Problem description: There are several possible reasons for this problem: 1 Mobile phone setting problem 2. The software is unsigned or the signature is incorrect 3. Certificate conflict.
Solution: 1: Go to "Program Management"-"Options"-"Settings" of the mobile phone: "Install Software" is set to-All, and "Online Certificate Check" is set to-Off;
2. Re-sign unsigned software before installation;
3: Install after the parallel machine (please make a backup before the parallel machine).
I hope the solution I found for you online will be useful to you.
Question 2: Mobile phone installation software always fails to install. Why? It should be that the remaining storage space of your mobile phone (equivalent to the computer hard disk) is insufficient, which may be your TF card or the storage that comes with your mobile phone. Please check the default installation location of the program you set.
For example, we often say that the mobile phone memory configuration is 2GB/ 16GB, and 2GB refers to running memory, which is equivalent to computer memory; 16GB refers to the built-in storage space, which is equivalent to the hard disk of a computer.
Question 3: Why does the installation of software downloaded to mobile phones always fail? Solution: Settings-Phone Settings-Applications-Program Management: Software Installation-Select All, Online Certificate Check-Select Close. That's because the authority of the software security certificate is not enough. If you encounter that kind of software, you need to apply for a mobile phone signature certificate to download a signed software, sign the software to be installed on the computer and copy it to the memory card before you can install it. Simply put, you can download a "free signature" and make a certificate. Just sign your name when installing the software. This software is installed with the certificate that comes with your mobile phone. Or crack it, you can raise the system authority to the highest level. When installing, you can skip the certificate scanning stage and install directly. However, cracking is risky, so there is generally nothing to ask: I tried this, but I still can't install it?
Question 4: Why can't everything downloaded from my mobile phone be installed? Always prompt that the installation failed. I guess your system is Android?
Some parsing packages require a more advanced version to run. I estimate that most Android phones before 20 10 cannot install the updated mainstream software. If your phone kernel and hardware support a higher version of Android, you can upgrade your phone system, which should solve the problem. Now there are a lot of brushing software, and Baidu search is also a lot; It is also possible that the source file of the software you are downloading is damaged. It is recommended to download the latest version in official website. I personally suggest that Android software is a dime a dozen now, so don't download it on some small websites. Some junk software is likely to steal personal data. If you are a boy, don't download such software as "beauty XXX", many will be recruited. It is the same to look at Mito directly with a mobile browser, at least to ensure that it is "clean without leaving traces"; In addition, there are many reasons why the software cannot be parsed, opened and installed. If the problem can't be solved, please provide your mobile phone model, current system version and the name of the software you want to download, which is more convenient for you to answer quickly!
Question 5: Why can't my Android phone download anything? Try another browser!
Question 6: Why does Xiaomi's mobile phone installation software always prompt that the installation failed? 70 points may be a problem with the installation package. Download again and try to install. Or check that the phone's memory or storage space is insufficient, which will lead to failure. If you have security protection software, you need to check whether similar security shielding installation settings are set. Mobile phone settings-security-unknown source installation needs to be selected.
Check the above possibilities step by step.
Question 7: Why can't iPhone always install software? You don't associate introversion.
Question 8: What is the reason for the failure of mobile phone download and installation? Hello!
What are the tips for installation? You can refer to the following methods: ①. Prompt insufficient memory. It is recommended that you transfer the programs installed in your mobile phone to the sd card before using it. You can move the programs installed in your phone to the sd card by going to phone settings-General-Applications-Installed. If all the programs have been moved, but the memory is still insufficient, you need to uninstall several programs installed in your phone (that is, programs that cannot be moved) to free up space, and then install other programs.
(2) Prompt parsing error. The downloaded installation package may be damaged. It is recommended to download resources again for installation.
③ Prompt that it is not installed. Some software cannot be installed because the resolution is not supported, or the software or software version is not compatible with the mobile phone system. It is recommended that you change to another version or install other third-party software.

Question 9: Why can't I install any software on my Samsung phone? It always shows that the installation failed. Please try again later. If the phone can't install software/games, the suggestions are as follows:
1. Check whether the Unknown Source setting is turned on.
2. Check whether the machine supports the downloaded software format. The software format supported by Android phones is. APK format.
3. Please read the software details when downloading the software to see if there are any requirements for the machine operating system.
4. If you still can't install the software/game, it may be because the software version is low or there are compatibility problems between the software version and the system. It is recommended to download a new version and try to install it;
5. If it is invalid, back up the data (contacts, information, photos, etc. ) and try to restore the factory settings.
If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
Question 10: My mobile phone always prompts that the application installation failed. In fact, there are two kinds of mobile phone memory: 1 is mobile phone memory (RAM) and the other is ROM.
In this case, it is recommended to restart the phone before installation. If not, please format or restore the factory equipment.
Because mobile phones sometimes read software information repeatedly, when they read it repeatedly, they think that the memory of the mobile phone is insufficient (in this case, ROM).
And if the phone is not root, the system will occupy a lot of memory and storage.
