Currently, the forth beta iOS 9.3.2 is available for testing to public testers and novelty users and it supposedly comes with many bug fixes as well as with the ability to use Low Power Mode and Night Shift simultaneously.
This release is part of a series of update releases that came in the past few weeks beginning with the iOS 9.3.2 beta launched on the 6th of April. The purpose of the first beta was bug fixing and improving performance relating to the iOS 9.3
Other issues that were solved by this beta was a lag experienced by iPhone 6S users when the activated Quick Actions in landscape mode.
The second beta came after a week but it was very subtle about the changes, although, some phone users reported that they could enable Low Power Mode and Night Shift at the same time
The third beta appeared to be just as uneventful as the previous one. It had about 32 MB and had the number 13F65.
The last and forth beta version will cover a variety of bug issues related to the Game Center. One of those bugs rendered a white screen at some point, and reportedly, with this problem now fixed, users will be able to read anything from web pages too e-books at night without much difficulty and without using the same amount of power as before.
Before this last beta, users had to rely on just one of the following options: Low Power Mode and Night Shift because the system would disable one automatically is the other one was turned on. Now, because of the update they can be used at the same time.
Anybody can now go to the site and download the beta for use but know that you need to pay for the account to get full access to it.
