuff off it and on to Google Drive.
Over to you ...
