I'm looking for an app that tracks when the SIM card has been removed and inserted. Does any such thing exist?
Best lockscreen apps? For showing message details and the like?
Maybe looking for something to emulate the iOS experience, any ideas appreciated, cheers!
Been accepted into the new Waze Beta testing program!
Cerberus tells you if an 'unknown' or 'unregestered' SIM is inserted!
Pry-Fi will prevent your device from announcing all the networks it knows to the outside world, but it will still allow background scanning and automatically connecting to Wi-Fi networks. While you are not connected to a Wi-Fi network, the MAC address will constantly be pseudo-randomized, following a pattern that still makes the trackers think you are a real person, but they will not encounter your MAC address again. This will slowly poison their tracking database with useless information.
as far as i understand having apps on the system hd or the sd card wont increase the speed the phone runs, if anything it may be slower if the sd read speed is less then the hd one. i may be wrong though but i'm 90% sure that's the case. hard drive location doesn't have anything to do with speed, as the location and size of your fuel tank doesn't have anything to do with engine speed of a car.
maybe he has bad apps on the phone?
This. Due to an SD card's slower read/write speed apps on the SD card will feel slower.
As for moving apps, if you don't have the option of doing so under settings, then you will need to be rooted first.
I would consider perhaps rooting it and using a custom ROM if you want more performance. I'm assuming the SM-T210 is the Tab 3 7.0: http://forum.xda-developers.com/galaxy-tab-3
