What happened after ios updated the white screen?

The reasons for the upgrade failure may be:

1, no experience qualification for ios 10 beta.

2. Check whether the capacity is insufficient 1.9G and network problems.

3. There is something wrong with the fingerprint

Update failure is mainly the first two problems. Bian Xiao also told you the solutions to the first and second problems today. If it is the third reason, just change the fingerprint password into a digital password during the update process!

Question 1: How do I get the experience qualification of ios 10 beta?

As a fruit powder, the developer's qualification is really hard to get, so where is the difficulty? First, you must register as a member of the Apple Developer Program. You can choose personal identity or corporate identity. Secondly, the annual fee for personal identity is $99, while the annual fee for joining the Apple Developer Program as an enterprise is $299 (subject to local currency).

So it is conceivable that it is not easy to have the right to upgrade iOS 10 Beta 1, but in July, Apple will provide iOS 10 Beta to all users.

In fact, it doesn't matter if you don't have the experience qualification of ios 10 beta. Just copy the download link of ios 10 firmware on your mobile phone, and then click Apply Safari to enter the following installation program to complete the upgrade of iOS 10 Beta 1. After the download is completed, you will be reminded to restart before installation, and click OK.

Question 2: What if the capacity is not enough 1.9G?

For users with insufficient capacity, it is necessary to reasonably clean up the memory of the mobile phone. Here are five ways to clean up Apple's space memory.

1. Turn off the permanent storage of SMS.

By default, your iPhone will permanently save all sent and received SMS messages. If you want to view the conversations before1May, this function is very practical; But if you want enough body space, you'd better turn it off.

Go to Settings, click Information, slide down, click Keep Information in Information History, and change the default "permanent" to "30 days" or "1 year". After clicking, a prompt will pop up asking whether to delete the old information. Click "Delete".

2. Don't save the photo twice.

If you often use the iPhone's HDR camera mode or Instagram, you will find that these photos have been saved twice: the HDR version (or the filtered version of Instagram) and the normal version.

So, how do you turn off HDR photo backup? You can first select Settings-Photos and Cameras, slide down and turn off the "Keep Photos Exposed Normally" function.

At the same time, you can open the Instagram application, click the profile, click the gear-shaped "Settings" icon in the upper right corner of the interface, and turn off the "Save Original Photos" function in "Settings".

3. Clean up the browser cache

If you often use Safari browser, you may have saved a lot of webpage history and browsing data in your iPhone. You can clean up these contents by clicking "Clear History and Website Data" in Settings -Safari.

If you are using a Chrome browser, you can find "History" in the menu bar in the upper right corner of the application, slide to the bottom of the page, and click "Clean" to complete this operation.

4. Clear offline data

When you use those online applications, you may also inadvertently store a lot of offline content. For example, Safari browser will automatically save some content for offline use when you browse online, but in fact it will only take up unnecessary space. You can open Settings-General-Use-Manage Storage Space -Safari, and click the offline reading list to delete the data.

Music applications such as Spotify also save recent playlists. You can open Spotify, find the playlist you don't want to go offline, and turn off the offline function. In addition, at the top of the playlist, you can also find a function to switch off-line availability, and click Close.

5. Selectively delete applications and data.

The above tips can only make room for the mobile phone, but if you want more capacity, you need to delete some more "real" content, including applications, videos, photos, blogs, music and so on. You can view it in Settings-General-Use-Manage Storage Space.

In this "leaderboard", you can know which content occupies the largest mobile phone space. If it is a large game, then you can choose to delete it; If it is a photo, then you should consider exporting some photos; If it's music, you'd better delete some albums and songs.
